Gardenias are evergreen shrubs with white and elegant flowers, and their leaves remain green throughout the year. The flowers emit a fresh and pleasant fragrance, making them an important ornamental plant for gardens. Gardenias are not only beautiful in appearance but can also be used in medicine, having the effect of clearing heat and detoxifying. The flower language of gardenias is eternal love, and they are often used for declarations and expressions of love. During the cultivation of gardenias, pruning is often necessary to promote their growth. So how should it be done? Let's find out together.
I. Pruning Methods
1. Pruning Time
Pruning of gardenias is generally done in spring and autumn when the weather conditions are good. Since gardenias grow relatively fast, timely pruning is very necessary, and proper pruning can promote healthier growth of the plants. Choosing to prune in spring and autumn, when temperature and humidity conditions are relatively suitable, can reduce the adverse effects on gardenias.
2. Retain Three Main Branches
When pruning, first select three main branches that need to be retained. Then, cut off all lateral branches that grow from 15 centimeters above the base of these three branches. The purpose is to concentrate the lateral branches in the upper part of the main branches. Also, pay attention to cutting off branches that grow from the rootstock.
3. Cut Off Diseased and Weak Branches
Pay attention to cutting off branches that are not growing well and those infected by diseases and pests. Weak branches will divert nutrients from healthy branches, which is not conducive to the healthy growth of the plant; branches affected by pests and diseases will also threaten healthy branches.
4. Cut Off Excessive Growth Branches
Trim excessive growth branches when gardenias are in a vigorous growing period. This promotes the growth of lateral branches and allows the plant to produce more flowers.
5. Remove Flower Buds
Remove flower buds appropriately, leaving only 2-3 flower buds on strong branches, and only one or none on branches that are growing slightly worse.
II. Precautions
1. Ensure Ventilation
Gardenias like light and are also drought-resistant. After pruning, it is beneficial to place them in a well-ventilated outdoor area, which aids in their growth and recovery.
2. Water and Fertilizer Management
Water gardenias when the soil is completely dry to promote recovery. When watering, use water that has been exposed to sunlight and avoid getting it on the cuts. Also, fertilize gardenias in a timely manner, using nutrient solutions and adding some to the water when watering.
3. Prevent Diseases and Pests
After pruning, spray gardenias with fungicides because the cuts left on the plant can be easily invaded by bacteria when the plant's resistance is weak. Therefore, it is necessary to spray the plant with antiseptic drugs after each pruning.
