I've got a ceramic bowl and I would like to plant up with succulents for indoors. It doesn't have any drainage though. Should I put a layer of stones at the bottom and then sandy soil mix on top? Alternatively I thought I could almost fill the bowl with gravel and bury small individual draining plant pots in it. I could then lift out the individual pots to water & drain them before sitting them back in the gravel.
Please could you advise?
I've been looking at plants and thought maybe miniature aeonium, sempervivium and echeveria although suggestions would be very welcome.
