I'm pants at brassicas

they either get got by cabbage white caterpillars, or I'm lacking space when they need to be transplanted out. So long as I manage a few sprout plants each year, I don't get too wound up about it.
Received the Sarah Raven book for Xmas, was a bit floaty laura ashley perfect for me, but one tip that has stayed with me is that brassicas put down a long tap root first, so am planning on sowing them in deeper pots this year, possibly kitchen roll tubes, but will pop 8+ into a big flower pot, rather than the 2 -3 inch tray I normally use.
I don't have a seed bed area so can't start them off there.
Time to get your tomatoes in soon for unheated greenhouse crops - sow around Valentines Day on the window sill ready for putting in the unheated greenhouse - which I tend to do around the first May bank holiday.
