I was having a clear-up around the compost heap today and came across a
marrow plant that I had discarded. It missed the compost bin and fell in
the
gap by the hedge. Despite not being hand-fertilised it had produced the
biggest b******* marrow of the season. AAAAAAGGGGHHHHH!

Next year? Definitely NO MARROWS!

Outdoor marrows/courgettes don't need hand pollinating in my experience.
