The right time to prepare your trees for storm season in Michiana is before the first storm, not after. Northern Indiana and Southwest Michigan sit in a weather corridor that produces some of the most tree-damaging storm events in the Midwest: summer derechos with straight-line winds over 70 mph, spring ice storms that can add hundreds of pounds of weight to a single branch, and late-season lake-effect events that hit when trees still have a full canopy.
A proactive inspection and some targeted pruning in late winter or early spring can mean the difference between riding out a storm without incident and spending the next day calling for emergency tree service. Here is the complete checklist we use when evaluating trees for storm readiness across our South Bend, Elkhart, and Mishawaka service area.
Start With a Full Property Walk
Walk your entire property and look at every significant tree. Do this in late winter when trees are bare and structure is fully visible. You are looking for anything that has changed since the last time you really paid attention, including new leans, dead zones in the canopy, cracks in the trunk or major branch unions, and any trees that have grown significantly closer to structures.
Take photos of anything that concerns you. This gives you a reference point and is useful if you end up consulting an arborist or filing an insurance claim later.
Do not skip this step: Most homeowners only look at their trees when something is obviously wrong. A pre-storm walk when everything looks fine is what catches the slow-developing problems before they become emergencies.
The Storm Prep Checklist: What to Look For
- Deadwood in the upper canopy, especially large branches over 2 inches in diameter
- V-shaped branch unions with included bark, which are structurally weak and fail under load
- Co-dominant stems, two main trunks of similar size splitting from a single point
- Cracks or splits in the trunk or at major branch attachments
- Canopy imbalance with significantly more weight on one side than the other
- Trees leaning toward the house, garage, or power lines
- Fungal growth on the trunk or at the base
- Cavities or hollows in the trunk
- Root zone disturbance from recent construction or landscaping
- Trees with less than 12 inches of clearance from your roofline
If you spot any of these during your walk, a professional tree assessment can tell you exactly what you are dealing with and what work is actually necessary before storm season arrives.

The Specific Storm Risks in Northern Indiana
Not all storm risks are the same. Michiana faces three distinct storm types that damage trees in different ways, and understanding each helps you prioritize your pre-season work.
Summer Derechos and Straight-Line Wind Events
Derechos are fast-moving windstorm complexes that can produce sustained winds over 60 mph and gusts over 80 mph across a wide path. St. Joseph and Elkhart Counties have been hit by multiple significant derechos in the past decade. These storms exploit structural weaknesses in trees instantly. Co-dominant stems split, included bark unions fail, and shallow-rooted trees uproot entirely.
Crown thinning before storm season directly reduces the wind-sail effect on tree canopies. A properly thinned canopy lets wind pass through rather than catching it like a sail. Our trimming and pruning service includes crown thinning as part of every structural assessment.
Ice Storms
Ice accumulation is one of the most destructive forces a tree can face. A single inch of ice coating adds approximately 500 pounds of additional weight per inch of branch diameter. Multi-day ice events in Northern Indiana regularly produce accumulations of half an inch to a full inch, which is enough to break major limbs from otherwise healthy trees.
“A single inch of ice coating can add 500 pounds of weight per inch of branch diameter. That is why even healthy trees fail in Michiana ice storms.”
Deadwood removal before ice season is the single most important thing you can do. Dead branches are brittle and fail under ice loads that living wood would handle without issue. If you have significant deadwood and are heading into fall, do not wait.
Wet Spring Snowstorms
Northern Indiana regularly gets heavy wet snow events in March and April, sometimes after trees have already begun leafing out. A tree with a partial leaf canopy catches wet snow and the weight can easily exceed what the branch structure was designed to handle. Trees in Granger, Goshen, and the more rural Michiana townships that have not been pruned in years are particularly vulnerable to this kind of event.
April snow with early leaf-out is particularly dangerous: If you see a heavy wet snow coming in the forecast and your trees have started to leaf out, there is nothing to do but wait it out. The time to reduce that risk was in late winter before growth began. That is exactly why pre-season prep timing matters.
What Proactive Pruning Actually Accomplishes
Deadwood removal eliminates the branches most likely to fail under any storm load. Dead branches cannot flex the way living wood does, and they have no resistance to ice accumulation or wind loading.
Crown thinning opens up the canopy so wind passes through rather than pushing the entire tree. This is especially valuable for large oaks, maples, and cottonwoods with dense canopies in exposed yard positions.
Structural pruning addresses co-dominant stems and included bark unions before they fail. In some cases, cables can also be installed in trees with structural weaknesses to provide additional support without full tree removal.
Clearance pruning removes branches that overhang the roof, touch the house, or are within striking distance of windows, HVAC equipment, or vehicles. For properties in Niles, Edwardsburg, and other areas with large mature tree canopies, this work pays for itself after the first significant storm.
When to Call a Professional vs. Handle It Yourself
Removing small deadwood under 10 feet with a pole pruner is reasonable DIY work if you are comfortable doing it safely. Any pruning that requires a ladder, involves branches over your home, or requires cuts over 2 inches in diameter should be handled by a professional. The risk of injury from a falling branch vastly outweighs the cost savings.
A professional tree service also has the training to identify structural defects that are not visible to an untrained eye, including internal decay, root problems, and branch union defects that can cause failure even when a tree looks healthy from the ground.
Get Ahead of Storm Season This Year
The best window to prepare your trees for Michiana storm season is late February through mid-April. That timing captures the late-winter dormancy window for most species, addresses deadwood before spring growth begins, and gets the work done before the first significant storm system of the year typically arrives.
