Geraniums can be stored while dormant as a low-effort wintering technique. With this method, zonal geraniums consistently produce positive outcomes because of their robust genetics. Other varieties of geranium may or may not survive the winter as dormant plants. Many of our grandmothers overwintered geraniums in this manner back when basements frequently had stone walls, dirt flooring, and high levels of humidity. For this strategy to work, modern basements are typically too warm and dry.
Geraniums can be prepared for dormancy by being lifted out of the ground. In chilly climates, you can choose to wait until a little frost has passed. Another benefit of a frost is that it kills insects that might be lurking among the leaves. Geraniums should be collected before a fatal frost. largely remove the soil from the roots. Plants can be pruned down by a third to a half, although it’s not required.
From the rafters in the basement, our grandparents hung their plants. Instead of rafters, use containers that support plants and enable air circulation, such as brown paper bags or boxes. Each four weeks, inspect your plants. If stems begin to shrivel, immerse the rootball for a couple of hours in a pail of water. Before putting geraniums back in their storage pots, let soil and plant surfaces dry to the point of being drip-free.
Before putting plants outside in the spring, plant geraniums. Before planting, soak the rootball for the entire night and remove any last bits of browned foliage. Be careful not to harm any growing shoots that are white or light green. Place plants near windows with lots of light to promote growth. Prior to the emergence of new leaves, stems will turn green.
Geraniums can also be potted up and placed outside in a sheltered area. If a late spring frost looks imminent, just make sure to move plants inside. Trim back any stray stems or ones that failed to leaf out once plants have leafed out and are growing outdoors.
Growing geraniums indoors is another way to overwinter them. Depending on the amount of space you have indoors, you might want to prune plants by a third to a half. Bright lighting, cool air temperatures, and water should only be applied when the soil is dry. Before taking plants inside, thoroughly inspect them to make sure you aren’t bringing insects with you.
Geraniums that have been wintered develop greater blossoms as the plants get older. In particular, this is true of zonal geraniums. Young plants are capable of producing flower heads the size of softballs. Geraniums can be kept during the winter to save money that can be used to buy other plants for your garden.
Can geraniums survive the cold in pots?
Geraniums can be overwintered inside in three different ways: as a houseplant, as a dormant bare root, or as cuttings. Your decision will be influenced by the amount of room you have indoors and the range of temperatures you can tolerate. Here is a closer examination of each method.
Overwintering geraniums as houseplants
If you want to keep the entire potted plant and have lots of room close to a window that gets bright, direct light, go with this option. A drafty west-facing window would be the ideal place for your potted geranium to spend the winter because geraniums prefer it chilly (55 to 65 F is optimum).
Wash the foliage well with your hose and repot the plant in new potting soil to prevent bringing unwanted pests from outside. You might also use insecticidal soap, which is sold in most garden centers and hardware stores as well as online. Avoid taking the plant indoors if it shows any signs of pests or illness. Only strong plants have a chance of successfully overwintering indoors.
During the winter, keep the soil wet but not damp. No more humidity is required. If the stems begin to sag, pinch them back to keep the plant compact throughout the winter. When springtime comes around, you may start fertilizing once more and transfer the plant back outside as soon as the temperature reliably rises above 50 F.
Overwintering geraniums as dormant bare root plants
This is the most typical way to overwinter geraniums, but it won’t work unless you have a dark, dry place that stays around 50 degrees throughout the winter.
First, dig up your geranium before it freezes and shake the dirt off the roots. To stop mold from forming, let the plant sit and dry for a few days before storage. Before moving onto the following phase, the roots must be completely dry.
The roots should be kept in a dark, dry place that doesn’t get colder than 45 degrees throughout the winter. Geranium roots should be kept at a temperature of 50 F. You can keep them by doing:
- It has been customary for generations to hang the plants upside-down from the rafters;
- placing them on a shelf after wrapping them in newspaper or a paper bag;
- they were put in a cardboard box.
Step 3: Every month or so, look for mold, black leaves, or limp stems at the roots. Remove any plant or root components that are harmful. Most of the stems should endure the winter in good shape. Before re-storing them if they become too wilted, give them a good bath in water and let them air dry.
Step 4: Reviving your geraniums involves cleaning them up, pruning the stems back to healthy green growth, and replanting them in new potting soil about six weeks before your final frost date. Where the new roots will grow, bury the stems two nodes deep. When you notice fresh growth in one to two weeks, keep the plants somewhat dry; after that, keep the soil moist until the plants are big enough to replant outside.
Overwintering geraniums as cuttings
If your light windowsill area is limited or you are concerned that bringing in your entire potted plant would also attract unwanted bugs, this is a nice technique to try. Additionally, it’s a fantastic way to multiply your existing geraniums.
To trim plants, you’ll need:
- a cutting edge.
- Most hardware stores and garden centers sell rooting hormone, which is sold online.
- Use little terracotta or plastic pots, or recycle a clear takeaway container for roasted chicken.
- If you don’t eat chicken, use clear plastic bags to cover the pans.
For the winter, should geraniums be pruned back?
You should prune a perennial geranium after it has bloomed all season and starts to wither. This helps the plant store energy for the spring while simultaneously keeping it dormant for the winter. This could need to happen any time between August and late October, depending on your zone. Cut perennial geraniums down to 2 or 3 inches above the soil with a pair of trustworthy shears, ideally at nodes or new growth points. Take out any more flowers or foliage. You’ll have a collection of thick stems that is really ugly. But don’t panic, your blooms will return in full bloom the following spring.
How are perennial geraniums prepared for winter?
