Crispy Leaf Edges: Causes, Diagnosis & Fixes
When leaf margins become brown and crispy while the center stays green, it typically indicates a moisture or environmental issue.
Quick diagnosis
Crispy leaf edges are the plant telling you it needs more moisture — either in the soil, the air, or both. Check for fertilizer salt buildup as well.
考えられる原因
Low Humidity
Why: Tropical plants lose moisture from leaf edges first when surrounding air is too dry.
Signs to check: Edges are dry and papery, problem worsens in winter with indoor heating.
Underwatering
Why: When the plant does not receive enough water, leaf edges — the farthest points from the stem — dry out first.
Signs to check: Soil is frequently dry, crispy edges progress inward over time, plant may also wilt.
Fertilizer Burn
Why: Excess fertilizer salts accumulate in the soil and damage leaf margins.
Signs to check: White crust on soil surface, crispy edges appeared after fertilizing, tips and edges brown together.
Root Restriction
Why: A severely root-bound plant cannot deliver enough water to leaf margins.
Signs to check: Roots visible at surface or drainage holes, crispy edges despite regular watering.
