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.

How can I tell if my geranium is a perennial or annual plant?
Are geraniums perennial or annual plants? Are you one of those customers at the garden center who has to pause and clarify the difference between an annual and a perennial? Unless gardening is our one and only true love, the truth is that we have all likely experienced it at some point.
A seasonal plant dies after going through one life cycle. A perennial plant endures for at least two years. Depending on where and how they are grown, geraniums can be either annuals or perennials.
The Latin term for geranium is pelargonium. These plants are typically grown as annuals since they cannot endure cold. However, they can be grown as perennials with a few simple techniques. In the following sections of this post, let us share a few of those tips with you.
Do geraniums grow back after the winter?
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.
Do geraniums in pots reseed?
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.
Can geraniums survive the cold outside?
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.
How long do geraniums last?
My geraniums are no longer blooming. I fed them, but it was ineffective. What’s the issue?
You might be feeding them too much. Pelargoniums, a genus of geraniums native to the Mediterranean, flourish in full sunlight and relatively infertile soil. Overfeeding can be the issue if you have a lot of foliage growth and the plants appear healthy. For a while, stop giving them food. But if your plants are becoming older and their stems are getting lanky, it might be time to propagate. Although they can live much longer, geraniums typically only bloom for two years on average before becoming woody and losing their blooming ability. Thankfully, geranium propagation is simple. Simply cut stem tips with at least two pairs of healthy leaves from a four-inch stem. Cut the stem at the lowest point, dunk it in hormone rooting powder, and then plant it in a mixture of half sand and half peat moss. In around three weeks, repot in ordinary soil after providing adequate watering and covering with plastic to assist preserve moisture. Sticking the cutting in water and letting it grow roots before potting is a simpler method.
How can winter geraniums be kept alive?
Geraniums can live for the majority of the winter without soil, which sets them apart from most annual flowers. Due to their thick, succulent-like stems, geraniums may withstand prolonged periods of dryness if they are handled correctly to prevent illness.
How to Store Geraniums
- Before the first harsh cold of the season, remove the plant from its outdoor container and gently shake the soil from the roots.
- Reduce the plant by roughly 50%, taking care to remove any unhealthy-looking growths, flowers, or dead leaves.
- For the winter, pick a cool, dark spot, such as an unheated basement, garage, or shed. It is crucial that the temperature stay above 45 degrees F.
- The plant should be hung or put in paper bags. If you decide on using bags, don’t close them too tightly; you want some air to flow through them. When geraniums are overwintered, mold can grow on them. When hanging plants, The Spruce advises leaving enough space between them so that air can flow around them.
- Put tags (loosely) around the roots of your plants to identify them by color, or group them according to color while storing them.
Care for the Dormant Geraniums
- Take the plants out of the bags and give the roots a 1- to 2-hour soak in warm water. I’ve seen some professionals advise doing this once a month, while others advise doing it a few times during the winter. Before putting the plant back in the paper bag, give it time to completely dry. THIS IS ESSENTIAL.
- Even if the leaves are withering, check the geranium stems every two weeks to make sure they remain firm. You should discard any plants with withered stems right away. Anything with mold on it should be thrown away.
Reviving After Dormancy
- Trim any dead stem tips, and get rid of any roots that are too lengthy.
- Before potting, bare root plants can be given an extended soak in water to rehydrate the roots.
- Six weeks before the last frost, plant geraniums.
- When planting, bury the plant two leaf nodes deep in moist potting soil to encourage root development.
- Give them plenty of water.
- To reintroduce light and encourage fresh growth, place the newly planted geraniums in a sunny window. After inactive storage, it will probably take the plants 2-4 weeks before they begin to grow.
Will my geraniums survive the winter indoors?
Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
Bring Inside as Houseplants
You can bring your potted geraniums (Pelargoniums) indoors for the winter if you have space for them in a sunny place.
While they require sunlight, they thrive in temperatures between 55 and 65 °F (12-18C). I have tremendous luck keeping the air around them a touch colder than the rest of the home with a west-facing window that is slightly drafty.
Dig Up and Repot if Desired
To make sure they are content, healthy, and bug-free, some preparation is needed.
- Before the first frost, dig up and container your geraniums if they are in the ground.
- If they are already in pots, you can repot them if you want, but first perform a rigorous pruning and a bug inspection (see below).
- Trim any extremely long roots or any unkempt root balls before potting.
- Put flowering plants in containers using potting soil made for them.
Hard Prune
- Cutting back the entire plant by between one-third and half is an usual recommendation.
- Any dead, broken, moldy, sick, or diseased pieces should also be taken out.
- If the plant is otherwise good and healthy, you can try keeping any buds or blossoms even though this harsh pruning is ultimately ideal.
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.
Go dormant geraniums?
Full-size, dormant geranium plants need to be tucked away for the winter and then retrieved in the spring. Geraniums in pots should be kept in a cool, unheated, somewhat wet basement.
Check Every Few Weeks
Verify your geraniums’ leaves and stalks every few weeks to make sure they 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 the paper bag back on.
Can geraniums survive the winter in an unheated greenhouse?
- 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.
