1. How to propagate Bougainvillea

What are the propagation methods of Bougainvillea and what are the methods and precautions for bougainvillea cutting

Bougainvillea cutting

< p> 1. The best time for cutting is spring, summer and autumn. In spring (March to April), pruned annual branches can be used for cutting after leaving the room (also called old-tech cutting), but the survival rate is not very high, only about 70%. Summer and autumn are the peak growth seasons of bougainvillea. Select the semi-lignified branches of the current year for tender cuttings, and the survival rate can reach more than 90%. As long as management is strengthened, it can bloom that year.

2. The cutting substrate is relatively random, and flower lovers can use local materials. The substrate can be coarse sand, fine sand, sandy loam with good permeability, loose soil that is not too fertile, or finely pounded burned briquettes, cinders, etc. Then add 0.1% carbendazim for disinfection, pile up the soil, and cover it with a film for 7 to 10 days. The slotting bed is 1 meter to 1.2 meters wide, 15 to 20 centimeters high, and the length is not limited.

3. Cutting processing: Select annual branches with short, thick internodes and cut them into 8 to 10 cm long, leaving only 2 to 3 leaves on the cuttings. Treating the cuttings with rooting hormone before cutting can promote early and multiple rooting.

4. The appropriate cutting depth is 3 to 4 cm (equivalent to 1/3 or 2/5 of the cutting). Before inserting, use a cutting stick to make a hole, then insert the cuttings, and press the substrate at the base of each cutting slightly to make the cuttings in close contact with the substrate. Then pour water once and cover it with film to keep it warm.

Notes:

1. Try to reduce the bacterial content of the cutting substrate (sand, cinder, soil, etc.). You can use various methods to disinfect the sand, such as exposure to the sun and watering with boiling water. Drenching, potassium permanganate or carbendazim sterilization, etc. The cinders should be fresh. For cuttings at the edge of the pot, the use of immature organic fertilizers and high-concentration chemical fertilizers should be minimized to reduce the chance of carrying bacteria and damaging the roots.

2. Place it in a cool place to reduce water evaporation.

3. Pay attention to keeping it moist, but not too much water. Too much water can easily breed mold and is not good for root development.

4. Bougainvillea is a southern flower that grows best in a soil environment with a pH value of 6.0 to 7.0. The water and soil in the north are highly alkaline, so ferrous sulfate solution can be applied once a month.

Propagation method of Bougainvillea

1. Propagation method: Cutting propagation is mostly used, but high pressure and grafting methods can also be used for propagation. The best time to take cuttings is from March to June. The general temperature is around 25℃, the humidity is 90%, and the shade is 70%. Roots can take place in about 30 days. High pressure and grafting propagation will take root in about a month.

2. Sand bed treatment before cutting: the new river sand does not need to be disinfected, just expose it to the sun. Used sand must first be cleared of impurities. It is best to level the sand bed after exposure to the sun and disinfect it with fungicide or potassium permanganate.

3. Selection of cutting branches: Strong branches free of diseases and insect pests can be used for cuttings. It is best to use semi-lignified branches, which will take root quickly. Generally, the length of cuttings is 20-30 cm. The length of lignified and thick ones can be 30 cm, and the length of semi-lignified ones is about 20 cm. Cut the bottom of the branch into a diagonal cut and the top into a flat cut. You can place a little yellow mud in the middle to retain the water and prevent it from evaporating easily.

4. Daily management and maintenance: After cutting, immediately pour enough root water. Pay attention to moisturizing and shade. After taking root, it should be transplanted into a pot in time. After setting the roots, place it in a sunny place. Pay attention to the control of water and fertilizer during the growth and flowering periods to achieve the effect of colorful flowers. According to the growth of seedlings, timely weeding, soil loosening, changing pots, changing soil, etc. Bougainvillea is prone to excessive branches. If left to grow naturally, the appearance will be unsightly. Therefore, the main work of bougainvillea management is topping, pot rolling, pruning, and controlling the tree shape. Shape design should be carried out in time before the branches are completely lignified, so as to shorten the time to cultivate them into the desired shape. Generally, a small amount of fertilizer can be applied to the soil during the growing and flowering stages. In soils with poor fertility, pay attention to the proportion of N, P, and K fertilizers, otherwise it will affect the differentiation of flower buds, causing the plants to only grow branches but not bloom. If managed well, it will bloom in one year.

