1、 Soil requirements

It is easier to cultivate perennial chrysanthemum than other compositae plants, because it has nothing to do with the soil. It can be cultivated in the soil with appropriate light and temperature and large gap

2、 Cultivation process

1. Phase I

The first stage of field planting is to sow the seeds into the soil until they sprout. Because seed germination requires sunlight, there is no need to use sunshades and other things at this stage. In addition, it is also necessary to keep a certain amount of water in the soil, that is, neither too much water nor too little water, which is conducive to seed germination

2. Phase II

After germination to grow real leaves is the second stage of ground planting. At this time, the planting temperature should be appropriately reduced, preferably maintained at about 18 degrees to 20 degrees. At the same time, at this stage, the soil humidity should also decrease, but it should not be too dry. p>

3. Phase III

The third stage of cultivation is that the true leaves begin to grow normally and grow more and more true leaves. At this stage, the humidity of the air needs to be reduced slowly. The watering time separated by two times can make the soil from smooth to dry, which is good for the growth of its roots

4. Phase IV

The roots of perennial chrysanthemum are basically stable and well developed, and can be transplanted as the fourth stage of ground planting. The air and soil requirements at this time are roughly the same as those in the previous stage

3、 Fertilization

Perennial chrysanthemum doesn't like fertilizer, so it can be properly applied with a thin layer of fertilizer about 12 days after it is loaded into the pot, and then applied once a month and a half later. And add a kind of room corrosion fertilizer into the soil as an additional fertilizer before moving to outdoor planting. Irrigation is to apply a kind of fertilizer to prevent the fertilizer from being diluted, about twice in total. In the flowering period, additional fertilizer should be applied to prevent the loss of magnesium, iron and other substances
