How to Protect Your Trees From Winter Storm Damage in Minnesota

Minnesota winters can be rough on trees. Between heavy snow, freezing rain, and strong winds, it doesn't take much for a weak branch to come crashing down. And when that branch is hanging over your driveway, roof, or garage, you've suddenly got a much bigger problem than a messy yard.

Here in Hastings and throughout Dakota County, we see plenty of trees that could have benefited from a little attention before winter arrived. Sometimes it's a dead limb that's been hanging around for years. Other times it's a large tree with a weak branch connection that finally gives way under the weight of ice.

You can't prevent every bit of storm damage, but you can reduce the chances of having a serious problem. The key is knowing what to look for and taking care of it before the weather turns ugly.

Why Snow and Ice Cause So Much Tree Damage

A few inches of snow usually aren't a big deal for a healthy tree. The trouble starts when that snow is especially wet and heavy, or when freezing rain coats the branches with ice.

Evergreens can be particularly vulnerable because their needles catch and hold snow.

Large, spreading branches on deciduous trees can also collect enough weight to bend or break, especially if they already have cracks or weak connections.

Wind makes things worse. A tree that's carrying a heavy load of ice doesn't move the same way it normally would. Add a strong gust, and branches that have held up for decades can suddenly fail.

Of course, not every tree that breaks during a storm was unhealthy. Severe weather can damage perfectly healthy trees, too. But trees with existing structural problems are more likely to suffer serious damage.

Some Trees Need More Attention Than Others

If you've got mature trees around your property, it's worth knowing which ones may be more vulnerable when winter storms roll through.

Silver maples, cottonwoods, box elders, and willows are common around this part of Minnesota. They're fast-growing trees, but they can develop weak branch attachments and are more prone to breakage than some other species.

Ash trees are another concern, particularly those affected by emerald ash borer. The pest has caused extensive damage throughout the region, leaving many ash trees dead or declining. As these trees deteriorate, their branches become increasingly hazardous.

Then there are trees that have developed structural problems over time, regardless of species.

A large branch with a visible crack, two trunks growing tightly together, or a tree that's started leaning noticeably can all be warning signs. You should also pay attention to dead limbs hanging over your home or driveway.

That doesn't automatically mean the tree needs to be removed. Many problems can be addressed through proper pruning or other tree care. But it's much better to find out before a heavy snowstorm puts those weaknesses to the test.

Take a Walk Around Your Yard Before Winter

You don't need to be an arborist to spot some of the more obvious problems.

Once the leaves have fallen, take a few minutes to look at the trees around your house. Without the foliage in the way, it's easier to see the shape of the branches and identify anything unusual.

Look for dead limbs, cracks where large branches meet the trunk, or branches that seem to be hanging lower than they used to. Mushrooms growing around the base of a tree can sometimes indicate decay, although not every mushroom is a sign of trouble.

Pay particular attention to trees near your house, garage, driveway, or other areas where people spend time.

If something looks questionable, take a picture and have a tree care professional evaluate it. A small problem today could become a much more expensive one after a January ice storm.

A Few Things You Can Do to Help Your Trees

Not every part of winter tree preparation requires professional equipment.

Young trees and evergreens, for example, benefit from having enough moisture before the ground freezes. Minnesota can experience dry fall weather, and evergreens continue losing moisture through their needles during winter.

If the soil is dry, give these trees a good, deep watering before freeze-up. There's no need to water already saturated ground.

Mulch can help, too. A layer about two to four inches deep around the base of a tree helps protect the roots and retain moisture. Just don't pile it directly against the trunk. Leave a little space so moisture doesn't get trapped against the bark.

It's also a good time to clean up fallen branches and other debris around the yard. That won't stop a storm from damaging your trees, but it makes your property easier to maintain once snow starts accumulating.

One thing we wouldn't recommend is trying to remove large dead branches yourself. Even a branch that looks manageable from the ground can be surprisingly heavy, and cutting it incorrectly can cause it to fall in an unexpected direction.

Should You Prune Your Trees Before Winter?

In many cases, yes.

Proper pruning can make a real difference, especially for trees with dead branches, weak limbs, or growth that's getting too close to buildings.

The important thing is to prune with a purpose.

Removing dead or damaged wood can reduce the risk of branches falling during a storm. Selective pruning can also address certain structural weaknesses before they become more serious.

But cutting back a tree too aggressively can create problems of its own. Topping a tree, for example, often encourages weak new growth and can leave the tree more vulnerable down the road.

It's also worth remembering that winter itself can be a good time for pruning.

In Minnesota, oak trees are generally best pruned during the dormant season, when the insects responsible for spreading oak wilt are inactive. If you have mature oaks that need attention, scheduling work during the colder months is often a smart choice.

For larger trees, especially those close to your home or power lines, professional pruning is the safer option.

What About Trees That Are Already in Bad Shape?

Sometimes a tree is simply too far gone for pruning to solve the problem.

A dead tree near your house, a trunk with extensive decay, or a tree with serious structural damage may need to be removed.

That doesn't mean every leaning tree or hollow trunk is an emergency. Some trees live for many years with defects that can be managed. The important question is whether the tree presents an unacceptable risk to people or property.

An experienced tree care professional can evaluate its condition and help determine whether pruning, monitoring, or removal makes the most sense.

And while nobody likes paying to remove a mature tree, dealing with a dangerous one before winter is usually preferable to dealing with it after it falls on something valuable.

What to Do When a Winter Storm Damages a Tree

Even with good preparation, winter storms can still cause damage.

If a large branch comes down, the first thing to do is make sure everyone stays clear of it. Broken limbs can remain caught in the canopy, and damaged trees may have other branches that are ready to fall.

Never approach a tree that's touching a power line. Keep your distance and contact your utility company.

You should also avoid trying to pull down hanging branches or cut limbs that are bent under pressure. Wood under tension can move suddenly when it's cut, creating a serious risk of injury.

For smaller branches that have fallen safely to the ground, cleanup may be straightforward. But when you're dealing with large limbs, damaged trunks, or anything near a structure, it's best to bring in a professional crew.

Get Your Trees Ready Before the Snow Arrives

The best time to deal with a questionable tree is before it becomes an emergency.

Maybe you've noticed a large dead branch over the driveway. Maybe an old ash tree has been looking worse every year. Or perhaps you just haven't had your mature trees inspected in a long time.

Whatever the situation, fall is a good opportunity to take care of potential problems and get ahead of the winter weather.
