You can definitely leave your geraniums in pots over winter. In fact, it is often the easiest and most convenient way to overwinter these beautiful plants. By keeping them in pots, you have the flexibility to move them into a suitable winter location without disturbing their roots.
One option is to move your potted geraniums into a greenhouse or conservatory. These spaces typically provide the ideal conditions for overwintering plants, as they are light, airy, and frost-free. Geraniums thrive in bright, indirect light, so placing them near a sunny window or under grow lights can help them continue to grow during the winter months.
If you don’t have access to a greenhouse or conservatory, you can still successfully overwinter your geraniums indoors. Find a well-lit spot in your home, such as a sunny window or a room with ample natural light. Make sure the temperature remains above freezing, as geraniums are sensitive to frost.
To prepare your geraniums for overwintering, there are a few steps you can take. First, trim back any leggy or overgrown growth to encourage a more compact shape. Next, check for any signs of pests or diseases and treat accordingly. It’s also a good idea to inspect the roots and repot your geraniums if they appear root-bound or if the potting soil is depleted.
When moving your geraniums indoors, be mindful of the sudden change in environment. Gradually acclimate them to the lower light levels and indoor conditions by initially placing them in a shaded area for a few days before bringing them inside. This will help minimize stress and ensure a smoother transition.
In terms of care during the winter months, geraniums tend to require less water and fertilizer compared to their active growing season. Allow the soil to dry out slightly between waterings, but be careful not to let it become bone dry. Overwatering can lead to root rot, so it’s important to strike a balance.
If you have a large number of geraniums and prefer not to keep them in pots, another option is to store them in bareroot form. To do this, carefully dig up the geraniums, shaking off excess soil from the roots. Trim back the foliage to a few inches above the crown and remove any damaged or diseased parts.
Gently wrap each bareroot geranium in newspaper or place them in paper bags to protect them during storage. Find a cool, dry place to store them, such as a basement or garage, where the temperature remains consistent and above freezing. Check on them periodically to ensure they are not drying out or showing signs of rot.
When spring arrives, you can replant your overwintered geraniums by potting them up and gradually reintroducing them to outdoor conditions. With proper care and attention, your geraniums should bounce back and reward you with beautiful blooms throughout the summer.
Whether you choose to keep your geraniums in pots or store them in bareroot form, both methods can be successful for overwintering these plants. Consider your available space and resources, as well as the number of geraniums you have, to determine the best approach for your situation. Happy gardening!
