Any time during the growing season, when a plant is experiencing a flush of new growth and just before it begins to form buds, is the ideal moment to take a cutting.
Taking cuttings in the fall before the plants go dormant will ensure that you have new, fresh plants to plant out in the spring if you are growing garden geraniums as annuals.
This is how you do it:
Select a stem with strong leaves. Aim to steer clear of the weakest, most recent growth, the oldest, woodiest stems, and any with discolored or damaged foliage.
Cut four to six inches down from the stem tip, right below a leaf node.
To leave three to four inches of bare stem, snip off the lower foliage and leave two or three leaves at the top. Remove any flower or leaf buds that may divert energy from the production of roots.
Geranium cuttings can be rooted in water.
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.
How may a geranium be started from cuttings?
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 drier environment, you can loosely sit a large, clear bag over top or a dome, so long as there is still air circulation.
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.
How do I gather geranium seeds?
Geraniums feature a spring-loaded seed distribution system, which means that as soon as the seed is ready, it is pinged away from the plant for up to three meters, making seed collection from these plants challenging.
The fact that many current cultivars are sterile and hence don’t generate any seed further complicates matters. Typically, garden centers with non-Latin marketing names will sell these.
So, if you wish to collect seeds from a geranium, you must first carefully examine the “seed heads” and check to see if there are five hard, bulging pods at the base of the primary flower spike. If so, the following visual cues indicate the ideal time to collect the seed:
The far left pair should be left alone until both the central spike and the seed casings at its base start to darken because they are still too green. Black spike and dark seed pods, which are in the middle, are ideal. The seed has been released, the two on the right are too late, and you can still make out the ruins of one of the springs.
These are geranium pratense seeds, however viable geranium plants of any variety will yield the same results.
I gather them by delicately wrapping my palm around a pair of ripe seedheads (they usually grow in pairs) and cutting with scissors. By pulling, there is a chance that the plant will scatter its seeds. After that, put the seedheads in a paper bag and let them ping for about a week on their own. If seeds are placed right away, they may sprout rapidly. If not, it may take a cold snap to induce them to sprout, so place a seed tray somewhere that will get some frost without getting too wet.
Are geraniums contagious?
The one we like best among them is Rozanne. She is a lot of fun to be around because she can adjust to many different situations. Place many Rozannes in the ground, separating them by a distance of between 30 and 106 cm. She tends to grow out and create excellent ground cover when planted in the ground. When planting Rozanne by herself in a container, choose one that is at least 40 cm in diameter.
Zonal geraniums (aka Pelargoniums)
These have patterns or zones on their leaves which give them their name. They produce large, colorful flower heads on top of their dark, zonal leaves. Planting zonal geraniums where they will receive six to eight hours of sun each day requires spacing them at least 30 cm apart. Zonal geraniums do well in cooler climates but cannot tolerate colder than freezing temperatures.
Ivygeraniums
These are perfect for containers, troughs, and window boxes because of their ivy-like leaves and long, trailing branches. They require up to 91 cm of space when planted in the ground to accommodate their long branches. Below 27C, ivy geraniums thrive in full light (80F). In warmer temperatures, plant them in partial shade.
Scented geraniums
These are named for the scents of mint, citrus, apple, chocolate and rose released from their leaves when gently squeezed. They feature thick, hairy leaves and little flowers. This fragrant plant prefers all-day direct sunlight and may thrive in all but the coldest climates. These aromatic indoor plants grow best in light areas and prefer to be placed in containers.
Martha Washington or Regal geraniums
These have lush, velvety flowers and brilliant green leaves. For these geraniums to blossom, lower temperatures are required. Plant these geraniums at least 30 cm apart because regals have a tendency to spread out and take up a lot of space.
What time of year do you take geranium cuttings?
Taking Cuttings of Geraniums Since geraniums don’t go dormant in the winter, cuttings can be taken at any point throughout the season, but April is the ideal month. For the best outcomes, success depends on light, warmth, and hydration; warmth and more daylight result in stronger plants. 1.
Can a geranium be grown from a leaf?
Yes, you can grow aromatic geraniums even from a leaf cutting. If you don’t have much stuff to work with, this may be useful.
Although leaf cuttings can also be planted in potting soil, stem cuttings are preferred since they are more dependable and take root much faster.
You can verify this by planting the lowest leaves from a stem cutting in their own potting soil instead of discarding them.
Cutting off a small portion of the stem while removing a leaf from the stem is essential for effectively propagating a geranium from it.
To prevent it from losing too much moisture, place the leaf between the compost and the side of the pot and cut back roughly half of the leaf surface.
Use a plastic cover in this situation, but make sure it doesn’t touch the leaf as it will greatly aid in the rooting process.
How are geraniums divided?
In order to give the plant enough time to establish its roots before a frost, divide the geraniums in the early spring to early summer. Shake the earth off the plant’s roots by digging it up. Make divisions with a trowel or knife, being careful to include a root section and leaves in each division.
Hardy Geraniums vs. Pelargoniums
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.

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.
