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.
Can geraniums be kept in pots during the winter?
Geraniums are frequently planted in containers, which is a fantastic option if you want to overwinter them.
In the fall, before the first frost, if your geraniums are already in pots, you can simply relocate the pots under cover into a sunny, airy, and frost-free location, such a greenhouse or conservatory.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “the best area would be a greenhouse and the ideal climate would be to have a heater in place to preserve temperatures above freezing when frost does threaten.” (new tab opens) (PAGS).
You can dig up, repot, and move the pots under cover if your geraniums were grown in a border.
Geraniums should always be pruned back before being brought indoors, whether they are already potted or have been removed from the border and repotted, according to David Taylor of PAGS.
“First, you should prune your plants back by roughly two-thirds; if lifting from outside beds, they could need to be pruned down by three-quarters or perhaps more. Do this pruning only while the roots are dry; otherwise, the remaining stems will wither.”
‘Also, get rid of any diseased, damaged, or dead sections you see. Make sure they are bug-free before bringing them inside for the winter,’ adds Emily Fernandes, a Californian small-space gardener and HouseGrail expert (opens in new tab).
Geraniums are best kept in a semi-dormant state while enclosed, as this means they won’t need as much water or food. “Place them in a partially sunny area, water them every two to three weeks, and maintain a humidity level of about 50%.” According to Emily Fernandes, a consultant at HouseGrail, “they go dormant over the winter like most other plants to store their energy for the growing season” (opens in new tab).
Pruning Geraniums After Winter Dormancy
The optimum time to prune geraniums is in the early spring if you put them into dormancy for the winter or if you live in a region where they lose some of their leaves over the winter.
Take off all of the geranium’s brown and dead leaves. After that, remove any diseased stems. Squeezing a healthy geranium stem will feel firm. Cut down the geranium plant by one-third, paying particular attention to stems that have begun to turn woody if you want a less woody and lanky plant.
Cutting Back Geraniums That are Wintered Alive
The best time to prune geraniums is in late fall or right before you bring them inside, if you intend to bring them indoors. If you do not put your geraniums into dormancy for the winter and they remain green in the ground or in containers year round.
Trim the geranium plant back by one-third to one-half, paying special attention to lanky or woody stems.
How to Pinch Geraniums
In order to make the plant grow more bushy and compact, geraniums are sometimes pruned. You can pinch either newly purchased bedding geranium plants or geraniums that have been overwintered. Pinching of geraniums begins in the spring.
When a stem on a geranium plant reaches a few inches (7.5–10 cm), cut off 1/4–1/2 inch (0.5–1.5 cm) of the stem with a sharp pair of scissors, or even with your fingers. Repeat over all stems. The geranium will be forced to produce two new stems off of the original stem as a result, which will result in a bushier, fuller plant. If you prefer, you can keep pinching geraniums all throughout spring.
Geranium pruning is simple and improves the appearance of your plant. You may enjoy your geraniums more now that you know how to prune geranium plants.
When should I trim my geraniums back?
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.
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.

Do I need to remove the dead flowers from my geraniums?
Of course, removing all the dead blooms will immediately improve the appearance of your plants, but there are additional benefits to understanding how to deadhead geraniums.
Your geranium will focus all of its energy on producing seeds if you leave the dead flowers on it rather than producing new blooms. By cutting them off, the plant may focus its efforts on developing new blossoms. Therefore, if you keep up with the deadheading, you’ll have enough of new flowers all summer long for your hanging basket ideas or other displays.
Additionally, keeping them organized in this way enhances the air flow around the plant. This lessens the risk of the widespread fungus illness botrytis blight.
How can leggy geraniums be reduced?
I took a sampling of stems out on the patio so you could see what I was pruning off.
4. Keep trimming stems to establish the framework for the plant’s growth.
5. While pruning, don’t forget to take a step back and survey the plant. Any stems you don’t like should be cut off (I always end up cutting off a few more after I think I’m finished!). & prune any tips that are needed.

