Derek,
Your yard sounds a lot like ours. Also a half acre. Also, comprised mostly of weeds.
Granted, mowing is about the only thing we do by way of maintenance.
I've never felt the need to have a perfect lawn. Most lawns in our neighborhood are pretty close to perfect though.
Ours is presentable if you're just passing by. Especially when it's freshly mowed. At least the weeds are green.
Clover is a big presence in our yard. This year, for the first time, I've actually avoided mowing most of the side lot. It's not easily seen from the road. And, when I tried to mow it, it was absolutely teeming with honeybees.
Since we're huge fans of the little yellow guys, I won't hit them with the mower. Then, even when they're gone in the late afternoon, I didn't have the heart to destroy all their flowers.
So, one section of our yard is a little meadow of white flowers; full of happy little honeybees.
I know this does absolutely nothing to answer your question. I apologize for that.
But, your yard sounded so much like ours, you just inspired me to share my story.
Thanks for reading. I hope someone enjoyed it!
Barry
