How To Clean Up A Perennial Garden

URBANA — As the days get shorter and cooler, the gardening season starts to wind down, and many of us will begin cleaning up our landscapes for the winter.

While cutting back dead plants and raking leaves can make for a clean-looking yard, it may not be the best thing for pollinators and other wildlife that inhabit our landscapes. So, how should we approach garden clean-up in the fall?

How do pollinators, wildlife overwinter?

While monarchs and some species of birds will migrate south for the winter, most of our pollinators and other wildlife will stick around. Most insects will enter diapause (they stop developing due to unfavorable conditions) during the winter months. Depending on the species, this can be as an egg, larva, pupa, or adult. Regardless of what development stage they spend the winter in, insects will seek out protected locations to spend the winter.

Amphibians will enter go into hibernation (actually brumation) to spend the winter. Some, like salamanders and toads, will burrow into the ground and try to stay below the freeze line. Peepers and wood frogs may also burrow into the soil to overwinter, but not as deeply. They will be subject to freezing temperatures and will produce an "antifreeze" to prevent their cells from freezing, but the rest of their bodies will freeze.

October in Illinois was warm with plenty of rain

What should I do with my leaves?

Fallen leaves can be an excellent place for insects and other wildlife to overwinter. These leaves provide a protected location. Many species of moths and butterflies like swallowtails and luna moths will overwinter in leaves. Bumble bee queens may also utilize leaves to overwinter in.

Fallen leaves can also provide insulation for those animals overwintering in the ground. A good example of this is with spring peepers; if peepers get too cold, they will die. Having a layer of leaves can help protect these frogs and may make a difference in their ability to survive.

Leaves in lawns are commonly raked up and then bagged to be taken away or burned. Instead of getting rid of your leaves, consider leaving at least some of them where they are (it doesn't need to be your entire landscape). Leaving leaves in garden beds or out of the way areas will provide habitat for overwintering animals.

One common concern with fallen leaves is that they will smoother and kill turfgrass. This is certainly true if you have a thick layer of leaves on your lawn. However, if only 10-20percent of your lawn is covered in leaves, they can be left where they are since they are unlikely to smother turf.

Cleaning up perennial, annual plants

Once our perennial plants begin to decline in the fall, many of us will go out and remove flower stalks and dead foliage, giving our landscapes a nice, tidy appearance. While this may be visually appealing to some, it's not the best habitat for wildlife during the winter.

Instead of cutting down dead plant material this fall, wait to remove it until the spring and embrace its beauty this winter. Leaving flower stalks, dead/dried leaves, and grasses stand can add dimension and visual interest to a landscape.

This dead plant material can also be habitat for pollinators and other beneficial insects. Some of these insects may lay their eggs on these plants. Many butterflies will also pupate and spend the winter on these plants as well. By leaving this plant material in the landscape, we can preserve these insects for next year.

What about vegetable gardens?

Vegetable gardens are another area where you want to do a good job with garden clean-up, especially if you've had pest and disease issues. Like beneficial insects, pest insects, like squash bugs, and diseases will overwinter in plant debris. Removing plant debris can help reduce the amount of pest and disease issues you may encounter in your garden next year.

Controlling weeds in vegetable gardens is also a good idea. Winter annual weeds like henbit, common chickweed, and shepherd's purse will germinate in the fall and resume growth in spring. Managing them now may lead to fewer weed problems in the spring, at least until summer annual weeds start germinating.

My Town: Clint Walker's memories of Coles County as pulled from the archives

Cosmic Blue Comics

From the Nov. 22, 1992, Journal Gazette, this photo of Cosmic Blue Comics in Mattoon; where I spent virtually every Saturday afternoon for about two years. That small back room you see just off to the right of the Coca-Cola sign was where they kept the many, and I mean many, long-boxes of back issues. I still own my bagged copy of "Tales of the Beanworld" issue No. 1 that I found back there. Sadly, this location is now just a "greenspace".

Mattoon Arcade

Pictured, Shelbyville's Bob Murray from the June 2, 1982, Journal Gazette, displaying his dominance over the TRON arcade game at the "Carousel Time" arcade at the Cross County Mall, later to be the Aladdin's Castle, soon thereafter to be not a thing anymore. I spent just about every Saturday at that arcade, perhaps with that exact same haircut. No overalls, though. I was more of an "Ocean Pacific" kind of kid.

Icenogle's

Pictured, from the Nov. 28, 1988, Journal Gazette, Icenogle's grocery store. Being from Cooks Mills, we didn't often shop at Icenogle's...but when we did, even as a kid, I knew it was the way a grocery store is supposed to be in a perfect world, and that's not just because they had wood floors, comic books on the magazine rack, or plenty, and I mean plenty, of trading cards in wax packs.

Cooks Mills

I had long since moved away from Cooks Mills by the time this Showcase item about Adam's Groceries ran in the June 13, 1998, Journal Gazette, but there was a time when I very well could have been one of those kids in that photo; for if it was summer, and you had a bike, and you lived in Cooks Mills, that's where you ended up. At last report, they still had Tab in the Pepsi-branded cooler in the back. I'm seriously considering asking my money guy if I could afford to reopen this place.

Mister Music

Pictured, from the July 16, 1987, Journal Gazette, this ad for Mister Music, formerly located in the Cross County Mall. I wasn't buying records at that age, but I would eventually, and that's where it all went down. If you don't think it sounds "cool" to hang out at a record store with your buddies on a Friday night, a piping-hot driver's license fresh in your wallet, you'd be right. But it's the best a geek like me could do. Wherever you are today, owners of Mister Music, please know that a Minutemen album I found in your cheap bin changed my life.

Sound Source Guitar Throw

Portrait of the author as a young man, about to throw a guitar through a target at that year's Sound Source Music Guitar Throwing Contest, from the April 18, 1994, Journal Gazette. Check out my grunge-era hoodie, and yes...look carefully, those are Air Jordans you see on my feet. Addendum: despite what the cutline says, I did not win a guitar.

Pictured, clipped from the online archives at JG-TC.com, a photo from the April 18, 1994, Journal Gazette of Sound Source Music Guitar Throwing Contest winner, and current JG-TC staff writer, Clint Walker.

Vette's

Here today, gone tomorrow, Vette's Teen Club, from the June 20, 1991, Journal Gazette. I wasn't "cool" enough to hang out at Vette's back in it's "heyday," and by "cool enough" I mean, "not proficient enough in parking lot fights." If only I could get a crack at it now.

FutureGen

FutureGen: The end of the beginning, and eventually, the beginning of the end, from the Dec. 19, 2007, JG-TC. I wish I had been paying more attention at the time. I probably should have been reading the newspaper.
