Answering netizens' questions on how to prune gardenias and providing illustrated pruning methods for green plant maintenance, the editor of this site will introduce the following.
Gardenia is an evergreen shrub with white and elegant flowers, green leaves all year round, and a fresh and pleasant fragrance, making it an important garden ornamental plant. Gardenias not only have a beautiful appearance but can also be used as medicine, with the effect of clearing heat and detoxifying. The flower language of gardenia is eternal love, 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
Gardenia pruning 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 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 Three Main Branches
When pruning, first select three main branches that need to be retained. Then, cut off all side branches that grow from 15 cm above the base of these three main branches, aiming to concentrate the side 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 branches infected with diseases and pests should not be left. Weak branches will take away nutrients from healthy branches, which is not conducive to the healthy growth of the plant; branches infected with pests and diseases will also threaten healthy branches.
4. Cut Off Excessive Growth Branches
Shorten the branches that grow excessively. When gardenias are in a period of vigorous growth, pruning excessive growth branches is beneficial for their growth. Mainly, pruning excessive growth branches can promote the growth of side branches, which can result in more flowers on the plant.
5. Remove Flower Buds
Remove flower buds appropriately, leaving only 2-3 flower buds on strong branches, and only one or none on branches with weaker growth.
II. Precautions
1. Ensure Ventilation
Gardenias like sunlight and are relatively drought-resistant. After pruning, it is beneficial to place them in a well-ventilated outdoor area to promote their growth and recovery.
2. Water and Fertilizer Management
When the soil around gardenias is completely dry, water them to promote recovery. When watering, use water that has been exposed to sunlight and avoid pouring it directly on the cuts. Also, pay attention to fertilizing gardenias in a timely manner, using nutrient solutions and adding some nutrient solutions to the water when watering.
3. Prevent Diseases and Pests
After pruning, spray the gardenias with fungicides. This is because pruning leaves many cuts on the plant, and after pruning, the plant's resistance is relatively weak, making it susceptible to infection. Therefore, it is necessary to spray the plant with sterilizing agents after each pruning.
