1. Improve lighting. Improper lighting can cause yellow leaves in gardenias. Gardenias need warm, bright, and sufficient light to nourish their leaves. Long-term lack of light can cause leaf wilt, and proper lighting should be increased. If yellow leaves are caused by direct exposure to the sun, they should be properly shaded and changed to scattered light for nourishment.
2. Adjust water. Overwatering can easily cause gardenias to develop a yellowing phenomenon, manifested as wilted and yellow leaves mixed with green, while insufficient water will cause drought yellowing, shown by yellow and dry leaves that break easily when touched. Gardenias are water-loving plants, and as long as the soil is kept moist without waterlogging, it is sufficient.
3. Ventilation. Proper ventilation is very important in the cultivation of gardenias. If ventilation is poor, gardenias can easily develop yellow leaves, wilt, and even rot. Especially in summer, poor ventilation can cause gardenias to become stuffy. Therefore, it is necessary to move the gardenias to a semi-shaded and well-ventilated environment as soon as possible to alleviate the yellowing of the leaves.
4. Disinfect and pest control. Leaf blight, leaf rot, red spiders, and aphids are common diseases and pests that gardenias can suffer from. The yellowing of leaves caused by diseases and pests is relatively easy to solve. Choose the appropriate disinfectant and pest control agents, dilute them, and spray them to drive away diseases and pests, and then prune the yellow leaves.
