Signs of Over-Pruning

When pruning your alder trees, it’s essential to be mindful of potential signs of over-pruning. Here are some indicators to watch out for:

  • Excessive Removal: If you’ve removed a large portion of the tree’s canopy or branches, it could lead to stress and compromise its health.
