How to save the rotten roots of cultured bougainvillea? Bougainvillea flowers are colorful, and many people choose to plant bougainvillea at home. But when planting bougainvillea, the most worrying thing is the root rot of flowers. Let's take a look at how to save the rotten roots of bougainvillea.

How to save bougainvillea root from rotting 1? First, solve the root rot.

If most roots are healthy physically and mentally, and only a small part is rotten, you can cut off the rotten places and keep some of them healthy physically and mentally. After cutting, it can be placed in a cool place, and gas needs commodity circulation. Fill the flowerpot with shelf soil, then replant the main stem in the potted flowerpot and trim the leaves moderately to reduce water volatilization.

If the roots are about to rot, there is no way to save them according to the method of root pruning. You can cut off the branches that are healthy in body and mind and cut them again, so that you can get a new main stem. If the situation is serious, you can try this method.

Second, change the maintenance method.

1, reduce water, root rot will occur under normal circumstances, which is caused by excessive water release. It itself is afraid of waterlogging, so it must pay special attention to releasing water. The requirements for water are different in different seasons. The frequency should not be too high, and the water flow should not be too much at a time. Just water it.

2. The replacement of bonsai soil and the application of potted flower pots are very few, which will not be suitable for its growth and development, and the root system can not bend and stretch. You can change a new bonsai soil every year.

How to save the rotten roots of cultured bougainvillea? 2. First, trim the rotten roots. Then, when curing bougainvillea, if the root of bougainvillea is found to be rotten, don't throw it away at this time. First of all, we need to carefully observe how serious the root rot of bougainvillea is. If the rotten roots of bougainvillea are light, we will cut off the rotten roots of bougainvillea at this time and then disinfect the rotten roots of bougainvillea. We can replant it after its wound heals.

Second, the water is unreasonable.

Most flowers are most afraid of water in the basin bottom. Because too much water can't be drained in time, it will also lead to root rot. Because the roots of these flowers are in the water growth period for a long time, it is necessary to ensure that there is not too much water in the basin bottom of bougainvillea at this time. At the same time, the amount of water should be controlled when watering, and the soil in the basin should not be watered, but it should be watered thoroughly at one time. In summer, the amount of water should be increased appropriately.

Third, improve the soil.

When we were maintaining bougainvillea, we found that bougainvillea had rotted roots. If conditions permit, we suggest that you can change the soil for bougainvillea, or we can change the flowerpot for bougainvillea. Before changing the soil, choose the soil suitable for the growth of bougainvillea. At this time, we suggest that you choose loose and fertile soil, and at the same time, we can mix some sawdust or humus in the soil for bougainvillea. When changing the pot, we will change the old pot slightly. Generally speaking, as long as bougainvillea is rotten, the situation is not serious, so we can maintain bougainvillea according to the above three simplest operation methods, and there is no need to throw it away and replant it.

How to save cultured bougainvillea from rotten roots? 3 maintenance method:

Bougainvillea, also known as bougainvillea, bougainvillea, bougainvillea and towelling coverlet. The flowering period is from July to 65438+ 10, but it can bloom all year round as long as the temperature is suitable. The three bracts outside the flower are leaflike. I like hot and humid environment. I like strong light. The optimum growth temperature is 25 ~ 30%.

Bougainvillea bougainvillea flowers are peculiar and beautiful, and they were covered with branches when they were in bloom. Bougainvillea needs strong light, leaves and flowers fall in the semi-shade, and it is only suitable for viewing on the balcony with light or outside.

1, Selection of cultivation soil for bougainvillea bougainvillea

Culture soil consists of loam, cow dung, humus and sand. When used, add appropriate amount of bone meal. During cultivation, bougainvillea should be planted upright, filled with culture soil and watered. In the process of cultivation, you should always pick the core and form a clump of dwarf plants. You can also set up a bracket to let it climb up.

Families can use the following soil formula: garden soil: humus soil: sand = 5: 3: 2; Peat soil: humus soil: sand: perlite =5:2:2: 1.

2. A watering method for cultivating bougainvillea

Bougainvillea has a great demand for water, especially in midsummer. Lack of water is easy to cause defoliation and affect growth and flowering. Therefore, water is poured twice a day in summer flowering period, and water is sprayed in the morning, and 1 time is poured after 4 pm; After flowers wither, watering can be reduced appropriately, and too much soil moisture will cause fallen leaves and rotten roots; Control watering in winter, don't water the basin soil. However, water should be limited 4-5 weeks before bougainvillea blooms, that is, watering 1 time, and then watering after the leaves or buds droop, which is beneficial to the differentiation and formation of flower buds.

Triangle flowers like wet soil and are afraid of water stains. In spring, with the acceleration of growth potential, it is necessary to water it every day, and often sprinkle water on its leaves and surroundings to increase air humidity. If the air humidity is insufficient, it is easy to fall leaves. There are many bougainvillea flowers and leaves, which consume a lot of water in summer. It is best to water the soil once every morning and evening to keep the soil moist, and increase the number of sprinklers on its leaves and surrounding areas. Keep the soil moist after the temperature is cool in autumn. In late autumn, winter and early spring, when the temperature is low (about 65438 00℃), there is less water, which makes the soil in the basin dry. However, if the indoor temperature is kept above 15℃, it is necessary to water more to make the basin soil moist.

