Another poster on here talked about his Italian neighbour and the only 2 words of English he ever spoke before mid May:"too early, too early".It's the same with sweetcorn, you have to restrain yourself. Still lots of other things you can be starting inside in the meantime.
Where did you get the seeds that the packet says you can sow now?Most my squash seeds say sow April-May, my packet of Harrier says May-June.If it is too cold when they go out, they will just sulk, and continue to sulk even when it has warmed up, so it is better to plant to late rather than too early, and now I have told somebody else that maybe I will remember it myself.
