Was it Hugh, who came up with ". . . but the second mouse gets the cheese?"
I've found parsnips sown according to the packet and the books to be very patchy - poor germination, and I haven't tried leeks this early.
Sowing just a bit later, once the soil's a bit warmer? Gut feeling that later sowings romp away, and soon catch up with early sowings, which have had a couple of frost checks?
No science in there whatsoever - just bone idleness, and a liking for a warm fire!
Idle, but warm - Gavin
Ebagum - forgot the "Yorkshire bare-arse" test; if you can bare your bum and sit on the soil, it's warm enough to sow. Pity, though - you also get locked up!
