Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or limp to the touch. The soil stays wet for more than four days.
What to do: Allow the top inch of soil to dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
PossibleHow to tell: Older leaves turn yellow while veins remain green. This often happens when the plant has been in the same pot for a long time.
What to do: Apply a balanced, water soluble fertilizer once every two weeks during the growing season. Use a formula specifically designed for hibiscus to ensure it gets enough magnesium and iron.
