1、 Avoid moisture

When lavender blooms, the maintenance environment should not be too wet. It is necessary to create a dry and cool environment for it. Therefore, the amount of watering must be well controlled during the flowering period. It is best to decide according to the dry humidity of the culture soil, and replenish water after the soil is dry

2、 Lower the temperature

Lavender has good heat resistance, but in the environment of 15-25 ℃, it can make plants bloom better and more. However, the temperature in summer will be higher than usual. If the temperature is too high, it is likely to lead to less flowers or no flowering. If the temperature has reached 30 ℃ or 35 ℃, cooling methods shall be made

3、 Increase fertilizer application

During its flowering period, it should be supplemented with fertilizer. It is recommended to use special flower fertilizer. It must be diluted with water before it can be used, otherwise the fertilizer concentration is too high and the root will be burned. At this time, phosphorus and potassium fertilizer is mainly applied to help it bloom. Do not apply nitrogen fertilizer, which is easy to cause plants to grow in vain without flowering

4、 Trim properly

Even in its flowering period, it should be properly trimmed, usually cutting off the branches that are in poor growth and do not bloom, because these branches will consume the nutrients in the pot soil and hinder its flowering
