They are frequently seen on rooftops, in sedum “carpet placements,” and in rock gardens. To grow new plants, all of these many types are simply propagated. My mother frequently starts sedum plants in water, then transplants them to a container with potting soil once they have taken root.
Can sedum be grown in water?
Showy sedum can be used in containers, as ground cover, in rock gardens, borders, and as gifts. Some examples include Autumn Joy, Autumn Fire Stonecrop, “Postman’s Pride,” “Brilliant,” which has bright pink petals, “Stardust,” which has silvery-pink flowers, and “Brilliant,” which has variegated foliage on “Frosty Morn.” At the garden center, I made my first showy sedum purchase. Debating the purchase price, which was reportedly between $10 and $25 per item! I brought one home and quickly learned how simple it is to spread. Consider taking cuttings from your neighbors, bartering for other plants, and employing sedums in various guerilla gardening endeavors. Since Showy Sedums are succulents, the guidelines from my earlier piece on propagating succulents still hold true. Showy sedums are 18–24 inches tall and bloom from midsummer to October in my cold climate garden. They are relatively pest-resistant and require minimal upkeep. The aged stems and foliage provide superb winter appeal. The colorful sedums wither to the ground in the winter and then reappear in the spring from their tuberous roots.
I’ve even taught young children how to grow sedum. You are capable of doing it. There are three effective methods of propagation:
- Immersion
- Managed Plant Growth
- Direct Garden Positioning
- Division
You must take a cutting from a healthy sedum plant for procedures 1-3. I often cut the subject sedum back to the ground using a single stem. Then, if needed, I can cut this into three or four smaller pieces for propagation. Although some may advise taking only the soft tops of the sedum for propagation, there is no need to worry about using only the tip piece. By the way, several of these methods also work fantastically on herbs.
1. TECHNIQUE OF IMMERSION:
This method calls for a somewhat longer cutting. I often take a 6-inch-long chunk. Leaves on the lower part of the cutting should be removed since they could rot because they would be submerged. Place the pieces of Autumn Joy that you have cut up for propagation in a cup or glass that has water in it. Make sure that the water only contains the sedum stem ( no leaves.) After that, put the glass in a room that’s warm and well-lit.
Change the water every few days and make sure it doesn’t entirely dry up. Your cutting will start to root and develop new growth in a week. The images below can be seen. The sedums can be kept in water for a while, but eventually you should transplant them outside. Even in August through October, they can bury themselves. I make an effort to group at least three of these tiny sprouts. Once you’ve done so, make sure to keep your plants well-watered until their roots have taken root in the garden soil. For 10–12 days, I attempt to water every other day.
2. CONTROLLED POT GROWTH (Cuttings): I usually recall that I want to propagate more sedum in the late summer. I prepare the stems by slicing them into rather long portions of around 6 inches and removing the lower 3 inches of leaves. I next fill small pots with standard potting soil that contains around 10% perlite. Put the pots with the sedum cuttings inside.
Make sure there are no leaves embedded in the ground. Water the sedums on a regular basis (they have dried out sometimes without ill-effect.) New shoots will grow from the plant’s base when the initial stem cutting withers away (note the tiny shoots to the right?). winterizing the sedum plant in a pot indoors (in your in a cold climate). The fragile shoots will wither and not grow back if you plant them outside in the late autumn. The sedum shoots occasionally have a chance to completely die back when kept indoors. Not to worry, they sprout back in the spring. Winter watering should only be done to prevent the soil from becoming brittle because too much water would rot the young plants’ roots. You should be able to plant cuttings directly in the garden once the shoots emerge if you start them in pots early enough in the summer. If not, simply wait until spring to plant them outside after they sprout in the containers.
3. PLACEMENT DIRECT INTO GARDEN (Cuttings)
This method is as simple as it seems. Early summer or late spring are the ideal times to perform it. As previously mentioned in the chopping part above, prepare the stems. To prepare a spot in the garden, add some peat moss and possibly some potting soil to the soil to lighten it. After that, place each stem directly into the garden where you want the new plant to emerge. I prefer to leave 3 nodes below ground and 5 to 6 inches of the stem above ground that is still healthy. It’s fall, so there isn’t much color in the image on the left below; the stick-shaped plant is a sedum. If there hasn’t been any rain, water. At the ground level, the roots will start to develop and new growth will start. The original stem might or might not persist. You will eventually have a lovely clump of fresh sedum after a few years (see picture on right below)
The stem may root if you use this approach late in the growing season, but new growth won’t appear until spring. If there is any resistance when you lightly pull on the sedum stem you planted, there are roots there.
4. DIVIDE: As with many perennials, the final option is to break up established clumps into smaller groupings and replant them.
Sedums can be found in Africa, Asia, South America, Europe, and North America (including Greenland). It is native to China and Korea for showy sedums. The well-known hybrid “Autumn Joy” (S. “Herbstfreude”) has broad, alternating leaves and blooms toward the end of the growing season. The prestigious British Royal Horticultural Society bestowed an Award of Garden Merit on the sedum “Autumn Joy.” I suppose that’s why we all want it! Given how simple it is to spread them, I hope you tell your friends about your happiness!
Email me if you are in the Chicago area and would want some cuttings to start your own sedums.

Can sedum be grown from a cutting?
I’d want to have more sedums than the few that are currently flourishing down my driveway. They have stunning late-summer blooms. I was advised by someone that I could cut them. Ist das so? If so, how can I do it and when?
One of the simplest plants to grow from vegetative cuttings is sedums. Cuttings make it simple to grow taller, fall-blooming types like “Autumn Joy” and “Brilliant,” as well as creeping sedums (also known as stonecrops). In actuality, whenever the stems of creeping sedums make touch with the soil, they frequently root all the way down their length.
You can grow your sedum plants in one of two ways. One is for cuttings of stems, and the other is for cuttings of leaves. Regardless of the method you use, this activity is best carried out in the early spring, when the plant has grown to a height of approximately 4 inches.
A fairly easy method of propagating sedums is by starting new plants from stem cuttings. By taking a stem cutting, you cut off a section of the mother plant’s stem and force it to develop a brand-new root system.
With a clean pair of scissors, a few tiny plastic pots, a bag of sterile potting soil, a bottle of rooting hormone, and a variety of clear plastic baggies and twist ties, you can start taking stem cuttings. Wet potting mix should be added to each pot, and it should be lightly compacted. With the scissors, separate a number of 2-inch-long stem segments from the mother plant. There should be two growth nodes in each segment of the stem (the place where the leaves meet the stem). The top two or three leaves should be kept since they will offer the energy needed to produce new roots. Remove the lower leaves.
Each freshly cut stem should be dipped in rooting hormone for the bottom inch before being firmly placed into a pot of potting soil up to the bottom of the last leaf.
One cutting should be placed in each pot, which should then be watered and let to drain. Each individual potted cutting should be placed in a clear plastic baggie with the top opened. The baggie should be sealed with a twist tie. The cutting won’t dry out because of the high humidity this maintains till it develops its own roots in a few weeks. Place the covered pots in a shaded area of the garden or on a window sill with natural light.
Always let the pots drain before re-entering the bag after removing the bags and watering them as needed. You can take the bags off after approximately a month and keep watering as needed. The plants will be prepared for planting in the garden two weeks later.
Additionally, you can grow new sedums via cuttings from leaves. This process requires a little bit more time, but each leaf cutting can produce dozens of little plants. By using a single leaf or a piece of a leaf, leaf cuttings can produce new plants. This mother leaf rots away rather of becoming a part of the young plant(s).
Using a clean, sharp knife, cut off a single leaf from a sedum plant to create a leaf cutting. Insert the bottom half of the leaf into a pot filled with sterile potting mix after dipping the base of the leaf in rooting hormone. Keep the cutting well-watered and covered with a plastic bag. Where the chopped leaf touches the potting mixture, a new plantlet will grow.
You can alternatively take a single leaf, nick the outer edge several times with a sharp knife, sprinkle rooting hormone in the nicks, and then pin the leaf flat onto the potting soil. Small plantlets will emerge from each of the nicked areas in a matter of weeks. You’ll have lots of tiny mini sedum plants for your garden after the mother leaf rots away.

Which is preferable, soil or water for germination?
Even if you already know how to root a plant in water, David Clark, a professional gardener, has some excellent advice that will help you make the procedure more effective.
He offers advice on two simple plant-starting techniques that you might not have known about.
Two practical workshops on plant propagation were recently presented by Clark at the Buffalo and Erie County Botanical Gardens.
He provided a plethora of knowledge, including these five excellent suggestions:
1. Build a miniature greenhouse. How frequently have you purchased comforters or bedding that was packaged in a plastic zipper bag? I frequently do so, and I usually consider, “This bag ought to be useful for something.
According to Clark, these bags make excellent miniature greenhouses for newly transplanted or rooted plants. Simply place the plant inside the bag and partially zip it up. This will assist in retaining moisture. In addition, a small aperture permits airflow to stop the development of mold.
“Because the plant needs to be confined, unless you have a greenhouse, Clark explained, I almost always root with a bag.
The bedding bags, as shown in the picture at the top of the article, can hold either a sizable plant or a number of smaller plants.
2. Use powders for rooting. By soaking a plant cutting in water, you can multiply plants in one of the easiest ways possible. Trim the stem horizontally above a node (see photo above). Soft, fleshy plants like the Wandering Jew, ivy, arrowhead plant, and spider plant respond nicely to this technique.
Using rooting products will boost your chances of success, according to Clark. There are numerous commercial goods available. These products contain a growth hormone to hasten the emergence of roots and destroy bacteria and fungi to stop the stem from decaying.
Dip your stem into the powder after dispensing a tiny bit of it. (Avoid inserting the stem into the product container directly.) Give the stem a minute to settle. The powder will be absorbed by the plant. Put the cutting’s tip in water; the water won’t completely wash the powder away.
He added that you can also utilize common home items to speed up roots. Cinnamon can be used to eliminate fungus and bacteria on plant stems. Make a rooting solution by dissolving one aspirin in water to encourage the formation of roots.
3. Give your new plant enough time to adjust to soil after being in water. According to Clark, if you root your cutting in water, it will grow roots that are best adapted to obtain its nutrients from water as opposed to soil. The plant could become stressed if it is transferred from water to soil right away.
As an alternative, mix a little dirt into the water you’re using to root your cutting. Do this gradually over the course of four or five weeks to allow your plant adjust to its new growing environment.
4. Learn about leaf section division. You may grow new plants from the leaves of succulents like the sansevieria pictured above. It’s not even necessary to utilize the full leaf; only a portion will do!
When you cut the leaf, Clark advised, be sure to mark which portion is the top and which is the bottom. As shown in the leftmost photo below, place the bottom portion of the leaf segment into a tray of moist perlite. (Fun fact: Perlite is a byproduct of volcanoes.)
5. Encourage plant runners as a means of division.
View the image of the Wandering Jew that is located close to the beginning of this article. Burying the stem horizontally is another approach to multiply such a plant. These nodes will produce new plants.
