Courgettes - when dare I ............... ?
I usually sow my courgettes in fibre pots indoors, then grow them on in the mini-greenhouse, eventually planting out into a raised bed in early June.
I have a plastic cover which I could erect over the raised bed, like this one http://www.greenfingers.com/superstore/product.asp?dept_id=200462&pf_id=LS7730D&co=fr&gclid=CIm8la3alL0CFenjwgodnikAeg
and I'm wondering whether there would be any advantage to fitting the cover, warming the bed up and direct sowing the courgettes into the raised bed, keeping the cover over until all threat of frost and cold weather has passed?
Do you think I would get an earlier crop, and if so, how early would you risk sowing directly into the raised bed?
