DENVER -- An impending snowstorm is causing concerns for gardeners and homeowners whose plants and flowers are already blooming.

Vviewer Jason Arnold asked if he should take protective action for his active flower bed.

"My big concern is I don't want my flowers die from frost. I don't know if I should cover them. I'm not sure what's a good temperature to cover them," Arnold said.

Springtime means plants are awakening from their winter slumber. The flowers that are bursting their buds are perennials, which bloom every year, including, pretty pansies, vibrant violas and dazzling daffodils. And there's not much to do for them.

"Let the snow fall on them. It will help insulate them, keep the moisture in," said John Smith with Paulino Gardens in Denver. "A moist plant will have less problems with freezing. It's the dry cold that kills most things."

Snow insulates plants much like igloos protect people, said Smith, adding that problems arise if there's no snow and temperatures drop below 20 degrees.

"Those are the ones that can really harm plants, turn leaves black," he said.

Those who want to give plants some extra warmth can use an insulation cover to add 5 to 10 degrees.

"Unless we get a foot or more of snow, these are the sorts of things you can use," Smith said.

But with a foot or more, you'll want to knock snow off a blooming tree or risk broken branches. Watering plants will give it moisture that helps protect it.

“I feel a lot better about it. I think all my plants will make it through," Allen said. “Then after (Wednesday's storm), everything should be blooming and be pretty for the rest of the summer.”
