I was wondering what you use in your outdoor bog gardens to keep those pesky little weeds from growing? I have one mini bog with pea gravel on the top, and it works well. I only have Sarrs in that one. But when thinking on a bigger scale, it can get costly.
So, I have a 10 lbs bag of hazelnut shells I use for regular gardening, would they work for a bog or mini bog if there was only Sarrs in it?
What other coverings have you used? What works best and have you tried anything that didn't work?
Thank you all!!
