Lavender is suitable for growing in warm environment, so it is planted mostly in spring and autumn.In summer, the temperature is too high, strong light is easy to make seedlings suffer from sunburn, and in winter, it is too cold, low temperature inhibits seed development.If you want to plant in these two seasons, you must control the temperature, if the temperature is between 15-30 C, you can grow normally after planting.
In order to ensure that lavender seeds can germinate, it is usually necessary to accelerate germination before sowing.Soak the seeds in clean water. After 1-2 days, take them out and put them on a wet paper towel. Cover them with plastic wrap and poke a few small holes on them for ventilation.Put it in a cool place and wait for it to take root. When it grows white roots, you can sow it.If the seeds are not germinated, it may take a month for them to take root and germinate.
Lavender is suitable for growing in loose and fertile sandy loam. It can be prepared with garden soil, peat and sandy soil, and mixed evenly according to the ratio of 5:3:2.In addition, a proper amount of base fertilizer can be added to provide nutrients for plant growth.It is not suitable to plant in too sticky soil, otherwise it will affect the respiration of roots.
Spread large granular substrate at the bottom of the flowerpot, then fill the prepared soil into it, put the seeds in the middle, and cover them with fine soil.After planting, we should water a little to keep the humidity of the environment.At the same time, avoid receiving light to prevent water loss too fast.When it grows true leaves, it can see light properly and supplement fertilizer.
