What are the precautions for planting lavender on a large scale?
Lavender is a herbaceous plant that many people are very familiar with. Its management is extensive and its cultivation difficulty is relatively low, so it is also loved by many flower enthusiasts. However, planting lavender on a large scale still requires attention to many issues. How to improve the germination rate, and how to manage the seedling stage? Let me introduce this to you.
Lavender
1. Level the ground and water it thoroughly. Choose soil with good drainage. The size of the leveled seedbed can be determined by the amount of seed. The sowing area per kilogram of seed is about 100 sq m. Then water the seedbed thoroughly, and add an appropriate amount of phoxim to prevent insect pests.
2. Seed treatment. To improve the germination rate of lavender seeds, soak them before sowing. First soak them in clean water for 12 hours, then soak them in gibberellin for 6 hours. The gibberellin should be dissolved with strong liquor or alcohol, at a ratio of 4 jin of water per gram of gibberellin.
3. Sow and cover with soil. To sow evenly, we can mix the seeds with a basin of fine soil, then scatter them. Then cover with soil. The covering soil should be even, based on a thickness 2-3 times the size of the seeds.
4. Keep warm. Cover the entire seedbed with plastic film to retain moisture, and add a shade net to prevent direct light. In the eighth and ninth lunar months, when the temperature is around 20°C, seedlings can emerge in 5-6 days, and the young seedlings will basically all be out in 7-8 days.
5. Management during the hardening-off stage. After the lavender seedlings emerge, we remove the plastic film and shade net, and at the same time spray a fungicide to prevent seedling rot. Generally, use one bag of metalaxyl and fludioxonil mixed with 15 kg of water, spraying three times in a row at five-day intervals.
Management methods for sowing lavender on a large scale
October 10 news from China Landscape Web: As a herbaceous plant, the purple and romantic lavender is loved by people. Because of its extensive management and easy cultivation, lavender manors, lavender flower sea landscapes, and large-scale lavender planting bases continue to emerge across our country. So how can large-scale sowing of lavender improve the germination rate, and how should the seedling stage be managed? Below we introduce the sowing and management methods of lavender:
1. Level the ground and water it thoroughly. Choose soil with good drainage. The size of the leveled seedbed can be determined by the amount of seed. The sowing area per kilogram of seed is about 100 sq m. Then water the seedbed thoroughly, and add an appropriate amount of phoxim to prevent insect pests.

Generally, use one bag of metalaxyl and fludioxonil mixed with 15 kg of water, spraying three times in a row at five-day intervals.
Once the young seedlings grow to about 10 cm, they can be transplanted. The above lavender sowing methods are summarized from many years of experience and can be used as a reference for large-scale sowing.
How to grow lavender (which month to plant) - Lavender planting methods and precautions
When lavender is mentioned, many people must feel a sense of happiness. The purple petals make people feel romantic and beautiful. The reason lavender is so loved by people now is indeed inseparable from its appearance. Lavender has high value. Besides being ornamental, it can also be eaten and used for beauty, so many people now want to plant it.
How to grow lavender (which month to plant)
Lavender can be cultivated by sowing or cuttings. Sowing can be done in spring (March to June) or autumn (September to November) each year, and germination takes about 15 days. If you buy a planted pot from a flower shop, you can also propagate it yourself by cuttings. You can choose the terminal bud (about 5 cm to 10 cm), remove the leaves from the bottom 2 nodes, soak it in water for 2 hours, then insert it into the soil. It will take root in about 2-3 weeks. The cutting medium can be 2/3 coarse sand mixed with 1/3 peat moss.
Lavender planting methods
1. Sowing method: Generally, for seeds that are slightly larger (such as lavender and sage), you can sow 2-3 seeds per container. After germination, keep one stronger seedling depending on the growth condition of the young seedlings. For very small seeds (such as marjoram), you can broadcast them. Dip your hand in some seeds and gently scatter them on the soil. After germination, thin the seedlings. Keep 1-3 young seedlings as appropriate.
2. Covering seeds with soil: The thickness of the soil covering the seeds depends on the size of the seeds, generally 2-3 times the diameter of the seeds. For very small seeds, the soil should be thinner. Lavender seeds are large, so they can be covered with thicker soil. Some seeds are strongly phototactic and do not need to be covered with soil (such as lemon balm and rosemary).
3. Watering: Lavender does not like water remaining around its roots for long periods. After watering thoroughly once, water again only when the soil is dry, to the extent that the surface growing medium is dry and the interior is moist, and the leaves are slightly wilted. Water in the morning, avoid sunlight, and do not splash water on the leaves and flowers, otherwise they will easily rot and breed pests and diseases. A continuously humid environment will prevent the roots from having enough air to breathe and cause poor growth, or even sudden death of the whole plant. This is often where lavender cultivation fails.
Precautions for planting lavender
1. For newly planted young seedlings and perennial seedlings, remove the soil and release the seedlings at the end of May the following year. Water when the temperature rises, and water well the key water for settling the roots of young seedlings and for the greening of old seedlings. Loosen the soil one week after watering to preserve moisture and raise the temperature. For old seedling fields, apply 19 kg of urea, 15 kg of superphosphate, and 30 kg of oil residue per 667 sq m, apply them between the rows, and deeply turn the soil manually. This serves the functions of fertilizing, loosening the soil, preserving moisture, and raising temperature, and is beneficial to the spring greening and growth of lavender.
2. For plots with newly planted young seedlings, water well the root-settling water, water 4-5 times a year, and timely carry out intertillage and weeding. The flower buds appearing on young seedlings before June 20 should be removed in time to promote the plant to produce more branches, laying the foundation for forming yield in the autumn of that year and high yield the following year. For old seedling plots, ensure there are no weeds in the field, water well the budding water in early May, and water well the flowering water in June.
Prevention and control of lavender pests and diseases
1. Lavender leaf spot disease: The main control method is spraying Bordeaux mixture at 1:200 for 2-3 preventive treatments, or zineb at 500-800 times dilution. Red spider mite
2. Lavender red spider mite: Its control methods mainly include timely treatment of dead branches and fallen leaves, and cleaning the environment to destroy the living places of leaf mites; correct cultivation methods, reasonable crop rotation, and strengthened water and fertilizer management; protecting natural enemies, releasing natural enemies, and using insects to control insects. In addition, there are control methods: in the early stage of disease occurrence, evenly spray 0.26% matrine at 1000 times dilution. When it occurs over a large area, evenly spray 20% dicofol emulsifiable concentrate at 1000-2000 times dilution, or 1.8% abamectin emulsifiable concentrate at 3000-4000 times dilution, and the control effect is relatively good.
When planting lavender, you must understand its growth habits, and then choose a suitable time for planting. In the later stage of planting, management should be strengthened, especially in terms of fertilizer and water and pests and diseases. Only by doing these tasks well can lavender grow healthily.
