Lavender is generally planted in spring. Although the adult plants of this plant have a certain tolerance to high and low temperatures, the seeds and seedlings still prefer a warm climate.If the temperature is below 8 C, the seeds will be difficult to germinate.High temperature and strong light are easy to sunburn seedlings, which is not conducive to their subsequent growth, so they are seldom planted in winter and summer.
The seeds of lavender are relatively small and usually need to be germinated before planting.There are many ways to hasten germination, commonly used is paper towel hastening germination method.Prepare a container and paper towels, sterilize them with boiling water, wait until the water temperature drops, put the seeds on them, and cover them with a plastic film.In order to ensure air permeability, you can prick a few holes in the film, which will soon sprout.
Lavender is suitable for growing in loose and fertile soil. Therefore, garden soil and river sand should be used to prepare potting soil. If conditions permit, a little peat soil can be added. This is a very good substrate.In order to avoid pathogens or insect eggs in the soil, the substrate can be laid flat to the sun for drying, and then collected and put into pots.
Place the germinated lavender seeds on the surface of the soil and cover them with a layer of fine soil.After sowing, it should be watered thoroughly to ensure the moisture of the soil in the early stage.Put the flowerpot in a semi-shady place to avoid sunshine, so as not to be harmful to plant development.When the seedlings grow, they can be properly supplemented with water and a little nitrogen fertilizer.
