Large, lovely blossoms on a trailing geranium that I keep in a hanging basket. If at all possible, I want to keep this through the winter. What should I do to keep it going all winter? I always buy a new one the following year if it breaks, but this one is so lovely that I would rather to preserve it.
Answer:
Geraniums are one of the plants that can frequently be transported safely through the winter, but the trailing kind is trickier to transport than the more succulent varieties, which have thick stems filled with moisture.
When there is a chance of frost, move it inside (or into the garage) for the time being. Once the day warms up, move it back to a bright area. This will preserve it for as long as possible in the optimum condition. If it has healthy food reserves in its stems and roots, it will have a higher chance of surviving when you finally need to move it indoors. It is currently storing food, and based on how effectively you described its flowering, it is in an environment that is assisting in its growth and the storage of those food reserves.
You might need to keep it indoors more as the temperature drops. The optimum indoor place for it will be a cool room that receives light from the south or east (40 to 60 degrees at night). To disperse the light and slightly lessen its intensity, hang sheer drapes in the window. To help your plant preserve its food stores, keep the room as cool as you can during the day and allow it to get rather cool at night (as low as 40 degrees). The stored food is used more quickly in warm weather. Additionally, keep an eye out for insect attacks. The natural predators that help manage hazardous insects when your plants are outside are absent from the indoor environment. Early problem detection will allow you to take corrective action and keep your plants healthy. By placing the plant in the bathtub or sink and gently washing the insects off the plant with a stream of water, many insects and harmful arthropods (spider mites and aphids) can be controlled. Other pests might need to be eliminated manually with a cotton swab dipped in horticultural oil or insecticidal soaps, which are best used in the bathtub.
You can replant the geranium outdoors in the winter on warm days in a well-lit yet shaded area. The leaves will burn if exposed to direct sunlight after being indoors under low light. Make sure to keep a close eye on the plant to prevent drying out. It will utilize water more quickly on warm winter days than on cool indoor days. You can give the geranium a fertilizer for flowering houseplants along with some irrigations if it keeps growing and otherwise shows signs of good health (leaf color, flower production). This will help the plant stay healthy and enhance the amount of food that can be stored. However, fertilizer can make the plant worse if it appears to become dormant, stops flowering, or grows slowly. In that case, give it nothing but water and, if feasible, make sure it gets more light throughout the day or lower the temperature by placing it in a cooler place.
Remove the plant from the pot in the spring as growth picks up and you get ready to put it back in its outdoor home. Then, gently tease or wash the soil from the roots before adding fresh potting soil.

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.

Are perpetual trailing geraniums?
Ivy leaf geraniums, which grow quickly and have vivid colors, are the star of any hanging basket design.
Pelargonium peltatum, a member of the Geraniaceae family, is sometimes referred to as an ivy leaf, trailing, or cascading geranium.
P. peltatum, a cool-climate-adapted perennial herb native to South Africa, was imported to Holland and England by 1704. Only Zones 9–11 are they winter hardy, but due to their quick growth and simple multiplication, they were rapidly utilized as an annual, and they still are.

