Management method of potted chrysanthemum in courtyard in September

1. water

When watering potted plants, you should loosen the soil for the plants once every half month.

fertilize the soil or land

September is the period when most flowers grow vigorously. Some flower seeds that are dormant and semi-dormant in summer begin to grow again with the gradual cooling of the temperature. Therefore, we should attach great importance to fertilization management this month.
