When growing gardenias, one may encounter situations where the leaves turn yellow or the leaves are green but the flowers do not bloom. Gardeners may wonder what to do if the gardenia does not bloom. It is difficult to accurately pinpoint the reason for non-blooming, and one can only analyze it from various aspects. Gardeners can troubleshoot on their own. Here are some common reasons for gardenias not blooming.
First, improper watering and fertilization. Excessive watering and fertilizing can cause the plant to grow excessively, and without enough nutrients for reproductive growth, it will affect the formation of flower buds, leading to no flowers or very few flowers. Some may even fall off immediately after blooming. During the flower bud differentiation period, special attention should be paid to the combination of phosphorus and potassium fertilizers, such as a 0.2% potassium dihydrogen phosphate solution, which is beneficial for flower bud formation and bud setting. Over-fertilization during the bud setting period and irregular watering can also cause flowers and seedlings to fall off.
Second, unsuitable lighting. Gardenias prefer shade and special attention should be paid to strong sunlight in summer and weak sunlight in winter. Both too much and too little light can affect gardenia flowering.
Third, high alkalinity in the soil. Gardenias prefer acidic soil. If the soil for growing gardenias has high salt or alkalinity content, it will cause the plant to turn yellow, ultimately affecting flowering.
Fourth, not pruning and shaping. The tangled branches of gardenias consume a lot of nutrients, and dense branches affect photosynthesis, which are important reasons for non-blooming.
Fifth, serious pests and diseases. This is easy to understand; serious pests and diseases will inevitably cause flowers and buds to fall.
