When mowing or bush hogging a field, only do approximately 1/2 to 1/3 of the field each year. This creates a more complex and multiple-aged habitat which benefits both wildlife and pollinators.
For example, many of our butterflies will overwinter as a chrysalis attached to grass or flower stalks. Several of our native bees will lay eggs in the hollow stalks of last year’s dead plant stems. Praying mantises overwinter as egg cases attached to plant stems. If you cut the entire field every year, then there is no place for animals like these to overwinter. If you only cut part of the field each year on a rotating basis, then at least part of the field can still provide winter habitat for butterflies, stem-nesting native bees, praying mantises, and other insects.
Wildlife such as songbirds, rabbits, and small mammals can also benefit from a partial mowing pattern. The unmowed parts of the field will provide seed heads throughout the winter plus cover to hide from predators. The next spring, these areas will continue to provide thicker areas in which to hide or raise young, while the mowed areas provide a flush of new growth and easily digestible vegetation.
Only mowing or bush hogging part of a field each year might not look as neat or uniform as fields mowed in the traditional manner, but the critters will thank you for it.

I have miner bees nesting in dirt under house. Go in through one spot. How can I discourage them from coming back once emerge next spring? I live in MD
Hi Mimi,
Thanks for reaching out to me. My first question is, “Why do you want to discourage them from coming back?”
Their tunnels aren’t extensive enough for them to cause any damage to the house or its foundation.
If they are true mining bees and not yellow jackets, then they aren’t aggressive and will just fly out of the way if someone accidentally steps on the entrances to their nests, drops a ball on it, etc.
If they are yellow jackets, then that’s a completely different story and I would NEVER recommend leaving a yellow jacket nest next to the house – too much chance for a bad encounter just because of their social nature.
If they are yellow jackets, talk to your local Extension Office about the best way to get rid of them in your area.
If they are mining bees, and you REALLY, REALLY don’t want them re-nesting there, then once you start seeing them going back in next year try covering that area up with gravel or mulch. That’s the first thing I would try, but mining bees are so interesting to watch and so docile that I would encourage you to think about possibly letting them continue to nest there instead of discouraging them.
I hope that helps,
Shannon
