When can i plant my onion seeds out

[New shoot]

Seedlings can be knocked back by frosts, so I usually wait until late April or early May, although they will have been in the cold frame for several weeks before that.

You are aiming for a fairly consistent 10-15 degrees C for them to keep growing steadily.
