The ideal time to divide ‘Autumn Joy’ and other upright, clump-forming sedum cultivars is early spring (Hylotelephium). Plants should be dug up in the early spring right as new growth starts to develop. Use a sharp knife to slice off each clump. The root system and multiple shoots should both be present in each division. Right away replant the divisions. Sedums thrive in full light and well-drained soil.
When should sedum be divided?
To propagate more of these well-liked plants, whether you have little spreading rosettes or tall Autumn Joy stonecrop, you should be able to divide sedum. Sedums flourish in hot, arid regions of the landscape and brighten up places that are difficult to cultivate with color and whimsical form. Sedum separation is a simple task that will immediately boost the availability of plants that are simple to grow. New divisions take little extra work to establish themselves.
In late fall to early spring, perennial plants are typically divided. When to divide sedum will determine how quickly they recover and take root. Before new growth appears in the early spring, it might be challenging to pinpoint the location of the plant because many sedum die back in colder climates. The optimal time to divide the plants is at that point.
Plant division can improve plant health and increase blooming. Every three to four years, divide your sedum. Additionally, some growers advise splitting the plant into two while it is still developing after blooming. Although recovery will take longer, these resilient little succulents should do okay.
Size & Growth
Autumn Sedum spectabile Joy grows at a moderate rate and keeps expanding until the plant is 24 inches tall.
It is described as hardy to grow in USDA hardiness zones 3 to 9, has a rounded look, with a spread of roughly 18 to 24.
Flowering and Fragrance
Autumn Joy develops flower heads with stunning ornamental rich, dark pink flowers that will either be pink, white, or red in hue during the bloom period from late summer to late fall.
These flowers emerge as a light green, develop pinker petals, and gradually fade to a coppery brown color before the arrival of winter. There is no scent to the blossoms.
Light & Temperature
Since it is not frost-resistant, it is not likely to endure low temperatures of 30 degrees Fahrenheit. When spring returns, though, it will grow again.
Watering and Feeding
Autumn Joy uses a small amount of water. Due to its capacity to store water in its thick leaves, once established, it can withstand drought conditions.
When the soil starts to dry up, the plant will thrive with routine irrigation. Avoid overwatering Autumn Joy plants.
Avoid using high-nitrogen kinds when fertilizing because the nitrogen encourages flimsy growth in plants.
Soil & Transplanting
A healthy Sedum needs soil that drains well. In heavy, soggy soil, it cannot live.
Rich soil should also be avoided because it makes plants develop more slowly and with drooping stems.
This will allow the roots some time to establish themselves before the summer’s intense heat hits.
When is the best time of year to transplant sedum?
In cooler climates, sedum should be transplanted throughout the early spring after the last frost of the season because they wither away in the winter. Because of this, it is challenging to pinpoint the plant’s location before springtime new growth appears.
It may be the soil quality if you’ve discovered that your sedum is toppling over. Spindly stems from plants growing in low light may also be to blame for the drooping. To save your sedum if this occurs, transfer them into a spot with full sunlight and better soil.
To ensure that the sedum can be transferred rapidly before the roots dry out, first prepare the planting place. Select a location with ample sunlight and sufficient drainage, staying away from wet places. With a garden fork, loosen 10 to 12 inches of soil in the new area. Add 2 to 3 inches of compost after that.
Do I need to trim my autumn Joy sedum?
A solid option for the late summer and fall garden, Sedum ‘Autumn Joy’ provides foliage interest earlier in the season and then puts on a color display of bronze-red flowers in the fall.
Sedum ‘Autumn Joy’ (Sedum spectabile ‘Autumn Joy’) can spark vibrant fall color in your landscape beds. This paddle-leafed perennial, also known as Hylotelephium ‘Herbstfreude’ (herbstfreude is German for “October delight”), is hard to match for adding seasonal interest. Learn some growing advice for the sedum “Autumn Joy.”
