1、 What if it doesn't bloom

1. Add sunshine: cloves can't bloom without the action of sunshine. If they haven't seen sunshine for a long time, it will be difficult to bloom naturally. They can be moved to the sun for maintenance and used to breed flower buds through light cooperation

2. Proper watering: Although lilac is relatively drought resistant, it cannot be used without water, which will lead to weak growth and unable to breed flowers. If the soil inside is found to be dry, water it in time, and water it appropriately during the growth period to supplement water

3. Rational fertilization: the opening of flowers needs to consume a lot of nutrients. If fertilization is not timely, it will not bloom without nutrient supply. If it is found that there is a lack of fertilizer, it needs to be fertilized in time, and it is also necessary to do a good job in fertilizer and water management at ordinary times

4. Treatment of diseases and pests: if you don't pay attention to the maintenance methods during the maintenance process, the plant may be infected with diseases and pests, thus affecting the flowering. You need to cut off the branches infected with diseases and pests, and then spray chemicals accordingly

2、 How long is the flowering period

Under normal circumstances, the flowering period of lilac is about two months, but there is a kind of four-season lilac with a long flowering period, which may last for four or five months from May to October
