Yeah, I have mulch. Still mulch. I like mulch. Preen helps keeping the weeds out of it too.
We have used landscape timber, but we are in the process of getting rid of them. We still have some on the side and front. It's helped alot over the years, but I'm ready for something else. Or yet, nothing at all.
I wanted a clean cut look without the fancy smancy things like brick or scolloped brick edging. Simple and clean. The Boss would only run over them anyway.

My husband hates to go around things. It's bothersome to him...even with a zero turn. Yes, he also uses the weedeater I purchased him. However, he only does it when I mention it and the grass is knee deep around the trees. I'm grinning and I'm sure every other man thinks the same thing!
I love my yard and I like it to look clean and neat. I can't complain much because the Boss is like that too. Especially with his boat. Heh.
