When will the chrysanthemums top in September?

Generally, cuttings are cut in April-May, or the plants are divided into pots. First, the seedlings are placed in a small pot, and the core is picked once every 10 days after the pot is placed, and then topping is carried out once every other month. The last topping is carried out around beginning of autumn. Only 2-3 buds are left when topping, not too many, and 2-3 times are added during the vegetative growth period of the seedlings.
