Geraniums are beautiful flowering plants that can add vibrant colors to any garden or home. However, when the temperatures start to drop in October, it’s time to think about overwintering these delicate plants.
According to gardening expert Clapp Pags, the best time to overwinter geraniums is in October when the plants are still in their prime and haven’t been affected by the cold weather yet. To do this, it’s important to cut back the geraniums and remove any dead or dying flowers. Then, they can be potted and placed in a frost-free greenhouse or conservatory to protect them from direct cold temperatures.
In terms of care, it’s important to keep the geraniums in a semi-dormant state during the winter months. This means they should be kept in a cool but not freezing environment, with temperatures between 45-50°F (7-10°C). Clapp Pags advises wrapping the pots in green bags to help retain moisture and prevent the plants from drying out.
If you don’t have access to a greenhouse or conservatory, Clapp Pags suggests storing the potted geraniums on a window ledge in the kitchen or a cool and dark room. It’s important to check on them regularly and water sparingly to prevent root rot. The plants may lose some leaves during this time, but they should bounce back in spring.
For those with a keen interest in growing geraniums, Clapp Pags recommends taking cuttings in July to create new plants. These cuttings can be wrapped in damp paper towels and stored in plastic bags in the refrigerator until spring. Once the weather warms up, they can be potted and brought back to life.
“Overwintering geraniums is an important process that can ensure the plants come back stronger and better than ever,” says Clapp Pags. “Taking the time to care for them during the colder months means you’ll have beautiful geraniums in your garden or home come spring.”
So, whether you have a large garden or a small border, overwintering geraniums is a great way to keep these delicate plants thriving during colder weather. By following expert advice and providing the right conditions, you can enjoy the beauty of geranium flowers in your home or garden all year round.
How to overwinter geraniums
Overwintering geraniums is a great way to ensure that your plants sleep through the cold winter months and then grow again in spring. If you want to create a beautiful garden with geraniums, it’s important to know how to properly overwinter them.
One method to overwinter geraniums is to store them in a cool, dry place, like an unheated basement or garage. In October, before the first frost, you can dig up the geraniums from your garden and place them in pots. Make sure to trim back any dead or overgrown foliage and gently shake off excess soil from the roots.
If you have a large enough pot, you can plant multiple geraniums together. This will help them maintain moisture and provide some insulation. Another option is to wrap each geranium individually in newspaper or burlap. This will help protect the plant from frost and cold temperatures.
If you have access to a greenhouse or a conservatory, you can place your potted geraniums there for the winter. The controlled temperature and light conditions in these spaces will provide the perfect environment for your plants to sleep and rejuvenate.
Watering and soil conditions
During the winter months, geraniums require less water than in the growing season. Watering should be reduced to once every two to three weeks. Make sure to keep the soil slightly moist, but be careful not to overwater as this can cause root rot.
It’s also a good idea to check the soil regularly and add water if it feels dry. If you notice any signs of wilting or drooping, it may be a sign that the plant needs watering. However, be cautious not to overwater, as geraniums are susceptible to root rot.
Temperature and light conditions
Geraniums are hardy plants and can withstand cold temperatures. However, they prefer temperatures between 45°F and 55°F (7°C and 13°C) during their semi-dormant state. If the temperatures outside drop below freezing, it’s important to protect your geraniums with insulation like burlap or newspaper.
Geraniums also need a good amount of sunlight to stay healthy. During the winter months, place your potted geraniums in a sunny location, like a south-facing window or a conservatory. This will provide them with enough light to keep them in good condition.
Expert advice from Emily
Emily, vice president of the Geranium and Pelargonium Society, shares her expert advice on overwintering geraniums:
“The key to successful overwintering is to replicate the natural conditions that geraniums would experience in their native state. This means placing them in a cool, unheated space and providing them with enough light and water to keep them alive but not actively growing.”
Emily adds that it’s a good idea to keep an eye on your geraniums throughout the winter months. If you notice any signs of disease or pest infestation, take action immediately. This will help ensure that your geraniums come back strong and healthy in the spring, ready to produce beautiful flowers.
How to overwinter geraniums in pots
Overwintering geraniums in pots can be a rewarding task that allows you to enjoy the beautiful flowers of these plants year after year. With the right care and protection, geraniums can be brought indoors and stored throughout the cold winter months, ready to bloom again in the spring.
