Why leaves turn brown at the edges

Brown edges on leaves are one of the most common signs of plant stress. They rarely mean a plant is dying, but they do indicate something in its environment is off balance.

What's happening

Leaf edges lose moisture first. In Indian summers, when balcony temperatures cross 40°C, even well-watered plants lose moisture faster than roots can supply. Browning usually accelerates during May-June when dry heat peaks.

Why this happens

Dry soil, harsh direct sunlight, low humidity, or salt buildup from fertilizers or hard municipal water all contribute. Terracotta pots wick moisture faster than plastic, speeding up edge browning in hot weather.

What usually helps

Water thoroughly and let excess drain. Move the plant away from harsh 12-4 PM sun. If you suspect salt buildup, flush the pot by running water through slowly until drainage runs clear. Grouping plants together raises local humidity.

What to expect next

Damaged edges will not heal, but new leaves should grow healthier within one to two weeks if conditions improve. Trim brown edges with clean scissors for a tidier look.
