Now that spring has sprung, Wisconsin Department of Natural Resources (DNR) staffers can expect questions from the public about their yard trees.

However, the mission of DNR Foresters and Forest Health staff is geared toward focusing on larger, forested areas, not yard trees. Those questions fall under the purview of the University of Wisconsin-Madison Extension Horticulture Program.

The NR40-restricted invasive plant garlic mustard (Alliaria petiolata) is prevalent in many Wisconsin woodlands, but a new wave of hope is on the horizon.

The garlic mustard aphid, a tiny, dark, gray-to-green insect sometimes called the “grenade” aphid after the pattern of raised blotches on its back, was found in 2021 at the Holden Arboretum in Ohio. It could become a viable form of biocontrol for the garlic mustard plant.

The treatment sites contain high-value trees at six state parks or forests in Columbia, Marinette, Sauk and Walworth counties. A total of 928 acres will be treated with an aerial spray of “Foray” bacterial insecticide containing Bacillus thuringiensis var. kurstaki.

Watch For Hemlock Woolly Adelgid

Landowners with hemlock and anyone who walks through or works in hemlock stands can help watch for signs of hemlock woolly adelgid (HWA).

This invasive insect has not yet been identified in Wisconsin, but it has been found in seven counties in Michigan’s Lower Peninsula. The insect sucks the sap of hemlock trees, and large populations can cause the decline and mortality of hemlock over 4 to 10 years, depending on the health of the tree and population levels of HWA. It’s vital to find infestations as early as possible to allow multiple options for control and management.

Slime Mold: Mysterious And Amazing

What can learn new things, move toward and acquire food, remember where food was and what foods are preferred, figure out the shortest route through a maze, remember where it has traveled and seem to disappear as quickly as it first appeared?

It’s slime mold, of course!

These easy-to-grow, sweet-sounding, small blue flowers may seem appealing, but you should forget about forget-me-nots. A garden plant frequently found in mixed bouquets, forget-me-nots can easily escape the confines of a garden and spread aggressively.

There are two species regulated as invasives in Wisconsin: an Aquatic forget-me-not (Myosotis scorpiodes) and Woodland forget-me-not (Myosotis sylvatica). Both species are restricted under Wisconsin’s Invasive Species Rule NR40, so control is encouraged if they are found on your property. These species cannot be transferred, transported or introduced without a permit.

Both the aquatic and woodland species of forget-me-not bloom in early spring and can share many visual characteristics. Continue reading “Forget About Planting Forget-me-nots”

Though it is impossible to know precisely when they emerge, there is a tool that can be used to help you ease your anxiety a bit.
