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 perennial geraniums need to 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.
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.
Prune the geranium plant back by one-third to one-half, focusing on stems that are woody or leggy.
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.
After flowering, what should you do with 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.
How should a perennial geranium plant be cared for?
There is no “one size fits all” care for geraniums because there are so many different kinds available in the trade. Perennial geraniums are fortunate to be hardy and versatile. Geraniums may thrive anywhere from full sun to partial shade. Many cultivars can also thrive in greater shade, though they can produce fewer flowers. Additionally, perennial geraniums enjoy well-drained soil and may complain if it is too damp.
Geraniums benefit from having their stems cut back once they’ve finished blooming. Those plants that bloom on longer stems can be pruned back to their basal foliage development. This will prevent them from looking too disorganized and encouraging fresh development. On some species, it could also give you a scattering of rebloom.
How do you maintain the flowering of perennial geraniums?
How to Increase Hardy Geranium Blooms
- Give the Right Lighting. Make sure your blooms are receiving enough sunlight.
- Maintain Soil Moistness. Keep the soil damp but not soggy.
- Detach any leggy growth. Midsummer is the time to prune the plants.
- Give Your Plants Food. To promote blooming, apply a fertilizer strong in potash.
Should I prune every perennial in preparation for winter?
Warm-weather gardeners can use the fall and occasionally even the winter as additional growing seasons. However, October is a perfect time to start garden cleanup if you live somewhere with harsh winters. The phrase “four seasons of interest in the garden” is often used, yet perennial plants hardly ever fall within this description. The majority of perennials lose their beauty as the weather becomes colder, and any plant that is sick, infested, or otherwise unhealthy should be trimmed back and removed rather than let to survive the winter.
But if perennials are cut too late in the growing season, some of them just don’t do well. They depend on their fallen leaves’ wintertime protection to help them live. It is advisable to prune these 43 plants in the spring.
Tip
Even if the plant would ordinarily benefit from being left standing during the winter, it is recommended to trim away and discard the afflicted foliage when plants have obvious signs of bacterial or fungal disease. Since the bacteria might spread and infect other plants, you don’t want infected plants to stay over the winter. The same is true with sick leaves and other ground-covering debris. For those plants that benefit from winter protection, remove this material and cover the area with a fresh, sterile mulch.
How are geraniums prepared for 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.
How should geraniums be cared for over the winter?
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.
Perennial geraniums live how long?
You may divide geraniums into two primary groups. There are real geraniums, also known as cranesbill and hardy geraniums. They are frequently mistaken for common or scented geraniums, which belong to the related but distinct genus Pelargoniums. Compared to true geraniums, these offer a considerably more impressive flower display, but they are more difficult to maintain over the winter.
Only USDA zones 10 and 11 are suitable for growing pelargoniums, which are native to South Africa. They are typically only grown as annuals in most countries, despite the fact that they can live for many years in warm regions. They may also be raised in containers and brought indoors to overwinter. As long as it doesn’t get too cold, the common geranium can live for many years.
On the other hand, true geraniums can be cultivated as perennials in a considerably wider range of conditions because they are far more cold hardy. For the most part, USDA zones 5 through 8 are winter-hardy. Some types can withstand the hotter summers in zone 9, while others can endure winters that are as chilly as those in zone 3, at least for the roots.
As long as it is properly cared for, geraniums can live for many years. Additionally, they are easily overwintered. Some other kinds, like the biennial Geranium maderense, only live for two years but can withstand most winters.
In order to answer the question “how long do geraniums live,” it is important to consider both your location and the sort of geranium plant you own.
When To Cut Back
Perennial plants’ leaves will start to wither as soon as the first mild frosts start to fall on them in the middle to late fall. When this happens, it is the perfect moment to start pruning plants.
The process can start before the entire plant has turned brown or withered. In fact, the entire plant can be cut back once the flowering cycle is finished and the blossoms have gone.
How To Cut Back Perennials
Almost all perennial plants can be pruned back in the same way. Start by trimming the plant to a height of 3 to 5 inches above the earth. Trim off all of the stems and foliage with a good set of pruners or hedge trimmers.
The “sharp” aspect is crucial since, in the fall, many plant leaves and stems can be stringy and difficult to cut if your blades are dull. For this job, hedge trimming shears function incredibly well since they can make big, rapid cuts. (OARA Garden Hedge Shears is the product link.)
There are various benefits to leaving the plant slightly above the ground. First, the plant can get some insulation from the surviving foliage over the winter.
However, keeping the plants above ground also makes it easier for a gardener to identify the locations of perennials. It could be challenging to identify where to put plants and mulch now and in the spring if you cut them all the way to the ground.
Speaking of planting more plants, now is an excellent time to divide any that have outgrown their space. Simply plant the extra seedlings after dividing them to help prepare the beds for the following year. (See How to Quickly Divide Perennials to Generate Free Additional Plants!)
What To Do With The Clippings
The plant matter that is being cut back is ideal for the compost pile as long as it is disease-free. To hasten decomposition, it is a good idea to shred everything before putting it to your pile.
If you don’t have access to a chipper or shredder, just cut up the foliage with your lawnmower before adding it to the pile.
Some Perennials To Not Cut Back
Leaving certain perennials to winter with their spring and summer growth intact is optimal. While some plants’ leaves and wasted bloom heads shield and provide food for wildlife throughout the chilly, desolate winter months, other plants’ development is required for protection.
When it comes to protecting birds and other small creatures throughout the winter, ornamental grasses top the list. For animals, leaving them up is preferable to cutting them back in the fall.
They also do a superb job of bringing interest to the frequently barren winter landscape.
Coneflower, black-eyed susan, and shasta daisy stems and seed heads are frequently left in gardens all winter long to provide food for foraging birds.
And Don’t Cut Back Those Mums!
Always try to preserve as much of the leaves as possible when dealing with garden mums. The plants require the extra foliage to help shield them from the wrath of winter due to their late fall flowering.
Here’s to pruning your landscape’s perennials and healthy, profusely blooming plants the next year!
Can the leggy geraniums be pruned?
Not sure what to do with geraniums that are too leggy? Aim to prune. You should prune your spindly geraniums by approximately a third before bringing them inside (often in late November). Make sure to get rid of any stems that are sick or dead as well. Geraniums that are too lanky can be pruned to keep them from overgrowing and looking unattractive.
Another method for tying up lanky plants is pinching. This is typically done to mature plants to encourage bushier growth. Once new growth has reached a couple inches (8 cm) high, pinch out around 1/2 to 1 inch (1-2.5 cm) from the tips. This can be done during active growth or soon after trimming.
