When does the Cape jasmine usually bloom?
The Cape jasmine (Gardenia jasminoides) is native to China and is cultivated in most parts of the country, concentrated in East China and in most areas of Southwest and Central-South China. It is an important ornamental garden plant, but do you know when the Cape jasmine blooms? And what are the reasons a Cape jasmine fails to bloom? Let's take a look together below!
When does the Cape jasmine bloom?
The Cape jasmine likes a warm, humid, semi-shaded environment; it tolerates shade slightly and fears intense direct sun. Its flowering period is fairly long, blooming continuously from May-June through to August, and the fruit ripens in October. But a single flower only lasts 4-5 days. If fertilizer is ample, there are more flower buds and the flowering period is a little longer.
The flowering conditions for the Cape jasmine
The Cape jasmine likes a growing environment with humid air, ample light and good ventilation. In summer, direct sunlight should be avoided; it is best kept in a slightly shaded spot. It tolerates semi-shade, fears waterlogging and is fairly cold-hardy. The most suitable growing temperature is around 16°C, and in winter the temperature must not fall below 0°C; if it is too low, the plant will enter a dormant period. In Northeast China, North China and Northwest China it can only be grown as a potted greenhouse flower.
The Cape jasmine is best planted in loose, fertile, well-drained, slightly clayey acidic soil; it is a typical acid-loving flower.
What are the reasons a Cape jasmine fails to bloom?
1. Improper water and fertilizer: once water and fertilizer are excessive, the plant will grow excessively, and without enough nutrients for reproductive growth, flower bud formation will be affected, resulting in no flowering or very few flowers; some that do open may even drop immediately. During the flower bud differentiation stage, special attention should be paid to the balance of phosphorus and potassium fertilizers, such as a 0.2% potassium dihydrogen phosphate solution, which helps flower bud formation and bud development; applying fertilizer that is too concentrated during the bud stage, or watering now too much and now too little, will also cause flowers and seedlings to drop.
2. Unsuitable light: the Cape jasmine likes shade, and special attention must be paid to light that is too strong in summer and too weak in winter; light that is too strong or too weak will both affect the Cape jasmine's flowering.
3. High soil alkalinity: the Cape jasmine likes acidic soil. If the soil used to grow the Cape jasmine is high in salt and alkali, the plant will turn yellow, which will ultimately affect flowering.
4. No pruning or shaping: the Cape jasmine's branches are messy, and a large number of stray branches consume a great deal of nutrients, while branches that are too dense affect photosynthesis; both are important causes of failure to bloom.
5. Severe pests and diseases: everyone can surely understand this one; severe pests and diseases will inevitably cause flowers and buds to drop.
