Help! Deer ate my Evergreens - Will They Grow Back?
If you've stepped outside and found your cedars and pines stripped bare by deer, you're not alone. Driving around Swift Current the last couple weeks, I've noticed many cedars and pines stripped of their needles and foliage by the deer that have been wandering around town all winter. I thought I'd provide a little guidance on how much damage is too much when it comes to your evergreens and the browsing they've been subjected to this winter.
Understanding the Damage
Deer damage varies depending on the species of tree and how severely it was browsed:
Cedars (Thuja spp.) – Cedars are a favourite snack for deer, especially in winter (and very noticeably this winter). Unfortunately, if a cedar has been eaten down to the inner brown wood, it likely won’t regenerate from that area. Cedars only produce new growth from their green outer layer, so if deer have stripped it down too far, you may need to replace it.
Pines (Pinus spp.) – Pines can tolerate some browsing, but if the central leader (the main upward-growing branch) has been eaten, the tree may struggle to develop a proper shape. However, they can often recover if new buds remain intact.
Will They Grow Back?
Light Browsing: If deer have only nibbled the outermost foliage, your trees will likely push out new growth in spring.
Moderate Browsing: If some branches were stripped but not completely destroyed, the tree may recover over time, but it could take several years to regain its former fullness.
Severe Browsing: If trees have been eaten down to bare stems with no green growth left, recovery is unlikely, especially for cedars. Pines have a better chance of bouncing back if some buds remain.
How to Help Your Trees Recover
1. Prune Damaged Areas – Trim broken or chewed-off branches back to a healthy growing point. This encourages new growth and prevents disease from setting in.
2. Fertilize Wisely – In early spring, apply a slow-release, balanced fertilizer (such as 10-10-10) to support regrowth. Avoid excessive nitrogen, as it can encourage weak, leggy growth.
3. Mulch for Moisture – A layer of mulch around the base will help retain moisture and reduce stress as the tree recovers. Keep mulch a few inches away from the trunk to prevent rot.
4. Provide Water – If we have a dry spring or summer, ensure the trees receive deep, consistent watering to support regrowth.
5. Protect from Future Damage – If deer have found a food source, they’ll return. Prevent further damage with:
Physical Barriers: Wrap trees in burlap or install fencing during winter. A 6-8 foot fence is best for keeping deer out.
Deer Repellents: Spray trees with commercial deer repellents such as Plantskydd or use homemade solutions like eggs and garlic. Reapply after rain or snowfall.
Alternative Plantings: Surround your most vulnerable trees with deer-resistant plants such as junipers, spruce, or ornamental grasses. While not 100% foolproof, they may deter browsing.
When to Replace Your Trees
If your cedars have been stripped to brown sticks or your pines have lost their central leader and most of their buds, it may be time to replant. Consider choosing more deer-resistant options like:
Colorado Blue Spruce (Picea pungens) – Deer tend to avoid their prickly needles.
Junipers (Juniperus spp.) – Hardy and unappetizing to deer.
Black Hills Spruce (Picea glauca 'Densata') – A dense, slow-growing spruce with excellent winter interest.
If you're looking at replacing your trees, reach out now and we will have a better chance of finding you what you need.
Deer damage can be disheartening, but your trees might recover with time and proper care. Protect them going forward to prevent more setbacks, and if necessary, consider replanting with deer-resistant varieties.
