@LizDTM Lis, it works well but the paper filters do break down after awhile, even when doubled. I tried window screening cut to the size of pots but then when it came time to repot, I'd find the plants roots entangled in the screen and I'd have to cut them away, so I went back to using the paper filters.
Although I've used old knee highs cut into strips for tying vines and plants to stakes, I never thought of using panty hose to keep soil in the pots as member revclaus/Judith mentioned in her comment on this page:
The thread "More than one!" in
A Quick Tip on Container Planting I wonder though if roots would become entangled in the nylon as it did with the mesh screen?
Member samigal/Peggy also had a good idea that she posted on that page and I think the black fabric that she was referring to might be that landscape weed-guard fabric used in flower beds to help keep weeds down. We've used it for it's intended purpose here in Florida many times and I might have to cut some of it to size and try it in the bottom of pots since it's supposed to drain well and I'm sure it would last much longer than paper filters. But then again, I wonder if plant roots would grow into the fabric and make it difficult when removing the plant for repotting?
LOL, maybe I should repot my plants more often instead of waiting until the roots become entangled in whatever is in the bottom of the pot.
