Seeds, stem grafting, semi-ripe wood cuttings, and root division are all methods used to multiply hardy geraniums.
using seeds:
Gather them in the summer and store them for the following growing season, which is late spring or early summer.
By stem rooting:
- You may root stems at any time of year, but make sure to do it in water.
- Make sure to take stem cuttings from just below the node and use a sharp knife for it in order to grow healthy and robust roots.
- Cut off the bottom leaves and blooms as well (f there are any).
- In a protected area of the garden or on a sunny windowsill, where it receives 2 to 6 hours of sunlight, place the cuttings in water in an opaque container.
- Water should be changed every few days.
- In 3 to 4 weeks, stem cuttings typically start to produce roots.
- Plant the roots in soil when they have grown 1 to 2 inches deep.
From cuttings of semi-ripe wood:
- Hardy geraniums can be propagated from semi-ripe wood cuttings in the summer.
- However, it can be seen anywhere between mid-summer and mid-autumn.
- Select stems with a hard, older base and sensitive, green tips for cuttings from the current year’s growth.
- When the cuttings are mature, only transplant them to the earth after planting them in a light, sandy potting mix.
based on root divisions
- The ideal seasons for growing cranesbills from root divisions are autumn and spring.
- Geraniums can be grown from this procedure in the same way as semi-ripe wood cuttings are grown.
watering
Really, geraniums are quite simple to maintain. Once they are established, they don’t need watering unless there is a really dry spell. In containers, geraniums will require routine watering.
cutting back geraniums
You can prune geranium kinds that bloom in late spring and early summer to get a clump of new leaves for the remainder of the growing season.
While some types flower all season long, others start to slack off in the middle of the summer. Here, getting a standard haircut pays well. Cut all the leaves off at the ground level (or to where you can see some fresh new leaves have started to emerge). The plants would appreciate a watering with seaweed fertilizer and, if you have any, a mulch of garden compost, and hopefully, you will have a new flush of flowers in a few weeks. To avoid having to deal with the close-cropped appearance while on vacation and to be able to return to some lush new growth, I attempt to complete this task just before I leave.
Use the “Chelsea Chop” in late May to assure a succession of blooming throughout the summer if you’re a tough cookie. Choose a few plants (perhaps those that are prone to falling over along a route) and shear them back to half their height just before they are due to blossom. As a result, they will flower a few weeks later than their neighbors and become stronger and stockier as a result.
propagating & dividing
Additionally, geraniums are incredibly simple to grow. After two or three years, you might notice that they are pushing out their neighbors. The time to use a fork to dig up a few new clumps that are encroaching on your property in the spring.
You might notice the center is beginning to seem a little woody and less floriferous after around five years. It’s time to remove the entire clump and divide it using a back-to-back fork method. For greater flowering the next year, remove any old, woody portions from the center and transplant the new, fresh clumps. Even so, you might have some extra parts to share with pals.
taking geranium cuttings
Cuttings are simple to perform and will produce superior plants. One of the plants whose growth and flower density are actually greater from younger stock is geraniums.
If you take a number of geranium cuttings in April, they will be ready for replanting in a month and will be in full bloom in three. Now is the time to propagate your geraniums so that you have gorgeous pots, aromatic foliage, and velvety petals that you may pick all through the summer, fall, and into the next winter.
Reduce the size of your geranium plant by two-thirds, making sure to cut right above any lateral buds or nodes that may develop buds. Your cuttings will be built on these stem tips.
With geraniums, I usually keep the grandmothers and great-grandmothers and pull out all the spindly, feeble stems, leaving maybe seven or eight healthy ones to continue growing on. After that, plant them in a healthy bed of fresh, multipurpose potting compost that is rich in nutrients.
Geranium cuttings with the best appearance should be divided into 4in sections; reject any that don’t have many shoots or nodes. Remove almost all of the stem’s leaves from each portion, leaving only the top pair. Additionally, remove any tips that appear to have the potential to grow into flowering shoots.
