Geraniums are a favorite among gardeners for their bright, cheerful blooms and low-maintenance care. Whether you grow them in your garden or in pots, their vibrant colors and hardy nature make them a must-have. However, when winter arrives, many gardeners let their geraniums fade with the cold frost, assuming they are a seasonal plant that cannot be saved. The good news is that with a few simple techniques, you can overwinter your geraniums and have them flourish again when the warm weather returns.
In this article, we’ll explore four easy and effective methods for overwintering geraniums, so you can enjoy these lovely plants year after year. By employing one or more of these strategies, you can save your geraniums from the frost and ensure that they’ll bloom beautifully next spring.
Why Overwinter Geraniums?
Before we dive into the steps, let’s first look at why overwintering geraniums is beneficial. In many regions, geraniums are grown as annuals because they cannot survive freezing temperatures. However, with the right care, geraniums can be kept alive through the winter months, saving you the time and money of purchasing new plants every spring.
Overwintering geraniums not only helps you save money, but it also allows you to preserve your favorite varieties. Some geranium cultivars can be difficult to find at garden centers, and overwintering lets you keep plants with special sentimental value. Plus, geraniums are known for being relatively easy to propagate, meaning that overwintering can also give you an opportunity to grow even more plants for next year.
Method 1: Bring Your Geraniums Indoors
One of the simplest and most effective ways to overwinter geraniums is to bring them indoors before the first frost. Geraniums can thrive indoors as long as they get the right amount of light and care.
Step-by-Step Instructions:
- Timing: Begin bringing your geraniums inside before the first frost hits. If you wait too long, the cold can damage the plants, making it harder for them to bounce back once indoors.
- Inspect and Prune: Before bringing your geraniums inside, inspect them for pests such as aphids or spider mites. If you find any, treat the plants with an organic pesticide or rinse them with water to remove pests. It’s also a good idea to prune back any dead or damaged leaves and stems to help the plant focus its energy on new growth.
- Choose the Right Location: Place your geraniums in a sunny spot indoors. A south or west-facing windowsill is ideal, as geraniums need at least 4-6 hours of direct sunlight per day to thrive. If you don’t have a sunny spot, you may need to supplement with artificial grow lights.
- Watering: During the winter, geraniums do not require as much water as they do in the growing season. Water sparingly and only when the top inch of soil is dry. Be careful not to let the soil become waterlogged, as this can lead to root rot.
- Temperature: Geraniums prefer temperatures between 60°F (15°C) and 70°F (21°C). Avoid placing your plants near heat vents or in areas that experience drastic temperature fluctuations, as this can stress the plants.
- Fertilizing: Geraniums generally do not need fertilizing during the winter months. Wait until the growing season begins in spring to start fertilizing again.
Method 2: Take Cuttings to Propagate Geraniums
If you have limited space or don’t want to bring the whole plant indoors, propagating geraniums by taking cuttings is an excellent option. This method is straightforward and allows you to grow new plants without taking up too much room.
Step-by-Step Instructions:
- Choose Healthy Stems: Select healthy, non-flowering stems that are about 4-6 inches long. Use a sharp, clean pair of scissors or pruning shears to make the cut just below a node (where the leaves meet the stem).
- Remove Lower Leaves: Trim off the lower leaves from the stem, leaving only a few leaves at the top. This will help the cutting focus its energy on root development rather than maintaining leaves.
- Prepare the Cutting: Place the cutting in a small glass of water or in a container with a moist potting mix. If you choose to use water, make sure to change it regularly to keep it clean. If you’re using soil, ensure the container has good drainage.
- Rooting in Water: If you choose to root the cutting in water, place the container in a bright spot but away from direct sunlight. After a few weeks, you should see roots forming. Once the roots are about an inch long, you can transplant the cutting into a small pot with well-draining soil.
- Rooting in Soil: If rooting in soil, keep the cutting moist but not wet. Covering the pot with a plastic bag or clear plastic dome will help maintain humidity and encourage rooting. Check the cutting for roots after a few weeks by gently tugging on the stem.
- Planting the New Geraniums: Once your cuttings have developed strong roots, plant them in a small pot with a good-quality potting mix. Keep them in a sunny spot and continue caring for them as you would a mature geranium. In spring, you can transplant them to your garden or larger containers.
Method 3: Overwintering Geraniums in Containers
If you prefer to keep your geraniums in their original pots, you can overwinter them by carefully moving the entire plant to a cool but frost-free location, such as a basement or garage. This method allows you to store the plants without having to prune or cut them back.
Step-by-Step Instructions:
- Preparation: Trim back any dead or diseased growth from the geranium. This will reduce the plant’s stress while it’s dormant.
- Find a Suitable Location: Choose a cool, dark location that remains above freezing (ideally around 40°F to 50°F or 4°C to 10°C). A basement, cellar, or unheated garage is ideal.
- Watering: Water the plants lightly after moving them to the cool location. Once the soil has dried out, stop watering altogether. Overwatering during dormancy can cause root rot, so it’s important to keep the soil relatively dry.
- Monitor the Plants: Check on your geraniums periodically throughout the winter. If the leaves begin to droop or show signs of dehydration, give the plant a light watering.
- Reintroduce to Light: Once spring arrives, bring your geraniums back into a sunny spot and resume normal watering and care. With a bit of attention, your plants should soon start growing again.
Method 4: Hang Geraniums Upside Down
For those with limited space, hanging geraniums upside down in a cool, dry place can be an unconventional yet effective way to overwinter your plants. This technique is great for people who want to save space and avoid the hassle of pruning or replanting.
Step-by-Step Instructions:
- Prune the Plant: Trim the plant back to about 6 inches in height, removing any large leaves or stems. This will help the plant focus on staying dormant rather than producing new growth.
- Hang the Plant: Hang the geranium upside down in a cool, dry location, such as a basement or shed. The roots will go dormant, and the plant will survive without direct sunlight or excessive watering.
- Check Periodically: Every couple of weeks, check the plant for signs of dehydration or pest infestation. Water lightly if needed, but don’t soak the roots.
- Replant in Spring: In the spring, when temperatures warm up, replant the geranium in a new pot or your garden. You should see new growth sprouting shortly.
Conclusion
Overwintering geraniums is a fantastic way to ensure that your favorite plants survive the winter and come back strong next year. Whether you decide to bring them indoors, take cuttings, store them in containers, or hang them upside down, there are several options to suit different needs and spaces. By using these methods, you can enjoy your geraniums year after year, saving time and money while contributing to a more sustainable gardening practice. So don’t let winter catch you off guard—take action today and ensure your geraniums bloom beautifully again next spring.
