1. What is the planting method of cosmos?
Cosmos is generally planted by seeds, and the method is relatively simple, mainly in germination, sowing, daily management and so on. Let's take a look at the cultivation details of cosmos:
1, the illumination conditions of the universe
Cosmos likes sunshine, especially at seedling stage, and needs short sunshine every day to meet the number and color of subsequent flowers.
2. The growth temperature of the universe.
The optimum temperature for the growth of cosmos seeds is about 20-25℃. Too high or too low will affect the germination of seeds and may cause the phenomenon of non-germination.
3. The planting soil of the universe
Generally speaking, cultivating cosmos in the open field does not require much soil, but it is more suitable to choose sandy soil with good drainage and strong permeability for potted plants. Different from other plants, there is no need for sufficient base fertilizer here, because it may cause the white length of leaves and branches, thus affecting the quantity and quality of flowering.
4. Fertilization methods in the universe
Because cosmos doesn't need too fertile soil, ordinary organic fertilizer is more suitable for its growth. Plant ash and waste water are good fertilizers. Remember to apply too much fertilizer at a time, or you will burn your roots.
5. The watering method of the universe
Potted cosmos must be soaked in water, and of course it can also be watered thoroughly at one time before sowing. The whole seedling stage and growth stage can't be short of water, but it's not recommended to pour a big pot when watering, and the water should flow for a long time to avoid damaging its roots.
2. What is the quotation of cosmos seeds?
The price of cosmos seeds is different, because the characteristics of different varieties are different, so the price is different, which is basically kept at 20- 100 yuan a catty. The cheaper ones are generally tall varieties, and the more expensive ones may be varieties with improved colors. You can choose according to your own needs.
When buying cosmos seeds, we must distinguish between tall stems and short stems, because the needs of potted plants and open cultivation are different, and short stems are more suitable for potted plants. I suggest you choose a variety with beautiful plant shape, good flowering, strong disease resistance and strong adaptability. When sowing, you can accelerate germination, soak it in warm water in advance, then wrap it in a wet tissue and put it in the dark, and it will germinate in about a few days.
