1、 When does it open

Gardenia jasminoides is widely distributed in most areas of China. It usually opens from May to August in summer, but the flower opening in different regions is different and is not a fixed unified time. The temperature in the south is higher and warmer. The heat concentration in these areas is faster, and the flowering time will be earlier. Some can bloom at the beginning of May. Because of regional factors in northern areas, the flowering time is later, and some can not bloom until about August. Gardenia has a long viewing period. A single flower can open for 3-4 days, and a whole Gardenia can open for about a month. Under the appropriate environment, the flowering time will be prolonged

2、 Reasons for not flowering

1. Insufficient light: insufficient light will affect the flowering, resulting in the failure of flowers to bloom normally, so it is necessary to give reasonable sunshine

2. No pruning: usually do not pay attention to pruning and shaping, resulting in too messy branches, which will consume a lot of nutrients and make it difficult for flowers to bloom. At ordinary times, it can be trimmed reasonably according to the needs of growth

3. Soil discomfort: Gardenia likes to grow in acidic soil. If alkaline soil is used, it is easy to cause poor growth and flowers are difficult to open. Acid substances need to be added regularly

4. Lack of fertilizer: without fertilization for a long time, the plant has no nutrients, and there is no nutrient support for flowering, which will also lead to failure of flowering. It is necessary to apply fertilizer reasonably and increase phosphorus and potassium fertilizer at flowering stage
