Lavender is still very easy to cultivate.
Cultivation method of lavender
It is a perennial shrub and can be used for about 10 years. Wide variety, easy cultivation, sunshine-loving, heat-resistant, drought-resistant, cold-resistant, barren-resistant and salt-resistant. The cultivation site needs sufficient sunshine and good ventilation. Time from sowing to flowering (or harvesting): 18 ~ 20 weeks. Lavender should be cultivated in large containers. But in order to prevent it from getting too wet, you can use a pottery jar or a smaller plastic jar, and don't use a big jar unless it is quite large.
Lavender can't stand high temperature and humidity, and it will die after being flooded for a long time. When planting outdoors, be careful not to let the rain directly rain on the plants. After May, it is necessary to move the place out of direct sunlight, increase ventilation to reduce the ambient temperature and keep cool, so as to spend the hot summer safely. Pay attention to sunshine, moisture, temperature and patience.
1. Soil: Suitable for weak alkaline or neutral sandy soil. Special attention should be paid to the selection of substrates with good drainage, which can be mixed with 1/3 pearl clay, 1/3 vermiculite and 1/3 sphagnum moss. If it is cultivated in the open field, pay attention to the drainage of the soil, and raise the mound into a border before planting.
2. Watering: Lavender doesn't like to keep water in its roots. After the first watering, water should be supplied when the soil is dry. The surface medium was dry and the inside was moist, and the leaves wilted slightly. Water in the morning, avoid the sun, and don't splash water on leaves and flowers, otherwise it will rot and breed pests and diseases. Continuous humid environment will make the roots grow poorly, there is not enough air to breathe, and even the whole plant will die suddenly. This is often the reason for the failure of lavender cultivation.
3. Illumination: Lavender is an all-day plant, which needs sufficient sunshine and a suitable humid environment. The environment that can give full sunshine is better, and it can grow in half sunshine, but there are few flowers. In summer, at least 50% sunlight should be blocked, ventilation should be increased, and the ambient temperature should be lowered, so that although the growth is weak, it will not die. Lavender can grow well on the flat ground in winter, so it should be cultivated in sunny places.
4. Temperature: Lavender is semi-heat-resistant, so it is cool. It likes warm in winter and cool in summer. The suitable growth temperature is 15 ~ 25℃, and it can grow at 5 ~ 30℃. Limit temperature: above 35℃, above 38 ~ 40℃ for a long time, and the top stems and leaves turn yellow. In northern winter, when the temperature is lower than 0℃ for a long time, the seedlings begin to hibernate, during which the seedlings can tolerate the low temperature of -20 ~-25℃.
5. Fertilization: When fertilizing, bone meal can be put into the pot soil as the base fertilizer (once every three months), and the seedling Shihuabao No.2 (20-20-20) can be applied again after the plant grows, such as Huabao No.3 (20-30-20). Apply light fertilizer.
6. Pruning: Lavender flower essential oil is the most abundant, and it is mainly used in flowers or inflorescences.
In order to facilitate the harvest, some small inflorescences in the early stage of cultivation may wish to be leveled with scissors, and the newly grown inflorescences are highly consistent, which is conducive to one harvest. Some varieties can be as high as 90 cm, and this method is also used to make plants low, promote more branches and flowers, and increase harvest. Pruning must be carried out after flowering, and the plant can be pruned to 2/3 of its original size, so that the plant type will be stronger and conducive to growth. Pruning should be carried out in cold seasons such as spring and autumn, generally in spring, and pruning in autumn will affect cold tolerance. When pruning, be careful not to cut off the lignified part, lest the plant weaken and die.
How to raise lavender well
Lavender is very easy to raise, just grasp a few principles, it is best to wash wet and drought-resistant, and get more sunshine. Don't water it often, but water the cultivation medium thoroughly.
