1、 Flowering time

Lavender usually blooms in summer, and the flowering period is from June to August. If the temperature is appropriate, the flowers will bloom in May. The full bloom period is from June to July. The flowers are basically withered in September, and only a small part can last until October. It usually blooms in the year of planting, and it usually takes 18-20 weeks from sowing to flowering

2、 How to grow flowers

1. Increase light: the growth of lavender cannot be separated from sufficient light. The longer the light time is, the more helpful it is to the differentiation of flower buds. At the same time, it can make it better carry out photosynthesis, so as to accumulate more nutrients. It usually needs to be planted in a sunny place. Indoor potted plants can be placed on the balcony so that it can receive light

2. Temperature control: lavender is suitable for growing in a warm environment. It grows well at the temperature of 15-25 ℃. If the temperature is too high, it will lead to withered and yellow leaves, and if the temperature is too low, it will make it dormant. Generally, it should be placed in a warm place, especially after the emergence of flower buds, which can also promote flowering

3. Reduce watering: Lavender itself does not have a high demand for water. If it is watered more, it will affect its growth. Although the environment with sufficient water is conducive to plant development, it is not conducive to flowering. If you want it to transfer nutrients from growth to flowering, you need to control watering and prolong the watering interval

4. Supplementary fertilizer: any plant needs certain nutrients for flowering, and lavender is no exception. Appropriate fertilization can promote flowering before flowering. Phosphorus and potassium fertilizer are often used as general fertilizer. If nitrogen fertilizer is applied, it will lead to plant overgrowth and inhibit plant flowering
