It certainly has been chilly in recent weeks, but spring is coming. When the weather warms up, the annual return of spongy moth caterpillars will begin.

The overall spongy moth population is currently low in Wisconsin. However, egg mass numbers may remain high enough to cause nuisance problems and heavy tree defoliation on individual trees or in small areas.

There’s a way for property owners to help keep the population down: Get out now to locate and properly dispose of spongy moth egg masses, which were produced by adult moths last summer. Each spongy moth egg mass contains hundreds of eggs that will hatch into hungry, leaf-eating caterpillars in the spring.

An article in the January edition of the Wisconsin Department of Natural Resources’ Forest Health News contained some incorrect information on the disposal of wreaths, trees, boughs and other holiday decorations.

The article focused on disposing holiday plant matter in ways that avoided the spread of invasive insects, seeds and spores that can spread to harm trees, plants and habitats.

With an April 1 deadline on the horizon, it’s time for eligible Weed Management Groups (WMGs) to consider applying for a Weed Management Area-Private Forest Grant Program (WMA-PFGP) grant to address invasive forest plants in 2026.

The WMA-PFGP helps eligible groups both by dealing directly with the invasives and by providing education, information and outreach to others. The grants are meant as reimbursements that cover up to 75% of eligible costs, with a 25% match required.

When Is The Best Time To Prune Trees?

To best answer the titular question, I like to start by flipping the question on its head: When is the worst time to prune trees?

To answer this reworded question, we first need to acknowledge that “pruning is wounding.” Anytime you cut off a living portion of a tree, you are doing two main things:

  • Removing photosynthetic material.
  • Creating a potential entry point for decay.

Invasive plants and insects don’t mind playing the long game. After all, they’re just trying to survive and thrive, like the rest of us.

They’ll hang out as part of your holiday decorations throughout the season, just on the chance humans might dispose of them improperly, giving them an opportunity to find a new home in your yard or neighborhood.

Trees are good. For those who hold trees in high esteem, this simple statement feels as much a universal truth as the sky being blue or the sun rising in the east. It can feel unfathomable that anyone might hold a contrasting opinion.

Luckily, if you are of the trees are good persuasion, there’s plenty of research out there to support your stance. Oxygen production, air pollutant removal, stormwater reduction and filtration, lower energy bills, increased property values, food sources, recreational opportunities, wildlife habitat and calming aesthetics are just a few oft-touted benefits provided by trees.
