Family culture methods and matters needing attention of Persian chrysanthemum

The universe is a very famous ornamental flower. It comes from Mexico America. However, it is now widely cultivated in China. It can grow on the side of the road, fields or river banks, but now it is the family. Breeding methods, the following small series for everyone to introduce the universe family breeding methods and precautions, I hope you like.

Cosmic culture.

lighting

Cosmos is strong and sunny and can be used for short days. It should be pointed out that the universe does not demand much from soil. If it is transplanted into fertile soil and the light is not strong, the plant grows easily.

water and fertilizer management

Water: The universe is like water. During drought periods, it can be watered 2-3 times a day, once every 1-2 days. But avoid basin water.

Fertilization: If base fertilizer is applied in the upper pot, no fertilization is required for the growing season. If the soil is too fat, the leaves grow easily and flowering is reduced. Or water was applied to decomposed urine 5 times every 10 days during growth.

breeding methods

Sowing: The sowing of the universe takes place from March to April. When seedlings have 4 - 5 true leaves, they can be transplanted and topped.

Cuttings: summer, cuttings are cut, survival rate is very high. In May, you can select a sturdy top branch, cut slices 8 cm to 10 cm in length, and insert 3 to 5 strains into a pot. Pots should be buried in the soil to expose the ground. 4 cm to 5 cm, watered and shaded, rooting half a month later. After rooting, fertilize every 15 days, and when 15 cm long, remove terminal buds to promote multiple shoots. If fertilizer is properly controlled, flowers will be visible in about 45 days.

Cosmic domestic considerations

anti-falling

Cosmic plants are tall and easily swayed in the wind, but they are also easily destroyed by the wind.

If you want to plant a short and not fallen universe, you should delay sowing until July, or pick up the heart when the plant grows to 40-50 cm in spring, so that the axillary buds will bloom.

prevent pests and diseases

The main diseases of the universe are leaf spot disease and powdery mildew, which can be sprayed 500 times with 50% Tofu WP.

Cosmic attention pests are aphids, chafers, etc., can be sprayed 2% of the insecticide cream 2500 times. It is easy to cause red spider damage when it is hot and should be prevented as soon as possible.

Universe prevents boarding

To prevent the universe from falling, you can do three things.

Select the sowing time. The seeding of the universe can take place in July and August. Since the universe is a short-day plant, spring-sown seedlings are thriving, but flowering less, and plants usually grow taller and tend to fall. But in July and August summer seedlings, plants short and regular, flowering. Because sowing at this time, sufficient light, high temperature, so the growth will be faster, plant type will not be very high, flowering will also be in October, so it is not easy to cause lodging.

Dwarf plants. Dwarfing cosmic plants is also the main way to prevent lodging. First, dwarfing gets better because plants in the universe are very tall; second, improper protection during growth can lead to plants lengthening and dwarfing. Reduce fertilization and avoid its length during the growth of the universe. During the whole growing season, it can also be watered many times, so that the plants are constantly dwarfed and the plants are not easy to fall down. This constant topping also allows the universe to open up more words.

Set up the bracket. When the cosmic plant grows to a certain height, the support can play a supporting role, especially in the windy position, to avoid lodging and breaking.
