To prepare each cutting for potting, Monty Don recommends removing all of the lower leaves and side shoots, leaving only 1 inch (2.5 cm) or less of foliage.
He then suggests trimming the stem to size once again with a sharp knife or secateurs and burying it in a container. Monty suggests compost that is very grippy or sandy. Our professional guide contains advice on composting at home.
Cuttings should be placed around a pot’s edge, and Monty usually places four or more in a single container.
What time of year should I trim 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.
How are geraniums 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.
In how long do geranium cuttings take to root in water?
Water should be added to the jar to cover the main stem but not the leaves.
Place in a space that maintains a temperature between 65 and 75 degrees Fahrenheit on a sunny windowsill.
To keep the water fresh, change it every day. At the base of the stem, roots should start to form after around four weeks.
How long does it take for geranium cuttings 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.
What time of day is ideal for taking cuttings?
Learn how to take cuttings of your favorite garden plants on day six of our 30-day gardening challenge so you can grow additional plants for nothing.
Time it right
Early spring is typically the optimum time to take cuttings from a parent plant, such as a salvia. It’s a quick and enjoyable way to enhance your plant supply.
When taking cuttings, it is usually ideal to do it first thing in the morning, while the parent plant is still turgid, or full of water. The best possibility of rooting is ensured by doing this.
Cutting instructions
Cut a few wholesome stems to a length of approximately 10 cm using a clean pair of secateurs or a sharp knife.
Reduce the stems to a node’s width (or leaf joint). The majority of the latent root buds are concentrated here.
Position the pot
Put the pot in a heated propagator with a hood or wrap it in a clear plastic bag to protect it from the elements. Place in a well-lit area away from the sun.
This is a fantastic strategy to proliferate early in the season if you want to take cuttings. Watch our step-by-step video tutorial to learn how to make softwood or soft tip cuttings later in the year, in the summer.

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.
How does using honey as a root hormone work?
Once your cuttings are prepared, dip each one into the honey and then poke a hole with your finger into the potting soil for each one. You can anticipate roots forming in 714 days if you keep the potting medium moist. You can dip succulents in honey and set them on top of the potting soil.
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.
Is it possible to grow geraniums from a single 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.
Do geranium cuttings float 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.
Should geranium cuttings be fertilized?
Three to four weeks after rooting, the geranium cuttings are prepared to be planted in 4-inch pots once new roots have formed. Since the new plants will develop in these pots for the remainder of the winter, fill them with good potting soil. Geranium cuttings should be planted in big containers for the patio or in the garden in the spring.
When the soil’s surface is dry, water. The cuttings receive all the nutrients they require from a weekly application of liquid 20-20-20 fertilizer. Just be sure to wait till one week has passed since transplanting the cuttings before fertilizing. Fertilizing before the first week of rooted will impede root growth.
Can hardy geraniums be cut for cuttings?
You may effectively cultivate geranium species including G. pratense, G. sanguineum, G. versicolor, G. maderense, and G. argentum from seed. In general, cultivars do not, and they typically rely on vegetative techniques like those described below.
But if you enjoy surprises, spreading seeds from cultivars can be entertaining. For instance, the typically white and blue flecked flowers of the cultivar G. pratense Striatum (Splish Splash) can be all blue, all white, or a mixture much like the variety!
The months of autumn can be a good time to sow after gathering seed and keeping it dry throughout the spring and summer (paper envelopes or bags are ideal—never plastic). Another excellent time to plant seeds is in March or April of the following year.
Spread a thin (0.5 cm) layer of fine, sand-based compost mix over the gritty compost before sowing in pots or trays. Water from below by placing yourself in a tray of water and placing it in a bright area away from the sun. Don’t give up; germination can take anywhere between two and four weeks, though it frequently takes much longer.
Small pots (7 to 9 cm are good) should be filled with gritty compost. Using a dibber or pencil, make 5 to 7 holes so that you may insert the pieces afterwards (top uppermost). Cover with a thin layer of horticultural grit after inserting deeply enough so that the top of each root is level with the compost. Before storing the pots in a cold frame, greenhouse, or another protected area, water them and mark them. They’ll survive the winter cold just well, but some cover will shield them from the worst weather, like a downpour.
The cuttings are ready to be divided up and put into separate pots after roots start to show through the drainage holes.
The root cuttings may alternatively be laid out horizontally on top of the compost’s surface.
Lay the pieces horizontally on top of the compost in pots or trays filled with grit. Press them firmly into the compost and cover with grit to make sure they make good contact.
Many alpine species typically make suitable stem cutting propagation choices. works well with Geranium cinereum, Geranium farrei, and Geranium “Bertie Crg.”
Anytime during the growing season is a good time to take stem cuttings. Early in the morning is the finest time of day to take stem cuttings. Cut a few good stems off using a sharp knife, then cut each one into 3-6 cm pieces slightly below a node. Leave only 2 or 3 leaves on each stem piece, and remove any blooms or seed pods.
Insert the cuttings into pots of grittier compost using a pencil or dibber, then place them in a greenhouse or cold frame away from direct sunshine.