How to grow bougainvillea

1. Soil: Bougainvillea has no strict requirements on soil. It grows well in well-drained, mineral-rich clayey soil, which is poor and alkali-resistant. , drought tolerant and avoid water accumulation.

Slightly acidic soil is most conducive to the growth of bougainvillea. 2. Watering: Watering should be done once a day in spring and autumn. In summer, water can be watered once in the morning and evening. In winter, watering should be controlled. After the flower buds appear, watering should be done once in the morning and evening, and at the same time, spray water on the leaves 1-2 times.

During the rainy season, water should be prevented to prevent plant root rot and death. 3. Temperature: The suitable growth temperature is 15-30℃. In summer, appropriate shade or water spraying, ventilation and other measures should be taken. In winter, the ambient temperature should be maintained at no less than 5℃.

4. Fertilization: In addition to applying sufficient base fertilizer in the pot soil, top dressing should also be applied during the growing season. Add a small amount of potassium dihydrogen phosphate and spray 0.1%-0.2% potassium dihydrogen phosphate solution on the leaves at the same time. Water alum fertilizer once a week during the flowering period and spray 0.2% potassium dihydrogen phosphate on the leaves.

5. Light: All year round, except for newly potted seedlings, they should be placed in a semi-shady place. In winter, it should be placed in front of a south-facing window, and the lighting time should not be less than 8 hours.

6. Propagation: Selection of cuttings: Bougainvillea branches as thick as arms and as thin as incense can be used for cuttings; thick branches take root late and form quickly; annual lignified green branches are prone to new roots. , high survival rate. Generally, choose 1-2 year old outer sunny branches with a tight and strong structure (do not use thin branches, immature branches, leggy branches, or shade branches.)

Use a sharp knife to cut into 3-4 sections (approximately long) 8-10cm), the lower beveled surface is 5-10 mm below the node, remove the lower leaves, and retain the upper two and a half (whole) leaves for cuttings. 7. Pruning: Bougainvillea has strong growth potential, so it needs to be pruned every year. Bougainvillea is often propagated by cuttings, and it is easy to raise seedlings. In May and June, cut mature lignified branches, 20 cm long, insert them into a sand pot, and cover them with glass. Keep it moist, it will take about a month to take root, and it will bloom after two years of cultivation.

Pruning method: Prune appropriately after flowering, cut off the peduncles, retract 1/3 of the flower branches, and thin out weak branches, short branches, and inner branches. In winter, pruning should be combined with changing the potting soil. The pruning should be short, heavy and sparse.

Short means short cutting, retaining 1/3 of the branches; heavy means pruning long flowering branches; sparse means thinning out weak branches so that strong branches can grow again, also called renewal pruning, cutting off The branches can be reserved for seedling cuttings. In the South, bougainvillea trees are used for flower stands, fences, and doorways. They do not go dormant or lose leaves in winter, and only do light pruning. However, they should be tied, distributed, and pulled so that the branches of the flower stand are evenly and reasonably distributed and covered with the flower stand.

8. Disease and insect pest control: Bougainvillea brown spot disease damages the leaves, producing yellowish-brown to light brown lesions with a diameter of 0.1-0.5 cm on the leaf surface. When a small number of diseased leaves are found, remove and burn them in time. In the early stage of the disease, use 70% manganese zinc wettable powder 400 times, spray once every 10 days, 3 to 4 times in a row.

