Known for their resilience and sheer beauty, cedars are favourites throughout the Lower Mainland. They will not only create decorative privacy hedges, but also boost real estate value. But as sturdy as these conifers are, sometimes cedars are short lived. Knowing what kills cedar hedges will give you the resources you need to keep them healthy.
At Fraser Valley Cedar, we know you are just as passionate about cedars as we are. That is why we have rounded up some common reasons that your hedges might be dying. Read on to learn what can be impacting the health of your hedges.
Damage During Transporting.
It is no secret that cedars are resilient and strong, but that wasn’t always the case. A young plant’s delicate nature requires special handling, especially during transport. If the bark gets damaged, water and nutrients cannot be transported through the hedge’s vascular system, resulting in its death.
Poor Planting Practices.
Proper planting techniques are vital for healthy cedars. When planting your hedge, try to plant its roots so their flare is level with the surface of the soil. This allows the roots to receive adequate oxygen and warmth. In addition, do not place your cedar too close to other trees, bushes, or vegetation. Otherwise, it will be extremely difficult for your hedges to acquire ample nutrients, water, and sunlight.
Overfertilizing Your Cedars.
An overdose of fertilizer can lead to devastating consequences for your cedar hedges. By overfertilizing your soil, salt deposits accumulate and cause the roots and needles to burn and turn brown. It is not just fertilizer that can destroy your hedges. You can also kill the foliage of your cedar hedges by spraying herbicides near or on them.
Environmental Stressors.
You might be surprised to learn that stress can also negatively impact your hedges. There are various environmental stressors that can critically harm trees, such as flooding, wind, and drought. As a result, your cedars may be more susceptible to disease and pest infestations, such as budworms, spider mites, and other insects. Your hedges can also be adversely affected by air pollution, ground pollution, and extreme temperatures.
The Ever-Dreaded Root Rot.
Cedar roots can also succumb to root rot, which can be fatal. Fungus can grow in the roots of plants when they are overwatered or overly damp. Once mold accumulates on the hedges, it turns them brown and eventually kills the plant. Although this disease is incurable, using fungicides will help control it. Additionally, removing the affected cedar may help prevent further spread.
While cedars can prematurely die, there are steps you can take to prevent it from happening. If you spot browning needles or the onset of root rot, it is important to act quickly to save the hedge before it’s too late. With the proper care and knowledge, your cedars will live a long healthy life.
