1. Trim properly

When the main stem of Gardenia grows to about 20 cm high, it should be topped in time, leaving only three or four branches to concentrate nutrition as much as possible. This can promote branching and make the plant shape fuller after growing. And cut off the branches that grow too fast and too dense at any time. After the flowers wither every year, the sick and weak branches should be cut off and the long branches should be cut off. It should be noted that the top of branches cannot be shortened in spring, otherwise it will be difficult to bloom in that year

2. Suitable light

Appropriate light can make the plant synthesize sufficient nutrients and make its own trunk grow taller and thicker. To ensure that plants have 60% of the day's light every day, especially in the morning and evening, let them see more sunshine, but pay attention to avoid strong light

3. Soil suitability

The soil for Gardenia cultivation is also very important. The soil must be loose, fertile and nutrient rich weak acid soil, which is conducive to the plant to absorb nutrients and promote its own growth. It can be prepared with rotten leaf soil and mixed with some rotten organic fertilizer to improve the nutrient content in the soil

4. Timely fertilization

Gardenia likes to be fat, which makes it grow tall and thick. It is inseparable from adequate nutrient supply. During planting, some rotten cake fertilizer can be applied as base fertilizer. In its growth period, you can apply a little more nitrogen fertilizer, but you can't only apply nitrogen fertilizer, otherwise it will grow in vain. We should also apply some phosphorus and potassium fertilizer according to its growth to ensure the balance of nutrient elements

5. Suitable moisture

Gardenia likes humidity. When you see that the basin soil is dry, you should supplement water in time, and spray water on the branches and leaves of the plant to improve the humidity of the surrounding environment, so that the plant has enough water supply to make it grow strong
