What to do if the petals of gardenia turn yellow

1. Treatment methods

When the petals of gardenia turn yellow, you need to place it in a well-ventilated place without strong light and clean the yellow petals. Buy ferrous sulfate, dilute it with water, and place it in the sun for 3-4 days, then use it to spray the plants. If you can't buy it yourself, you can also dilute it with vinegar, which can also solve the problem.

You can stop watering during the treatment period, but you should spray the leaves with spray to provide it with a moist growing environment, and then carry out normal maintenance.

2. Daily maintenance

1. Normal watering: Control the amount of watering, avoid excessive watering, and do not let water splash onto the flowers. Overwatering may also cause the petals to turn yellow.

2. Improve ventilation: When caring for it at home, you need to open windows frequently to ventilate it and try to avoid keeping it in a high temperature and hot growing environment. If it is just bought, you need to let it adapt to the current growing environment.

3. Reasonable light: When caring for gardenia at home, you need to provide it with a semi-shaded growing environment. In winter, it should be allowed to grow in a sunny place and cannot be deprived of sunlight for a long time. If there is no sunlight for a long time, it cannot carry out photosynthesis and needs appropriate sunlight exposure.