Lavender likes loose neutral alkaline soil with good drainage. Garden soil can be used as culture soil; Coarse yellow sand; Peat; Organic fertilizer =4:3:2: 1, organic fertilizer must be decomposed. The prepared culture soil must be disinfected first. If possible, it can be fumigated with formalin or disinfected with steam. If the prepared culture soil is less, carbendazim powder can be added, which can also play a role in disinfection. Adjust the pH value to 7 ~ 7.5 with lime.
water
After the pot is put away, water it once. The principle of watering after survival is "see dry and see wet". Pay attention when watering: don't pour water directly on the leaves, and don't splash soil on the branches and leaves to avoid diseases. You can also spread a layer of pebbles on the soil surface of the flowerpot, which is beautiful and can prevent diseases. If tap water is used, it is best to use it in the sun for two days.
It doesn't need much fertilizer to fertilize lavender. In the spring with rapid growth (March-May), the compound fertilizer of nitrogen, phosphorus and potassium can be applied monthly to make a solution for irrigation, and the concentration is 1%. Too much nitrogen fertilizer can easily lead to excessive growth.
Do plastic surgery
After flowering, cut it off at the first node under the flower and trim the plant into a hemisphere by the way. Usually, dry the branches at any time. In order to control plant height or obtain better plant type, it should be cut again in late summer and early autumn to promote the development of new branches.
Eliminate pests and diseases
There are few pests. The disease is mainly root rot, and the incidence rate is the highest in high temperature and stagnant water environment. Control method: irrigate the roots with 800 times of carbendazim and chlorothalonil once a month, especially from June to 10. Pay attention to prevent water accumulation and keep the air dry.
illuminate
Lavender is a long-day plant, and light plays an important role in its development and the formation of aromatic oil. Excessive shading will lead to excessive growth and easy to get sick. In the family, lavender should be placed on the sunny balcony.
temperature
Lavender (L. Angus-Tiffany) in England can tolerate the absolute low temperature of -30℃ and the high temperature of 4 1℃, but the cool environment is the most suitable. French smoked clothes (L.stoechas) like warm environment and can tolerate low temperature of-10℃, so it can be planted in Shanghai.
humidity
Lavender likes dry environment, and regular watering is forbidden at home.
Turn over the pot and change the soil.
Lavender grows rapidly and needs to be changed once a year. In the first year, the seedlings should be flowerpots with a pot diameter of 12 ~ 16 cm, and in the second year, they should be replaced with flowerpots with a pot diameter of 20 cm.
How can lavender be cultivated to bloom quickly?
The habit of dressing grass:
I like warm climate, cold tolerance, drought tolerance, light preference and fear of waterlogging. Not strict with soil requirements, barren-resistant, like neutral and alkaline soil.
culture medium
Lavender likes loose neutral alkaline soil with good drainage. Garden soil can be used as culture soil; Coarse yellow sand; Peat; Organic fertilizer =4:3:2: 1, organic fertilizer must be decomposed.

Ask for an answer, how to raise lavender when you buy it?
Come on, the answer upstairs is so childish! ! You never planted lavender at first sight! ! People buy it from the supermarket. This is a potted plant. Do you think this is a fresh cut flower?
Generally, lavender bought back is delayed, that is to say, because the plants are weak, they can't see the sun and are directly blown by the wind! Rest in a cool, ventilated and dry place for three days, and then slowly move to a bright place when the situation improves! ! The most important thing is to establish the buds that have come out after the seedlings have recovered, because the finished flowers are born and not strong.
The lavender you bought should be feather lavender, which can't be eaten but can only be seen! This spider loves to dye red! Be careful not to drench the leaves when watering normally! ! Water the basin soil only when it is dry. Don't let the basin soil contain water! After all, the finished lavender sold in the supermarket is made of peat and perlite, which is not bad! !
How to raise lavender at home?
