1, plastic pruning, after flowering, you can carry out appropriate pruning, but pay attention to pruning time not at noon, but in the morning or evening, so as not to affect its normal growth. When pruning, cut off the residual flowers, dead branches and redundant side branches on the plants to prevent them from consuming a lot of nutrients. After pruning, more and more beautiful flowers will bloom in the second year.

2, reduce watering, lily will become very fragile after flowering, so you can't water immediately after pruning, you must reduce the amount of watering, because after flowering, it will slowly enter a dormant state, and no longer absorb water at this time. If there is too much water in the basin, the root will rot, so its growth will be limited and in severe cases it will die. So be sure to control the amount of water.

3. Fertilization and topdressing. Fertilization and topdressing must be done correctly after flowering.
