I must be spoiled with fresh potting mix each year... I don't think I've ever pulled a weed out of any of my 40 containers ever.
If I can keep a big enough spot cleared behind the garage, I'll try it for next season in at least a few of the planters. I don't want to be stuck with 40 duds like that one year I tried to re-use the potting mix
... 2 I can just replant if need be.
The biggest problem is going to be keeping the grape vine out. There's new neighbors on the side it comes from, and I think they're going to try to rip it all out. Maybe I should work on killing off the grape vine like the invasive trumpet honeysuckle that I fight yearly. My body sure would love not having to try and cut it out and dump each fall.
