# What is leaf scorch?

Leaf scorch is browning or drying at the edges and tips of leaves, or between the veins, that happens when a leaf loses water faster than the roots can supply it. It is a symptom, not a disease, and heat, wind, dry or frozen soil and damaged roots are the usual causes.

## How to recognise leaf scorch

The browning starts at the leaf margin and creeps inward, often with a yellow band between the green and the brown. It shows first on the sides of the tree facing the sun and the wind, and on the leaves furthest from the trunk. On conifers the tips of needles turn brown instead.

Scorch usually appears across the whole tree or one whole side of it. Spots, rings or blotchy patches on single leaves point to something else.

## Why it matters in Northern Nevada

Hot dry summers, low humidity and the afternoon winds of the valley floors push trees hard. Maples, birches and other species used to wetter places often scorch in July and August. Winter can cause it too: when the ground is frozen or dry and the wind blows, evergreens lose water they cannot replace. The Cooperative Extension guide for high-desert landscapes explains why watering depth and timing matter so much here. See [watering mature trees in the high desert](https://battleborntreeservice.com/guides/watering-mature-trees-high-desert/).

A tree that scorches every year may be telling you about its roots: a lawn sprinkler that wets only the surface, soil that is compacted, or roots cut during construction.

## What an arborist does about it

The arborist asks what is stressing the roots before deciding anything about the leaves. Scorched leaves do not recover, so the question is whether the tree is losing limbs or only this season's foliage. If dieback follows, the dead wood can be pruned out (see [dead wooding explained](https://battleborntreeservice.com/guides/dead-wooding-explained/)) and a tree that has failed can be removed. We do not spray or fertilize; we assess and prune or remove.

Note when it started and which side of the tree it hit first. Scorch that follows a hot, windy week and stays on the exposed side is a different story from scorch that spreads each year, and the arborist will ask about both.