In fact, the most important thing to pay attention to is watering lavender. This is a very, very wet plant. Generally, the soil is poured thoroughly, and it is almost the same if it does not seep out. Also, when watering, remember not to drench the leaves and stems. Move it outdoors to bask in the sun when you have time. If it's so hot, keep it half-sun, not too sun. After summer, the problem is generally not big. This is a very hardy plant. Also, don't leave the rain outside to get wet just because it is nutritious. This is my personal experience, which hurts my skin.
What should I pay attention to when raising lavender?
Simple method:
1. Sunshine is necessary.
Sprinkle water once a day in summer, once every two days in winter and feed fertilizer once a month. It is best to use organic fertilizer.
3. If you plant a pot, trim it to 4 to 5 inches at the bottom of lavender after flowering. You need to change a big pot and add scientific mud.
4. In wet weather, it is necessary to trim the middle part to let it have air inflow.
5. The reserved part after pruning can be planted. (The best planting date is after beginning of autumn)
For more complex methods, you can also look at the following:
Don't soak lavender before planting, just control the moisture when sowing and don't let the seeds rot.
1, likes weak alkaline soil, requires looseness and good drainage.
2. Moisture requirements between dry and wet.
3, semi-heat-resistant, warm and humid environment in winter, cool and dry in summer, avoiding high temperature, high humidity and waterlogging.
4. Apply N and P base fertilizers frequently, and pay attention to appropriate K fertilizer, otherwise the fragrance of plants will weaken and the quality will deteriorate.
5. Seeds are sown in autumn. The optimum temperature for seed germination is 18-24℃, which requires light, 14-2 1d for germination; Proper shading is needed at the seedling stage, and frequent pinching is needed to promote more branches of seedlings. Seed plants have a long life and strong resistance to adverse environment, and they begin to bloom in the second year.
Lavender is semi-heat-resistant, so it should block at least 50% sunlight when cultivated on flat ground in summer. Although it is weak, it will not die, but it can grow well if it is cultivated in a cold place at an altitude of 1000 meters. On the contrary, lavender can grow well in a flat climate in winter, when the sunshine is weak, so it should be cultivated in sufficient sunshine.
Special attention should be paid to the selection of medium with good drainage when cultivating. After pouring enough water at one time, water the soil when it is dry, otherwise the roots will not grow well because of the continuous humid environment, or even the whole plant will die suddenly. This is often the reason for the failure of cultivating lavender. In addition, lavender flowers are the most abundant in essential oil, and flowers or inflorescences are often used as the main materials. In order to facilitate harvesting, some small inflorescences in the early stage of cultivation may be leveled with scissors, and the newly grown inflorescences are of the same height, which is conducive to one-time harvesting. Some varieties can reach a height of 90 cm. This method is also used to make plants low, promote branching and flowering, and thus increase the harvest. However, attention should be paid to pruning in cold seasons such as spring and autumn, and attention should be paid not to cut it into lignified ones.
