If you aren’t sure what you’re doing, be very careful when cutting mature tree roots (roots larger than 2 inches). Root cutting and pruning can affect both a tree’s stability and its ability to nourish itself. Issues during root cutting can result in damage or injury. 

It’s recommended you call in a pro to help, unless it’s a very small tree and you aren’t worried about the prospect of losing the tree.

Late winter is ideal, but if you’re pruning apple trees in the spring, prune them as early as possible in the season. You want to ensure your tree is just creeping out of dormancy and hasn’t started pushing out new growth. If you prune your tree too late into spring, you generally won’t see results until the following year.

That said, there’s no pruning season for unhealthy growth. Remove dead, dying, or diseased branches as soon as you notice them, regardless of the time of year.

If you’re looking to rot a tree stump fast, potassium nitrate will work far quicker than copper nails. First, drill several holes into the stump using a power drill, then pour potassium nitrate pellets into the holes. Next, add water to help the chemical absorb into the wood, thoroughly soaking the stump to ensure the pellets dissolve and spread evenly. Afterward, cover the stump with a tarp to retain moisture and block sunlight, then place mulch on top to secure it in place.

Surface-level tree roots might only pose a small threat, such as being a tripping hazard or obstacle when you mow your lawn. But if mature tree roots start growing in the direction of your home’s foundation or plumbing system, it could be a real problem. Cutting small tree roots out before they grow too large can keep your home safe without removing the whole tree.
