Yes Deer
Your right that they will be fine if you bring em in at night, but he was talking about planting seeds directly in the soil outside. They will still probably survive, I just stated that it's not the ideal time. I am at least 100 miles south of there, and the last threat of frost in my town is 4/20, although a frost that late is rare. Basically what we do is look at the 10 day forcast on about 4/15. If no freezing temps are predicted, that's when we plant annuals.

good luck to all.
