Hello - I've had a look about on past threads and found the Germination Temps one, which is really helpful and says that Cauliflowers need a minimum germ. temp. of 4 degrees. I sowed my caulis two weeks ago now and all the other brassicas I sowed at the same time (in fact all the seeds I sowed, except the squash seeds, again!) have germinated and are growing well (in small pots outside) but I have a complete no show from the caulis. I have kept them in the blow away to keep the temp more consistent but 'nada'. Does anyone have any secrets for germinating caulis?? I know they can be a bit of a pest to grow but last year I didn't have any problems (apart from getting cauliflowers in March when I thought I'd have them in December 
).
).
I started some seeds off in March in a propagator on my windowsill which are now all in the ground. I've also experimented, some seeds were sown into a trough in peat free multi-purpose in my blow away greenhouse and they all germinated and are currently in individual pots.
