When storms roll in, your trees shouldn’t become airborne hazards. A falling branch can shatter a windscreen, bring down a power line, or crash straight through your roof.
The good news? With a little care and foresight, your trees can stand firm, even in the wildest weather. Whether you’ve got a lone oak in the garden or a small woodland by the fence, prevention is always better than costly clean-up.
The tips below will help you shield your leafy companions and keep your home safe.
Assess Tree Health Regularly
Begin your monthly check at ground level. Try the screwdriver test: push it into the soil around the trunk.
If it slides in too easily, especially when the ground is dry, you might be facing root rot. Healthy trees should be rooted in firm, stable ground.
Next, inspect the trunk. Bark should feel solid and appear unbroken.
Deep, vertical cracks that run into the wood are bad news, while any oozing sap could indicate a bacterial infection. Are there clusters of woodpecker holes? These often point to insect activity beneath the surface.
Monitor the leaning trunks as well. Mark their position and check back each month, as even subtle shifts can suggest an unstable root system.
As for the canopy, look for crossing or crowded limbs.
When branches rub against one another in the wind, the bark wears away, leaving the tree vulnerable to disease. Also watch for shoots sprouting from old cuts, which is often a sign of stress.
The ideal time to inspect is just before sunrise. In the early light, leaves droop slightly, making it easier to study the branch structure and spot hidden issues. Catch problems early, and you’ll spare yourself a great deal of trouble when storms strike.
Prune Trees Before Storm Season
Pruning is one of the best ways to build a stronger, storm-ready tree.
Start about three months before storm season begins to give any cuts enough time to heal and strengthen the structure.
Deadwood and any limbs that cross and chafe should be removed first.
Locate the branch collars—the swollen bit where a branch meets the trunk—and cut just beyond them, at a slight angle. Avoid flush cuts or leftover stubs, as these wounds can invite decay.
Stick to branches under 12 cm in diameter unless you’re working with a certified arborist.
As a general rule, don’t remove more than a quarter of the tree’s live branches in one go. Prioritise those that hang over walkways or lean towards buildings.
Install Support Systems for Weak Trees
Some trees need a helping hand. Done properly, support systems can bolster weak limbs and prevent storm damage.
Dynamic cabling is one such option. Flexible steel lines enable branches to move naturally without snapping in strong winds. These are usually installed high up, connecting at-risk branches to stronger ones nearby.
For trunks that fork awkwardly or show signs of splitting, through-bolts with washers can add internal strength without harming the tree.
Lower down, rigid braces can be better. These rods are fixed beneath weak branches to help distribute weight more evenly and reduce the risk of failure.
Keep in mind that these solutions are not a substitute for removing severely hazardous limbs. Still, they can give struggling but otherwise healthy trees a fighting chance.
Annual inspections are a must—cables can loosen, and materials wear over time.
Create a Windbreak with Strategic Planting
A good windbreak acts like a buffer, reducing wind speed and shielding more delicate trees behind it.
Plant in a U-shape, facing into the prevailing wind.
Use three rows for best effect—tall evergreens like Norway spruce in the middle, flanked by shorter native species on either side. Space them around 2.5 metres apart to form a dense but breathable barrier.
Each row should be about 3 metres from the next. This configuration encourages wind to lift up and over the landscape, instead of tearing through it.
When planning placement, consider how tall your trees will grow. Measure their mature height and double it—that’s the minimum distance to keep from buildings.
For instance, a spruce expected to reach 20 metres should be planted at least 40 metres from your house.
Always pick species suited to your soil, light, and climate. A slightly shorter tree that thrives will offer better protection than one that struggles.
Mulch and Water Trees Properly
Healthy roots are the foundation of storm resilience.
Water deeply but infrequently to encourage stronger root development, and during winter, water on mild days when the soil isn’t frozen to help prevent winter burn.
Apply a mulch cover around the base of each tree, roughly 8 cm thick. Let it stretch outwards in a circle, but don’t let it touch the trunk. This process keeps roots moist while stopping rot at the base.
The simple layer serves a dual purpose: locking in moisture while also regulating soil temperature. It’s one of the most straightforward and effective defences you can offer.
Install Drainage Systems
Simply put, excess water weakens roots.
To test your soil’s drainage, dig a hole about 30 cm deep and fill it with water. If the water remains after two hours, you’ve got drainage issues.
French drains are a reliable fix, using gravel-filled trenches with buried pipes that redirect water away from root zones.
Dig these close to affected trees and ensure a slight downward slope toward an existing drain or dedicated water-collection area.
For areas with heavy clay soil, you should also consider adding organic matter to improve long-term permeability.
Use Wraps and Supports for Young Trees
Young trees are especially vulnerable. In their first couple of winters, wrap their trunks in breathable material to fend off frost and nibbling animals. Cover from ground level to the lowest branches.
In addition, staking can help. Use two stakes placed opposite each other, outside the root zone. Secure the tree with soft ties. Old bicycle tubing can serve as an alternative.
Generally, remove stakes after the first growing season. However, in loose or sandy soil, you’ll need to wait for a second season to ensure proper anchoring.
Invest in Expert Services
When in doubt, bring in a tree care professional with experience in tree trimming and storm preparation.
They can identify structural issues you might miss and offer tailored advice based on species, soil type, and surrounding structures.
A specialist can also help you navigate local tree protection laws, ensuring that any trimming or removal is fully compliant. If you live in a conservation area or have protected trees, this step is essential.
In addition, many services offer tree risk assessments and can advise on how to improve wind resistance without harming local wildlife or damaging habitats. Some also provide inventory reports for larger properties to track ongoing tree health.
Before hiring, ask for proof of insurance and a clear care plan for each tree on your property.
Conclusion
Protecting your trees isn’t just about preventing catastrophe. It’s about nurturing a resilient landscape you can enjoy year-round.
A watchful eye, timely trimming, and a bit of mulch can go a long way.
So pull on your gloves, grab your shears, and show your trees the care they deserve. You can make them resilient in the face of any weather by exerting a little effort.
