What to do if gardenia does not bloom

1. Reasonable fertilization

1. Reason: Gardenia is a plant that likes fertilizer, especially during the growing and flowering periods, when it has a greater demand for nutrients. If the nutrients cannot keep up, gardenia will not bloom.

2. Solution: Normally, fertilize twice a month, and once a week during the flowering and growing seasons. The amount of fertilizer should not be too much, as too much will burn the roots.

2. Increase Lighting

1. Reason: Insufficient light will affect the health of sun-loving plants. Gardenia is one of these plants. Insufficient light will prevent it from blooming.

2. Solution: Make sure it has 8 hours of natural light every day, but gardenia cannot be exposed to strong light, so it needs to be properly shaded when the sun is strong at noon, and no special treatment is required at other times.

3. Acidification of soil

1. Reason: Gardenia is an acid-loving plant, so acidic soil is more suitable for its growth, and alkaline soil does not conform to its growth characteristics.

2. Solution: Check the pH value of the soil frequently. If the soil becomes alkaline, add some leaf mold to the soil, or add a few drops of vinegar to make it acidic.

4. Proper pruning

1. Reason: The branches and leaves of gardenia grow very fast. If they are not pruned, the nutrients of the plant will be too dispersed, causing it to not bloom.

2. Solution: Properly prune the gardenia and cut off all the dead branches and leaves to make the nutrients more concentrated, which is conducive to the flowering of the plant.
