Leaf Mulch Sales

Olbrich Botanical Gardens is suspending the sale of leaf mulch. The Wisconsin Department of Natural Resources (DNR) has recommended that leaves not be spread through Dane County due to the possibility of spreading invasive jumping worms.

The DNR has identified that invasive jumping worms are increasing in Wisconsin, including in Dane County and we are committed to reducing the spread of this invasive species.

Jumping worm cocoons have been found to survive the winter in Wisconsin and can be spread through soil, compost, and mulch (hardwood and leaf).

This decision to suspend our leaf mulch sales was made with significant input from the Wisconsin DNR, the City of Madison, and other invasive species experts.

Olbrich Botanical Gardens is committed to sustainable gardening methods and following the best practices of invasive species management as outlined by the Wisconsin DNR.