‘Autumn Joy’ sedum stores water in its fleshy, swollen leaves, just like other sedums do. This sedum plant is a variety of succulent related to jade plant and hen-and-chicks (Sempervivum tectorum) (Crassula ovata). All of these plants have water-saving leaves that thrive in arid, low-fertility soil conditions. These water-smart plants may actually be doomed by a garden soil that has been enhanced with compost.
Autumn Joy sedum grows lushly in rich, nutritious soil, producing weak, floppy stems as a result. With this long-season performer, clumps that start the growth season firm and upright but end with bowing and flailing stems are among the frequent experiences gardeners enjoy. Stem flop can be avoided by maintaining light, lean soil, which is one trick. If you’re planting plants into rich garden loam, think about adding a shovel of sand to the planting holes.
In addition, early in the growing season, use hoop or grow-through type poles around plant clumps to keep stems of “Autumn Joy” sedum standing upright. If plants are not in full sun, stems also flop. All sedum plants, including the sedum “Autumn Joy,” adore the sun.
Numerous gardeners engage in spring and summer pruning, which involves cutting back the stems of “Autumn Joy” to encourage plants to grow to a smaller overall height. Additionally, pruning results in shorter stems with more branches. To prune sedum, trim plants down by half in late spring or early summer (June in most places) (June in most places). Pruning makes “Autumn Joy” sedum flower later, prolonging the fall flower display.
The sedum “Autumn Joy” develops flower buds on its stems in the summer. Long-lasting chartreuse buds give the summer garden some interest. Pink blooms with a six-week garden lifespan are shown as the green buds in the late summer open. The blossoms eventually develop a bronze shade that resembles almost chestnut brown and stands firmly in the snow in the winter. For aesthetic purposes, many gardeners leave flowers in their gardens all winter long.
All different sorts of pollinators are drawn to the attractive flowers. As a late-season nectar source, the sedum “Autumn Joy” is a wonderful addition to a wildlife or butterfly garden. Bees, wasps, and other pollinating insects can land on its blossoms, which offer broad landing surfaces.
Between Zones 3 and 8, “Autumn Joy” sedum thrives. There are numerous additional variations of this autumnal staple. The traditional “Autumn Joy” sedum opens green leaves above light pink blooms. Similar blossoms are found on stems of the “Autumn Charm” sedum (Sedum telephium ‘Autumn Charm’), which has leaves with a white border and green variegation. A better version of “Autumn Joy” is “Autumn Fire” (Sedum spectabile “Autumn Fire”). ‘Autumn Joy’ is gradually being phased out of the market. Autumn Fire has a longer flowering window, bigger flower heads, and stronger stems than Autumn Joy.
How far apart should autumn Joy sedum plants be spaced?
Sedums can be grown from seeds with ease. Your seeds can be started inside four to six weeks forward to your last frost date or directly sown in your sunny garden in the early spring. The soil’s surface should be where the seeds are planted. Avoid covering them. They require sunlight to sprout. After germination, thin your seedlings so that each plant is spaced 6 to 12 inches apart. Larger varieties need to be separated by 24 inches. After all threat of frost has passed, you can transplant your indoor-started seeds onto your garden.
How can sedum be prevented from flopping?
A man’s fist-sized or even larger bloom cluster is possible on some sedum plants. The large flower can typically be supported by the top-heavy sedum, but occasionally the flower will droop to the ground or the stalk may even shatter.
A soil that is too rich will result in weak stems. Sedum plants can tolerate difficult growth circumstances and can even flourish in sand or other abrasive soil. The stems will bend in rich, wet soil, and you’ll see your sedums toppling over. Before planting the succulents, add some sand to the site soil to avoid this.
In low light conditions, Sedums may also have spindly stems as they reach for the sun. Make sure that these succulents receive enough sun.
Why does the middle of my sedum crack open?
For tall sedum cultivars that aren’t regularly pruned, floppiness is common; eventually, the plant gets top heavy and collapses under the weight of the blossoms. Floppiness and caving in at the core of the plant are also frequently caused by inadequate sunshine and excessive soil richness. A warm-weather succulent plant called sedum does well in average or poor soil and abundant sunlight. Some sedum species are hardy enough to flourish in arid, rocky soil.
