Improper watering: Both excessive and insufficient watering can affect the growth of gardenia. Too much water can cause root hypoxia, leading to root rot, which in turn affects the normal growth of leaves; too little water will cause the leaves to lack water and appear dry.3. Diseases and pests: Diseases and pests are also one of the reasons for the dried leaves of gardenia. The invasion of pests like red spiders and aphids, as well as infections from diseases like leaf spot and soot blight.4.

Prevent diseases and pests: Remove pests in a timely manner and use soapy water or other medications for spraying. For diseases, use medications like carbendazim or thiophanate-methyl for control.4. Supplement nutrients: Appropriate application of phosphorus and potassium fertilizers can promote root development. During the growing period, apply a dilute nitrogen fertilizer every 15 days or so to enhance photosynthesis of the leaves.5. Prune branches and leaves: For dried leaves, prune them in time to reduce nutrient consumption. Also, prune dense and weak branches to maintain ventilation and light penetration of the plant.6. Repotting and changing soil: If the soil is poor, choose an appropriate time for repotting and changing soil, using fertile and well-draining soil.
