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.
Fall pruning of Autumn Joy sedum is necessary?
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. Cut back sedum plants by half in late spring or early summer to prune them (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.
When should I trim Autumn Joy the sedum?
Spring – You should prune the plant back to the earth in the early spring. The new growth will be able to appear as a result. To remove the stems, chop them using pruning shears.
Summer: You might want to prune the plant by halving in May or June. A plant that has become excessively hefty and lanky will benefit from this. Make a clean incision at a point in the stalk that is immediately above a row of leaves. Don’t worry; fresh flowers will grow on the stems that were clipped.
Fall – Anytime is a good time to prune for maintenance. You might occasionally need to remove unhealthy or dead growth. Trim dead stalks back to the healthy portion or the soil’s surface.
Winter: Prevent pruning during the bitterly cold or extremely hot months. The plant is under the most stress at this time.
For the winter, should sedum be pruned back?
As soon as the blooms start to fade in the winter, you can trim the sedum back, or you can wait until the ground turns green in the spring. Use pruning shears to cut the entire plant back to the ground, or break the stalks by hand at the ground level. The sedum will reappear from the roots in the spring.
Does the sedum Autumn Joy return each year?
Its average overall height is 24 inches (2 feet) tall. The entire plant has a rather rounded form and will eventually reach a width of between 18 and 24 inches (1 1/2 to 2 feet). Although it may also expand to a height and width of up to 3 feet from 1 foot.
Autumn Joy Sedum can thrive in a variety of climates and temperatures, including scorching heat and freezing winters. It will begin to die back after being exposed to the first few frosty touches and then lay dormant for the remainder of the winter. As long as high levels of humidity don’t cause the soil to hold an excessive quantity of moisture, it will thrive in locations with varied humidity levels as well. If it does, the roots of your plant might rot, which would cause the remainder of the plant to wilt and begin to die.
Autumn As a perennial plant, joy sedum grows year after year. In warm climates, the leaf dies back to the ground, but this plant sprouts new growth every growing season in the spring. These flowering plants are very good at taking care of themselves, so they won’t require a lot of extra care or attention. They should persist for a very long period as long as you put them in a decent spot and keep an eye on them occasionally.
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.
How should sedum be cared for?
Sedums often fall into one of two categories: clumping or creeping. Clumping hybrids reach heights of 1 to 3 feet. Creeping types stretch out a few feet in each direction while remaining close to the earth. Both varieties have tiny, vivid flower clusters and succulent foliage. Depending on the variety,sedums bloom from summer till fall. The flowers are beautiful and stand out from the foliage on clumping varieties. A garden can become a carpet of color because to the profusion of blooms that creeping types can produce.
Staking: Creeping sedum variants do not require staking. If plants receive insufficient sunlight, receive too much nitrogen fertilizer, or grow old, clumping kinds can become floppy. Wrap the plants in twine or a thin metal wire before they bloom in order to keep your clumping sedum upright, especially when it is blossoming. Additionally, clumping species can be planted next to other strong perennials, like dwarf asters, or in groups to support one another.
Sedums need less water because they are drought-tolerant succulents. Keep newly planted sedums moist for the first year after planting. They should grow successfully without any extra watering after they are established. In fact, sedum stems and roots can rot and die from getting too much water. Because of this, sedums require well-drained soil to remain healthy.
Sedums can grow on low-fertility soils with fertilizer. Clumps of plants may flounder and flower later in a soil that contains too much nitrogen. To maintain your sedums growing and blooming well, just add a layer of 1 inch thick compost when you plant them and once a year in the spring.
Mulching: Because sedums require well-drained soil, bark mulch should only be used sparingly as a weed barrier. To avoid rotting, keep organic mulches away from the plant’s crown. In rock gardens, sedums look fantastic, thus mulching the soil with gravel not only looks good and keeps the soil moist but also keeps the soil well-drained.
Sedum leaf blotch
Botrytis is the reason for the brown leaf blotches on Sedum leaves. Gray mold is another name for Sedum leaf blotch.
Both the foliage and the flowers are impacted by this fungus infestation. On the leaves of the afflicted plant, there are dark, circular blemishes.
Both the leaves and the stems have the brown markings. The diseased plant’s blossoms become brown. Early detection of the infection may still allow for recovery.
To get rid of the fungus, use a sulfur- or copper-based fungicide to the afflicted Sedum. Early on in the infection, this is effective.
Discard the sick plant if the infestation is severe and you are unable to treat it.
Powdery Mildew on Sedum
A fungal illness known as powdery mildew causes a white covering to develop on the leaves of Sedum plants.
Sedum leaf surfaces have brown blemishes or patches. If you look closely, this might resemble one of those leaf spot disorders.
On the afflicted Sedum, you can discern chains and threads of white mold. Only these whitish outgrowths are initially visible.
As soon as you notice the white threads on your Sedum, take action. Neem oil can be sprayed on infected Sedum plants to get rid of powdery mildew.
You must give your Sedum more effective treatment if the condition has advanced.
In a gallon of water, combine 1 tablespoon of baking soda and 1/2 a teaspoon of liquid, non-detergent soap.
What causes my sedums to droop?
Floppy sedums making you antsy? The appropriate position and a little care can enhance their beauty and lighten your workload.
Sedums prefer full sun and well-drained soil, especially the perennially well-liked Autumn Joy. When cultivated in the shade and in too moist soil, they frequently flop.
If necessary, relocate your plant to a sunny area with sufficient drainage. If your soil is heavy clay, add organic matter to it to boost drainage and your growth success.
Avoid fast-release fertilizers with high nitrogen levels since they tend to fail to encourage luxuriant succulent growth. If your plants require a nutritional boost, use Milorganite, a low nitrogen slow release fertilizer.
It’s time to break out the pruners if the plants are still failing. When plants are 8 inches tall, cut them back halfway. or remove the developing tips with a pinch. This promotes more dense development. Although the flowers will be smaller, you will have more to appreciate.
A little additional information: Pruning in the early season is a practical method for promoting more sturdy, compact growth on many late-season perennials. A few examples include Russian sage, coneflowers, asters, and mums.
How does sedum survive the winter?
Since most sedums are quite hardy (check your plant tag to see the hardiness zone), if they are in a pot that can withstand the rigors of winter, you can leave them outside.
Remove the foliage and compost the leaves after it dies in the late fall or winter (discard any leaves that are diseased). For the winter, place the pot in a protected area. Ideal location is adjacent to a building in a shaded area. Some people think it’s a good idea to place the pots in the sun, but this is actually counterproductive because perennial plants’ roots can suffer greatly from unseasonable thaw/freeze cycles that can occur all winter in pots placed in the sun. Instead of repeatedly going through thaw/freeze cycles, which have the consequence of rupturing the root tissues, perennial plants are much better off being frozen for the whole winter. With many cases, pots that are covered in snow during the whole winter fare better than those that are left open to the elements.
In any case, be aware that plants overwintering in containers will endure extremely cold temperatures due to their constant exposure to chilly air. Make sure the plant is rated for two USDA zones cooler than the one where you reside if you plan to leave it in its pot. For instance, pick species rated for zone 4 if you live in zone 6. Additionally, you can shield them by wrapping the pots with burlap. Some gardeners even completely bury the pots in the ground to shield the roots from harsh temperatures for the winter before digging them out again in the spring.
