Protecting plants from freezing temps

NEW ORLEANS, La. (WVUE) - Many will brave the cold temperatures to drag in potted plants and cover flower beds. One expert says you may not have to work as hard as you think.

Plants are included in the four P’s when it comes to freeze protection. Garden manager at The Plant Gallery in Metairie Wayne Soniat says a lot of our common plants this time of year can handle the cold just fine.

As soon as there is a sign that temperatures will fall below 32 degrees plant lovers are thinking about how to make sure their beloved specimens survive.

“You really want to focus on your tropical plants. You know Louisiana has a ton of tropical plants. Hibiscus, palms, and different things like that. You want to make sure that those are covered both on the top and if it’s in a container, you want to cover that container also,” said Soniat.

For large palms make sure the roots are well protected.

“Really you cover as much as you can. We do have some enormous palm trees out on the landscape, but you cover as much as you can. But most importantly, try and cover the root zone by applying d ense mulching right at the base.”

Another common item you’ll find covered up are azaleas, but Soniat says that’s one you can probably skip.

“Everybody does have azaleas. Those are definitely hardy. Those will last through the frost, and you don’t really have to worry about those.”

If it’s a Fall plant like snapdragons, crocus or mums, the flowers will get beat up, but the plants will be fine." Soniat said. “These are plants that people put out to add some color to their beds and typically just put out.”

For more delicate plants, old sheets will work or most nursery and hardware stores carry breathable covers that hold in the warmth.
