What to do when the leaves of gardenia turn yellow
The editor explains the knowledge content of what to do when the leaves of gardenia turn yellow, including the treatment methods for yellowing leaves of gardenia, the following is a detailed introduction for you
1. Increase ventilation, as poor air circulation easily breeds various bacteria, leading to unhealthy plant growth and causing yellowing and falling leaves.
Solution: Place the gardenia in a well-ventilated area. Indoors, you can open the windows for ventilation from time to time, but as long as there is enough space and the doors are not closed for a long time, there won't be any problems.
2. Supplement iron in time, gardenia growth is inseparable from iron elements, and if the environment lacks iron, it can easily lead to yellowing and falling leaves.
Solution: There are usually two possibilities for iron deficiency. The first is severe soil alkalization, which hinders the absorption of iron; the second is low iron content in the environment. Therefore, on one hand, it is necessary to improve the soil quality by watering with acidified water, and on the other hand, you can spray ferrous sulfate on the leaves for supplementation.
3. Fertilize appropriately, as insufficient nutrients can lead to poor growth of gardenia, resulting in yellowing and falling leaves.
Solution: It is usually caused by a lack of nitrogen, but excessive nitrogen fertilization should be avoided when fertilizing. Excessive nitrogen can easily cause plant elongation and hinder flowering. Apply a little compound fertilizer to provide more comprehensive nutrition.
