Is It Ok To leave Seedlings Outside?

Q: I started a lot of seeds for my garden. I have them planted in small trays. I’m running low on space inside so is it ok to leave them outside for the night?

A: I would not leave seedlings outside until nighttime temperatures are reliably above 55°. It will be mid- to late April before that happens. Keep looking for creative places where you can keep them indoors, so the soil will stay warm continuously.