1. Choose the right method
When it comes to overwintering geraniums in pots, there are several methods you can choose from. Whether you are an expert or a beginner, it is important to find a method that suits your skills and the conditions in which your geraniums are being grown.
- Unheated greenhouse: If you have access to an unheated greenhouse, this can be an ideal place to overwinter geraniums. The plants will receive protection from the cold, but still benefit from plenty of light.

When deciding where to overwinter your geraniums, it is important to choose a location that provides the right conditions. This includes a frost-free area with temperatures around 45-55°F (7-13°C) and plenty of light.
4. Provide care throughout the winter
Once your geraniums are safely tucked away for the winter, it is important to provide them with the care they need to stay healthy. This includes watering sparingly, as the plants will be dormant, and avoiding direct heat sources that can cause them to dry out.
5. Bring them back to life in the spring
As the weather starts to warm up in the spring, you can begin to reintroduce your geraniums to outdoor conditions. Start by gradually exposing them to more light and increasing their watering. Once the danger of frost has passed, you can safely move your geraniums back outside.
Following these steps will ensure that your geraniums survive the winter and come back with a burst of color in the spring. Whether you choose to overwinter them in an unheated greenhouse or bring them indoors, with the right care and protection, your geraniums can sleep peacefully and be ready to bloom again when the time is right.
Can I overwinter geraniums in an unheated greenhouse
Overwintering geraniums can be a great way to enjoy these beautiful flowers year after year. If you have potted geraniums that are annuals, it’s worth considering overwintering them to save money on buying new plants each season. One option for overwintering geraniums is to place them in an unheated greenhouse.
The Royal Horticultural Society advises that while geraniums are not truly perennial, they can be treated as such in terms of overwintering. An unheated greenhouse provides a frost-free environment, which is ideal for geraniums during the winter season. In October, before the temperatures drop too low, bring your potted geraniums into the greenhouse.
To prepare your geraniums for winter, expert advice recommends trimming them back to around half their size. This helps create a more compact and tidy shape and also reduces the risk of disease. You can also remove any flowers that may still be present.
Once your geraniums are trimmed and ready, place them in a greenhouse where they will be protected from frost. The cool temperatures in an unheated greenhouse will help the plants go into a semi-dormant state, allowing them to sleep through the winter months. Make sure to water them sparingly during this period, as overwatering can lead to rot.
If you don’t have access to a greenhouse, another option for overwintering geraniums is to wrap them in plastic bags and store them in a cool, dark place. This method can work well for geraniums that are kept indoors or in a conservatory during the growing season.
In conclusion, it is possible to overwinter geraniums in an unheated greenhouse, creating a frost-free environment that allows the plants to rest and rejuvenate during the winter months. Trim and prepare your geraniums before placing them in the greenhouse, and remember to water them sparingly. If a greenhouse is not available, wrapping them in plastic bags and storing them in a cool, dark location can also be effective.

How to overwinterize geraniums in bare-root form
Overwintering geraniums in bare-root form is a popular technique among experts and experienced gardeners. Not only does this method save space, but it also ensures that your geraniums are ready to bloom again when the right conditions come along.
Emily Clapp, a consultant at the Housegrail Society, adds, “Overwintering geraniums in bare-root form is a great way to keep these beautiful flowers alive throughout the cold winter period. Whether you have large potted geraniums or annuals, it is important to take the following steps to ensure successful overwintering.”
Here is a step-by-step guide on how to overwinterize geraniums in bare-root form:
- Before the first frost of the winter season, carefully dig up your geranium plants from the ground or pots. Be gentle to avoid damaging the roots.
- Trim the plants down to about 6-8 inches in height. This will make them easier to handle and store.
- Wrap the bare roots of each geranium plant in damp newspaper or paper towels to keep them hydrated.
- Place the wrapped geraniums in a breathable bag, like a paper bag or a mesh bag. This will protect them from drying out while allowing air circulation.
- Store the bagged geraniums in a cool, dark, and frost-free location throughout the winter. Some options include a basement, a garage, or a greenhouse.

- In early spring, about 6-8 weeks before the last frost date, bring the geraniums out of storage and inspect them for any signs of new growth.
- Repot the geraniums in fresh potting soil, water them, and place them in a sunny spot. They should start to grow and produce new leaves and blooms again.
