Learn how to grow sedum ‘Autumn Joy’ with these helpful hints.
‘Autumn Joy’ sedum, like other members of the sedum family, stores water in its fleshy, thickened leaves. This sedum, like hen-and-chicks (Sempervivum tectorum) and jade plant, is a succulent (Crassula ovata). All of these plants have water-hoarding leaves that thrive in arid, low-fertility soil. A compost-rich garden soil, on the other hand, can be a death knell for these water-conserving plants.
In rich, healthy soil, sedum ‘Autumn Joy’ responds with lush growth, resulting in weak, floppy stems. Clumps that start the growth season tight and upright but conclude with bowing and flailing stems are a regular occurrence for gardeners with this long-season performer. Keeping the soil light and lean is one way to avoid stem flop. If you’re planting in rich garden loam, consider adding a shovel of sand to the planting holes.
Inserting hoop or grow-through type stakes around plant clumps early in the season is another strategy to keep ‘Autumn Joy’ sedum stems standing soldier straight. If the plants aren’t in full sun, the stems will also flop. All sedum plants, including the sedum ‘Autumn Joy,’ require sunlight to thrive.
Many gardeners prune ‘Autumn Joy’ stems back in the spring and summer to encourage plants to grow to a reduced overall height. Pruning also results in shorter, more branched stems. Cut sedum plants in half in late spring or early summer to trim them (June in most places). Pruning causes the sedum ‘Autumn Joy’ to flower later, resulting in a longer flower show in the fall.
In the summer, the sedum ‘Autumn Joy’ produces flower buds atop stalks. The buds are chartreuse for a long time, bringing interest to the summer garden. The green buds open in late summer, revealing pink flowers that linger about six weeks in the garden. The blossoms become a bronze color before turning an almost chestnut brown that stands firm under winter snow. For visual pleasure, many gardeners leave flowers in the garden throughout the winter.
The colorful blossoms entice pollinators of all types. As a late-season nectar source, sedum ‘Autumn Joy’ is an excellent addition to a wildlife or butterfly garden. Its blooms supply bees, wasps, and other pollinating insects with large landing platforms.
The sedum ‘Autumn Joy’ is hardy in zones 3 to 8. This fall staple is also available in a variety of various formats. Light pink blooms bloom atop green foliage on the traditional sedum ‘Autumn Joy.’ Similar blossoms on stems with variegated, white-edged green leaves can be seen on the sedum telephium ‘Autumn Charm’ (Sedum telephium ‘Autumn Charm’). Autumn Fire (Sedum spectabile ‘Autumn Fire’) is a better version of ‘Autumn Joy.’ ‘Autumn Joy’ is gradually being phased out of the market. ‘Autumn Fire’ features larger flower heads, stronger stems, and a longer flowering window than ‘Autumn Joy.’
Should I cut back sedum for winter?
Tall sedum varieties like “Autumn Joy” (Sedum x “Autumn Joy”), which thrives in USDA zones 5 through 9, flower all winter and need to be pruned in late winter or early spring. Cut the sedum back in the winter as soon as the blossoms fade, or whenever you see green peeping through the ground in the spring. Using pruning shears, cut the entire plant back to ground level, or break the stalks at ground level by hand. The sedum will reappear from the roots in the spring.
Should you cut back sedum in the fall?
Sedum plants are succulents that belong to the Crassulaceae family and are considered easy to grow in most climates. There are numerous sizes and varieties to pick from, making it possible to find the perfect form for practically any gardening project. Cutting sedum plants back isn’t technically necessary unless they’re growing out of hand. Sedum plant pruning can restrict errant growth and, in some situations, enforce thicker plants if you desire a highly neat appearance. It won’t kill the plant, but pruning sedum plants at the right time will help maintain the starry flowers that most varieties produce.
Sedum can be pruned at any time in warmer areas without affecting the plant’s vigor. The majority of pruning, on the other hand, is done to remove old flower heads and keep the plant in check. You risk removing future flower heads on some of the slower-growing varieties if you prune late in the summer. At any moment, old flowers can be removed. The bloom head is an appealing feature on some of the larger species, such as Autumn Joy stonecrop, and it will last throughout the winter. You have the option of removing these in the fall or waiting until early spring to do so.
In cooler climates, the leaf will die back in the winter and be replaced by beautiful small fresh rosettes in the spring. By pruning back sedum plants to the new growth, it aids in the emergence of new growth while also forming a more neat plant.
When can you split sedum plants?
You should know how to divide sedum so you can spread more of these attractive plants, whether you have little spreading rosettes or towering Autumn Joy stonecrop. Sedums thrive in hot, dry climates and bring lively color and quirky form to difficult-to-plant regions. Sedum separation is a simple project that will quickly increase the number of easy-to-grow plants. New divisions form quickly and require little more attention.
Late fall to early spring is the best time to divide perennial perennials. When you know when to divide sedum, you can ensure that it recovers quickly and roots well. Because many sedum plants die back in colder climates, determining where the plant is until new growth appears in early spring can be difficult. It is best to separate the plants at this time.
Plant division can increase blooms and improve plant health. Every three to four years, sedum should be divided. Some growers advise dividing the plant after it has blossomed and while it is still developing. Although recovery will be longer, these resilient small succulents should be able to bounce back rather quickly.
Can sedum survive frost?
Succulent plants that thrive in zones 3 to 9 are known as sedums. Because succulents are notorious for holding water in their leaves, sedum is one of the most hardy succulents available. Sedums can withstand heat, dry soil, and cold temperatures. Sedum, unlike most perennials, does not require much attention during the winter.
Sedums can be neglected as you prepare and prune your garden for the winter. Sedums are hardy plants that can withstand cold and temperatures below freezing. The remaining stalks with spent flowers will provide color and food for the birds as the upright sedums fade back to the ground. You can cut the stalks to the ground if you want. It will not affect the plant or its new growth in the spring.
Does Autumn Joy sedum spread?
Late in the summer, flower stalks with many buds grow, like broccoli. Individual 1/2-inch wide star-shaped flowers make 6-inch-wide flower heads. The stunning pink flowers grow to a rosy-orange color and have robust stems that can be used as cut flowers. Seed heads add interest to the garden in the fall and winter, as well as attracting birds and being utilized in floral arrangements. Once established, ‘Autumn Joy’ is drought resilient due to the water stored in the succulent stems, leaves, and roots.
How do you keep sedums small?
Sedum plants respond well to pruning, and in the next spurt of spring growth, they tend to develop a bushier plant. In the early spring, trim the stems down to within an inch (2.5 cm) of the earth using sharp pruners or garden shears. Take care to stay away from the fresh growth that is forming.
Pinching encourages plants to grow more densely. Pinch off new growth near the soil to create a more compact stem with thicker growth.
Pruning sedum succulents that are growing in low light might help them develop a stronger stem. Trim the stem to 6 inches in length (15.2 cm.). You won’t get any blooms for a while, but the stalk will thicken and sustain the blossoms when they arrive.
Finally, if your sedums’ tops get too heavy, cut the flower and bring it indoors to enjoy as a cut bloom. They’re a delight both inside and out.
