Why Is My Laurel Hedge Going Yellow or Brown? Causes and Fixes

By Paul Watmore, Director at Grasslands Nursery

Yellowing or browning laurel is most often caused by waterlogged or compacted soil, drought stress, frost or wind scorch, or hedge-trimmer damage — rarely by disease. A few cut-edged brown leaves are only cosmetic, but widespread yellowing or dieback usually means the roots are sitting too wet or too dry. Here is how to diagnose and fix it.

Quick diagnosis

• Yellow leaves dropping, soil wet and heavy → waterlogging (most common).
• Crispy brown leaves in summer, dry soil → drought stress.
• Browning on one exposed side after cold or wind → frost or wind scorch.
• Ragged brown leaf edges after cutting → hedge-trimmer damage (cosmetic).
• Pale, yellowy new growth → possible nutrient shortage.

1. Waterlogged or compacted soil (the usual culprit)

Laurel hates wet feet. In heavy clay or poorly drained ground the roots cannot breathe, leaves turn yellow and drop, and growth stalls. Improve drainage by forking in grit and organic matter, avoid planting in a hollow, and never let the hedge sit in standing water.

2. Drought and under-watering

Newly planted hedges, plants at the base of a wall or fence, and established hedges in a hot dry spell can all suffer drought, giving crispy brown leaves. Water deeply (a good soak once or twice a week rather than a daily sprinkle) and mulch to hold moisture in.

3. Frost and wind scorch

Cold winds and hard frosts can brown the exposed face of a laurel hedge, especially on tender new growth. This is usually cosmetic — trim out the worst once the risk of frost has passed and fresh growth will hide it.

4. Hedge-trimmer damage

A powered trimmer slices through laurel’s large leaves, and the cut edges then brown. It looks unsightly but does no real harm. Use secateurs for a clean finish — see our guide to trimming a cherry laurel hedge.

5. Nutrient shortage

Pale or yellowing leaves on poor soil can signal a lack of nutrients (often nitrogen). Feed in spring with a general or hedging fertiliser and mulch with well-rotted organic matter.

How to revive a struggling laurel hedge

Check the drainage and watering first — these fix most cases. Then feed in spring, mulch, trim out clearly dead growth to encourage fresh shoots, and be patient: laurel is tough and reshoots well from healthy wood once the underlying problem is solved.

FAQs

Why is my laurel hedge turning yellow?
The most common cause is waterlogged or compacted soil, which stops the roots breathing and turns leaves yellow. A spring feed helps if it is a nutrient shortage, but check drainage first.

Why does my laurel have brown leaves?
Usually drought stress, frost or wind scorch, or damage from a hedge trimmer cutting the large leaves. Crispy brown edges in summer point to dryness; ragged cut-edges are trimmer damage.

Is my laurel being over- or under-watered?
Both can brown a laurel. Waterlogged roots cause yellowing and leaf drop; drought causes crispy brown leaves. Check the soil — if wet and heavy, improve drainage; if dry, water deeply and mulch.

Will my laurel hedge recover?
Usually yes, once the cause is fixed. Laurel is tough and reshoots from healthy wood. Correct the watering or drainage, feed in spring, mulch, and trim out any dead growth.
