Cosmos is very popular with people, but it is not easy to grow beautiful cosmos. Cosmos is a kind of flower plant that is not too difficult to grow, and there are many people who cultivate it. Today, Xiaobian will introduce to you how to plant the price of cosmos seeds.

How do you plant seeds?

1. Seed time of cosmos

When summer flowering is required, it should be sown in early spring from February to March, preferably under controlled temperature and humidity. If you plan to sow in the open air, you should sow in mid-April when the temperature is right. When the temperature is right, you can sprout in about a week.

The sowing medium should be loose and rich in organic matter, and a certain amount of decomposed organic fertilizer should be applied before sowing. When sowing, mix the seeds evenly with a certain amount of sand, and spread them evenly on the seedbed, covering the soil about one centimeter later. After sowing, the soil moisture should be maintained, and the temperature should be controlled at about 18℃ to germinate.

2. Management of cosmos at seedling stage

When the seedlings have grown 4 to 5 true leaves, they can be transplanted into a nutrient bowl and removed. Seedling growth period does not need to apply topdressing, so as not to cause excessive growth of branches and leaves, affecting flowering.

3. Management of cosmos growth period

Cosmos plant type is relatively tall, thin stem, large and beautiful flowers, wind or other bad weather will lodge, affecting the ornamental value. Therefore, cosmos throughout the growth process need to be removed many times, and reduce watering, this can not only promote branching, but also make the plant dwarf, avoid lodging phenomenon in the growth process.

4. Pest control

The main pest of cosmos is powdery mildew. Red spiders are easy to appear when it is hot and dry (whether you like it or not, cosmos has a high probability of red spiders, even if only two trees are planted, there may be red spiders). It should be discovered early and prevented early. Powdery mildew occurs on leaves, tender stems, flower buds and flower buds. There are gray-white powdery mildew layers on the diseased parts, which lead to the growth and development of the injured plants being hindered and the leaves being distorted. In severe cases, the leaves dry up and the whole plant dies.

The control method is as follows: when planting, the density should not be too large, and good ventilation and light transmittance should be maintained; after the disease occurs, the diseased leaves and diseased plants should be cut off and destroyed in time to prevent reinfection; at the initial stage of the disease, 1500 times of 15% triadimefon wettable powder or 1200 to 1500 times of 10% Lewubing wettable powder should be sprayed alternately, and the two drugs should be sprayed continuously for 2 to 3 times. At the initial stage of red spider occurrence, spray 40% dicofol EC 1000 to 1500 times.

The price of seeds.

The price of cosmos seeds is relatively cheap, dozens of yuan a catty, for people who do not need a lot of sowing, choose online shopping cosmos seeds is a good way. Because online shopping can choose the number of seeds needed, it can also be matched with different colors of cosmos seeds, so that the cosmos is colorful.

Cultivation method of cosmos

1. sowing

The seed of cosmos is the basis of its growth and reproduction. Sow cosmos seeds from April to June of each year without soaking before sowing, so that the germination rate is high. Sow 2 seeds every 20-30 cm, cover with soil after sowing, and the thickness is about 0.5 cm. The seed germination days of cosmos is 1 week. When cosmos grows to 4-6 leaves, the stem head is cut off, so that new buds and flowers can be issued next to it. Do not fertilize ground and pot plants unless the growing conditions are extremely harsh.

2. growth

Cosmos prefers warm and cool climates, and cosmos seeds grow best in sunny environments. Therefore, the flowerpot should be placed in a place with sufficient light for maintenance, watering should also be watered with a multi-eye watering can, not irrigation, so as to avoid rushing out of the newly germinated seedlings. Watering times should not be too much, keep the soil moist.

3. management

The stem of cosmos is relatively thin and easy to lodge, so families can build supports when playing cosmos seeds, and can also pick the heart many times in late spring and early autumn to promote the germination of more and more branches, and also inhibit its growth height to keep it straight. The seed growth period of cosmos needs to control fertilizer and water, and the soil is moist, which can make cosmos flowers flourish. If the fertilizer and water are properly controlled, flowers can be seen in 12 weeks.

4. cycle

After the flowers and fruits are ripe, the cosmos plant will die, and the cosmos seeds will automatically fall from the plant and be sown in the soil to continue life. Of course, when the fruit is ripe, the seeds of cosmos can be picked down and re-sown the following year. You can also select a thick top branch cut a section for insertion propagation, inserted in the flowerpot.

When is the best time to plant seeds?

Cosmos often uses the method of sowing reproduction, April spring sowing, germination quickly, 7-10 days after sowing germination. It can also be propagated by young shoots, and roots are born 15-18 years after insertion.

In late March and early April, seeds are sown in open seedbeds. Germination can occur even at a relatively low ground temperature of 15 ° C, but if sown early, it will grow into a giant plant 2m high, and it will easily lodge due to typhoons or plant weight. There are also early-blooming varieties that bloom 50 to 70 days after sowing, so they should be sown early and autumn.

Cosmia can also be sown in September to October, which is autumn sowing.
