Spanish lavender, also known as Lavandula stoechas, is not as winter-hardy as English lavender. It is typically only hardy to Zone 8, which means it may not survive the colder temperatures in areas with harsh winters. If you live in a region with a milder climate, where temperatures rarely drop below freezing, Spanish lavender may be able to survive outdoors.
However, if you live in an area with colder winters, it is recommended to bring Spanish lavender indoors to protect it from the freezing temperatures. This can be done by either transplanting it into a pot and bringing it indoors or by covering it with a protective layer of mulch or straw.
Bringing Spanish lavender indoors can be a simple process. First, choose a well-draining pot that is large enough to accommodate the plant’s root system. Fill the pot with a high-quality potting mix that is suitable for lavender. Carefully remove the lavender from the ground, taking care not to damage the roots, and gently place it into the pot.
Place the potted lavender in a sunny location, such as a south-facing window, where it can receive at least six hours of direct sunlight each day. Water the plant regularly, allowing the soil to dry out slightly between waterings. Be careful not to overwater, as lavender prefers dry conditions.
During the winter months, when the temperatures drop, it is important to protect the plant from drafts and extreme temperature fluctuations. Avoid placing the lavender near drafty windows or doors, as this can cause stress to the plant. If necessary, you can use a grow light to supplement the natural light and provide the lavender with the necessary light it needs to thrive indoors.
It is worth noting that Spanish lavender is more sensitive to overwatering and excessive moisture compared to English lavender. Therefore, it is important to be mindful of the watering needs and ensure the plant is not sitting in waterlogged soil.
If you are unable to bring Spanish lavender indoors for the winter, you can also try covering it with a layer of mulch or straw. This provides some insulation and protection against the cold temperatures. However, this method may not be as effective in regions with extremely cold winters.
While Spanish lavender is not as winter-hardy as English lavender, it can still survive in milder climates or with proper protection indoors or outdoors. It is important to assess your specific climate and take appropriate measures to ensure the survival of your Spanish lavender during the winter months.
