Storm Recovery and More Helpful Tips to Maintain Long-Term Tree Health
The epic storm that swept through our region this summer left a lasting impression. Along with damaged homes, vehicles, and crops, many trees and shrubs across the County of Newell were hit hard. Branches were broken, bark was stripped, and entire canopies were shredded by hail and wind. For many residents, the sight of battered trees is discouraging — but the good news is that most healthy trees can recover if we give them the right care.
Trees are resilient. Even when leaves are lost and branches are scarred, roots often remain strong, storing the energy needed for regrowth. But recovery isn’t automatic. How we care for our yards in the months following a storm will determine whether our trees bounce back stronger or decline over time.
To support homeowners and landowners, the County Agricultural Services team has consulted with the experts at ATTS Group and they provided some valuable information that outline the steps you can take right now to care for your hail-damaged trees, watering in fall and winter, and proper mulching.
Caring for Trees After Hail & Storm Damage
Hail is especially hard on trees because it strips away leaves — the energy factories that keep them alive. While some trees may look nearly defoliated, many species have dormant buds that can push out new leaves within weeks. Removal is not always necessary, even when damage appears severe.
If your trees were affected:
- Start with safety. If branches are tangled in power lines, stay clear and contact the utility company.
- Prune carefully. Remove only broken, hanging, or severely damaged branches. Avoid “topping” trees or cutting back healthy growth.
- Call a professional. A certified arborist can assess hazards and safely manage large limbs.
- Be patient. Even heavily damaged trees can recover over time, as long as the root system is healthy.
Fall & Winter Watering
One of the most important — and often overlooked — practices for tree health is deep watering in the fall. As temperatures drop, trees begin to shut down above ground, but their roots continue to function well into winter. Adequate water acts as insulation, protecting roots from freezing air and reducing the risk of dieback.
In our dry Alberta climate, September and October often bring little rainfall. Without supplemental watering, trees can go into winter stressed and come out weaker in spring.
Tips for success:
- Water deeply. Aim for moisture to reach 6–12 inches into the soil.
- Time it right. Water after leaves have fallen but before the ground freezes.
- Focus on the drip line. Water along the outer edge of the tree’s canopy, where most feeder roots are located.
- Avoid overwatering. Saturated soil can suffocate roots. Monitor moisture and adjust for rainfall.
Healthy, hydrated roots are far more resilient against frost, wind, and fluctuating soil temperatures.
Mulching for Year-Round Protection
Mulch might seem simple, but it is one of the most beneficial treatments you can give your trees. By spreading a 4–6 inch layer of organic material (like wood chips) around the base of the tree, you provide multiple benefits:
- Conserves soil moisture and reduces evaporation
- Suppresses weeds and protects against lawnmower damage
- Regulates soil temperature in both hot and cold seasons
- Adds nutrients to the soil as it breaks down
Remember: avoid mulch “volcanoes.” Piling mulch against the trunk can trap moisture and invite pests or disease. Instead, keep it in a “donut” shape, with a clear space around the base of the trunk.
Bringing It All Together
Storm recovery is not about one quick fix. It’s about giving your trees the ongoing support they need — repairing damage, ensuring roots stay healthy through winter, and building resilience for the future. By pruning carefully, watering deeply in the fall, and mulching properly, you can help your trees withstand Alberta’s tough conditions and continue providing shade, shelter, and beauty for years to come.
