How to cultivate and manage potted chrysanthemum? These six measures are indispensable.

Chrysanthemum is a perennial perennial root sub-shrub. Because of its wide variety, the leaf shape, flower pattern and flower color change greatly. So, how to cultivate and manage potted chrysanthemum? In order to make large flowers, beautiful color, green leaves, moderate height, symmetrical posture, the next six measures are indispensable.

First, the appropriate period to control fertilizer, chrysanthemum like fertilizer, if improper fertilization is easy to cause overgrowth, excessive fertilization, then the plant height and leaves are sparse, so the base fertilizer should be based on phosphorus and potassium fertilizer. Topdressing should not be applied too early. If the leaves are small and thin and the leaves are yellowing, 0.1% urea water can be sprayed many times until they turn green. If there are symptoms such as phosphorus deficiency and potash fertilizer, 0.2% potassium dihydrogen phosphate solution should be sprayed. After the Beginning of Autumn to before flowering, fertilizer and water should be sufficient, its concentration should be gradually increased, and attention should be paid to the application of phosphorus and potassium fertilizer, which can make the flower color positive and the florescence long.

Second, water control is the only effective measure to make chrysanthemums grow sturdy, dense, fertilized leaves and not barefoot. Potted chrysanthemum should be watered in a timely and appropriate amount, and even in the peak growth period, the daily amount of water should only be maintained until the amount of water needed to evaporate at noon during the day, that is, spraying foliar water to the leaves every morning and evening.

Third, change the soil in the right pot. In the whole growth process of chrysanthemum, it is generally necessary to change the pot for 3 times. Transplanting in a small basin with a diameter of about 12 cm at the seedling stage, culturing in a basin with a diameter of about 15 cm at the strong seedling stage, and culturing in a pot with a diameter of about 20 cm before bud differentiation, fertilizer should be added timely, only in this way, the flowerpot gradually increases and the pot soil increases gradually, which is conducive to providing the right amount of water and fertilizer needed for all stages of growth and development. Do not raise small seedlings in large pots or big seedlings in small pots. If it is found that the branches and leaves are too abundant, part of the resident soil or fibrous roots can be removed.

Fourth, picking the heart in time can promote the lateral branches and effectively depress the plant height. The coring time and times of potted plants vary according to different art of shape selection. Generally, 7 flowers are left. After planting, chrysanthemum seedlings are left with 5 leaves. When the lateral branches grow 5 leaves, each side branch leaves 3 leaves for the second coring.

Fifth, wipe buds and sparse buds, chrysanthemum strong seedling stage, sprouting a lot of axillary buds, need to be pinched off with fingers in time, otherwise consume a lot of nutrients, and can send out a lot of lateral branches, making the plant appear disorganized. During the bud period, side buds sometimes appear on the branchlets under the apical buds. In addition to those that need to be retained, they should also be removed as soon as possible to promote the hypertrophy of the parietal buds.

Sixth, raise foot leaves well, as the saying goes, "flowers still need green leaves." During the growth of potted chrysanthemum, reasonable fertilization, watering and prevention of diseases and insect pests can not only prevent foot leaves from withering and falling off, but also ensure that the leaves are green and beautiful, and improve the ornamental effect.