- Even though sedums are resilient plants that require little care to flourish in even adverse conditions, they frequently get floppy and collapse in the middle.
- Some sedum species are hardy enough to flourish in arid, rocky soil.
Do sedum’s roots go deep?
Sedums of the Crassulaceae family are said to have the ability to shield persons and property against lightning strikes. I therefore took solace in the notion that since I was seated near a patch of sedums while I was on our porch during a thunder storm, I was probably not going to be struck by lightning.
By the way, I am aware that there is a much lower likelihood of being struck by lightning than taking home the Mega-Millions prize. However, before the storm became too severe, I withdrew inside since I didn’t want to take a chance. But when I was standing outside, I thought of a few additional justifications for why I had sedums planted next to our porch. Why?
Shallow-rooted succulent annuals and perennials called sedums are endemic to temperate regions. The perennial varieties, sometimes known as “stone crops,” are perfect specimens for extremely shallow soil. In fact, as long as the site has good drainage, sedums can grow and thrive in soil that is less than 1/2-inch deep.
Interestingly, the Latin term “sedo,” from which the English word “sedum” is derived, means “to sit,” and thus refers to sedum’s apparent capacity to thrive on soilless stones. Sedums do, however, thrive in both acidic and alkaline soil, as well as in both full sun and partial shade.
Sedums are also simple to grow from seed because their small leaves—which can be found in a number of appealing tones of green, grey, blue, bronze, or red—produce roots wherever they come into contact with the ground, even if they are not connected to the mother plant’s ground-hugging stems.
Additionally beautiful are the star-shaped blooms, which can be pink, red, yellow, or white depending on the species of sedum.
Sedums are excellent plants for the fronts of borders, rock gardens, ground covers, fissures, and crevices because they rarely grow taller than 3 inches.
The threat of a late-spring frost is no longer present, and the soil is now warm enough for seeds and transplants of frost-sensitive plants to grow successfully outside.
Planting frost-sensitive species, such as warm-season vegetables and annual floral plants, never happens until late May or early June. The harvest is therefore larger than when I plant early and subject seedlings and transplants to the pressures brought on by cold soil and air temperatures, even though I may lose opportunities to harvest flowers and veggies early.
Sedum spreads quickly, right?
Sedums can survive in less-than-ideal environments, therefore the author covers a stone wall with a variety of them (identified in chart below).
A creeping sedum may be the ideal plant for you if you want something attractive that can survive with almost complete neglect. Sedums show off where many other plants would be afraid to tread. For instance, they settle in the crevices of a garden wall or pathway, on roofs or the tops of birdhouses with slightly sloping roofs, or even under huge trees where their gigantic roots control the majority of the soil’s moisture. Additionally, they function well in borders, containers, and rock gardens.
Many gardeners have started looking more closely at plants in the genus Sedum as seasonal and protracted droughts become more frequent across the United States. The ground-hugging relatives of Sedum ‘Autumn Joy,’ which is well-known for its late russet blooms, are also gaining popularity.
In my yard, creeping sedums, often called stonecrops, provide endless fascination. Over the course of my many years as a gardener, they rank among the most adaptable, drought-tolerant, and simple-to-grow perennials I’ve ever grown. Sedums really require less work from a gardener as their area grows. These slow-growing plants, which are renowned for their propensity to spread swiftly, prevent weeds from taking root. Since they eventually just fade away, it is not required to deadhead the spent blooms, but it is simple to get rid of old blossoms using a string trimmer. They rarely contract illnesses or pests as long as they aren’t overwatered.
Even the poorest soil may support sedums, and small amounts of soil are really their preferred medium. However, the key to cultivating them is proper drainage. A sedum will be quickly killed by excessive wetness, especially standing water, which will accomplish what no drought can.
