How To Save A Dying Aspen Tree?

Aspen trees are known for their beautiful white bark and vibrant foliage in the fall. However, these trees can become sickly and start to decline over time. If you have noticed that your aspen tree is dying, there are several steps you can take to try to save it. In this blog post, we will discuss how to save a dying aspen tree.

How To Save A Dying Aspen Tree?

Step 1: Identify The Problem

The first step in saving a dying aspen tree is to identify the problem. Common issues that can cause aspen trees to decline include pests, disease, drought, and poor soil quality. Look for signs of damage or stress, such as yellowing leaves, wilting branches, or insect infestations.

Step 2: Address The Underlying Issue

Once you have identified the problem, take steps to address it. If the issue is pest-related, treat the tree with an appropriate insecticide. If the tree is suffering from a disease, consult with a professional arborist or tree care specialist to determine the best course of action. If the problem is related to poor soil quality or drought, consider adding fertilizer or watering the tree more frequently.

Step 3: Prune Dead Or Damaged Branches

If there are dead or damaged branches on your aspen tree, it is important to prune them. Dead or damaged branches can attract pests and disease, and they can also prevent healthy growth from occurring. Use pruning shears to remove any dead or damaged branches, making sure to cut just above the branch collar.

Step 4: Mulch Around The Base Of The Tree

Adding mulch around the base of your aspen tree can help to improve soil quality and retain moisture. Spread a layer of mulch around the base of the tree, making sure to leave a small gap between the mulch and the tree trunk.

Step 5: Water The Tree Regularly

Aspen trees require regular watering to stay healthy. During dry periods, make sure to water your tree deeply once a week. Avoid watering the tree too frequently, as this can lead to root rot and other issues.

How Can You Tell If An Aspen Tree Is Dying?

You can scratch a piece of bark off a small branch with a knife or thumbnail. If it is green, the tissue is live. If it is brown, the tissue is dead. But understand that just because there is ‘live tissue’ doesn’t mean the tree is ‘healthy’.

Should You Cut Dead Branches Off Aspen?

Quaking aspen must be pruned after heavy winter snowfalls have damaged limbs. The damaged limbs should be pruned back to the collar. Dead or diseased branches should be pruned off whenever you spot them.

What Kills Aspen Trees?

The right way to remove aspen is to kill the tree and the root system with an herbicide and cut it down after it is dead. To kill aspens apply the herbicide Roundup to the base of the trunk. Drill a series of holes into the trunk at a 45-degree angle and fill the holes with concentrated herbicide.

Can You Over Water Aspen Trees?

Aspen isn’t a drought-tolerant tree so watering regularly is a must. However, they can be overwatered just like everything else.


In conclusion, saving a dying aspen tree requires identifying the underlying problem and taking steps to address it. By following the steps outlined in this blog post, you can help to revive your aspen tree and promote healthy growth. If the tree continues to decline despite your efforts, consider consulting with a professional tree care specialist for further assistance.
