How to dispose of ash tree waste

The Emerald Ash Borer (EAB) is smaller than a quarter but can cause big problems for ash trees.

The best time to prune or cut an ash tree is October through April when the insects are dormant. Be extra cautious when pruning or removing diseased wood. All ash tree wood must be disposed of properly. Hennepin County is quarantined for EAB. For Bloomington residents, that means taking the wood to the closest appropriate facility.

Symptoms of infested ash trees include woodpecker holes from where the birds feed on larvae, cracked bark caused by tunneling larvae and distinctive patterns of S-shaped galleries just under the tree’s bark.
