What to do if the gardenia buds turn yellow

1. Water appropriately

1. Reason: Although gardenia is a moisture-loving plant, if it is watered too much, it will affect the roots' absorption of nutrients and the flower buds will turn yellow.

2. Solution: Water appropriately to make the soil moist but not waterlogged. Water the gardenia every two to three days during the flowering period, and spray the gardenia buds with water in the morning and evening.

2. Increase fertilization

1. Reason: Gardenia is a plant that likes fertilizer. Insufficient fertilizer will not meet its needs, especially during the flowering period when the nutrient consumption is particularly high. If the nutrients cannot keep up, the flower buds of gardenia will turn yellow.

2. Solution: It is best to fertilize gardenias two to three times a month, and once a week during the flowering period. However, the amount of fertilizer should not be too much to avoid root burn.

3. Change the soil quality

1. Reason: Gardenia is an acidic plant, and acidic soil is more suitable for its growth. Alkaline soil cannot guarantee its healthy growth, and the flower buds will turn yellow.

2. Solution: Monitor the soil pH value at any time. Once the soil is alkaline, measures must be taken. You can mix leaf mold into the soil to change the soil quality and make it acidic.

4. Eliminate pests

1. Reason: Gardenia is infected by pests, and the buds may turn yellow.

2. Solution: If the branches and leaves are infected with pests, you can use cypermethrin to eliminate the pests. Please refer to the instructions for specific methods. If the soil is infected with pests, the soil must be replaced and the soil and pots must be thoroughly sterilized and disinfected.
