Every summer, walking on the streets, one can smell the refreshing fragrance of gardenias. It is precisely because of their strong fragrance that gardenias are deeply loved by many flower enthusiasts, and many people keep some gardenias as potted plants at home. July is when gardenias grow most vigorously, and pruning is usually necessary at this time to allow nutrients to concentrate. After the gardenias finish blooming and prepare for winter, usually at the end of the year, a second round of pruning is often required. Let's delve into the pruning of gardenias in July, at the end of the year, and how to pinch the top.
1. July Pruning
During the vigorous growth period of gardenias, which is at the end of July, we can remove the top of the plant to promote the sprouting of branches, making the future plant shape more beautiful and the flowers more abundant. We can also observe the size of the entire canopy, cut off some weak branches and branches that grow inward, and trim the base's weak and thin branches to keep the plant shape clear and ventilated. For overly long branches that make the canopy look unbalanced, it is recommended to trim them to maintain a full canopy.
2. End-of-Year Pruning
When gardenias finish blooming and prepare for winter, if the leaves at the bottom of the plant have fallen off and only leaves and flowers grow at the top, we can forcefully prune a part of the top branches to allow side buds to grow below, thus disrupting the apical dominance and supplying nutrients to the lateral branches to promote the growth of side buds. In winter, with low temperatures and relatively slow growth, there will be a dormant period. At this time, we can also prune some branches, remove withered leaves from the spent flower branches, and cut off the faded flowers to conserve nutrients for winter.
3. How to Pinch the Top
The new branches of gardenias will continue to grow. Although the branches grow very fast, we cannot allow them to grow indefinitely, as this will make the plant shape very unattractive. At this time, we can pinch the top of the plant. This involves removing the top bud and the pair of leaves below it when the new branches have grown to four or five pairs of leaves, leaving two to three pairs of leaves, or two to three nodes. This will cause the branches to age gradually, and after aging, they will produce lateral branches. When the side buds grow to four or five pairs of leaves, we continue to pinch the top to maintain a round plant shape. When new buds stop growing in autumn, the branches will age and produce flower buds. At this time, apply an appropriate amount of phosphorus and potassium fertilizer, such as monopotassium phosphate, twice to three times a month. This will result in blooming in autumn. Note that at this time, sufficient fertilizing, watering, and sunlight are essential, as the plant grows very fast. Watering should never be lacking, and the plant should be placed in a well-ventilated, sunny area. If gardenias have been kept indoors, they should be gradually moved to a sunny location and can be exposed to direct sunlight, as long as they are watered sufficiently. They will grow very fast.
