I'm an allotment/vegetable growing newbie .... have been reading up on everything and most things I've planted/sown are doing something at least. But my courgettes (which I'm most looking forward to growing as they're easy and prolific) haven't shown any signs of sprouting. I sowed them (on their sides as per Monty's instructions
) about four weeks ago and kept them in a greenhouse. Is there any hope or do I need to buy more seeds and start again? Any advice much appreciated
