Brown spots on plant leaves can be caused by several factors. Understanding the cause is key to solving the issue and keeping your plants healthy:
Overwatering often leads to fungal infections, which can cause brown spots. Ensure your plant’s soil is well-draining and water only when the top inch of soil is dry.
Underwatering can also cause brown, dry spots on leaves. Check the soil moisture regularly and water consistently to prevent dehydration.
Exposure to direct sunlight can scorch leaves, resulting in brown patches. If your plant prefers indirect light, move it to a less sunny spot.
Pests like spider mites, thrips, or aphids can create brown spots as they feed on leaves. Inspect your plants for pests and treat infestations using natural methods such as neem oil or insecticidal soap.
Nutrient deficiencies, especially a lack of potassium or calcium, can lead to browning. Feed your plant with a balanced fertilizer to provide the necessary nutrients.
Fungal or bacterial infections may cause brown or black spots. Remove the affected leaves and treat the plant with a natural fungicide or bactericide.
Low humidity can cause leaves to dry out and develop brown edges or spots. Increase humidity by misting your plant or using a humidifier.
Root damage due to poor soil conditions or over-fertilizing can lead to leaf browning. Repot your plant in fresh soil if you suspect root issues.
By addressing these potential problems, you can help your plants recover and prevent future brown spots.