The lesions of Bougainvillea leaf spot are initially yellow-brown with a yellow-green halo around them, and then expand into nearly round or irregular lesions with dark brown edges. In the later stages, the lesions appear Small black dots. If you find a small number of disease spots, you can apply Daknin cream ointment on them, and cut off the branches with more disease. In the early stage of the disease, you can generally use 50% carbendazim wettable powder 500 times to prevent and control it, and spray it once every 7-10 days. In serious cases, according to actual experience, spray again on the fourth day, and then every 7 days.

3-4 times in a row, the control effect is good. Scale insects: In an environment with poor lighting, poor ventilation, high temperature and high humidity, various scale insects are prone to piercing and sucking damage. They can be sprayed with 45% malathion EC 1000 times to kill them.

How to propagate Triangle Flowers

How to propagate Triangle Flowers? Propagation by cuttings: From June to July, cut mature lignified branches after flowering, 15-20 cm long, soak the base of the cuttings with 0.8% acetic acid, and then insert them into the sand bed to maintain high air humidity and a temperature of 21-21 27℃, 30 days for rooting.

Layering propagation: carried out from June to July. For varieties that are difficult to root, the high-altitude layering method is generally used.

Peel the stems 15-20 cm away from the top in a circular shape, with a width of 1.5 cm. Wrap it with leaf mold and plastic film. It will take about 2 months to heal and take root. Cut it and pot it in autumn. Grafting propagation: Usually in spring when the temperature is above 15°C, 3-4-year-old common triangular flowers are used as rootstocks, and double-petaled and other fine varieties are selected as cuttings, 5-10 cm long, propagated by cleft grafting or branch grafting. It takes 40-50 days to heal and sprout new shoots.

This method is commonly used for potted plants or bonsai.

How to cultivate bougainvillea and what to pay attention to, how to take cuttings

Bougainvillea is also known as triangle flower, bougainvillea, bougainvillea, and treasure towel.

The flowering period is from July to October, but as long as the temperature is suitable, it can bloom all year round. The three outer bracts of the flower are leaf-like.

Likes a high temperature and humid environment. Like bright light.

The optimum temperature for growth is 25~30%. The flowers of bougainvillea are strange and beautiful, and they cover the branches when they bloom.

Bougainvillea needs strong light and will fall leaves and flowers in semi-shade, so it is only suitable for viewing on a balcony with sunlight or on a balcony shelf. 1. Soil selection for bougainvillea cultivation. The culture soil is made of loam, cow dung, leaf humus soil, sand, etc., and is well-rotted. When using, add an appropriate amount of bone meal.

During cultivation, bougainvillea should be planted upright, filled with soil and watered thoroughly. During the cultivation process, the plants should be pinched frequently to form a clustered and low plant type.

A bracket can also be set up to allow it to climb up. The following soil formula can be used at home: garden soil: leaf mold soil: sand = 5:3:2; peat soil: leaf mold soil: sand: perlite = 5:2:2:1.

2. Watering methods for bougainvillea cultivation Bougainvillea has a large demand for water, especially in midsummer. Water shortage can easily cause leaf fall, affecting growth and flowering. Therefore, water twice a day during the flowering period in summer, spray water in the morning, and water once after 4 p.m.; watering can be appropriately reduced after the flowers fade, as overly wet soil will cause leaf fall and root rot; control watering in winter, and pot soil Do not dry or water.

However, water should be withheld 4 to 5 weeks before the bougainvillea blooms. That is, after watering once, wait until the leaves or buds droop before watering again, which is conducive to the differentiation and formation of flower buds. Triangle flowers like moist soil and are afraid of water damage.

In spring, as the growth rate accelerates, watering is required every day, and watering is often applied to the leaves and surrounding areas to increase the air humidity. If the air humidity is insufficient, the leaves will fall easily.

Triangle has many leaves and consumes a lot of water in summer. It is best to water it once a day in the morning and evening to keep the soil in a moist state and increase the number of times of watering its leaves and surrounding areas.

After the temperature cools down in autumn, just keep the pot soil moist. In late autumn, winter, and early spring, when the temperature is low (around 10°C), water less to make the pot soil dry.

