When planting and changing pots, appropriate cake fertilizer or bone meal can be added to the soil as base fertilizer. Organic liquid fertilizer can be used in the growth period, and it can be used after dilution, about one month 1 time. Flower buds will grow in spring. Potassium dihydrogen phosphate fertilizer, which is mainly composed of phosphorus and potassium, can be used about 1 time every week, which can promote flower bud differentiation until flower buds form and stop fertilization. No fertilizer is applied at flowering stage, and 1 potassium dihydrogen phosphate can be used after flowering, which is helpful for later growth.
3. soil.
The soil can be composed of 4 parts peat soil+1 perlite+1 pine needle soil. The soil is rich in nutrients, strong in water retention, soft, breathable and slightly acidic, which is very suitable for planting gardenia.
4. Lighting.

In summer, the temperature is high and the light intensity is high, so it is necessary to take shading measures to prevent the leaves from turning yellow.
Step 5 trim.
The main pruning time of Gardenia jasminoides Ellis is in the growth period of May-July and the dormant period of about 65438+February, and there is no need for excessive pruning in these two stages. When the growth is relatively strong, you can cut off the branches and leaves that are too long, too dense and not growing well. They look messy, and the branches and leaves that have a great influence on growth and ornamental should also be trimmed appropriately.
After the plant grows buds, it is necessary to remove the buds that are not growing well, keep the robust buds, ensure the flowering quality, and make the plant blossom big and full.
