1. Adequate light: For any plant, light is helpful for flowering, and lavender is no exception.Ensuring sufficient light can make flower buds differentiate better, thus promoting plant flowering.If the environment is too dark, it will grow in vain, not only can not blossom, but also look very ugly.
2. Appropriate fertilization: Lavender flowering needs certain nutrients, so it should be properly fertilized.Fertilizers usually choose phosphorus and potassium fertilizers, which can promote flowering.In the process of growth, the amount of nitrogen fertilizer should be controlled, otherwise it will also affect the flowering of plants.
3. Appropriate temperature: Lavender will bud in the environment of 25-30 , and the plant will blossom when the temperature is between 20-22 .If the temperature is too low or too high, it is not conducive to flower opening.Therefore, water should be sprayed to cool down in high temperature areas, while appropriate heat preservation should be carried out in low temperature areas.
