Oak Wilt

Winter is the time to get the dead oak branches trimmed and removed.

We live in Oak Wilt territory and are in the highest danger season April, May and June for spreading Oak Wilt. While all species of oak can be affected, oaks in the red oak group (oaks with pointed lobes on their leaves) are by far the most susceptible and are probably the most abundant tree in our yards. Northern red and pin oaks can die within two to three months of infection. White oaks are the most resistant and may survive for years after infection. Bur oaks are intermediate and may die within two to three years of infection.

Emerald Ash Borer

Detail your services

Emerald Ash Borer (EAB) has killed millions of ash trees since 2002.
Minnesota currently has the largest Ash tree population in the United States. 
Don’t move firewood to or from your lake home from long distances.
(You typically can’t see if firewood is infested or not, so why take the risk?)
Emerald Ash Borer is on its destructive path (CLICK HERE FOR KARE 11 STORY) 
It is spreading too!  Now only 6.5 miles east and southeast of Elk River:  (CLICK HERE FOR MAP) 
Early detection is critical to minimizing tree loss and the subsequent loss of environmental benefits.
