A frost advisory has been issued for part of the province, including the Halifax area.
Environment Canada said light winds along with fairly clear skies will create favourable conditions for frost formation Thursday night into Friday.
They recommend taking preventative measures to protect frost-sensitive plants and trees.
In an interview last week, NEWS 95.7's Weekend Gardener, Niki Jabbour, said you can simply cover your tender vegetables and herbs, like tomatoes and basil, with an old bed sheet.
"Honestly any type of fabric will help protect your vegetables," she said. "Even a cardboard box or a bucket on top of it is going to be enough to protect from frost."
Environment Canada is calling for an overnight low of 5, but said it could drop down to 2 in low lying areas.
