Don’t Start Yard Cleanup in Spring Too Soon—Here’s Why

As the weather warms and the rst green shoots appear a er the winter, many gardeners are eager to start tidying up their yard. Yet, starting yard cleanup too soon can do more harm than good. at’s because our yards are important habitats for a wide range of bene cial insects that play a key role in maintaining the health of our garden plants.

Bees, butter ies, and moths pollinate our owers, leading to increased production of fruits, vegetables, and seeds. Lady beetles, re ies, and wasps prey upon and control common garden pests, such as aphids and grubs. With the help of bene cial insects like these, gardeners can reduce their use of chemical pesticides. is not only saves money, but also protects the health of people, pets, and the environment.

With this in mind, here’s what experts recommend when it comes to timing your yard cleanup in spring.

Why to Delay Yard Cleanup

While dried leaves and stems may seem unsightly, they’re essential habitat for many bene cial insects. For example, bumble bee queens, re y larvae, and some species of lady beetles and wasps overwinter in leaf litter. Luna moth caterpillars spin cocoons from leaves and spend the winter among fallen leaves. Swallowtail butter ies overwinter in chrysalids that are o en attached to dried plant stems. Additionally, many native bees, some as tiny as a grain of rice, hibernate within plant stems. ese insects only emerge from their winter naps when temperatures warm up to a certain point.

“ e goal of delaying [spring cleanup] is to help the life cycles of all these critters,” says Elizabeth Braatz, an insect ecologist at the Wisconsin Department of Natural Resources.

People o en start yard cleanup too early in spring, says Clay Bolt, Manager of Pollinator Conservation for World Wildlife FundUS. He points out that despite warm, sunny days, low nighttime temperatures can be dangerous for emerging insects, causing many to stay dormant for longer than you’d think. By cleaning up your spring garden too early, you may be discarding these vital insects along with the plant debris.

“As part of tidying, we may want to remove all that debris away but basically you’re carting away your native pollinators in the process,” explains Bolt.

When to Start Spring Yard Cleanup

It’s tricky to pinpoint the exact date to begin yard and garden cleanup in spring because insects emerge from hibernation at di erent times. ose times also vary depending on the climate zone you live in.

“What I like to say to people is, if you walk outside at night and you’re comfortable, then it’s probably okay to clean up,” says Bolt. e Xerces Society for Invertebrate Conservation also suggests waiting until it’s time to plant tomatoes, apple and pear trees have nished blooming, or your grass has grown enough to justify mowing.

Leave Some Leaves and Stems

Since it’s di cult to pinpoint when bene cial insects will wake from hibernation, experts recommend leaving at least some leaves and stems in your garden during yard cleanup. is prevents unintentional disposal of sleeping insects and ensures they have habitat throughout the summer.

“We o en think about feeding the pollinators,” says Braatz, but “they also need shelter as well as food.” is may be especially important for native bees, which are facing unprecedented declines. “ ere is this idea that all bees nest in colonies, but over 90% of native bees in the world are solitary and mostly nest in the ground, o entimes in bare dirt or beneath mulch, leaves, or rotting logs,” Bolt says.

e more leaves you can leave in your garden beds, the better, says Braatz. If you have too many leaves, redistribute some to other areas of your yard. is approach o ers a signi cant perk: free mulch! Leaves not only suppress weeds and retain soil moisture, but are also more environmentally friendly than bark mulch or landscape fabric. “Leaf litter is just a really, really wonderful resource,” says Braatz.

When it comes to stems, “don’t scalp everything down to the ground,” says Bolt. Either leave stems intact in your garden beds or trim them down to a height of 8-24 inches. en, scatter any stem trimmings around your garden or gather them into bundles and place them in a corner of your yard or under large bushes. Dried stems provide nesting sites for native bees, so you’re essentially creating natural bee hotels. Also, don’t worry about old stems looking unattractive; as your plants grow, they will naturally conceal them.