However, if the indoor temperature remains above 15°C, watering should be more frequent to keep the pot soil moist. 3. Fertilization method for bougainvillea cultivation. Bougainvillea loves fertilizer. After the weather warms up in spring, apply nitrogen fertilizer once every 10 to 15 days. Apply cake fertilizer and water once a week during the growth period. Apply phosphorus fertilizer several times during the flowering period.

Reduce the amount of fertilizer after autumn cools down, and stop fertilizing in winter. During the peak growth and flowering season, 1,000 times potassium dihydrogen phosphate solution can be sprayed on the leaves 2 to 3 times, or 1,000 times "Huaduoduo" general fertilizer can be topdressed once every 10 days.

Stop fertilizing in autumn when temperatures cool down. Do not fertilize when the temperature is low in late autumn, winter and early spring.

However, if the temperature is above 15°C, mixed liquid fertilizer can be applied once every other month. Bougainvillea is very sensitive to urea. If fertilizer is not applied properly, it may cause luxuriant branches and few flowers, so be particularly careful when applying urea.

After the flowers fade in spring, it is the vegetative growth period of bougainvillea. Urea can be applied every 1 week. This can not only supplement the consumption of the plant after flowering, but also promote the growth of new branches, laying a good foundation for reproductive growth.

In summer, some liquid fertilizer should be applied lightly. If possible, 0.2%~0.3% potassium dihydrogen phosphate solution can be used as top dressing on the leaves, once every half month. In the early stages of flower growth, urea still needs to be applied once to facilitate the growth of flower branches.

4. The light temperature requirement for bougainvillea cultivation requires that the suitable temperature for bougainvillea growth is 20~30℃. In winter, when the temperature is lower than 5℃, it is susceptible to freezing and falling leaves. Bougainvillea likes light. Insufficient light during the growing season will cause the plant to grow weak and affect flowering.

In winter, it should be placed in a brightly lit place, and the lighting should not be less than 8 hours a day, otherwise a large number of leaves will easily fall. 5. Precautions for cultivating bougainvillea (1) Bougainvillea is a light-loving plant. Whether it is potted or planted on the ground, it must have sufficient sunlight. Plants treated with strong sunlight will have short internodes on branches, substantial growth, large number of flowers, and deep color. The flowering period is long.

Insufficient light will cause weak growth of new branches, dull leaves, and little or no flowering. (2) Bougainvillea bonsai usually uses rectangular or oval purple sand pottery or glazed pottery pots. The color should not be too dark to bring out the gorgeous color of the bougainvillea bracts.

The potting soil should be rich in humus, loose and well-drained nutritious soil, and potting should be carried out in spring when the temperature is relatively stable. (3) When the temperature cools down in autumn, the supply of water and fertilizer can be reduced, and the pot soil can be moistened to ensure sufficient light.

When the temperature drops to about 10℃, it should be moved to a well-lit indoor place or a sunny place on a closed balcony for cultivation. Because the indoor air humidity is low, water should be frequently sprinkled on the leaves and surroundings to increase the air humidity.

(4) Triangle flower is not cold-tolerant and will lose its leaves when the temperature is lower than about 7℃ in winter. However, those that lose their leaves in winter will re-grow leaves after the temperature rises in spring, but the growth will not be good.

Therefore, it is best to keep the room temperature around 10°C in winter. In winter, triangle flowers should be placed on a windowsill with sufficient sunlight, and different water and fertilizer management should be carried out according to different temperatures.

It should be sprayed around several times a day to increase the air humidity. 6. Pruning and pruning methods for bougainvillea cultivation. Bougainvillea leaves and flowers fall frequently during the flowering period, and they need to be pruned after flowering.

Potted plants are often cut into a round crown or tied shape, requiring many branches and dense flowers to form a gorgeous crown. Ground planting needs to be set up with supports so that it can be climbed onto the shelves.

