What to do when hibiscus leaves turn yellow
Today's focus is on how to deal with yellowing leaves of hibiscus and related reasons for yellowing leaves and solutions for green plant maintenance tips, let's get to know them together.
Improper lighting: Hibiscus is not tolerant to strong light, as strong direct sunlight can cause yellowing leaves, so it needs to be provided with diffused light.
Improper watering: Avoid watering too frequently, as waterlogging can cause root rot and yellowing leaves, keep the soil moist.
Inadequate nutrients: Insufficient fertilization or a single nutrient can lead to yellowing leaves due to insufficient nutrient absorption, so it's important to balance top dressing.
Untimely pruning: Failure to prune in a timely manner can consume nutrients, and leaves will turn yellow if the plant cannot absorb nutrients.
Inappropriate potting: Improper timing for repotting can cause the plant to become maladjusted, leading to leaves turning from green to yellow.
I. Improper lighting
Hibiscus is a plant that does not tolerate strong light, and strong direct sunlight can cause yellowing leaves. During the maintenance of hibiscus, when the light is too strong, it should be provided with appropriate shading protection to avoid yellowing and burning of the leaves caused by strong sunlight. The plant should be placed in a place with diffused light to better promote its growth and development.
II. Improper watering
Hibiscus is a plant that likes water. During the maintenance of hibiscus, frequent watering and excessive water can cause waterlogging and root soaking, leading to yellowing leaves. Insufficient water can also cause yellowing leaves due to insufficient water absorption by the plant. Watering can be done based on the dryness and moisture of the soil, keeping it moist.
III. Inadequate nutrients
Hibiscus requires a lot of fertilizer. During the maintenance of hibiscus, insufficient or overly single fertilization can cause yellowing leaves due to insufficient nutrient absorption. Phosphorus and potassium fertilizers are the best choice for supplementing nutrients, with a fertilization interval of once every 30 days.
IV. Untimely pruning
Hibiscus is a shrub-like plant that grows quickly. After flowering in spring, it should be pruned appropriately. Failure to prune in a timely manner or not pruning at all can consume a large amount of nutrients from the plant, leading to yellowing leaves.
V. Inappropriate potting
During the maintenance of hibiscus, regular repotting is important. Repotting during the plant's vigorous growth period or flowering period can lead to yellowing leaves, as the plant requires a lot of nutrients at this time. Repotting then can cause the plant's roots to be unable to absorb enough nutrients, leading to yellowing leaves. Attention should be paid to temperature and timing control during repotting to help improve the plant's survival rate.
VI. Pest and disease invasion
During the maintenance of hibiscus, if it is affected by pests and diseases, the nutrients in the leaves will be absorbed by the pests, leading to wilted and yellowing leaves. Organic phosphorus pesticides can be used for pest and disease control, and proper handling of pests and diseases can better improve plant growth.
These are all the contents about what to do when hibiscus leaves turn yellow and the analysis of the reasons for yellowing leaves and solutions. Green plant enthusiasts might find it useful for reference.
