Will my tree recover on its own?

While a healthy tree might survive, the damage will likely continue to spread and weaken the plant, so active pruning is necessary.

Can I compost the dead branches?

No, the fungal spores can survive in a compost pile and spread back to your garden later, so it is best to dispose of them in the trash.

Twig Blight

Symptoms by part

Stems

The tips of the branches turn reddish brown or gray, eventually shriveling and dying back toward the main trunk.

Causes

Prolonged periods of wet or humid weather.
Poor air circulation around the canopy.
Wounds on the branches from wind, hail, or improper pruning.
Overcrowded planting sites that trap moisture.

Could be confused with

Drought stress · Drought stress usually affects the entire tree or the outer canopy uniformly, whereas twig blight typically appears as scattered, localized patches of dead tips.
Frost damage · Frost damage happens suddenly after a cold snap and affects all new growth at once, while twig blight progresses slowly over time.

Treatment

Prune away all affected branch tips during dry weather, cutting at least 4 to 6 inches below the visible damage into healthy green wood.
Disinfect your pruning shears with a solution of rubbing alcohol between every single cut to avoid moving the fungus to healthy parts of the tree.
Collect and destroy all pruned material by burning or bagging it for the trash, never composting it.

Without chemicals

Improve air circulation by thinning out crowded branches.
Water the base of the tree rather than overhead to keep the foliage dry.
Install a rain cover or temporary shelter if the tree is small enough to protect it during extended rainy spells.

Chemical options

Sulfur, apply as a spray to the foliage during the early stages of growth, follow the label.

Preventing it

Space plants properly to ensure good airflow.
Avoid wounding the bark with lawn equipment.
Keep the area around the base of the tree clear of fallen debris.
Water early in the day so the foliage has time to dry before nightfall.

Season

The warm growing season, especially during periods of high humidity or frequent rainfall.

Spread risk

Moderate

Severity

Moderate

When to act

Act as soon as you notice the first signs of browning tips to prevent the fungus from moving further down the branch. If the damage covers more than half of the tree or involves large limbs high up, contact a tree surgeon for safe removal.