Experts also recommend feeding the overwintered geraniums with a balanced fertilizer to encourage healthy growth. Emily Clapp says, “Proper feeding and care will make a significant difference in the plant’s ability to thrive after the overwintering period.”
Overwintering geraniums in bare-root form may seem like a daunting task, but with the right knowledge and preparation, it can be a rewarding experience. By following these steps, you can enjoy beautiful geraniums year after year, even in the coldest of winters.
When should you overwinter geraniums
If you have geraniums and you want to keep them alive for the next growing season, overwintering them is the best solution. Geraniums can be stored and kept dormant during the winter months, and then brought back to life when the weather warms up. This allows you to enjoy their beautiful blooms and vibrant colors year after year.
The best time to overwinter geraniums is in the fall, before the first frost. In most areas, this will be in October or November. Before the first frost hits, you should take the necessary steps to prepare your geraniums for the winter months.
Trim and store
To overwinter your geraniums, you should start by trimming them back. Cut the stems down to about half their original length. This will help the plant conserve energy and ensure that it survives the winter months.
After trimming, you can choose how to store your geraniums. There are a few different options depending on the conditions and space you have available.
Store as potted plants
If you have a greenhouse, conservatory, or a sunny window with plenty of space, you can store your geraniums as potted plants. Simply wrap the pots in plastic to create a mini greenhouse effect, and place them in a location where they will receive indirect sunlight. Water sparingly, as the plants will be in a dormant state.
If you don’t have access to a greenhouse or conservatory, you can also bring your potted geraniums indoors and store them in a cool, dark place, such as a basement or garage. Again, wrap the pots in plastic to create a mini greenhouse and water sparingly.
Store as bare roots
If you don’t have the space to store potted plants, you can also store your geraniums as bare roots. To do this, carefully dig up the plants, shake off the soil, and remove any dead or damaged parts. Then, wrap the roots in damp newspaper or moss, and place them in a paper bag or cardboard box. Store in a cool, dark place until spring.
Check on them occasionally
Throughout the winter months, check on your stored geraniums occasionally to make sure they are not drying out or rotting. If they appear shriveled or moldy, you may need to adjust the storage conditions.
When winter is over and the danger of frost has passed, you can bring your geraniums back to life by placing them in a sunny spot, watering them regularly, and gradually introducing them to outdoor conditions. With proper care and attention, your geraniums will bloom again, adding a burst of color to your garden or potted displays.
What is the best way to overwinter geraniums
If you are a keen gardener, you may want to keep your geraniums green and thriving throughout the winter. Geraniums are tender annuals that cannot withstand cold temperatures, so it is important to find the best way to overwinter them.
One popular method is to bring geraniums indoors and keep them in an unheated room or garage. These plants can be grown in pots or containers, so it is easy to transfer them indoors. Place the potted geraniums in a location that stays above freezing but is still cool, around 45°F (7°C) is ideal. Water the plants sparingly during the winter months to prevent root rot.
Another option is to store geraniums dormant. To do this, dig up the geraniums from the garden before the first frost. Cut back the foliage and trim the stems to about 6 inches long. Shake off any excess soil and place the plants in a cardboard box or paper bag lined with dry peat moss or vermiculite. Store the box in a cool, dark place such as a basement or cellar where temperatures stay around 45°F (7°C). Check the plants occasionally and lightly mist them with water if they start to shrivel.
If you have a greenhouse or a frost-free area in your home, you can also overwinter geraniums by bringing them indoors. Place the plants in individual pots and reduce watering. Geraniums can tolerate lower light conditions, but they still need some sunlight, so a bright spot near a window is ideal. Monitor the plants for pests and provide adequate ventilation.
Some gardeners prefer to take cuttings from their geraniums and grow them indoors during the winter. This means you can enjoy the colorful flowers without the hassle of overwintering the entire plant. Simply take 3-5 inch cuttings from the new growth of your geranium plant. Remove any lower leaves and dip the cuttings in root stimulant powder. Place the cuttings in a small container filled with moist potting soil and keep them in a warm, bright location. After several weeks, the cuttings should be ready for planting in larger pots or directly in the garden in the spring.
Overall, there are several methods to overwinter geraniums depending on your space, preferences, and the resources you have. Whether you choose to bring them indoors, store them dormant, or take cuttings, with a little care and protection, you can ensure that your geraniums survive the winter and are ready to bloom again in the spring.
