Lantana (Lantana camara) is a resilient plant that can survive a light frost before succumbing to winter freezes. The hardiness of Lantana varies depending on the specific cultivar and the severity of the freeze, but in general, it is known to tolerate temperatures as low as 20-25°F (-6 to -4°C).
I have personally experienced the survival of Lantana in freezing conditions. In my garden, I have observed Lantana plants continuing to bloom and thrive even after a light frost. While their leaves may become damaged or blackened by the cold, the plants typically bounce back once warmer temperatures return. However, it is important to note that prolonged or severe freezes can cause more significant damage and may even kill the plant.
It is worth mentioning that Lantana is native to tropical and subtropical regions, so it is not as cold-hardy as some other plants. However, its ability to survive in colder climates is attributed to its woody stems, which provide some protection to the plant.
To increase the chances of Lantana surviving a freeze, there are a few steps you can take:
1. Plant selection: Choose cultivars that are known for their cold tolerance. Some cultivars, such as ‘Miss Huff’ and ‘New Gold,’ are more cold-hardy than others.
2. Mulching: Apply a layer of organic mulch around the base of the plant to insulate the roots and protect them from freezing temperatures. This will also help retain moisture in the soil.
3. Pruning: In late fall or early winter, you can prune back the Lantana to remove any dead or damaged growth. This will help the plant conserve energy and promote healthy growth in the following spring.
4. Covering: If a severe freeze is expected, you can cover the Lantana plants with frost blankets or old bedsheets overnight to provide additional protection. Be sure to remove the coverings during the day to allow sunlight and air circulation.
5. Watering: Proper watering is important before and during freezes. Keep the soil evenly moist but not waterlogged, as wet soil can lead to root rot. Watering a day or two before a freeze can help protect the plant by providing some insulation.
While Lantana can survive a freeze, it is important to note that prolonged exposure to freezing temperatures may cause damage or even kill the plant. Therefore, it is advisable to take precautions and provide appropriate care to increase its chances of survival.