New branches should be pinched frequently. After repotting, prune some overly dense branches, leggy branches, dead branches, and diseased branches to promote more new branches.

Topping is carried out from July to August to control growth and promote the formation of flower buds and vigorous flowering. Plants that are 5 to 6 years old need to be shortened or pruned and renewed once.

7. Propagation methods for bougainvillea cultivation Bougainvillea is mainly propagated by cuttings. For varieties that are not easy to take root, grafting or high-pressure propagation can be used. Propagation by cuttings: Generally, mature semi-lignified branches are cut after flowering in June to July, with a length of 10-15 cm. The base of the cuttings is soaked with 20 mg/kg indolebutyric acid for an hour, and then inserted into a sand bed or spray seedbed. Under the conditions of 2l~25℃ and relative humidity of 80%~90%, roots will take place in about 1 month.

Cuttings can also be taken in the greenhouse from January to March. 8. The flowering period of bougainvillea cultivation is mainly controlled. Use water to promote flowering to adjust the flowering period.

Select individuals with plump crowns and moderate growth. Apply growth fertilizer once half a month in advance, and then start controlling water. Generally, the leaves will grow after 2 to 3 days. If it wilts and droops due to lack of water, sprinkle water to protect the leaves and keep the surface of the pot soil moist. After 2 to 4 weeks, start loosening the soil, watering, fertilizing, and keeping it moist, and then add supplements. With proper pruning, it can be transferred to normal management. When the side branches are pulled out from the leaf axils of the branches, and if there are thorns in the leaf axils of the new branches and young bracts at the top, it will be successful.

Of course, it is necessary. To keep bougainvillea flowers blooming all year round, you must also adjust the light and temperature.

How and when to cut bougainvillea?

The most common planting method is cutting propagation, and it is easy to raise seedlings.

In May and June, cut mature lignified branches, 20 cm long, insert them into a sand pot, cover them with glass, and keep them moist. They will take root in about a month and bloom after two years of cultivation. The flowering period of the whole plant is very long, up to three or four months.

During the flowering period, there are many fallen flowers and leaves, which need to be removed in time to keep them fresh and beautiful. Bougainvillea grows on a vine and is easy to propagate.

You only need to cut its stems into the soil in early spring or late autumn, and they will take root and grow branches and leaves in a month. It will bloom in the second year.

Its flowering period is generally around January. In the south, the general flowering period is from October of the current year to early June of the following year.

Extended information: The soil requirements for selecting culture soil are not strict, but it is afraid of water accumulation and cannot tolerate waterlogging. Therefore, it is necessary to choose loose and well-drained culture soil. Generally, 4 parts of humus soil and garden soil can be used. The culture soil prepared with 4 parts and 2 parts sand can also be made of sun-dried pond mud mixed with some coal cake residue as pot soil.

It is a small evergreen shrub with eye-catching bright red flowers and large flowers. Every three bracts gather into a small triangular flower, so it is also called the triangle flower. Bougainvillea prefers warmth and sufficient light, but is not cold-tolerant and avoids waterlogging.

It is suitable for growing in fertile, loose, well-drained sandy soil. It will not only grow poorly in heavy, alkaline, low-humidity and easy-to-waterlog soil, but also prone to root rot and death. The culture soil should be prepared with 4 parts of leaf mold soil, 2 parts of garden soil, 1 part of decomposed manure, 1 part of sawdust and 2 parts of river sand. When potting, 30g of decomposed dumpling fertilizer should be added as base fertilizer.

It requires certain nutrients and appropriate fertilization during the growth period to meet its growth needs. Fertilizer should be well decomposed, and fertilization should be applied in small amounts and multiple times, and the concentration should be light. Otherwise, it will easily damage the root system and affect growth.

