Gardenias are evergreen shrubs with white, 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. Not only are gardenias beautiful, they can also be used in medicine to clear heat and detoxify. The flower symbolism of gardenias is eternal love, often used to express love and affection. During the cultivation of gardenias, pruning is often necessary to promote growth. So how exactly should it be done? Let's find out together.
I. Pruning Methods
1. Pruning Time
Gardenia pruning is generally done in spring and autumn when the weather conditions are favorable. Since gardenias grow relatively fast, timely pruning is necessary, and proper pruning can actually promote healthier growth. Pruning in spring and autumn, when temperature and humidity conditions are suitable, can minimize the adverse effects on gardenias.
2. Retain Three Main Branches
When pruning, first select three main branches to keep. The side branches that grow 15 centimeters above the base of these three branches should be cut off, with the aim of concentrating the side branches in the upper middle part of the main branches. Also, remove any branches that grow from the root suckers.
3. Cut Off Diseased and Weak Branches
Pay attention to cutting off branches that are not growing well, as well as those infected by diseases and pests. Weak branches can divert nutrients from healthy ones, which is not conducive to the healthy growth of the plant; branches affected by diseases and pests can also threaten healthy ones.
4. Cut Off Excessive Growth Branches
It is necessary to shorten the branches that grow excessively. During the vigorous growing period of gardenias, pruning these branches can promote the growth of side branches and result in more flowers.
5. Remove Flower Buds
Remove flower buds appropriately, leaving only 2-3 on strong branches, and only one or none on branches that are growing slightly worse.
II. Precautions
1. Ensure Ventilation
Gardenias enjoy sunlight and are drought-resistant. After pruning, they can be placed in a well-ventilated outdoor area, which is beneficial for their growth and recovery.
2. Water and Fertilizer Management
Water the gardenias when the soil is completely dry to promote recovery. When watering, use water that has been exposed to sunlight and avoid pouring it directly on the cuts. It is also important to 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 the gardenias with fungicides. Pruning leaves many cuts on the plant, which makes it vulnerable to diseases when its resistance is low. Therefore, it is necessary to spray the plant with sterilizing agents after each pruning.
