EASTON - Frost could mean trouble for crops across Connecticut.

A frost advisory is in effect overnight, mostly north of the Merritt Parkway.

Irv Silverman, of Silverman's Farm in Easton, says last year's frost killed about 75 percent of his crops. He also says frost can kill plants that people have recently planted outdoors.

Silverman says it's rare to see frost after Mother's Day. He warns that people should not put plastic on top of plants to shield them, but says wind can be helpful in protecting plants from frost.

Silverman's Farm will have giant fans blowing across the orchard to keep the air moving and the frost from settling.
