How to Plant Lavender
As a representative of aromatic therapeutic plants, lavender cultivation has become a new favorite of gardening enthusiasts. This mysterious flower from the Mediterranean requires mastery of six key stages from seeding to blooming. This article will systematically analyze the entire process of lavender cultivation, helping you create a purple aromatic herb garden.
One, Choosing the Planting Time
1.1 Best Sowing Season
Lavender seed germination requires a temperature of 15-30℃, it is recommended to sow in spring (March-April) or autumn (September-October) in the Yangtze River Valley. For cold northern regions, early spring sowing in a greenhouse is suitable, while for high-temperature southern regions, it can be postponed to the end of October.
1.2 Climate Adaptation Strategy
In summer, a 50% shading net should be set up for planting, and in winter, the night temperature should be maintained above 8℃. Annual production can be achieved through temperature control, but it is necessary to keep the day and night temperature difference at 5-8℃.
Two, Seed Treatment Technology
2.1 Scientific Germination Method
Adopt a gradient soaking method: first soak the seeds in 40℃ warm water for 2 hours, then transfer to 30℃ clear water for 24 hours. Keep the humidity at 80% when using a wet towel to promote germination, and ventilate for 30 minutes every day to prevent mildew.
2.2 New Dormancy-breaking Technology
It is recommended to soak the seeds in a gibberellin solution (concentration 50mg/L) for 4 hours, which can increase the germination rate to 85%. After treatment, the time for the seeds to show white is reduced to 3-5 days.
Three, Cultivation Substrate Formula
3.1 Soil Golden Ratio
Professional formula: Perlite 30% + Decomposed Leaf Soil 40% + Vermiculite 20% + Rice Husk Charcoal 10%. Add 500g of bone meal and 200g of superphosphate per cubic meter as a base fertilizer.
3.2 Container Selection Points
It is recommended to use a ceramic pot with a diameter of more than 25cm, and set a 3cm layer of碎石 for drainage at the bottom. For ground planting, raise the ridge to 30cm high and maintain a row spacing of 40-50cm.
Four, Planting and Maintenance Management
4.1 Seed Depth Control
Use a thin covering soil technique: cover with 2-3mm fine sand after sowing, gently press with a board to ensure the seeds adhere to the soil. Use the immersion pot method to supply water, keeping the surface slightly moist.
4.2 Light Control Scheme
Maintain a light intensity of 5000-8000lux during the seedling stage, and more than 30000lux during the mature plant stage. When using a shading net, ensure at least 4 hours of direct sunlight every day.
Mastering these four core elements, it only takes 120 days from seeds to inflorescences. Regularly pruning the残花 and maintaining a soil pH of 7.0-8.3 will ensure your lavender blooms year after year. It is recommended to plant with rosemary and sage to create a synergistic aromatic herb ecosystem.
