When does the gardenia bloom?
Today's focus is to introduce when gardenias bloom and some small experiences in plant cultivation concerning the blooming season of gardenias. If there are any mistakes, please feel free to correct them!
Gardenias are native to China and are cultivated in most parts of the country, mainly concentrated in East China, Southwest, and Central South regions. They are important ornamental plants for gardens, but do you know when gardenias bloom? What are the reasons why gardenias don't bloom? Let's take a look together!
When do gardenias bloom?
Gardenias prefer a warm, humid semi-shaded environment, slightly shade-tolerant, and afraid of strong sunlight exposure. The blooming period is relatively long, from May to June continuously blooming until August, and the fruit ripening period is in October. However, a single flower only blooms for 4-5 days. If fertilized sufficiently, there will be more flower buds, and the blooming period will be longer.
Blooming conditions for gardenias
Gardenias thrive in a humid atmosphere with sufficient light and good ventilation. In summer, they should be protected from direct sunlight and prefer to grow in a slightly shaded area. They are shade-tolerant, fear waterlogging, and can withstand cold temperatures. The most suitable growth temperature is around 16 degrees Celsius. In winter, the temperature should not be lower than 0 degrees; otherwise, they will enter a dormant period. In Northeast, North, and Northwest China, they can only be grown as greenhouse potted flowers.
Gardenias should be planted in loose, fertile, well-draining, slightly clayey acidic soil and are typical acid-loving flowers.
What are the reasons why gardenias don't bloom?
1. Improper watering and fertilizing: 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 blooming or very few flowers. Some may even fall off immediately after opening. 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 development. Over-fertilization during the bud development stage and irregular watering can also cause flowers and seedlings to fall off.
2. Inappropriate lighting: Gardenias prefer shade, so special attention should be paid to excessive sunlight in summer and weak sunlight in winter. Both too much and too little light can affect gardenias blooming.
3. High alkalinity in the soil: Gardenias prefer acidic soil. If the soil for cultivating gardenias contains high salt or alkali, it will cause the plant to turn yellow, ultimately affecting blooming.
4. Lack of pruning and shaping: The branches of gardenias are chaotic, and a large number of杂枝 consume a lot of nutrients. Overly dense branches also affect photosynthesis, which are important reasons for not blooming.
5. Severe pests and diseases: This is understandable to everyone. Severe pests and diseases will inevitably cause flowers and buds to fall off.
