You could do but not too warm. I personally would wait until mid march and start them off with out extra heat. Just remember they dislike the frost.

Sbg,..I was going to ask that as well..as I bought some at the weekend..so thank you for the reply to Grans garden :o)

Now is miles too early - the plants will be too big for your propagator & wherever else you might want to put them, before the weather is anywhere near warm enough to plant them out. I agree with SBG that mid March is plenty early enough to start them off.

Thank you SBG and Beattie. I will wait until mid march.
