Geraniums, while beautiful and vibrant plants, are not typically able to withstand the harsh conditions of winter, especially when exposed to freezing temperatures. These plants are not frost-tolerant, which means that if exposed to frost, they can suffer damage or even perish.
However, if you happen to live in a climate zone that experiences mild winters, such as USDA zones 10 and 11, you may have a better chance of successfully overwintering your geraniums outdoors. In these zones, where the winters are relatively gentle, geraniums can often survive being left outside year-round.
For those gardeners who live in areas with colder winters, there are several options available to help protect your geraniums from the harsh conditions and ensure their survival until the warmer months return.
One effective method is to bring your geraniums indoors for the winter. By transplanting them into pots and placing them in a sunny window or under grow lights, you can create a warm and sheltered environment that will help your geraniums thrive throughout the colder months.
If bringing your geraniums indoors is not feasible, another option is to dig them up from the ground and transfer them to containers. Once in pots, you can store them in a sheltered location, such as a garage or shed, where they will be protected from the cold temperatures and harsh winter conditions.
Alternatively, you can opt for a method known as “geranium hibernation.” This involves cutting back the foliage of the geraniums, digging them up from the ground, and storing them in a cool, dark, and dry location. Periodically check on them to ensure they are not drying out or rotting.
Another popular technique for overwintering geraniums is to take cuttings from the plants before the onset of winter. By rooting these cuttings in water or a rooting medium, you can create new plants that can be kept indoors throughout the winter and then transplanted back outside in the spring.
If you prefer to leave your geraniums outdoors during the winter months, it is essential to take precautions to protect them from the cold. One option is to cover the plants with a layer of mulch to insulate them from freezing temperatures and provide some protection from frost.
Additionally, you can use cloches or row covers to shield your geraniums from the elements and create a microclimate that is more conducive to their survival. Make sure to secure the covers properly to prevent them from blowing away in windy conditions.
Ultimately, whether or not your geraniums can survive outside in the winter will depend on various factors, such as your climate zone, the severity of the winter weather, and the specific care and protection measures you provide for the plants. With proper planning and attention, you can increase the chances of your geraniums making it through the winter and thriving once again in the spring.
So, while geraniums may not be naturally equipped to endure the harsh conditions of winter, with a little effort and creativity, you can help these beautiful plants survive the cold months and continue to brighten your garden year after year.
