I have a greenhouse, and a number of heated propogators that I keep in a heated summerhouse (to mollycoddle two guinea pigs over the winter!). How soon can I sow tomatos, cucumber and courgette seeds?
I'm not sure about the cucumbers and courgettes but the toms you can sow form about late February onwards... the worlds your oyster!
I sow my tomatoes from week 8 till 10
courgettes and cucumbers from week 17.....
Too cold and not enough sun yet >:(
I start March 1st ( St. Davids day) personal pref.
have a look at this site done by Gavin I think I have saved it for info.