Iowa’s AMES
Beautiful plants like geraniums offer color and life to any landscape. They are not prepared to endure the hard winter weather, though. Geraniums can be brought indoors to overwinter and then replanted in the spring.
Horticulturists at ISU Extension and Outreach can assist with your inquiries regarding overwintering geraniums and how to keep them healthy during winter weather.
How can I overwinter geraniums indoors?
By obtaining cuttings, potting up individual plants, or preserving bare-root plants in a cool, dry place, geraniums can be overwintered indoors. Before the first fall frost, remove plants from the garden (or take cuttings).
How do you take geranium cuttings?
Take three- to four-inch stem cuttings from the terminal ends of the shoots using a sharp knife. Pinch the bottom leaves off each cutting before dipping the base in a rooting hormone. Insert the cuttings into vermiculite or a mix of perlite and sphagnum peat moss as a rooting media. Rooting containers that have drainage holes on the bottom are pots and flats. Just enough to allow the cuttings to support themselves should be inserted into the media. Water the rooting media once all of the cuttings have been placed.
Place a clear plastic bag or dome over the cuttings to stop the plant foliage from wilting after allowing the medium to drain for a few minutes. The cuttings should then be placed under bright light—not direct sunshine. In six to eight weeks, the cuttings should begin to root. Remove the cuttings from the rooting media after they have healthy root systems and plant each rooted cutting in a separate pot. Until spring, keep the potted plants in a window with natural light or under artificial lighting.
How do you overwinter geraniums as potted plants?
Each plant should be dug up carefully and put in a big pot. After giving each plant plenty of water, set the geraniums in a window with natural or artificial light. Geraniums prefer a cool environment indoors. The ideal temperature range is between 60 and 65 degrees Fahrenheit during the day and a little bit lower at night. Plants need watering around every two weeks. By the end of winter, geraniums are likely to grow tall and lanky. Trim the plants back in March. Reduce the geraniums by a third to a half. Within a few days, the geraniums will start to grow once more, and by May, they should be beautiful specimens.
How do you overwinter geraniums as bare-root plants?
The geraniums should be carefully dug out before the first fall frost. Remove the plant’s roots’ soil by shaking them. After that, put one or two plants in a sizable paper bag and keep it dry and cool (45 to 50 degrees Fahrenheit). It might be appropriate to use an indoor porch or an unheated bedroom. Hanging the plants upside-down in a cool, dry area is a another (somewhat messier) option. Eventually, the leaves and the shoot tips will wither away.
Trim or prune each plant in March. Get rid of all the dried-out, lifeless stuff. Return to firm, green, living stem tissue through pruning. After pruning, pot the plants and give them plenty of water. Put the potted geraniums in a window with natural light or next to a light source. March pruning and potting of geraniums should result in lovely plants that may be put outside in May.
How should I get ready for winter with my perennial geraniums?
Avoid cutting geranium Rozanne sat down again. During the winter, her greenery transforms into a cozy blanket that wraps her up and keeps her safe. When the cold is gone and spring once more welcomes us, Rozanne will remain hidden and come out on top.
Clean Around Her And Add Mulch
By moving your hands through the plant, get rid of any dead leaves that are close to or on Rozanne. Remove any leaves that are moldy or moist as well. Mulch will add further winter protection.
Let Her Rest
Wintertime doesn’t call for much fuss for Rozanne. Give her a thick layer of mulch in the late fall, then allow her to hibernate over the winter. She will be shielded from the frost by the mulch.
If She’s In A Container, Move Her
If your Rozanne is already planted in a container, you can relocate her to a sunroom or another location that will receive some shade during the day, and when it gets chilly or windy, you can take her inside a shed or another building.
Don’t Stress!
Rozanne is a tough cookie and will return in the spring to display her lovely colors. Rozanne can be overwintering if you live in a particularly cold climate by being taken out of your garden. She is a resilient plant that can survive the tougher winter months pretty well, so this isn’t necessary, but it is a choice. After all, she is adored for a variety of reasons, including how durable she is!

When should plants be pruned back during the winter?
When in the fall is the greatest time to cut back? A: “Before the fresh new growth starts and when they start to look too ratty for you,” according to Sarah. Wait until after the plants have had multiple hard frosts to prune frost-sensitive plants to be sure they are dormant.
How should I care for my geraniums during the winter?
Over the winter, store your geraniums. 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.
Do geraniums regrow after the winter?
Trim the geraniums back to little bushes as winter is approaching, then bring them inside. The plant will continue to thrive all winter long under a grow lamp suspended above it or in a sunny, south or west-facing window. In order to prevent root rot, winter geranium care essentially calls for light and restricted watering. Wait to fertilize until the spring when new growth starts.
Take cuttings instead, then remove the bottom leaves off the stem. Insert the cutting into damp potting soil, cover at least one leaf node (where the new roots will emerge), and then swirl in rooting compound. Keep the potting mix evenly moist and put it in a well-lit area. In three to four weeks, new roots begin to form.
By digging up or removing the plants from their pots, you can also store bareroot geraniums for the winter. Shaking off the soil and hanging the plants or putting them upside-down in a box are two suggestions made by Master Gardener Betty Hensley. The bareroot plants should be kept at 50 to 60 degrees throughout the winter before being potted six to eight weeks before the last day of frost. Use sterile scissors or anvil pruners to trim the stems back to new, green growth. In two weeks, new growth will start to show, and when the outside temperature reaches 60 degrees or higher, the geraniums will be ready to go back into the garden.