Cultivation of Lavender There are four main propagation modes of Lavender: sowing, cutting, layering and rooting. At present, cutting is mainly used in production. Cuttings are usually carried out in spring and autumn. Softwood cuttings can also be used in summer. 1. Selection and treatment of cuttings: the quality of cuttings directly affects the survival rate of cuttings. Cutting should be carried out on well-developed plants, selecting annual semi-lignified branches with short pitch and no heading, and cutting at the top 8- 10 cm. The cut of the cutting should be close to the stem node and smooth as far as possible to avoid breaking the phloem. 2. Cutting method: plastic film cutting and soil preparation. Cover with plastic film after watering and cut immediately. 5-8 cm deep, 20-25 cm row spacing. Pay attention to raising ground temperature and promoting root development; Prune extended branches frequently, remove spikes in time, promote branching and cultivate strong seedlings. 3. Soil preparation: Lavender is drought-resistant and afraid of waterlogging, so it is advisable to choose plots with low water level, good drainage, deep soil layer and no saline-alkali land. Dig deep 25-27 cm. Before deep ploughing, 500kg of high-quality organic fertilizer (sheep manure), 0/5kg of phosphate fertilizer and 0/0kg of urea/kloc were applied as base fertilizer. 4. Planting: It is better to plant in autumn in Xinjiang, and the middle and late June of 10 is generally the best. The plant spacing is 60 cm, and the row spacing is 120 cm. Water immediately after planting. 165438+1At the beginning of October, cover the soil artificially to ensure the safe overwintering of seedlings. Spring ploughing can be chosen all over the Yangtze River basin. Second, field management 1, spring management: newly planted seedlings and perennial seedlings should be pulled out in time at the end of March of the following year, and watered when the climate picks up in early April, and key water should be poured to make the seedlings take root and the old seedlings turn green. After watering for a week, the seedlings should loosen the soil in time and keep warm. For old seedlings, urea 19 kg, calcium superphosphate 15 kg and oil residue 30 kg were applied per mu, and artificial deep ploughing was carried out between rows. This can play the role of fertilization, loosening soil, moisturizing and warming up, which is beneficial to the greening of lavender in spring. 2. Management from the growing period to the full flowering period: the newly planted small seedling plots should be watered with fixed root water. ~5 times, ploughing and weeding in time. The buds appearing before June 20 of the seedlings should be destroyed in time to promote the multi-branch of the plants, laying the foundation for the formation of yield in autumn of that year and high yield in the next year. There should be no weeds in the old rice field. ......
Planting and maintenance methods of lavender
Lavender is a genus of Labiatae, with about 28 species, distributed in Atlantic islands and Mediterranean regions to Somalia, Pakistan and India. There are only two kinds of cultivated plants in China. Plants are semi-shrubs or small shrubs, and rare herbs. Because cultivable varieties are widely cultivated in cultivation gardens all over the world, people can occasionally find wild lavender groups formed by floating seeds in gardens in many non-native places.
Planting and maintenance methods of lavender;
I. Planting methods
Lavender is semi-heat-resistant, and at least 50% sunlight should be blocked in summer in hot climate areas. Although it is weak, it will not die, but it can grow well when cultivated in cold places at an altitude of 1000 meters. On the contrary, lavender can grow well on the flat ground in winter, when the sunshine is weak, so it should be cultivated in sufficient sunshine.
Special attention should be paid to the selection of medium with good drainage when cultivating. After watering once, water the soil when it is dry, otherwise the roots will not grow well because of the continuous humid environment, or even the whole plant will die suddenly. This is often the reason for the failure of cultivating lavender. In addition, lavender flowers are the most abundant in essential oil, and flowers or inflorescences are often used as the main materials. In order to facilitate harvesting, some small inflorescences in the early stage of cultivation may be leveled with scissors, and the newly grown inflorescences are of the same height, which is conducive to one-time harvesting. Some varieties can reach a height of 90 cm. This method is also used to make plants low, promote multi-branch and flowering, and thus increase the harvest. But in cold seasons such as spring and autumn, attention should be paid to pruning, and firewood should not be cut.
Both sowing and cutting can be used for propagation, and sowing in autumn is suitable. Sowing in 128 grids is not easy to damage the roots when transplanting. The cutting method takes the terminal bud with 5 cm length as the material, and does not use the terminal bud with inflorescence, otherwise the root system will be poor and the growth will be poor in the future, because flowering means that the branches are aging, and the success rate of reproduction with aging branches is of course not good.
Second, the maintenance method:
Lavender likes cold or warm climate, but it can't stand hot and humid weather. When planting outdoors, be careful not to let the rain directly rain on the plants. Lavender doesn't like to keep water in its roots, and the cultivated soil needs good drainage, so it can be used after being mixed with 1/3 pearl clay, 1/3 vermiculite and 1/3 sphagnum moss. If it is cultivated in the open field, pay attention to soil drainage, and raise the mound into a border before planting. The cultivation site needs sufficient sunshine and good ventilation.
