Lawnmower and Weed Trimmer Blight: Don’t kill your trees!
The sun is shining, the grass is growing, we are in the middle of mowing season! Beware of mowing and weed trimming near trees. Open wounds are a source for pathogens and entry points for fungal decay. Repeatedly wounding a tree with mowers, weed trimmers, etc. will eventually block the flow of nutrients and water from the roots to the tree. The tree will eventually ‘starve’ from the lack of these nutrients and die.
Tips to avoid permanently injuring trees:
- Avoid using weed trimmers/mowers next to the trunk of the tree. Trimming the grass by hand or simply removing the grass next to the trunk of the tree are simple solutions. If using a chemical to kill the grass, make sure to keep the spray off of the tree. Using cardboard to protect the tree from spray drift is one easy way.
- Place a 3-4” thick ring of mulch around the tree. The larger the mulch ring the better, but recommend at least extending out to the drip line of the tree canopy.
- Install a protective tree wrap around the trunk of the tree to keep mowers and trimmers away. Be sure to check the wrap periodically to make sure that it is not too tight around the trunk or holding excessive moisture.
