Chrysanthemum should be raised in the soil with high nutrient content and strong drainage capacity. Generally, it can be made up of saprophytic soil, sandy soil and fertilizer cake residue in the proportion of 6:3:1. After the preparation, you can add a little vinegar to reduce the pH value of the soil, making it more conducive to the growth of chrysanthemum
When watering chrysanthemums, you should see that they are dry and wet, not half dry and half wet. In addition, we should pay attention to the rainy season to timely remove the water in the soil, otherwise it will easily lead to rotten roots.
Chrysanthemum, as a typical short sunshine plant, does not need too long time of light to bloom. On the contrary, if the time of light is too long, it will only grow leaves but not flowers. In addition to the flowering period, other times of sun time can be slightly longer
Chrysanthemum likes to be cool and a little cold resistant. The suitable temperature for growth is 18-21 ℃, the highest temperature in summer can not be more than 32 ℃, and the lowest temperature in winter can not be less than 10 ℃. At the beginning of flowering, it should not be lower than 17 ℃, and the middle and late stages of flowering can be reduced to 15-13 ℃.
1. Change basin every year. After a year's cultivation, the soil in the chrysanthemum basin is basically depleted of nutrients. At this time, we need to replace it with a new basin soil with sufficient nutrients. The change of basin usually takes place in spring.
2. Trim in time. In order to reduce the consumption of nutrients, the lateral buds of chrysanthemum should be cut off. At the beginning of pregnancy, we should choose unnecessary flower buds to cut off, so as to increase the nutrient intake of the left flower buds and make the flowers bigger and more colorful.
