Petunia blooms mostly in summer and can last until frost falls. It is about April to October, which is its natural flowering period. If some catalytic measures are taken, it can also bloom in winter. There are many kinds of colors, including white, red or purple, which has high ornamental value. After it blooms, the remaining flowers need to be trimmed off so that it can bloom twice

2、 Methods of promoting flowering

1. Water replenishment: during the breeding period, water replenishment should be carried out reasonably, and the slightly wet state should be maintained at all times. The cultivation soil should not be too dry or too wet. Especially before flowering, don't water too much

2. Fertilization: the plant will consume a lot of nutrients when flowering, so it should be fertilized once every ten days during its growth, and more phosphorus and potassium fertilizer can be applied during bud pregnancy

3. Pruning: when the planted seedlings grow to 10cm, it is necessary to pick the heart, which can promote flowering. After flowering, the remaining flowers should be trimmed off, which can also help the lateral branches grow and blossom better