Even in the driest conditions, sedums practically never need further water after they are established. Sedums function admirably almost anyplace as long as they receive proper drainage, but they are particularly well suited for gardens in hot, arid regions like the western United States. They can also be found sticking up from boulders or sprouting from only a few inches of scree in cold, alpine environments where they are widespread. For almost every USDA Hardiness Zone, there is at least one Sedum species. The majority of creeping sedums can tolerate little shade but prefer full sun. Native to North America, Sedum ternatum is one sedum that prefers shade and a little bit more moisture than its relatives.
Creeping Sedums
Hardiness: The Northern Hemisphere’s Sedum genus has more than 400 species of succulent annuals, perennials, biennials, subshrubs, and shrubs. Sedums are commonly grown as creeping ground coverings. Each USDA Hardiness Zone has at least one species that can withstand it. Most thrive in Zones 4 through 9. OUTLINE: Five-petaled flowers in shades of yellow, white, or pink lie above mats of succulent leaves that range in color from green to blue-gray to reddish bronze. In the winter, the leaves of evergreen species take on colours of crimson and russet. PROPAGATION: From spring to midsummer, propagate plants by division or seed in the spring or fall. Plant in rock gardens, walls, recesses in walkways, and pots. You may also use it as a border edging or in sweeps on slopes. The majority of creeping sedums like full sun, although they can also tolerate little shade. They prefer medium to poor garden soil that drains well; once they are established, no additional watering is required. They cannot endure any amount of time in standing water.

Creeping sedums change from season to season
Creeping sedums are attractive for their dependability and lack of fussiness, but I’m also drawn to them for their succulent leaves, lengthy flowering cycles, and, in some cases, year-round attractiveness in the garden. Sedum blooms often come in little, star-shaped clusters that range in color from white to yellow to purple to pink, and are no larger than an inch in diameter and 4 to 5 inches tall. The carpets of blossoms they generate when planted in large numbers are stunning. Many evergreen sedums, such as Sedum album “Murale” and Sedum stenopetalum, blush to a rich red or bronze color in the fall and even throughout the winter. These stunning contrasts to an otherwise inert landscape last until early spring. They look particularly lovely on a snowy background.
One of the simplest plants to grow from seed, cuttings, or divisions is the sedum. Stem cuttings or divisions will guarantee the maintenance of a plant’s traits once you’ve found one you like because sedums don’t always grow true from seed. Sedums spread quickly, yet they are not invasive. They are easily lifted and transported because of their thin roots. As long as there is adequate drainage, they may survive the winter in most planters and come out of dormancy in the early to midspring.
I complained as I pulled boulders from the cultivated sections of my father’s fields as a young child working on the family farm in northeastern Maryland. In a fitting irony, decades later I still wander the same fields looking for fascinating stones to use as backdrops and accents for my ever-growing collection of sedums.
A few ways to use creeping sedums
Sedums that are resilient make lovely staples. In a section of my rock garden, I utilize a lot of sedums to simulate a cascade. You can blend several sedums, such as the white-flowered Sedum album, the S. grisebachii, and the yellow-flowered Sedum sexangulare (foreground, first photo below) (background). They perform well in a region that can be seen from above.
These year-round, low-maintenance plants are ideal for containers. You won’t need to bring the pots indoors for the winter because creeping sedums do well in containers. Additionally, because of their drought tolerance, you won’t need to locate someone to water them while you are away. Sedums, like the yellow-flowered S. sexangulare (Sempervivum spp. and cvs., Zones 410, second photo below), can be used as underplantings or in combination with other succulents like hens and chicks.
Make stepping stones or rock walls’ sharp edges softer. Within cracks in a stone wall or between stepping stones, sedums, like S. spurium ‘Fuldaglut,’ grow with almost no soil (third photo, below). Use small, mature seedlings, usually referred to as plugs, and combine with some fine gravel and soil.
Utilize a patchwork of sedums to tame a difficult terrain. Maybe you have a spot where gardening and lawn mowing have never worked well together, like a hillside with compacted soil. It might be the perfect place to use creeping sedums, like the pink-flowered S. spurium ‘John Creech’ and others, to intertwine regions of color and texture. The “quilt will vary three times a year as the sedums exhibit the colors of their early-season foliage, then their blossoms, and finally their winter leaves in various tones.
