Lavender generally blooms in the summer, from June to August.If the temperature is suitable, there will be flowers in May, June-July is the peak flowering period, September flowers are basically withered, only a few can last until October.It usually blooms the same year it is planted, and it usually takes 18-20 weeks from sowing to flowering.
1. Increase illumination: The growth of lavender cannot be separated from sufficient illumination. The longer the illumination time is, the more helpful it is to the differentiation of flower buds. At the same time, it can better carry out photosynthesis so as to accumulate more nutrients.Usually need to plant it in the sunny place, indoor potted plants can be put on the balcony, so that it can receive light.
2. Temperature control: Lavender grows well in a warm environment at a temperature of 15-25 . If the temperature is too high, the leaves will wither and turn yellow. If the temperature is too low, the leaves will go dormant.Generally, it should be placed in a warm place, especially after the bud appears, which can also promote the effect of flowering.
3, reduce watering: lavender itself on the water demand is not high, if too much water will affect the growth.Adequate water environment is conducive to plant development, but not conducive to flowering, want to let it transfer nutrients from growth to flowering, need to control watering, extend the interval of watering.
4. Supplemental fertilizer: Any plant needs certain nutrients to blossom, lavender is no exception, and before flowering, proper fertilization can play a role in promoting flowering.General fertilizer more phosphorus and potassium fertilizer, if it is nitrogen fertilizer, it will lead to plant growth, but also inhibit plant flowering.