Put the geranium cuttings into a grittier compost mixture until they are roughly one-fourth of their depth. These square bulb containers are my favorite for cuttings. They are well-spaced and equally separated, and they appear good in the positions they take as they sit and stand. If you have a heated base, place them on it. If not, store them somewhere bright, cold, and moist at all times.
Within a month, geranium cuttings should have taken root and can be potted on. Three plants together in a huge pot will swiftly develop to the size of one bumper-sized plant that is healthy, floriferous, and attractive. This will give you a great tumble of flowers and leaves.
overwintering
In the winter, the majority of geranium kinds will die back, so if you’re a neat gardener, you may shear the dead leaves off and toss them to the compost pile. They don’t require any winter protection because they are bone tough.
Can geranium cuttings be placed in water to root?
Geraniums can grow roots in water, yes. Approximately 6-inch-long cuttings should only have the top leaves left on them. Place the cuttings in a water-filled container in a well-lit area away from the sun. To prevent leaves from rotting in the water, make sure to remove all foliage from any cuttings that may fall below the water’s surface. Hopefully, the cuttings will ultimately produce roots so they may be replanted.
By putting the cuttings in moist vermiculite or perlite, you might have more success. These soilless products encourage good moisture retention and aeration. To promote root formation, dip the bottom end of the stems into rooting hormone. A slow-release granular fertilizer made for annual flowers works nicely on geraniums.
Which is preferable, geranium cuttings rooted in soil or water?
Geranium plant cuttings take root quite well and don’t require any herbicide or fungicide, yet complete success is unlikely. Simply place your cutting in a container filled with warm, damp potting soil. Place the pot in a bright area away from direct sunlight and give it a good watering.
Geranium plant cuttings are prone to decaying, therefore don’t cover the pot. When the soil feels dry, water the pot. Your geranium plant cuttings should have roots in only a week or two.
Allow your cuttings to remain in the open air for three days before planting them in the ground if you intend to do so. By doing this, the clipped tip will begin to develop a callus that will help protect it from rot and fungus in the non-sterile garden soil.
How long do geranium cuttings take to root?
- Make a hole in the container mixture with your finger or a dibber, then insert the geranium stem.
- Take care not to push the powdered rooting hormone aside.
- Around the stem, loosely fill the hole with the container mix.
- Ensure that the stem is buried deeply enough to cover any bare leaf nodes (where you removed leaves).
- You can either fill the drip tray and drain it after 30 minutes, or you can water the pots.
Cover (Optional)
- You shouldn’t need to cover the cutting if your growing area has good humidity (above 50%) and there was no danger of it drying out.
- Alternately, in a dryer atmosphere, provided there is still airflow, you can loosely lay a large, clear bag over top or a dome.
Make sure the cover is not accumulating too much dampness, mold, or fungus on the soil by checking every day.
Location
- Keep in a warm area, either inside close to a window or outdoors in partial shade (during the summer). until roots have developed, avoid direct sunlight (it usually takes a few weeks).
- Keep the container mix damp but not drenched.
Growth
- You should see the roots sprouting in 6 to 8 weeks. As little as four weeks may pass.
- Geraniums have long roots, so you might see some of them near the pot’s drainage holes.
- You may also see if roots are holding the stem in place by lightly pushing on it.
Hardy geraniums should you deadhead them?
Once established, hardy geraniums require minimal maintenance. After blooming, the plants might become a little scraggly, and deadheading is challenging due of the abundance of thin stems. Restoring the plants to their basal growth will enhance their appearance and promote reblooming. Within a few weeks, the plants recover.
What hardy geranium varieties are fertile?