Starting from May, apply 10%~15% cake fertilizer once every half month to promote the growth of spring shoots; in the high temperature season from July to August, in order to meet their growth needs, fertilizer should be applied every 15~ Apply 10% cake fertilizer and a small amount of superphosphate or a small amount of compound fertilizer once every 20 days; after September, less nitrogen fertilizer should be applied, and burnt mud and a small amount of superphosphate can be used to promote the bright red leaves of the bracts. Bougainvillea requires less water than other flowers. During the growth period, as long as the pot soil is neither dry nor wet.

Reasonable fertilization To make it bloom, sufficient nutrients must be ensured. At the same time, fertilization must be timely and appropriate and used rationally. Generally, during the peak growth period from April to July, liquid fertilizer should be applied every 7 to 10 days to promote strong plant growth. The fertilizer can be 10% to 20% decomposed bean cake, rapeseed cake water or human excrement water.

Starting in August, in order to promote the growth of flower buds, fertilize mainly with phosphorus fertilizer. Fertilize once every 10 days. You can use 20% of liquid fertilizer such as decomposed chicken, duck, pigeon manure and fish offal. The flowering period begins in October. From this time to mid-November, fertilizers based on phosphate fertilizer need to be applied every half month, with a fertilizer-water concentration of 30% to 40%.

In the future, top dressing must be applied after each flowering, so that nutrients will be continuously supplemented during the flowering period. Control water before flowering. When watering, follow the principle of "don't water it dry, water it thoroughly".

But in order to bloom neatly and profusely, water must be controlled before blooming. Begin to control the watering of Bougainvillea from September. Each watering should wait until the pot soil is dry and the branches and leaves are soft and drooping. Repeat this for half a month, and resume normal watering after half a month.

Do not apply fertilizer during the water control period to avoid fertilizer burning the roots. In this way, buds and flowers will appear in about a month, and the flowers will bloom neatly and prosperously.

Loosen the soil and change the pot. Due to long-term watering, fertilization and rain erosion, the pot soil is easy to harden. Therefore, the soil must be loosened regularly and the weeds in the pot soil must be removed to facilitate the growth of bougainvillea. Otherwise, the pot soil will become hardened and water will accumulate, which may easily cause root rot or poor growth.

In addition, bougainvillea grows faster, has a developed root system and many fibrous roots, and needs to be repotted once a year. Geographical distribution Native to Brazil.

It is cultivated in courtyards and parks in southern China and in greenhouses in northern China. In China, it is distributed in Fujian, Guangdong, Hainan, Guangxi, and Yunnan.

When to cut bougainvillea, bougainvillea cutting methods and illustrations

Bougainvillea has a long flowering period and unique flower shape. Its petals have only three petals and the petals are triangular, so bougainvillea is also known as It's called triangle flower, bougainvillea.

Bougainvillea is native to Brazil and is a tropical flower plant, so it can grow well in the south, but it requires more care in the north. Propagation by cutting is a commonly used propagation method of bougainvillea. When is the best time to take cuttings of bougainvillea? Although bougainvillea can be cut all year round, due to the differences between the north and the south, many florists do not know the suitable time for bougainvillea cutting in the north and south, which leads to problems such as low survival rate and unsuccessful cutting. Bougainvillea is generally The survival rate of cuttings is relatively high in summer. At this time, both the temperature and air humidity are very suitable for bougainvillea to grow in the south. When is the best time to cut bougainvillea? The suitable temperature for bougainvillea cuttings is around 20-30°C. Southern bougainvillea often chooses to take cuttings from May to June. At this time, spring is warm and flowers are blooming, and the climate conditions are very suitable.

In the north, bougainvillea is usually cut from February to April. At this time, the bougainvillea cuttings grow more vigorously, the temperature and humidity are more suitable, they are less susceptible to frost damage, and the survival rate is greatly improved. 2. Bougainvillea cutting method and illustration 1. Preparing the plant Bougainvillea can be cut from young branches or old branches. Generally, cuttings from old perennial branches are used.

It is recommended to use old branches for cuttings of bougainvillea. Old branches have strong vitality, are easy to develop healing tissue, take root quickly, and are easy to survive. Some old branches with latent flower buds will bloom soon after the cuttings are taken. Therefore, when preparing cuttings of plants, healthy old branches with strong vitality are generally selected.

