Reasons why gardenias do not bloom

1. Reduce or increase the amount of fertilizer

1. Reason: If there is too much fertilizer when it is growing, it will cause the plant to grow too tall and affect flowering. If there is not enough fertilizer, it will lack nutrients and will not bloom. Even if a few flowers bloom, they will wither immediately.

2. Solution: Reduce or increase the amount of fertilizer appropriately, mainly phosphorus and potassium fertilizers, so that flower buds can form early and it can bloom.

2. Reduce or increase light

1. Reason: It prefers a cool environment. If it is not properly shaded in the summer, the excessive light will burn it and affect its flowering. But the light cannot be too weak, especially in winter, otherwise it will affect its growth.

2. Solution: In summer, provide it with appropriate shade to avoid too strong light; in autumn and winter, increase the lighting time so that the plant can grow normally.

3. Choose the right soil

1. Reason: It prefers acidic soil. If too alkaline soil is used, the plant will turn yellow and not bloom.

2. Solution: Choose suitable soil, mainly acidic.

4. Proper pruning

1. Reason: If it is not pruned for a long time, the branches will become too long and messy, which will consume a lot of nutrients, affecting the normal growth of the plant and causing it to not bloom.

2. Solution: When you see that its branches are too long or messy, you should prune them appropriately to prevent the branches from being too dense. This way, the flower buds will get more nutrients to make it easier for them to bloom.
