1. The sandy soil should be loose

It prefers to grow in a fatter sandy loam. In addition, when selecting the soil, we must pay attention to the looseness of the soil, and the drainage and air permeability are better. If the soil is not selected well, it will be bad for its roots. This is not conducive to its growth. In addition, when selecting soil, it will be better to mix some rotten leaves together

Half a month after the seedling is put into the pot or half a month after the old plant is separated, we can apply nitrogen fertilizer to it two to three times. Remember to use liquid fertilizer, so that it can promote the growth of its stems and leaves. After flowering, we can also apply fertilizer again, mainly liquid nitrogen fertilizer, which can make it more robust. But in summer, stop fertilizing. If you really want to apply it, apply a little compound fertilizer. In addition, when fertilizing, you can't put fertilizer on its leaves, otherwise its leaves will rot

3. Appropriate seed retention

If you keep seeds, you use the brain plant of chrysanthemum. Don't harvest it after summer, let it grow all the time, and add appropriate fertilizer, so that it can blossom and seed better. When the seed matures in December, it is necessary to cut off its flower head, then dry it, rub out the seed hard, and let the old plant stay in the field after planting. It can start to harvest its tender shoots and go on the market in March next year
