(State) The Iowa Department of Natural Resources says it’s time to stop pruning Oak trees.
John Lorenzen, with the DNR office in Lewis, said they typically suggest people stop pruning Oak trees around March 15th, but the unseasonably warm February has moved up that date.
If a tree is wounded from storm damage or pruning is required during the growing season, treat the wounds immediately with a wound dressing such as acrylic paint. Do not purchase pruning paints/sealants. Those products slow the tree’s ability to seal over the wound.