Don't water too much, just water the soil in the pot when it is dry, and try not to water the leaves and flowers, otherwise it will rot and breed pests and diseases. When applying fertilizer, you can put bone meal as base fertilizer in the pot soil (once every three months), Miao Shihuabao No.2 (20-20-20), and then apply a fertilizer with higher phosphate fertilizer, such as Huabao No.3 (20-30-20). Pruning must be carried out after flowering, and the plant can be pruned to 2/3 of its original size, so that the plant type will be stronger and conducive to growth.
Lavender needs plenty of sunshine and humid environment. It can grow in plenty of sunshine, but it has few flowers. When potted, it should not be watered too often, nor should it be preserved for too long to avoid root rot. In order to prevent excessive humidity, red clay pots (clay pots) or smaller plastic pots should be used, rather than large ones. Unless it has been propagated to a considerable scale, due to the use of small pots, it is necessary to pay attention to watering in time to avoid over-drying, and it is better to apply a small amount of fertilizer many times. Especially the flowering period is very long. Lavender likes cold and cool, and is not resistant to high temperature and high humidity. After May, it is necessary to move to a place out of direct sunlight, increase ventilation, reduce ambient temperature and keep cool, so as to spend the hot summer safely.
When and how to plant lavender, thank you ~~ 10.
Suitable for all night flower cultivation.
How many times should I water lavender every day? 10 point
Lavender doesn't need to be watered every day, just twice a week.
Lavender likes dry environment and is not resistant to humidity. It is not advisable to water regularly in the family, and it is not advisable to accumulate water in the basin soil or ground. Ventilation should be maintained. After the pot is put away, water it once. The principle of watering after survival is "see dry and see wet".
For newly planted lavender, sufficient irrigation should be ensured in the first three years to promote plant growth. Every year in the middle and late April, lavender should be watered in time during the greening period. Water it 6-8 times a year according to the weather and soil humidity. Pay attention to the key watering of bud water and flowering water, and water should be poured evenly and thoroughly to ensure the watering quality. Combined with timely intertillage for each irrigation, the purpose of moisture conservation, temperature increase and weeding can be achieved. Generally, intertillage weeds 5~7 times a year. 165438+1winter water irrigation in the first half of October.
How to cultivate lavender potted plants?
First of all, lavender
1. can be propagated by four methods: sowing, cutting, layering and rooting. But it is not easy to sow and germinate, and it takes a long time to grow into an ornamental plant.
I've tried many ways, but it's best to divide plants: go to a flower shop and sell a pot, and you can divide many pots.
2. When potted, you can choose a pottery basin or a smaller plastic basin to prevent it from getting too wet. It is not recommended to use a large basin unless it has grown to a considerable size.
3. An important feature of lavender is that it can't stand high temperature and humidity, and it will die if it is waterlogged for a long time. When planting outdoors, be careful not to let the rain directly rain on the plants. After May, it is necessary to move the place out of direct sunlight, increase ventilation to reduce the ambient temperature and keep cool, so as to spend the hot summer safely. Pay attention to sunshine, moisture, temperature and patience.
4. Soil: Suitable for weak alkaline or neutral sandy soil. You can dig some garden soil in flower beds or vegetable fields and mix one third of yellow sand with good results.
5, watering: rainy days, the air is humid, be careful not to water, to spray water; When the temperature is high in sunny days, water should be poured into the flowerpot every day to avoid dehydration and dryness.
6, lighting: lavender likes plenty of light and should be placed in a sunny place.
7. Fertilization: Put the organic granular fertilizer 10 bought by the flower shop once a month or so. Remember: it is better to apply less chemical fertilizer than more chemical fertilizer to avoid chemical fertilizer damage and burn plants.
Generally speaking, lavender is a herb that can tolerate extensive management. You put the potted plants in a slightly shaded place by other plants to avoid getting wet in rainy days, which is easier to maintain.
I have planted lavender for several years, and there are two varieties. These are all practical experiences. I hope it will help you:
