How to raise daisies?

Daisies, also known as spring chrysanthemum, Malan head flower, longevity chrysanthemum, etc., are perennial herbs of Compositae, native to Europe. Garden cultivation in various parts of our country, as ornamental plants in flower beds, blossoms in early spring, the flowers are petite and exquisite, the colors are harmonious, and they are full of vitality. with a gentleman's demeanor and innocent elegant demeanor, let's take a look at how to raise daisies!

Growth habits of daisies

Daisies like cool climate and avoid hot. Like light, but also resistant to semi-shade, the cultivation of soil requirements are not strict. The optimum temperature for seed germination and growth was 22-28 ℃ and 20-25 ℃ respectively. It is suitable for planting single or semidouble varieties of medium and small flowers in southwest China. The double petal varieties of medium and large flowers grow weakly and seed poorly.

How do daisies reproduce?

1. Seed propagation: in the south, most of the seeds are sown from August to September in autumn, or in spring, but they often grow poorly in summer. In the north, most of the seeds are sown in spring or in autumn, but the flower seedlings need to be transferred to the greenhouse for cultivation and management in winter. Because the seeds of daisies are relatively small, they are usually sown. However, sowing seedlings often can not maintain the characteristics of the mother plant.

2. Split-plant propagation: the variation of daisy seedlings is large, and the split-plant method can be used for some excellent varieties, but the growth potential is not as good as that of seedlings, and the fruiting is poor. In the middle and late March, the old stubble chrysanthemum cauliflower can be dug out to expose the root neck, and the lateral buds of the existing roots together with the old roots can be cut off and transplanted to the field. Ramet propagation is more suitable for sprouting new shoots.

3. Cutting propagation: daisies can be propagated by cutting in the whole growing season, and the survival rate of cutting from April to June is the highest. It is best to mix fresh soil with rotten organic fertilizer, cut the branches with 3-5 nodes and 8-10 cm long, remove the basal leaves, and dig into the soil at the depth of 1 inch, 1 inch, 2 cuttings. Keep the work bed moist and avoid waterlogging after cutting. shade is needed in high temperature season, and plastic film arch shed can be built to keep warm and moist when the temperature is low.

How to cultivate daisies?

The main results are as follows: 1. Transplant into the pot: the seedlings can be put into the pot after refining seedlings. At this time, the seedling already has three pairs of true leaves. If the seedling is raised with a hole plate, the root system is already full of the hole plate. 300px caliber nutrition bowls are often used in the upper basin. You don't have to change the basin after you put it on. Compound fertilizer can be added to the basin as base fertilizer. Pour root water in time after putting on the basin. Light regulation: daisies also like sunlight, including during the growing and flowering periods. Sufficient light can promote plant growth, green leaves and increase the number of flowers.

2. Temperature control: the pot can be moved to the protected area to survive the winter, which can prevent the potted flowers from freezing injury in winter. Daisies can survive the winter safely above 5 ℃, and keeping the temperature of 18-22 ℃ is the most suitable for the formation of good plants. In practice, it is very difficult to do so. Daisies can bloom normally at 10-25 ℃. When the temperature is lower than 10 ℃, the growth is relatively slow, the plant shape decreases, and the flowering is delayed. If the temperature is higher than 25 ℃, the flower stem will elongate, and the growth potential and flowering will decline. From May to June, the temperature rises, and the growth potential and flowering are not ideal, so autumn seedlings are generally used to avoid the rising temperature environment after May.

3. Water and fertilizer management: daisies like fertile soil, and the base fertilizer in its medium alone can not meet its growth needs. Therefore, topdressing fertilizer every 7-10 days, flower fertilizer can be used, compound fertilizer can also be used for point application or soluble water irrigation, and the concentration is 200~250ppm. But the effect of compound fertilizer application is not as fast as that of irrigation. Therefore, conditional water-soluble flower fertilizer can be used alternately. However, the amount of flower fertilizer should be reduced in winter, and the medium should be slightly dry, moist but not moist before watering. Because of its clustered basal leaves, if not ventilated, the basal leaves are easy to rot and infect bacteria. Sufficient water and fertilizer are given in the growing season to grow luxuriantly and prolong the flowering period.
