Good Morning All

I am trying to grow some sweetcorn and have put 6 corns in pots inside a
propagator about one month ago and they do not seem to be doing anything.
Has anyone ever tried to grow sweetcorn? How long does it take to germinate
usually? I have tried to look online but I can not seem to find anything on
sweetcorn germinatation.

Am debating just chucking the ones I have planted and trying some new seeds.

Thank you
Donna
