NORWALK - This week's frosty nights could spell trouble for some gardeners.

Local florists say flowers like tulips, daffodils and pansies will do just fine in this week's weather. However, it's a different story for summer or tropical plants like geraniums, petunias or most vegetables.

Tony Vitti, of Nielsen's Florist & Garden Shop, says if those summer plants are in containers, they should be brought inside. If they have been planted in the ground, they should be heavily covered in burlap or some kind of cloth to protect from the frost.

Even then, florists say the temperatures may be too severe save those plants if they remain outdoors.

Experts say to wait until late May or Memorial Day weekend to plant those summer flowers.