2. Prepare the potting soil. The cutting substrate (potting soil) of bougainvillea generally includes sand, soil and cinder. The substrate of sand inserts is generally a mixture of coarse sand and river fine sand, so that the breathability and water retention requirements are met. If conditions permit, it is best to use this substrate.

The substrate for soil cuttings is usually dredged and well-permeable soil, and cuttings can be made on the edge of the pot soil. For cinder cutting, briquettes from the pot are selected, and the cinders are crushed into small pieces and put into pots for cutting. Of course, this kind of substrate may not be common.

3. After the bougainvillea flowering period, cut the 20cm old branches and insert them into the prepared substrate, water them enough, and place them in a cool and ventilated place. When taking cuttings in spring and autumn, you should water them once a day.

Although bougainvillea is a tropical flower plant, it is still worth paying attention to how to care for bougainvillea in summer. In summer, bougainvillea needs to be watered once in the morning and evening. In winter, the amount of watering must be strictly controlled for cuttings, mainly by spraying water on the leaves to maintain humidity. Bougainvillea can take root in about 30 days after cutting. If the temperature is low during the cutting season, It will affect the survival rate of bougainvillea.

3. Precautions for bougainvillea cuttings 1. To disinfect the pot soil, try to reduce the bacterial content of the bougainvillea cutting substrate selected. Various methods can be used to disinfect the sand, such as exposure to the sun, boiling Pour the sand with water, or use potassium permanganate, carbendazim, etc. to sterilize. In short, the substrate must be thoroughly disinfected. 2. Pay attention to fertilization. After cutting, try to minimize the application of immature organic fertilizers. High-concentration chemical fertilizers must be applied with caution. High-concentration chemical fertilizers can easily damage the roots and seriously affect the survival rate of the bougainvillea.

3. Place in a cool and ventilated place. After the bougainvillea cuttings are completed, they should be placed in a cool and ventilated place to reduce the evaporation of water. Be sure to keep the pot soil moist, but it should not be too moist. Too much water can easily breed bacteria, causing the bougainvillea leaves to turn yellow, and is not good for rooting.

4. Cutting time: Bougainvillea is best cut in September-October or February-April. The temperature and humidity are more suitable, and the mold activity is not strong and the plants are not strong. Once infected, the healing tissue will easily form new roots. Summary: Through the above introduction to the bougainvillea cutting time and bougainvillea cutting method, I believe everyone has a certain understanding of when to cut bougainvillea and the precautions for cutting. I hope that flower friends can cultivate beautiful bougainvillea flowers! .

Bougainvillea cuttings are actually very simple. Remember these points, and they will take root in 20 days

Bougainvillea cutting tips

Cut bougainvillea ears

p>

Do not use young branches to cut bougainvillea. Use one-year old branches to make them easier to survive. Cut off healthy old branches about 8 to 10 centimeters, cut off the lower leaves, and leave two or three leaves on the top. Cut the lower cutting surface into a bevel and place it in a ventilated and cool place to dry for half to an hour to allow the wound to dry naturally.

Soaking bougainvillea cuttings

Bougainvillea can take root quickly by doing this: If you want to ensure the rooting rate of bougainvillea cuttings, you can soak them in rooting powder overnight to induce callus, and then Dry the cuttings and share with you the exclusive secret recipe. Soak the bougainvillea cuttings with honey and sugar mixed with water. The rooting rate is 100%, which I don’t tell ordinary people.

Key points for cuttings

The seedbed for bougainvillea cuttings can be humus soil with good water permeability, or you can use river sand seedbed. I suggest using river sand cuttings to have a higher rooting rate, regardless of For cuttings, I recommend using river sand for cuttings. Insert the bougainvillea branches that have been dried or soaked in rooting powder about 3 to 4 centimeters into the river sand. Keep the river sand moist and place it in a cool and ventilated place for curing. Do not leave it in the sun. Avoid direct sunlight and do not irrigate with large amounts of water.

