Environment Canada has issued a frost advisory for the southern and eastern parts of the province.

Widespread frost is expected Friday night and early Saturday morning.

The exception is those areas very close to the Great Lakes where temperatures will remain a couple of degrees above freezing.

Gardeners should cover up their plants or bring them inside.

"We've literally got thousands and thousands we have to bring in. Some we put under the tables and cover with ground cover and hopefully that saves them," says Janet Szusz of Greyhaven Gardens near Londesborough.

The possibility of  frost has gardeners everywhere reaching for their burlap and bags to cover their precious plants this evening.
Farmers would do the same if they didn't already have their corn and beans in the ground.

"At least its been kind of cold the last couple days and nights so the plants are little bit acclimatized to the conditions so that might be enough to give them just enough edge to make it through the cold nights," says Peter Heinrich, a Blyth area farmer.

Heinrich is the first to admit farmers are their own worst enemy on this occasion.

Most corn and soybeans are in the ground already knowing full well a frost was possible in late may.

"Conditions were just too perfect earlier this month," her says.

Today's corn and soybean seeds are hardier than decades past.

But they still can't resist the frost.

Heinrich is more worried about soybeans than he is corn.

The amount of damage depends on how long it stays below freezing.

"The general rule is 2.5 and -2.5 at the stage they're at right now. But in some low spots it might hit -3 for a few hours and we might lose some there. But I dont' think we're going to have a total wipe out tonight," says Heinrich.

More precious plants may not be so lucky if left uncovered.

Gardeners are praying that this is the last frost this spring.

"We're hoping. Please, we need nice weather. We've got lots of plants here looking for their forever home. So we'd like to get them out there and people's homes looking beautiful for summer," says Szusz.
