When is the best time to cut chrysanthemums (when and how to cut chrysanthemums)

Chrysanthemum, also known as Shouke, Jinying, Huanghua, Qiuju and Hermit Flower, is a perennial herb of Chrysanthemum in Compositae. Chrysanthemum has been cultivated in China for more than 3,000 years, and it is also called "four gentlemen in flowers" with plum, orchid and bamboo. People in China have the custom of enjoying chrysanthemums and drinking chrysanthemum wine on the Double Ninth Festival. To this end, Meng Haoran, a poet in the Tang Dynasty, wrote in his poem "Passing the Old People's Village" that "I'll come back when I'm in the chrysanthemum during the mountain holiday". The planting season and maintenance methods of chrysanthemum seedlings are introduced below.

First, the planting season

The best time to plant chrysanthemum seedlings is from March to April in spring, when the climate is warm and humid, which is the growing season of chrysanthemum, which can improve the survival rate of chrysanthemum seedlings and promote their growth and development, or 9- 10 in autumn.

Second, the maintenance method

1. Potted soil

Because of the rapid growth and development of chrysanthemum seedlings, the pots should be changed two or three times before the pots are fixed in July, and the small pots should be used first and then the large ones. The soil should be sandy soil with good drainage, loose air permeability and high fertility, and compost soil can be mixed with humus soil, sandy soil and cake fertilizer residue in the ratio of 6:3: 1.

water

Chrysanthemum seedlings are tender in spring, so water them less. In summer, the seedlings grow up, the climate is hot and the water evaporates quickly. Water should be poured once in the morning and once in the evening to ensure sufficient water. When the environment is dry, water should be sprayed on the chrysanthemum and its surroundings to improve the air humidity. Water should be controlled before flowering in autumn to prevent chrysanthemum branches and leaves from growing too fast, which will lead to weak flower potential. After flowering, the amount of watering can be increased. In winter, chrysanthemum grows slowly and needs less water, so it needs less watering and maintenance.

fertilize the soil or land

In July, when placing chrysanthemum pots, base fertilizer should be applied in the pots. After applying base fertilizer, apply nitrogen fertilizer every 10 day, and apply phosphorus fertilizer or potassium fertilizer before chrysanthemum blossoms in autumn, which can make the flowers bloom more and more brightly, and stop applying fertilizer after flowering.

prune

When the chrysanthemum grows to 10 cm, it is necessary to start removing the core, removing all the upper leaves and leaving 4-5 leaves at the base. When the chrysanthemum grows 5-6 new leaves again, it needs to be pitted again, and 4-7 main branches are reserved. When the chrysanthemum grows more new leaves, it is necessary to go to the core for the last time. When removing the core, the chrysanthemum should be trimmed, and the weak branches, clustered branches and dense branches should be cut off, and 3-5 branches should be kept.
