While winter is just beginning to creep in on Wisconsin, many gardeners are already thinking ahead to the next spring planting season. While dreaming of spring blooms and designing your next garden or landscape layout, consider invasive plants that may try to weed their way into your plans.

Many invasive plants that are problematic for Wisconsin forests started as garden ornamentals. Although Wisconsin regulates 145 plants under the invasive species rule NR 40 prohibiting their sale, it’s essential to check your selections before purchasing and choose native plants when possible.

With winter in full swing, many gardeners dream of spring and begin planning what plants to add to their gardens. Now is a great time to brush up on what not to plant to avoid invasive species that might be hiding in plain sight.

Woodlot in fall, most trees have lost their leaves which are covering the ground. Several burning bush shrubs still with their bright red leaves stick out against the brown backdrop.

Have you seen small round holes in acorns? These holes are a sign of acorn weevil damage that can occur in all Wisconsin oak species.

In a pile of brown and tan acorns, two have small round pencil-tip sized holes caused by acorn weevil larvae burrowing out from the inside.

Collecting tree seeds in Wisconsin

By Jeremiah Auer, Wisconsin DNR forest regeneration specialist, (715) 459-1999, Jeremiah.Auer@wisconsin.gov

The Wisconsin state nurseries have been producing seedlings since 1911. In that time, there have been many changes in personnel, growing techniques and distribution methods. However, something that has remained constant is the source of those seedlings: Wisconsin seeds.

The vast majority of seedlings produced at the Wisconsin state nurseries originate from seed collected from native trees. From the tiny, pepper-like seed of aspen to the large, husky black walnut, the DNR reforestation staff at the nurseries collects, cleans and stores hundreds of pounds of more than 30 varieties of native tree and shrub seed every year.

While we are able to satisfy some of our needs, we rely on members of the public to collect for us as well. For those interested in becoming seed collectors, we publish a newsletter every fall. Information on seed collection and the 2018 Seed Collector’s Newsletter can be found on the DNR website.

Our staff is always available to answer questions about seed collection or any other reforestation topic.

So, if you are looking for a fun activity for yourself or your family this fall, why not spend some time helping the Wisconsin reforestation team fill our seed coffers.
