Common Symptoms
Dry brown leaf edges
Dry, brown, brittle areas appear along leaf edges or tips, spreading toward the center of the leaf blade.
Signs to check
- The affected area is dry, brown to black and crumbly to the touch.
- Necrosis always begins at the tip or margins, never in the center of the leaf.
- A yellow or dark brown dividing line often separates healthy tissue from the dry area.
- The oldest leaves at the base of the plant are generally affected first.
Common causes
- Air too dry (low humidity) · Ambient humidity is insufficient for tropical plants.
- Excess salts · Brown leaf tips and a white crust on the soil.
- Too little water · Soil is dry and leaves are limp and drooping.
- Anthracnose · Brown or black spots, often sunken and surrounded by a halo.
