Why gardenia flowers only grow leaves but do not blossom
1. Pruning problem
(1) specific reason: some plants will grow very luxuriantly. If there is no pruning for a long time, then nutrients will be supplied to the stems, leaves and other parts first, then the growth of buds will be hindered.
(2) solution: it is best to prune the plant regularly, but it is certainly impossible not to cut it for a long time.
2. Fertilizer problem
(1) the specific reason: the main reason is that the type of fertilizer is wrong. Specifically, there is too much fertilizer containing N, which leads to the rapid growth of leaves. However, there is too little fertilizer containing P, and the flowers will not bloom. In this way, the plants appear to be very exuberant, but in fact they are only leaves without flowers.
(2) solution: phosphate fertilizer is of great significance to flowers. Especially when flower buds begin to differentiate, we must use more phosphate fertilizer and less nitrogen. For example, (KH2SO2) solution, etc.
3. Water problem
(1) specific reason: before gestating buds, if too much water is watered, the leaves of the plant will grow very fast, but the flowers will grow less.
(2) solution: in the bud period, the appropriate reduction of some water.
4. Temperature problem
(1) specific reason: here mainly refers to the winter plant dormancy when the temperature is too high. In this way, the dormancy of the plant will be broken prematurely, and then the buds and leaves will be issued prematurely, consuming a lot of nutrients. When it is time to blossom, the number of flowers will be very small.
(2) solution: the temperature during dormancy had better be about five degrees, and it is safe to spend the winter.

What if the gardenia grows too high?
The main reason for this is that it has not been trimmed for too long. Pruning is very important for this plant. Moreover, it must be at the right time. First, it is in spring. Cut off the overlong branches and the overgrown flower branches. The second is from May to July, again, in order to promote the germination of branches, but also so that it will not grow too tall. In addition, you also need one after the flowers fade. Another reason is that there is too much fertilizer, which leads to the overgrowth of plants, which can be adjusted properly.

Why don't gardenias grow buds
When this happens, the most important thing is the problem of fertilizer. Only pay attention to nitrogen fertilizer, then it will only grow and will not grow buds. Even if there is a bud, it is easy to fall. Then there is the problem of light, which is too weak to cause buds to grow. Then there is something wrong with the roots, such as stagnant water or slabs of soil, so that there is no way to provide enough nutrients, so the buds naturally cannot grow out. Finally, there is the problem of temperature. if it is not suitable, it is difficult for the buds to grow.
