Lantana Overwintering

Lantana is a tropical perennial plant that is known for its brightly colored flowers and its ability to attract butterflies and hummingbirds. They are commonly used in garden beds, borders, and as container plants. Lantana plants are hardy in USDA zones 8-11, meaning they can survive year-round in these regions. However, in areas with colder climates, Lantana plants need to be protected or brought indoors during the winter to survive. This process is known as overwintering.

Understanding Lantana Overwintering

The success of overwintering Lantana plants depends on several factors, such as the variety of Lantana, the climate of the area, and the care provided to the plant. Some varieties of Lantana are more cold-tolerant than others, so it is important to research the specific type of Lantana that you have.

Additionally, the climate of the area plays a role in the success of overwintering. For example, in areas with mild winters, Lantana plants may be able to survive outside with minimal protection. However, in areas with harsh winters, Lantana plants will likely need to be brought indoors or heavily protected in order to survive.

Proper care is also an important factor in the success of overwintering Lantana. This includes preparing the plant for winter by trimming and pruning, providing the right environment for the plant, and monitoring the plant throughout the winter to make adjustments as needed.

Overall, overwintering Lantana plants takes some effort and attention, but with the right knowledge and care, it is possible to protect Lantana and keep them alive through the winter months, to enjoy them in the next growing season.

Preparing Lantana for Overwintering

Preparing Lantana for overwintering is an important step in ensuring the survival of the plant through the winter months. Here are some steps to take before the first frost to prepare Lantana for overwintering:

  1. Trim and prune: Before the first frost, trim back the Lantana plant to about 6 inches in height. This will promote healthy growth in the spring and also make the plant more compact and easier to bring indoors or cover for protection.
  2. Stop fertilizing: Stop fertilizing the Lantana plant about 6-8 weeks before the first frost. This will help the plant to harden off and prepare for the winter.
  3. Clean up debris: Clear out any dead leaves or debris around the base of the plant. This will reduce the chances of pests and diseases overwintering in the same area.
  4. Move container plants: If you have Lantana in a container, move it to a sheltered location that is protected from frost and wind.
  5. Watering: Make sure to water the Lantana plant well before the first frost, as this will help to protect the roots from freezing.

By following these steps, you can help ensure that your Lantana plant is well-prepared for overwintering and is more likely to survive the winter months.

Indoor Overwintering Techniques

Indoor overwintering is an effective way to protect Lantana plants from the cold temperatures and frost of winter. Here are some options for keeping Lantana indoors during the winter:

  1. Greenhouses: If you have a greenhouse, this is an ideal location to overwinter Lantana plants. The greenhouse will provide protection from the cold and also allow for proper light and humidity levels.
  2. Windowsills: Placing Lantana plants on a windowsill that receives bright, indirect sunlight can also be an effective way to overwinter the plant. Make sure to keep the plant away from drafts and cold windows.
  3. Basement or garage: If you don’t have a greenhouse or a suitable windowsill, you can also overwinter Lantana in an unheated basement or garage. Keep the plant in a sheltered location, away from drafts, and protect it from frost.
  4. Artificial light: If the plant is not getting enough light, you may need to supplement with artificial light, like grow lights.

It’s important to monitor the temperature, humidity, and light levels when overwintering Lantana indoors to ensure the plant thrives. Lantana prefers temperatures between 60-70°F, humidity levels between 40-50% and bright but indirect light.

It’s also important to be aware of pests and diseases which can be carried over from outdoors, so it’s a good idea to inspect the plants and to treat them if necessary.

Overall, by providing the right environment and care, Lantana can be successfully overwintered indoors, allowing you to enjoy the plant again in the spring.

Outdoor Overwintering Techniques

Outdoor overwintering is another option for protecting Lantana plants from the cold temperatures and frost of winter. Here are some methods for protecting Lantana plants outside during the winter:

  1. Mulching: Mulching around the base of the Lantana plant with a layer of straw or leaves can provide insulation and help to protect the roots from freezing.
  2. Frost blankets: Covering Lantana plants with frost blankets or burlap can provide additional protection from frost and freezing temperatures.
  3. Cold frames: Another option is to place the Lantana plant in a cold frame, which is a simple structure that allows sunlight in but protects the plant from frost.
  4. Microclimates: Identify a microclimate in your garden, such as a sunny south-facing wall, or a spot near a building that might be sheltered from the wind, where the Lantana might have a better chance of survival.

It’s important to monitor the weather forecast and take action as soon as the first frost is expected. Also, it’s important to remove the protection when the temperature is expected to rise, to avoid the plant to overheat.

When deciding whether to move Lantana plants indoors or leave them outside for overwintering, it is important to consider the specific variety of Lantana, the climate of the area, and the level of protection that can be provided. Some varieties of Lantana are more cold-tolerant than others and may be able to survive outside with minimal protection, while others will need to be brought indoors or heavily protected to survive.

Overall, by providing the right level of protection and care, Lantana plants can be successfully overwintered outdoors and will be ready to thrive again in the spring.


In conclusion, Lantana plants are tropical perennials that need protection from frost and freezing temperatures to survive the winter. Overwintering Lantana plants involves a combination of preparation, proper care, and protection from the cold. Preparing Lantana for overwintering includes trimming and pruning the plant, stopping fertilization, cleaning up debris, and providing adequate water before the first frost.
