Why Are My Cedars Turning Brown? Main Causes and Solutions

A cedar hedge is an important investment for your property. When it starts turning brown, it is normal to be concerned. Fortunately, many causes can be identified quickly and, in many cases, corrected before the damage becomes permanent.

The Most Common Causes

Lack of Water

Young cedars need regular watering, especially during periods of hot weather. A lack of water can cause the tips to turn brown and may slow down growth.

Harmful Insects

Pests such as cedar leafminers, spider mites, and scale insects can weaken cedar hedges. Early signs often include changes in foliage color, drying branches, or foliage loss.

Winter Stress

Cold winds and lack of moisture during the winter can dry out cedar foliage. This problem is common in Quebec and often becomes noticeable in the spring.

Improper Fertilization

Soil that lacks essential nutrients can limit growth and weaken cedar trees. Proper fertilization can help restore strength, improve color, and encourage healthy growth.

How Can You Prevent Cedar Browning?

• Water regularly during dry periods.

• Inspect your hedge several times per year.

• Apply pest control treatments when necessary.

• Fertilize in the spring.

• Trim your cedar hedge annually.

Acting quickly can often save a cedar hedge before the damage becomes irreversible.
