What to Do When Plant Leaves Turn Brown
Discoloured leaves can be a sign of several issues affecting your plant's health. Identifying the cause is crucial to provide the appropriate treatment.
Nutrient Deficiency: Brown or yellow leaves with green veins indicate a lack of nitrogen, iron, or magnesium. Amend the soil with a balanced fertilizer.
Overwatering: Soggy soil and waterlogged roots can suffocate plants, leading to brown, mushy leaves. Allow the soil to dry out before watering again.
Sunburn: Prolonged exposure to intense sunlight can scorch leaves, causing dry, brown patches. Move the plant to a shadier location or provide shade with partial shade cloths.
Pests: Aphids, mealybugs, and spider mites can suck the life out of leaves, causing them to turn brown and crispy. Use insecticidal soap or neem oil to control pests.
Disease: Fungal or bacterial infections can cause leaves to develop brown spots or lesions. Treat the plant with a fungicide or antibacterial spray according to the manufacturer's instructions.
