Gaillardia, commonly known as blanket flower, is a vibrant perennial that adds bright colors to gardens. When grown in containers, it requires special care to survive the cold winter months. Overwintering Gaillardia successfully in containers ensures you can enjoy its beauty year after year.
Preparing Gaillardia for Winter
Proper preparation is essential for overwintering Gaillardia in containers. Start by assessing the plant’s health and size. Remove any dead or diseased foliage to prevent issues during dormancy. Gradually reduce watering as the plant enters dormancy, typically in late fall.
Choosing the Right Container
Select a container that provides good drainage and insulation. Terracotta and ceramic pots are popular choices, but ensure they are not too large, which can retain excess moisture. Consider wrapping the container with insulating materials or placing it in a sheltered location.
Insulating Your Containers
- Wrap containers with bubble wrap or straw.
- Place containers on risers to prevent direct contact with cold ground.
- Group multiple containers together for added warmth.
Location and Shelter
Move the containers to a sheltered spot such as a garage, shed, or porch that is protected from harsh winds and extreme cold. Ensure the location receives some sunlight during winter days to prevent excessive dormancy stress.
Temperature Considerations
Gaillardia is hardy to USDA zones 4-9. If you are in a colder zone, extra insulation or indoor overwintering may be necessary. Maintain temperatures above freezing to prevent root damage.
Watering and Maintenance During Winter
Reduce watering significantly during dormancy. Only water when the soil is completely dry to prevent root rot. Avoid fertilizing during winter, as the plant’s growth slows down. Regularly check for pests and signs of disease.
Resuming Growth in Spring
As temperatures rise in spring, gradually move the containers to a sunnier location and resume regular watering and feeding. Remove any dead foliage and encourage healthy new growth. With proper care, your Gaillardia will bloom again in the growing season.
