Many thanks for all of your help with this one. It has been very much appreciated.
I tried vegplugs, but, for some reason, kept getting the message that they couldn't supply the seeds to my country... which is a bit strange as I live in UK ! It's probably a computer glitch, so I e-mailed them to let them know.
Being a 'sow-my-own' man, I have not checked out sites selling plants.
Wallis Seeds came up trumps ! I was not aware of their site before and was impressed with what they have on offer at very reasonable prices. So I bought some "Pentland Brig" seed along with some "Dwarf Green" Kale and some "Brussels Witloof" Chicory as I am planning to have many more crops growing through the Winter months.
