I had two plants in the greenhouse and two outside. The green-house plants
produced approx six fruits each. They took ages to grow to a decent size and
had uneven skins with the odd pock-mark. A few still haven't reached full
size, but of those that did the taste was delicious.
The outside plants produced one fruit apiece and these are currently about
half-sized. Given the fabulous summer we've had I don't think I'll bother
growing 'em outside again.
No special efforts needed other than misting when in flower and feeding when
in fruit.
