Brown Leaf Tips: Causes and Fixes

Brown leaf tips on otherwise green leaves are one of the most misdiagnosed problems in horticulture. Most gardeners immediately suspect a fungal disease. Most of the time, it isn't -- it's a cultural or environmental issue affecting water movement through the plant, and no fungicide will.

Brown leaf tips on otherwise green leaves are one of the most misdiagnosed problems in horticulture. Most gardeners immediately suspect a fungal disease. Most of the time, it isn't — it's a cultural or environmental issue affecting water movement through the plant, and no fungicide will help.

The brown is dead tissue. It does not recover. Fixing the cause stops new browning from progressing, but the existing brown tip stays brown. Cutting off the brown tip with scissors or pruners is cosmetically fine and does not harm the plant, but the brown will return if the underlying cause isn't resolved.

How Brown Tip Differs From Brown Spot or Brown Edge

Before diagnosing, confirm you're looking at brown tips specifically:

• Brown tips: Browning confined to the tip of the leaf, progressing inward from the tip. The transition from healthy to brown is usually gradual (tan to brown)
• Brown edges: Browning along the leaf margin; often called scorch. Usually indicates drought, salt, or wind damage
• Brown spots: Discrete spots anywhere on the leaf; more consistent with disease (fungal or bacterial), insect feeding, or cold damage
• Brown patches with yellow halo: Often disease — see the white-spots or disease diagnostic guides

This guide addresses brown tips and brown edges specifically.
