I'll look into that, thanks. I have tried horticultural sharp sand in the past, which didn't work, also tried perlite last year, which did work for most of the year, but I think the little buggers found their way into the bottom of the pots. They are a reall problem for me and usually result in me having to bin all my plants instead of over wintering as they are infested by the end of summer
.
I'm thinking the mesh will totally stop them getting into the bottom holes, but still let water drain out. Same with the top. Then put a layer of grit or sand on top of the mesh to hold it down.