I have been removing ‘nuisance’ plants that have sprouted as seedlings for the past few weeks. I have filled up the green bin with pincushion scabious (the wilding blue Knautia arvensis and the maroon-red K.macedonica), mallows galore (mostly the blush-white Malva moschata), and countless meadow cranesbills because I was too afraid to add them to the compost heap for fear they would persist in years to come (Geranium pratense). I’m the only one to blame for these bandits smothering my prized plants, many of which are now lost. Because it was so miserable outside last summer, I stayed indoors and didn’t go out to deadhead. I now have a forest of unwanted seedlings as a result. It has helped me appreciate my sterile plants—those unable to produce seed—more. They flower for much longer since they are sterile. It can be caused by having inadequate reproductive organs, being too petal-stuffed to allow pollinators to enter, or even incompatible pollen. The extra petals on the doubles typically take the place of stamens, etc. Plant breeders highly value these complete flowers, but pollinators and insects do not value them as much. A bee cannot survive on many double roses.
Having some long-lasting doubles, such Rose “Buff Beauty,” and some singles or semi-doubles, like “Bonica,” is typically the ideal compromise.
Many hardy hybrid geraniums, which are likely hybrids of closely related species, are sterile. The best sterile geraniums take up a lot of space, and these hybrids frequently have extra vigor. The mid-blue “Rozanne,” the black-eyed magenta “Patricia,” and the deeper blue “Orion” are the top three. ‘Rozanne’ was discovered growing in the yard of Rozanne and Donald Waterer in Kilve, Somerset, some 24 years ago. This plant was chosen as the Plant of the Century at the Chelsea Flower Show this year (1989).
It has a spreading habit and a flower that is quite similar to Geranium wallichianum ‘Buxton’s Blue’ in appearance. The flowers, however, are bigger and occur in the summer rather than the fall. Of the three, “Rozanne,” which also possesses G. himalayense as a parent, is perhaps the most desirable. It took Blooms of Bressingham, who introduced it at the Chelsea Flower Show in 2000, to micropropagate it because, like many sterile plants, it cannot be propagated conventionally. ‘Jolly Bee,’ another identical plant created by Macro van Noort, was also available for purchase. It was taken off the market in July 2010 after a lengthy, seven-year legal battle determined it to be the same plant. The moniker “Jolly Bee” was appropriate since despite Rozanne’s sterility, bees still come to visit. Johnson’s Blue and the deeper blue ‘Orion’, a ‘Brookside’ seedling discovered by Dutch nurseryman Brian Kabbes in 1990. It gained notoriety during the 2002–2006 RHS Wisley trial of hardy geraniums. “Orion” starts blooming in May, takes a break in July (when it needs to be shorn down), and then continues until the end of the season. It hates drought and is tall and voluminous. In 2011, when my garden was eerily dry, I lost a number of plants.
My third eye-catcher is the black-eyed magenta “Patricia,” a purposeful hybridization of G. endressii with G. psilostemon by Orkney plant breeder Alan Bremner. This one is not for the weak of heart; it is bold and bright, and I admire it for its success.
The majority of long-flowering plants are sterile, and they include the lacy orange Geum ‘Prinses Juliana’, the exquisite Jacob’s ladder Polemonium ‘Lambrook Mauve’, and the early-flowering wallflower Erysimum ‘Bowles’ Mauve. The latter will bloom for 14 weeks, although a few years ago I planted Tim Crowther of Walberton’s Nursery’s superior, paler ‘Totally Tangerine. This has survived frigid springs, arduous winters, and damp summers to produce long wands of blossom in the early summer that last for several months.

Can hardy geraniums be grown in containers?
Can hardy geraniums be grown in containers? This query has recently come up from new gardeners.
Without a doubt, the response is YES! You can definitely plant your favorite hardy geraniums—say let’s Geranium Rozanne—in your favorite garden containers. Rozanne enjoys dripping from window boxes and hanging plants. She also enjoys leaning over the edge of large planters. As it turns out, container gardening is a great way to highlight Rozanne’s best qualities. Here are some justifications on why this may be the best option for you.
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.
