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 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.
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.
Is it okay to leave geraniums outside in 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.
Will geraniums in pots last the winter?
One of the most popular plants for containers and gardens is the geranium. Their vibrant hues and strong, well-shaped foliage are unmatched. Geraniums typically come in larger sizes in the garden center, which raises their price compared to other summer annuals.
Geraniums may be easily kept over the winter and enjoyed again the following year, unlike many of their competitors. Here’s how to overwinter your magnificent geraniums indoors if you don’t want to see them killed by frost this fall.
Methods of Overwintering Geraniums
Geraniums can be preserved in three different ways to endure the winter:
- inside in pots during the winter.
- Keep the naked, dormant roots.
- To create new plants, propagate cuttings.
Fall:
- Carefully dig out your geraniums before the first frost and pot them in 6- to 8-inch-diameter containers with lightweight potting soil. You can skip a step if yours are already in containers! Any that appear sick or diseased should be discarded.
- Reduce each plant by a third to a half. The cuttings should be saved and rooted to produce new geraniums.
- Give the pots plenty of water.
- Put the pots in a cool, well-lit area. Temperatures around 60 F in a sunny window are ideal for geranium overwintering. They struggle in dimly lit or hot environments.
Spring:
- Give your geraniums a mid-spring fertilization.
- When the threat of frost has gone, put them back outside. You have the option of leaving them in their containers or replanting them in your flowerbeds.
Overwintering Bare-Root Geraniums
Geraniums may endure winter dormancy if maintained above freezing since they have great thick roots and stems. Geraniums can also be stored as bare roots after going dormant. Take these actions:
- Carefully pull out your geraniums and shake all the soil off the roots before the first frost.
- To keep them, place them in unsealed paper bags or hang them upside-down in a cool, dry area at roughly 50 degrees Fahrenheit (a garage is perfect).
- Pull out your geraniums every a month or so and give the roots an hour or so in water to soak.
- Then let them dry completely before re-storing.
- The stems should remain solid, but the leaves will eventually all fall off. The plant is probably doomed if the stems start to shrivel as well!
- Check your geraniums in the early spring.
- Eliminate any shriveled areas.
- Lightly prune them, removing any dead tips.
- Put the roots in water that has some plant food mixed in for a few hours.
- Place the roots in potting soil and give them plenty of water.
- Put your potted geraniums in a window that gets plenty of sun or beneath a grow light. It can take them a few weeks to awaken and begin to grow!
- You can bring them outside once all threat of frost has passed.
Propagating Geraniums From Cuttings
The final alternative is to let go of your original geraniums and take care of fresh ones that were propagated from cuttings. This is how:
- Cut off sections of the branches that are three to four inches long with a sharp knife or pair of shears. Instead of a side branch, the terminal end of the stem—the very tip end—produces the best cuttings.
- Remove any flower buds, and pinch off the leaves in the bottom third of the cutting.
- After removing the leaves, sprinkle the wounds where the cuttings were made with rooting hormone by dipping the bottom of each cutting in it.
- Each cutting should be planted with peat moss, sand, or perlite in the bottom third. You can grow them in trays or in individual pots (plastic planting trays are available with a clear cover to hold in moisture).
- Set the pots on a drainage tray and give them a thorough watering, ideally starting at the bottom (fill the tray with water and allow it to soak to keep from washing away the rooting hormone).
- Use the tray’s included cover or cover your pots with clear plastic.
- Place away from the sun in a sunny window. Although they require light, your clippings cannot withstand direct sunlight.
- By wetting the drainage tray, removing the plastic cover, or sprinkling the plants and soil with a fine mist, you may maintain the moisture level of the planting medium.
- In 6 to 8 weeks, your cuttings should begin to root. You can transfer them to their own pots with standard potting soil before the beginning of the next spring.
- Your new plants will branch out if you fertilize them and prune the new stems.
How long do geraniums in pots 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.
Do I need to trim back my perennial geraniums?
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.
Will geraniums survive a frost?
Unlike Pelargoniums, which are non-hardy and typically used as summer bedding, Hardy Geraniums are herbaceous perennials that can withstand frost.
These Geraniums, known as Cranesbills, are totally hardy to H7, meaning they will survive our winters and regularly reappear in the spring. All are appealing, practical border plants that don’t fuss over their growing circumstances and blend in nicely with other plants, particularly roses. Some types are herbaceous while others are evergreen. Additionally, bees and butterflies adore geraniums.
Geraniums range greatly in size from the large, low-growing forms like Geranium sanguineum, which is about 30 cm, to the little, compact varieties like Geranium pratense, the meadow cranesbill. The main difference between the roughly 10 geranium kinds seen in the gallery below is size.
The blue, purple, pink, and white geranium blossom has interesting markings inside it frequently, as shown in the photographs below. Below are some planting arrangements, including a Geranium with a Candelabra Primula, a brilliant red Geum, and an Alchemilla mollis where the blue contrasts well with the lime green. Geraniums will cover the base leaves of Alliums, which can seem ragged even early in the season, and look good growing around Alliums. Some geraniums flower continuously from June until the first frost. Even though the herbaceous kinds wither throughout the winter and reappear in the spring, this particular variety of Geranium will return year after year.