If the temperature over there is not high enough and the humidity is low, cover the pot with a plastic film after cutting the bougainvillea, which can both moisturize and keep heat, and rooting is more guaranteed. If the air is too dry, there is no need to wait. Rooted branches and leaves have lost water and dried up.

Transplanting the bougainvillea into pots

After the bougainvillea has taken root, you can start transplanting it into pots. I suggest you directly use bags to fill the sand cuttings, which are easy to transplant and repot. When doing so, you should pay attention to the fact that the potting soil must be permeable to water and air. Don't press the potting soil too firmly. Move the pot and water it once, then place it in a cool and ventilated place to slow down the seedlings. After the water dries, move it to a sunny place for normal maintenance.

My personal opinion on bougainvillea propagation by cuttings: Bougainvillea propagation by cuttings is a common propagation method. When selecting bougainvillea branches, it is best not to select young branches. Do not damage the cortex of the branches when pruning. It is best to cut it flatly with a knife. If you want the cutting to take root quickly, you can soak it with bees and sugar water for one night and then dry it naturally. The cutting will take root in half a month. After cutting, be sure to ensure the temperature and humidity, especially the humidity. If not It is best to cover it with a film to avoid water droplets and mist. Cover it tightly in the morning and evening, and let it breathe at noon. When transplanting into the pot, be sure to remove the mud balls, otherwise it will easily damage the roots

The cutting method of bougainvillea and Time

The following measures are adopted for the propagation of Bougainvillea: cutting, high-altitude layering and splitting, mainly the cutting method, and the cutting substrates are sand cutting, soil cutting and cinder cutting respectively.

Sand planting: Both coarse sand and fine sand can be used. Coarse sand and fine sand have slightly better permeability. Fine sand has slightly stronger water retention capacity than coarse sand. Each has its own merits. Flower friends can use local materials according to local conditions. that is.

Soil cutting: Choose sandy loam with good permeability or loose loam that is not too fertile. You can also make cuttings on the edge of the flower pot.

Cinder cutting: Choose burned briquettes and cinders, pound them into fine pieces and put them into pots for cutting.

Selection of branches: Generally, annual mature branches are used, large perennial branches can also be used, and cuttings of young branches can also be used.

High-altitude layering: circumcise the branches that need to be propagated, then use plastic film to cover the soil, and use discarded syringes to inject water into them to keep them moist. When more new roots grow, cut them and plant them in pots. Just hit it. Sometimes it is found that some roots grow on the old branches of bougainvillea during the mild rain season. You can also cut them directly and plant them in a pot and place them in a cool place, and they will survive easily.

Split the plant: For a plant with very low branches, after the two branches are separated, they can carry part of the root system. They can be split directly and divided into two plants for planting in pots. Potted flowers that survive after being divided into pockets must be grown in that year. Will bloom.

Twig cuttings: In the mildew season from May to June, insert the twigs into a sand tray and place them in a cool place to keep them moist. They can also take root and survive. However, because the twigs are too small and have low nutritional content, It has poor resistance and requires strict conditions for substrate disinfection and management. It is not easy to form large potted flowers after survival.

Cuttings of annual branches: Choose thicker annual mature branches with dense internodes, cut them into 5-6 inches long, and cut them. Branches with sparse internodes should have more than 3 buds. Generally, the coarser ones are chosen to have a higher survival rate.

Cuttings of perennial large branches: Renewed old branches, large branches cut into appropriate lengths (choose the appropriate shape to ensure more than 3 buds) are cut and the same will take root and survive. Generally, enthusiasts do not plant many. It is recommended to use large branch cuttings. Because the body is rich in nutrients and has strong vitality, it is easy to form healing tissue, and the roots are also fast, making it easy to survive and take shape. Some large branches with latent flower buds will bloom soon after being transplanted. Some can take shape and bloom that same year.