Plants with prodigious growth patterns can spread dramatically to a height of up to six feet, and they bloom all summer long in cascades of bright color.
Some species of this plant have variegated foliage with flowers that bloom in colours of apricot, burgundy, lavender, orange, pink, purple, red, and white. The five-lobed, bright green leaves are similar in shape to those of ivy.
They are an eye-catching addition to Mediterranean gardens, beds and borders, window boxes, hanging baskets, planters, and containers. In hotter climates, they can even be used as a ground cover.
When compared to zonal variants, the inflorescence, or umbel-shaped clusters of flower heads, are looser in shape and density.
Greek pelargos, meaning stork, is the origin of the word pelargonium. Additionally, the set fruit has a stork-like appearance, just like its near relatives the garden geranium and the cranesbill geranium.
Can geraniums be kept for the next year?
Amazingly, annual geraniums (Pelargonium hybrids) thrive and flower wonderfully from spring till frost with little effort. The next spring, these resilient tiny plants will take off and grow once more if you dig them out in the fall and store them in a cardboard box or paper bag for the winter. Learn how to preserve your geraniums over the winter so you can enjoy them year after year by watching our video and reading the article below.
Geraniums can they grow back after the winter?
Knowing how to overwinter geraniums is very useful for gardeners since it can help them save money and extend the life of particular varieties they enjoy.
Pelargoniums, sometimes known as geraniums, are mainstays of the summer garden. Geraniums are ideal for adding cheer and long-lasting color to hanging baskets, containers, and borders since they come in a variety of colors and flower continually as long as they are deadheaded.
However, when making your job list, you might consider including them as one of your winter garden ideas.
When growing frost-sensitive plants, planning a winter garden is crucial. Geraniums are perennial plants that put on a long display, but they are frost tender, which means they won’t survive harsh winters. If you are interested in cultivating geraniums, you must learn how to overwinter them.
Geraniums are South African natives that thrive in the heat and can withstand periods of drought with little water.
Pelargoniums, sometimes known as geraniums, may live in USDA zones 7 to temperatures of -12oF (0oC) if they are sheltered. They are hardy in climates between 20oF and 50oF in zones 9 through 12. They need to be sheltered in these conditions because, while they can withstand brief frosts (temperatures slightly below freezing), they cannot withstand prolonged exposure.
The Pelargonium genus contains a wide range of cultivars, all of which are categorized as delicate perennials. According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “this means that they are not cold hardy as the majority of the founding species come from the warmer climbs of the Southern Hemisphere.
Perennial plants are able to flourish for a number of years, however in the UK this would mean that they would also need to be sheltered from winter wet and damp in addition to frost.
Geraniums can be cared for like annuals by being dug out in the fall, composted, and then replaced with fresh plants the following year. The appropriate care and attention, however, will enable you to winterize geraniums, keeping them alive throughout the winter so they can bloom once more the following year.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “Keen enthusiasts keep their pelargoniums in growth during the winter and continue to feed and water but a few key points can be undertaken by anyone to keep your pelargoniums (geraniums) alive throughout the winter” (opens in new tab).
Pelargoniums are known as geraniums, but these plants are not the same as hardy geraniums or cranesbill, which are a different kind of plant and don’t need to be overwintered.
Do geraniums survive the cold outside?
- Make sure you thoroughly inspect your geranium plants before bringing them inside for the winter. Look for symptoms of pests and illnesses like rust and remove any dead leaves or wilting blossoms. Only zonal pelargoniums are impacted by this, but it is becoming more widespread. It arrived in the nation for the first time in 1968, and it does best in the moist summer or fall months. Fortunately, it doesn’t seem to spread to the plants quickly and is simple to treat, so merely plucking the afflicted leaves is an effective management. You might also consider using the fungicide Dithane 945 as a spray.
- Placing your overwintering plants somewhere bright and sunny will help them retain their need for light throughout the winter. Your plants will receive 50% less light if they are placed more than three feet from a window!
- Because your plants continue to thrive throughout the winter, keep the roots moist. While geraniums frequently survive droughts, they rarely flourish. Show plant growers take special care to keep the roots of their plants damp but never soggy during the winter.
- Ventilate as frequently as you can to maintain a dry environment surrounding your plants. Your plants will turn into a moldy, rotting heap if you don’t allow the air to circulate. The greatest electric fan heaters are those that operate automatically since they circulate air while simultaneously raising air temperature.
- Geraniums are fairly inexpensive to overwinter in the greenhouse because they only need to be kept frost-free. To keep temperatures above freezing, however, we do advise utilizing a heater. Set the thermostat on your heater to 5C, which is 41F. The plant will not survive if the stems become frosty! The winter months are a great time to store your delicate pelargoniums in porches, sunrooms, or conservatories.

Can geraniums be kept in pots during the winter?
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.
