I know that Home Depot "recycles" the black pots.. You can probable ask them. A few years ago when I only had about 30-40 roses & didn't know about burying them up to their eyeballs to protect them from the winter, what I did is find a landscaper who was putting in a ton of 3 gal shrubs. I asked them if I could have their buckets & they were estatic to have me take them! I cut the bottoms off of each one, put the now hard-plastic cone around the rose, and filled each one with mulch. Worked like a charm. Not practical for me to do that now.. Got too many roses to do that to!
