How can potted chrysanthemums blossom more? How to prevent the occurrence of rust?

Chrysanthemum is a very famous ornamental flower with many varieties and is planted all over the world. Chrysanthemums can not only be planted in the open field, but also can be potted in the courtyard, which means auspiciousness and longevity. Let's learn about how potted chrysanthemums can blossom more. How to prevent the occurrence of rust?

First, how can potted chrysanthemums bloom more?

1. Key points of fertilization

Because in the period of time when the chrysanthemum blossoms, the amount of fertilizer it needs is relatively large, usually in the peak season of its growth, if the fertility does not keep up, then there will be yellow leaves or even plants stop growing.

When it is ready to bloom, if the fertilizer does not keep up with it, then its bud will be reduced accordingly, and the flower head will become smaller and the number of flowers will be reduced accordingly.

If you want to apply fertilizer to it, try to apply a mixture of nitrogen, phosphorus and potassium. For example, for nitrogen fertilizer, we can use soybean water, phosphate fertilizer, bone powder, and potash fertilizer, we can use water and fertilizer made from fruit peel.

2. Pay attention to the protection of diseases and insect pests

Usually when watering flowers, you can add some cut tobacco water or garlic water, pepper water and so on, so that it can be used to irrigate chrysanthemums, which will make the plant produce antibodies and avoid being hurt by aphids.

If it is particularly serious, cut off and throw away the branches that attract more insects to avoid infecting other healthy branches, and then wash the remaining sporadic aphids.

3. Lighting

Potted chrysanthemums should be kept in a sunny position as far as possible, so as to keep the flowers blooming. Potted chrysanthemums bought by some friends have been kept indoors for a long time. Although there are many buds, they lack light, and the buds cannot open normally. The buds will continue to fall and rot.

The best place to maintain potted chrysanthemums is to have about 5 to 6 hours of direct light every day, give more light in the morning, and properly shade in the summer afternoon to avoid too strong light and sunburn flowers and leaves.

Second, how to prevent and control rust in potted plants?

Chrysanthemum rust mainly harms leaves and stems, light yellow spots can be seen on the leaves at the beginning, small chlorotic spots are also produced at the back of the leaves, and then slightly raised blister is produced. After the blister is broken, a large number of yellowish-brown powdery matter are scattered. The growth of chrysanthemum is very weak after being infected, and it does not blossom or fall in large numbers. If there are many disease spots on the leaves, the edge of the leaves will roll up, and a large number of them will die.

1. Potted chrysanthemums should dredge the drainage holes or holes at the bottom of the pot to prevent stagnant water in the basin. When planting, the basin soil should choose the sandy soil with fertile and good drainage. Properly increase the application of phosphorus and potassium fertilizer to improve disease resistance.

two。 Immediately after the disease, the diseased leaves were removed, the seriously diseased plants were removed, and the treatment was concentrated on deep burial in order to control the spread and spread.

3. Chemical control. At the initial stage of the disease, sprayed with Bordeaux solution of 1RV and 200V, or 500x solution of 65% Dysen zinc, or 0.3-0.5C solution of stone-sulfur mixture, or 1000-1500 times liquid of 15% trimethoprim wettable powder, sprayed every 10-15 days, 2-3 times in a row.
