Why does the gardenia only have leaves but no flowers?

1. Pruning problem

(1) Specific reasons: Some plants grow very vigorously. If the plant is not pruned for a long time, nutrients will be supplied to the stems, leaves and other parts first, and the growth of flower buds will be hindered.

(2) Solution: It is best to prune the plants regularly. It will not work if you do not prune them for a long time.

2. Fertilizer problem

(1) Specific reasons: The main reason is that the type of fertilizer is wrong. Specifically, too much fertilizer containing N causes the leaves to grow very quickly. However, if the fertilizer contains too little P, the flowers will not bloom. This creates a phenomenon where the plant appears to be very lush, but in fact it only has leaves and no flowers.

(2) Solution: Phosphorus fertilizer is of great significance to flowers. Especially when flower buds begin to differentiate, be sure to use more phosphorus fertilizer and less nitrogen-containing fertilizer. For example, (KH2SO2) solution, etc.

3. Moisture problem

(1) Specific reason: If too much water is applied before the buds form, the leaves of the plant will grow very fast, but the number of flowers will be small.

(2) Solution: Reduce the amount of water appropriately during the bud formation period.

4. Temperature issues

(1) Specific reasons: This mainly refers to the fact that the temperature is too high when the plants are dormant in winter. In this way, the dormancy of the plant will be broken prematurely, and then the buds and leaves will sprout prematurely, consuming a lot of nutrients. By the time it is time to bloom, there are very few flowers left.

(2) Solution: The temperature during dormancy should be around five degrees, so that the plant can safely survive the winter.
