Hi all

A few basic questions from a relative newbie if I may:

Should "Tender Green" french beans need supporting?
Should the above produce curly or straight(ish) beans (mine are distinctly
curly).
How do you tell when onions are "ready". I have a dozen or so that have
filled out to a decent size, but should the tops die off/flower/seed or
whatever before harvesting?
A few small courgettes have formed behind flowers, but then disappeared.
Are they being snaffled by some local sneak thief or is there something that
needs to be done to make these "set"?
Why do tomatoes do so much better in grow bags? I have planted some in open
ground, but with at least a 50% local addition of seed compost. So I was
expecting a similar result to the grow bags - but no, much slower and less
convincing foliar growth.

Any comments/suggestions appreciated.

Phil
