First let me say hello and welcome no I have not seen these but be interesting to find out how they hold out.

I tried hessian on my a patio for kitchen herbs but they got so wet and heavy with the rain we had that the plants infact rotted no drainage

Hi Scotkat Thanks for your reply Maybe they would drain better when they are hanging do you think?

A neighbour tried these and whilst they looked good to begin with the rapidly started to look tatty.
