Lantana tolerates very light frost, but if temperatures drop down to 28 F or below, the plants will die back to the ground. Within the hardiness zones 8 through 11, lantana will come back the following spring from the roots. Wait until the first frost has killed off the growth before mulching.
Also, when should I cut back Lantana after freezing?
In late winter or early spring, you should prune lantanas back to about six inches to a foot from the ground, especially if there's a lot of old or dead growth. Overgrown plants can be pruned back to about a third of their height (and spread if necessary).
One may also ask, does lantana grow back every year? Lantana plants are moderately winter hardy. Some people have lantana that are perennial in nature and come back every year, while others replant every season. Lantana plants will die to the ground usually following a killing frost. At that point you can cut off the old foliage and mulch them for the winter.
Just so, can Lantana survive winter in Zone 7?
Winter Care for Lantana Plants. may remain evergreen and bloom year-round in frost-free or virtually frost-free climates such as U.S. Department of Agriculture plant hardiness zones 9 to 11. However, the plant will die back to the ground in USDA zone 7 and often in USDA zone 8 as well.
Why did my lantana die?
Fungal diseases Excess moisture and warm temperatures encourage spore formation. Botrytis blight, a common ornamental fungal disease, causes drooping, discoloration and can make it look like a lantana bush is dying. Prune out infected tissue and avoid overhead watering. Rust fungus also may be a problem.
