Should I water the pots (which are clay of course) or just keep the sand moist at all times?

Hello Keith. There is no simple answer to your question. It depends on the time of year, the weather and the plant. In winter I only water the plunge and then sparingly, just to keep it damp. In hot summer weather I spray everything liberally once the sun is off the plants, to help cool things down. Most often I water the plunge and then around the rim of the pots to a lesser extent. Nevertheless, I know there is a danger that the centre of large plants can get too dry and I do occasionally water into the cushion or mat as well, especially as the plants come into growth and set buds. This would probably kill most dionysias however!Often, when large plants in crock pots are repotted, the roots are found to be restricted to the edge, because this is where they get most of the water, and clearly, this is not ideal. As with most other aspects of gardening, it is all a matter of common sense and intelligent guesswork, otherwise known as green fingers!

Thanks John. This is more or less what I had been doing, but it's good to know I am on the right lines.
