It's actually not a pot but a wooden container holding 3 plants, 3ft x
1.5ft approx with a good 15" soil. So there's no dish needed, there are
holes enough. I have other plants in far smaller clay pots and they're
fine. Infact at the moment they are all fine except this one plant. In
previous years I've had the wilting problem with certain plants but
later when the plants have fruit, and it was blossom end rot that was
the problem. Could it be the same virus, but at such an early stage?
