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 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.
How are perennial geraniums 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.
Should I prune hardy geraniums to prepare for winter?
Hardy geraniums can be grown in the sun or the shade in moist but well-drained soil. After flowering, prune back the plant to promote a second flush of blooms. Hardy geraniums wither in the fall and reappear in the spring. Plants will continue to grow well for several years if they are mulched annually with leaf mold, well-rotted compost, or horse manure.
When and how should I prune geraniums?
Geraniums and pelargoniums are undoubtedly resilient and simple to grow, however they cannot be considered “no maintenance plants.” Giving them a hard prune at the end of the summer, when the flowering is winding down, is an excellent idea to prevent them from getting too leggy. In March or April, Jane advises cutting back geraniums and pelargoniums by a third to a half. The plants will grow quickly in the spring, bush out attractively, and produce a magnificent flush of blooms.
Don’t discard pruning cuttings; they make excellent propagation materials. Trim them to a length of 10 cm, remove all but a few of the lowest leaves, and set them aside so the ends can dry out. The cuttings may be potted up after a couple of days, and you’ll have some lovely new plants for your space come spring!
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!
Do I need to remove the dead geranium flowers?
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.
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.
What is the lifespan of perennial geraniums?
One of the most dependable types of garden flowers is the geranium (Pelargonium spp.). Around the world, they are grown as indoor plants, as garden annuals in USDA plant hardiness zones 2 through 8, and as perennials in zones 9 through 11. If given the right care, a common geranium can live for 40 years or longer. The most frequent causes of geranium death are overwatering or underwatering, insects or illness, and cold snaps. They might eventually grow long and unsightly, at which point they should either be replaced or removed.
What kind of plant is a perennial geranium?
A variety of colors can be seen in the leaves and flowers of perennial geraniums. Pink, purple, red, burgundy, blue, and white are among the flower’s colorations. Veins in blossoms are frequently darker in tone, giving petals a whisker look. The blooming season for many hardy geraniums runs from spring to July. This group includes geranium ‘Max Frei,’ a kind of bloody cranesbill (Geranium sanguineum), and wild geranium (Geranium maculatum). Some cultivars, such as Rozanne or Geranium ‘Johnson’s Blue,’ bloom continuously.
The split leaves of hardy geranium plants add a wonderful texture to landscape designs. Green, burgundy, gold, or almost-black leaves, like those of the cranesbill geranium variety “Dark Reiter,” are possible leaf hues (above). Some geraniums, like the natural wildflower Geranium maculatum, have vibrantly colored leaves in the fall that range from orange, gold, and crimson.
Hardy geraniums come in a variety of sizes, from 6 inches to more of a knee-high, 18-inch plant. While some have stems that spread and creep their way across the garden over the growing season, others produce neat tufts in a planting bed. From Zones 5 to 9, perennial geraniums are typically hardy.
How are geraniums prepared for 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.