For many gardeners, getting the perennial garden ready for the fall and winter entails different things. A smart place to start is by deciding on your degree of comfort! Methods can range from doing absolutely nothing to paying close attention to each plant’s needs. One school of thought holds that letting nature take its course is ideal, so leave the garden alone to find its own path. However, keep in mind that this may expose the garden to pests and other natural invaders like diseases. Knowing the requirements and preferences of your perennial flowers is crucial if you want to organize things among your landscape plants and be better prepared for spring gardening.
The fundamentals of closing the perennial garden:
- Fertilize not. The plant cannot prepare for the winter by encouraging new growth at this time. However, compost addition is advantageous for soil nutrition. When necessary, the plant will progressively react to this.
- Continue to remove dead and dying foliage as well as spent flowers.
- Keep dead leaves and other debris away from plant bases, especially before it begins to freeze.
- Until the ground freezes, keep watering. This is the element that has the most impact on how plants survive the winter.
- In the late fall, spread a layer of mulch or mulched leaves. Gather the leaves now! Even though the mulch shouldn’t be added until mid-November, if you start mulching leaves as they fall, you’ll be far ahead of the game. This safeguards plant crowns. Reminder: Avoid mulching bearded iris.
- Water sensitive plants thoroughly, add compost for nutrition, and construct a small chicken wire cage that you can fill with mulch or chopped leaves.
- Any plant that thrives in winter temperatures that are a little higher than yours.

In the autumn, nothing has to be done. Only the removal of dead stalks or stems will benefit these plants.
What should you do with geraniums in pots throughout the winter?
Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mold.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shriveled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Next year, how can you preserve geraniums?
Geraniums have the advantage of easily entering dormancy, allowing for storage in a manner akin to that of sensitive bulbs. This method of storing geraniums for the winter entails digging the plant up in the fall and carefully removing the soil from the roots. The roots should not be spotless, just clear of dirt clumps.
In a room with a constant temperature of roughly 50 degrees Fahrenheit, such as your garage or basement, hang the plants upside down (10 C.). Rehang the geranium plant after soaking the roots in water for an hour once a month. All of the leaves on the geranium will fall off, but the stems will still be alive. Replant the dormant geraniums in the ground in the spring, and they will come to life.
Should geraniums be pruned in the fall?
reducing after blossoming After flowering, early-flowering perennials like geraniums and delphiniums are pruned to almost ground level to promote new growth and late-summer blooming. Then, in the fall or spring, these are again pruned.
When should geraniums be wakened from dormancy?
Dormant, full-size geranium plants can be overwintered in the same way as animals hibernate during the winter and then come out of it in the spring.
Steps to Overwintering Dormant Geraniums
- Before the first frost, transplant the geraniums into containers and prune the plant back by about half. Dehydrate the soil in the pot.
- Put a paper bag on top of each plant and turn it over.
- Containers for dormant plants should be kept in a garage or basement that is chilly, unheated, and slightly damp.
- Every few weeks, check the geraniums to make sure the stems and leaves are not shriveling. Spray them with water or mist the roots if they start to show signs of drying out. After that, let the plant thoroughly dry before putting it back in the paper bag.
Reviving Dormant Geraniums
- Relocate your dormant geraniums to indirect light around 6–8 weeks before the final anticipated frost.
- Trim any dead leaves from the plants, and cut stems back to a healthy, green growth.
- Give the potted plants a good soaking and some fertilizer that has been diluted.
How should outside plants be prepared for the winter?
Do you still recall the bindweed that took over your raspberry patch? Or the Himalayan blackberry that is growing towards the edges of your garden? Dealing with those outlaws at this time is necessary. They can be dug up and thrown in the garbage or covered with tarps or garden fabric.
Avoid the temptation to simply move invasive weeds to another area of your garden because the majority of invasive weeds can survive in a compost heap or weed pile. The only method to stop invasive plants from springing up again and interfering with the crop the next year is to entirely remove them.
Hardy Geraniums vs. Pelargoniums
Pelargoniums should not be confused with hardy geraniums. You might be wondering what makes a geranium different from a pelargonium. Similar to some siblings, they are both members of the same plant family, but they could not be more unlike.
Pelargoniums cannot withstand frost, while hardy geraniums can. Pelargoniums are usually treated as annuals and replanted each year, but true hardy geraniums are perennials that grow back every year. Pelargoniums die in the winter.
Prune your Hardy Geraniums
Your sturdy geraniums will look their best and promote new growth if you prune them properly. By correctly pruning your hardy geraniums after the blooming season, you can encourage repeat blooming. The majority of geraniums can be cut back twice in a single season, which allows them to bloom at least three times.
When to Prune
Your hardy geraniums should be pruned in accordance with the season you are in. Rozanne will require various cuts in the spring, summer, and fall. To maintain your blooms rich and healthy, mark your calendar and adhere to our seasonal trimming recommendations.
What tools you need
Your geraniums may be pruned fairly easily. All you’ll need is the ability to prune, a pair of sharp pruners, your favorite mulch, and your favorite gardening gloves. Watch this video to learn more about pruning strategies in detail.
How to prune
You shouldn’t be concerned that pruning your flower’s back will harm her. The majority of hardy geraniums require trimming to promote new growth and prevent them from encroaching upon other plants.
Trim the plant back to within a few inches of the ground or to about an inch above the main stem once the flowering is completed or you find old growth. Remove any brown stems or yellow leaves after that by going inside.
Soon after trimming, more leaves will start to appear. Some resilient geraniums even have the ability to blossom again. Maintaining correct pruning on your plants encourages new development and keeps them from spilling out throughout your landscape.
