Hi All,

Anyone grown Borettana Onions from seeds before? I've never grown onions before and thought I try it this year. I sowed a couple indoors using a heat mat in the last week of February and then a couple more in early March when the first batch didn't germinate. Now none of them have germinated. There's no sign of anything growing in the containers. Everything else that I've sowed indoors has germinated except these onions. Do I have to do something extra with these onion seeds? Should I direct seed them outdoors when it gets warmer?
