Winter is the time to control buckthorn

Buckthorn is a shrub or small tree growing up to 20-25' tall and left unchecked invades forests, woodlands, oak savannas, and prairies. (Click on the listing for common buckthorn on our Invasives Species list for more information). The best time to eradicate buckthorn is in the late fall and winter. Here's what to do if you have buckthorn on your property.

• Remove your largest, berry-filled plants first.
• For trunks over six inches wide, cut the trunk and immediately swab the stump with trichlopyr herbicide and oil. (Stop when the spring thaw begins.)
• For smaller trunks, skip the cutting and spray the base of a dry, frost-free trunk with trichlopyr and oil.

Tordon RTU, is pre-mixed trichlopyr with oil. Be sure to read and follow label directions. See our Products and Services page to find where to purchase Tordon RTU.
