Chrysanthemum cultivation methods and precautions

1. Soil

To grow chrysanthemums, you need soil with high nutrient content and strong drainage ability. Generally, you can mix leaf mold, sandy soil and fertilizer cake residue in a ratio of 6:3:1. After preparation, you can add a little vinegar to lower the pH value of the soil, making it more conducive to the growth of chrysanthemums.

2. Water

When watering chrysanthemums, water them when the soil is dry and then wet, not half dry and half wet. In addition, it is important to drain the accumulated water in the soil in time during the rainy season, otherwise it will easily cause root rot.

3. Lighting

As a typical short-day plant, chrysanthemum does not need too much light to bloom. On the contrary, if the light time is too long, it will only grow leaves but not bloom. Except for the flowering period, the time for sun exposure can be slightly longer at other times.

4. Temperature

Chrysanthemum likes coolness and is slightly cold-resistant. The suitable temperature for its growth is 18-21℃. The highest temperature in summer cannot exceed 32℃, and the lowest temperature in winter cannot be lower than 10℃. The temperature should not be lower than 17℃ when it just starts to bloom, and it can drop to 15-13℃ in the middle and late stages of the flowering period.

5. Notes

1. Change the pot every year. After one year of growth, the nutrients in the soil in the chrysanthemum pot are basically consumed. At this time, you should replace it with new potting soil with sufficient nutrients. Repotting is usually done in spring.

2. Prune in time. During the chrysanthemum seedling stage, the side buds need to be cut off to reduce nutrient consumption. When the buds first begin to form, you should choose to cut off the unnecessary buds to increase the amount of nutrients available to the remaining buds, making the flowers that bloom larger and brighter.
