It needs a place with sufficient light and good ventilation. Yu Meimei doesn't have strict requirements for soil, but it's better to use loose and fertile sandy loam.
In January, use a flowerpot with an inner diameter of 20cm to fill half of the basin with loose soil, flatten it, then sow, 20 to 30 seeds, and then cover the soil until the seeds can not be seen. after sowing, the method of soaking in pot and soaking in water is to put the flowerpot into a large pot with the water surface not higher than the height of the flowerpot, and let the water evenly penetrate into the soil from the hole at the bottom of the flowerpot.
When the seedlings are unearthed, remove the ones that do not grow well, and leave only 3 to 5 plants at last. when the seedling height is 30cm, gradually fill the planting soil to the edge of the flowerpot to prevent the plant stem from lodging.
Keep sufficient light, fresh air, no less than 5 ℃ at night to avoid drought and waterlogging. Depending on the weather and soil conditions, potted plants are watered once every 3-5 days in general. keep in this state, and flowers will bloom in March until May.
When the seedlings planted in the field are unearthed, remove the ones that are not growing well, and carry out seedling thinning according to the distance of 30 * 30. Because it is not easy for Yumei to raise them after transplanting, we must pay attention to the seedling thinning.
Before flowering, it can be properly applied 2-3 times of thin liquid fertilizer, but the fertilization should not be too much, which will easily cause diseases and insect pests. The soil was planted with two times of thin fertilizer before overwintering and another time of liquid fertilizer before flowering. The last application of topdressing before flowering can promote the flower to be bright and open.
In general, it is not necessary to water the soil frequently.
Maintain the temperature about 20 ℃, and sprout in 7-10 days. If there are diseases and insect pests, it is necessary to treat them in time, pay attention to hygiene, cut off the dried stems of the flowers in time, which can prolong the flowering period and make the flowers more beautiful.
It is not suitable to plant on the over fertilized soil, and it is not suitable to plant repeatedly.
It is not suitable to grow seedlings and plants in low-lying, humid, watery and light poor places, otherwise, the growth is poor and diseases are easy to occur.
Water less in winter and more in spring.
During the growth period of seedlings, watering should not be too much, but should be kept moist.