3. A fertilization method for bougainvillea cultivation

Bougainvillea likes fertilizer. After the weather gets warmer in spring, nitrogen fertilizer 1 time every/kloc-0 ~ 1 5 days, cake fertilizer1time every week during the growing period, and phosphorus fertilizer several times during the flowering period. Reduce the amount of fertilization after cooling in autumn and stop fertilization in winter. At the peak of growth and flowering, the potassium dihydrogen phosphate solution with the ratio of 1000 can be sprayed on the leaves for 2 ~ 3 times, or the "Huaduoduo" general fertilizer with the ratio of 1000 can be topdressing every10 day.

Stop fertilizing when the temperature is cool in autumn. Do not apply fertilizer when the temperature is low in late autumn, winter and early spring. However, if the temperature is above 15℃, the mixed liquid fertilizer can be applied every other month 1 time.

Bougainvillea is very sensitive to urea, and if it is not properly fertilized, it may lead to the phenomenon that leaves are flourishing and flowers are few, so it is necessary to be particularly cautious when applying urea.

Spring is the vegetative growth period of bougainvillea, and urea can be applied once per kloc-0/week. This can not only supplement the consumption of plants after flowering, but also promote the growth of new branches and lay a good foundation for reproductive growth.

Apply some thin liquid fertilizer in summer. When conditions permit, 0.2% ~ 0.3% potassium dihydrogen phosphate solution can be used as foliar topdressing, every half month 1 time. At the initial stage of flower branch growth, it is still necessary to apply 1 times urea to facilitate flower branch growth.

4. Requirements of light and temperature for bougainvillea cultivation

The suitable temperature for bougainvillea growth is 20 ~ 30℃, and it is easy to freeze and shed leaves when the temperature is lower than 5℃ in winter.

Bougainvillea likes light, and insufficient light in the growing season will lead to weak growth and affect flowering. In winter, it should be placed in a bright place, and the light should not be less than 8 hours a day, otherwise a large number of leaves will easily appear.

5. Matters needing attention in bougainvillea cultivation

(1) Bougainvillea is a light-loving plant. Whether it is planted in a pot or in the ground, it should be sunny. The plants treated by strong light have short internodes, full growth, many flowers, dark color and long flowering period. Insufficient light will cause the growth of new branches to be weak, the leaves will be dim, and there will be few or no flowers.

(2) Rectangular or oval purple sand pottery pots or glazed pottery pots are mostly used in bougainvillea bonsai, and the color should not be too deep to set off the gorgeous color of bougainvillea bracts. Potted soil should be mixed with humus-rich, loose and well-drained nutrient soil, and potted soil should be placed in spring when the temperature is relatively stable.

(3) After the temperature is cool in autumn, it can reduce the supply of water and fertilizer, make the basin soil moist and ensure sufficient illumination. When the temperature drops to about 10℃, people should be moved to a sunny place indoors or a sunny place on a closed balcony for cultivation. Because the indoor air humidity is low, water should be sprayed on its blades and surroundings frequently to increase the air humidity.

(4) Bougainvillea is not cold-resistant, and leaves will fall when the temperature is below 7℃ in winter. But leaves fall in winter, and will grow again after the temperature rises in spring, but the growth is not good. Therefore, it is best to keep the indoor temperature around 10℃ in winter. In winter, bougainvillea should be placed on the sunny windowsill, and different water and fertilizer management should be carried out according to different temperatures. Spray several times a day to improve the air humidity.

6. Pruning method of bougainvillea cultivation

The leaves and flowers of bougainvillea fall off a lot during flowering, so they need pruning after flowering. Potted plants are often cut into round-headed crowns or bundles, which require many branches and dense flowers to form gorgeous crowns. The ground planting needs to set up a bracket to climb on the shelf. You should always pluck your heart from the new branches. After changing pots, prune some over-dense branches, over-flourishing branches, dead branches and moth-eaten branches to promote more new branches. Pick the core from July to August, control the growth, promote the formation of flower buds and bloom vigorously. 5 ~ 6-year-old plants need to be cut short or pruned again 1 time.

7. A propagation method of bougainvillea cultivation

The propagation of bougainvillea mainly adopts cutting propagation, and the varieties that are not easy to take root by cutting can adopt grafting or high pressure propagation.

Cutting propagation: generally, after flowering in June-July, cut off the mature semi-lignified branches with the length of 65,438+00 ~ 65,438+05 cm, soak the cutting base with 20 mg/kg of indolebutyric acid for "hours", and then insert it into a sand bed or a spray seedbed. At the temperature of 2L ~ 25℃ and the relative humidity of 80% ~ 90%, 65. It can also be cut in greenhouse 65438 from June to March.

8. Flowering control of bougainvillea cultivation

The flowering period is mainly regulated by controlling water and promoting flowering. Select individuals with full crown and moderate growth, apply 1 growth fertilizer half a month in advance, and then start to control water. Generally, after 2 ~ 3 days, the leaves will wither and droop due to lack of water. At this time, spray water to protect the blades and keep the surface of the basin soil moist. After 2 ~ 4 weeks, loosen soil, water and fertilize, and keep it moist, supplemented by proper pruning, and then it can be transferred to normal management. When there are lateral branches in the leaf axils of branches, if you see thorns in the leaf axils and new branches with buds at the top, you will succeed. Of course, in order to make bougainvillea bloom all year round, it is necessary to adjust the light and temperature and apply sufficient fertilizer.

In addition, bougainvillea is a short-day plant. If it wants to bloom on National Day, it can be shaded from the beginning of August, that is, put the plant in a dark room 40 ~ 50 days in advance. Shading must be strict, and light leakage will not achieve the effect. Shading lasts for 45 days from 5 pm to 8 am the next day. When the room temperature is high, water should be sprinkled on the ground to cool down. Add 0.2% ~ 0.3% potassium dihydrogen phosphate foliar fertilizer 1 time every week during shading period.
