How to Prune Gardenias
You may not be familiar with how to prune gardenia branches and leaves or the illustrations of gardenia pruning methods. The following is an introduction for you.
Gardenia is an evergreen shrub with white and elegant flowers, and its leaves remain green throughout the year. The fragrance of the flowers is fresh and pleasant, making it an important courtyard ornamental plant. Gardenia is not only beautiful in appearance but can also be used as medicine, having the effect of clearing heat and detoxifying. The flower language of gardenia is eternal love, and it is often used for 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
Gardenia pruning is generally done in spring and autumn when the weather conditions are good. Gardenias grow relatively fast, so timely pruning is very necessary. Moderate pruning can even promote healthier growth of gardenias. Choosing to prune in spring and autumn when temperature and humidity conditions are relatively suitable can reduce the adverse effects on gardenias.
2. Retain 3 Main Branches
When pruning, first select three main branches to keep. 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 middle and upper parts of the main branches. Also, pay attention to cutting off branches that grow from the rootstocks.
3. Cut Off Diseased and Weak Branches
Pay attention to cutting off branches that are not growing well, and branches infected with diseases and pests should not be left either. Weak branches will divert nutrients from healthy branches, which is not conducive to the healthy growth of the plant; branches affected by pests can also threaten healthy branches.
4. Cut Off Excessive Growth Branches
Trim the excessive growth of branches. When gardenias are in a more vigorous growth period, trimming the excessive growth is beneficial to their growth. Mainly, pruning the excessive growth branches can promote the growth of lateral branches and thus make the plant 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 poorly.
II. Precautions
1. Ensure Ventilation
Gardenias like light and are also drought-resistant. After pruning, you can place them in a ventilated outdoor area, which is beneficial for their growth and recovery.
2. Water and Fertilizer Management
When the soil around the gardenias is completely dry, be sure to water them to promote recovery. When watering, use water that has been exposed to sunlight and try not to pour it on the cuts. Also, pay attention to fertilizing the gardenias in a timely manner, using nutrient solutions, and you can also add some nutrient solution when watering.
3. Prevent Diseases and Pests
After pruning, spray the gardenias with fungicides because many cuts will be left on the plant, and after pruning, the plant's resistance will be relatively weak, making it vulnerable to pathogens. Therefore, it is necessary to spray the plant with antiseptic drugs after each pruning.
