You plant them in February? How do you keep them warm and with enough space
until June when you can plant them out?

I think I plant my first batch of courgettes and squashes in Feb, yes.
I could be mis-remembering. They go in pots on the window sill, then
out into the greenhouse. Iirc, they get planted out in about April.

Of course, this could be why I tend to lose a lot of them. :-/
(but normally to snails, and from planting them out when they are too
small, rather than from frost!)
