YELLOWING LEAVES:
Yellowing leaves can indicate a range of problems, including overwatering, underwatering, or nutrient deficiencies. To help your String of Hooks recover, check the soil moisture levels and adjust watering as needed, make sure it is not sitting in standing water, and fertilize it with a balanced houseplant fertilizer according to package instructions.
LEAF DROP:
If you notice that your String of Hooks is dropping leaves, it could be a sign of stress or disease. Check to make sure that the plant is not being over or under-watered, and that it is not experiencing extreme temperature fluctuations. Additionally, inspect the leaves and stems for signs of pests or disease, such as wilting, discoloration, or spots. If you suspect a pest or disease problem, treat it with an appropriate product or consult with a local nursery or garden center for further guidance.
