Sedums have everything! This perennial produces clusters of star-shaped flowers that bloom from midsummer to fall, along with lush, luscious green leaves. It attracts pollinators and is simple to maintain. How to plant sedum in your garden is provided here.
About Sedum
Sedum, a genus of succulents with fleshy stems and succulent leaves commonly known as “stonecrop,” is one of the easiest perennial plants to grow. This sedum cultivar is suitable for practically all gardens because it is a hardy plant that thrives in shallow soil.
Based on how the plants develop, we like to split sedum into two primary categories: low-growing sedum and upright sedum.
- Sedum that grows slowly spreads throughout the ground and only grows to a height of a few inches (or less). As a result, they are ideal for use as ground covers along pathways, in rock gardens, or cascading over stone walls.
- Sedum that is tall or upright often grows in tall, upright clumps with dense clusters of tiny reddish-pink flowers in their huge flower heads. They make excellent candidates for border gardens or pollinator gardens due to their height and lovely blossoms. Despite upright sedum’s recent reclassification into the Hylotelephium genus, it is still frequently referred to as a “sedum.”
Although they prefer full sun, Sedum may tolerate partial shade. Plant sedum in full sun to enhance overwintering potential if you live somewhere with long, cold winters (Zone 5 and colder).
Although sedum thrives in sandy or poor soil, it needs to be well-drained to prevent fungus problems. If cultivated in soil that retains too much moisture, it is highly prone to developing root rot. Additionally, overly fertile soil can promote lanky growth, which can cause upright sedum species to bloom with a top-heavy appearance.
When to Plant Sedum
- Typically, sedum is purchased in plugs or pots and then planted in the garden. Sedum is best planted in the spring, after the risk of frost but before the summer heat arrives.
- In early spring, sow sedum seeds in average to rich soil that is well-drained. (Learn more about adding amendments to the soil and getting it ready for planting.)
How to Plant Sedum
- Depending on the kind, space plants anywhere between 6 inches and 2 feet apart. While upright sedums tend to keep more compact, low-growing sedums will quickly fill in any gaps.
- When planting whole plants or divisions, dig a hole deep enough so that the top of the root ball is level with the soil’s surface. Then, insert the plant, and then cover the area around it with soil. Avoid burying upright sedum stems in particular as this can cause rot.
- Planting cuttings: Sedum is easily propagated through cuttings, just like other succulents. Under the right lighting and watering conditions, the cutting should easily root if the cut end is simply inserted into the soil.
- Sedum plants require little maintenance once they are established. Check on your plants frequently over the summer to make sure they are not getting too dry, and water them (sparingly) if necessary. Sedum shouldn’t require extra watering if your area receives rain at least one every two weeks.
- After flowering, prune the plants to keep their shape or confine them to a single location.
- Advice: After blooming, leave upright sedum flowers alone for more winter interest. They will produce lovely seed heads.
- To stop your plants from spreading, remember to divide them in the spring or fall. Divisions and cuttings root easily all summer long.
- Sedum humifusum has stunning, bright yellow flowers and produces an excellent ground cover.
Do you plant sedum deeply?
As soon as you acquire bare-root sedums, inspect them for damage. The roots ought to feel strong to the touch and be a light beige tone. The packing material, which is typically peat moss or wood shavings, shouldn’t be too damp. If you see any mold on the roots, don’t panic. Get in touch with the nursery where you bought the plants if the roots are dripping and dark.
- The National Gardening Association claims that growing bare-root sedum has advantages over putting sedums in containers.
- As soon as the dirt can be turned over and isn’t too damp, they are prepared to be planted.
Shake off the roots’ packaging material. Remove any rotten or lengthy roots from your sedum. Put the roots in the water-filled bucket.
If you want to plant your sedum there, make sure it gets full sun. If the current soil needs drainage, turn it over and add sand.
Create a hole that is between eight and ten inches deep and eight inches wide. Fill the hole with the planting mix, combine it with the dirt already there, and thoroughly water. The National Gardening Association suggests using the soil in the hole to shape a cone. Give enough room for each bare-root sedum if you wish to plant more than one. While ground cover sedums should be spaced about a foot apart, tall sedums require around 18 inches between plants.
- Shake off the roots’ packaging material.
- If you want to plant your sedum there, make sure it gets full sun.
Removing the plant from the water The roots should be spread out and placed over the soil cone in the hole. Adjust the sedum so that the crown is just below the soil’s surface before adding soil back over it. The crown should be above the roots and below the area where the stems will eventually grow. There are sporadic little sedum rosettes.
Give the plant plenty of water. For the first week, water every other day; the following week, once a week for the first season.
How far can sedum roots travel?
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 is easy to plant in the ground.
Sedum, often known as “stone crop flower,” thrives in full to part sun. While creeping varieties can thrive in partial shade, taller hybrids require full light for the finest flowering.
Soil: Sedums prefer a pH range of neutral to slightly alkaline soil that is extremely well-drained. Root and stem rot can result from wet, heavy clay.
Tall growing sedums should be spaced 1 to 2 feet apart. Depending on the kind and how rapidly you want it to fill in an area, space low-growing, creeping sedums 6 to 12 inches apart.
Sedums should be planted in the spring after the risk of frost has passed. Till the end of the summer, you can still plant transplants in northern regions. Planting season is spring or fall in drier regions.
What is the rate of sedum spread?
Climate, soil type, irrigation, and fertilizing all affect how big and fast a plant grows. While fast-growing ground cover species like Sedum can spread up to 1″ each month during the growing season, slow varieties will stay neat and compact in a pot.
Who should plant Sedum?
Sedum is a plant that should be planted by everyone with a sunny garden and an eye for texture. Sedum plants are simple perennials that inexperienced gardeners with lots of sun may grow. Sedum comes in many different types, which gardeners who are looking for drought-tolerant plants for their landscape will undoubtedly want to include.
Where does Sedum grow best?
Succulent plants are sedum. Plants known as succulents store extra moisture in their stems, leaves, and roots. Similar to most succulents, sedum needs dry soil because of how they store moisture. Sedum grows best in areas of your landscaping that receive full sun and have soil that drains well. Despite having an exotic appearance, sedum may be cultivated in a variety of regions and many varieties are winter-hardy.
How to grow Sedum?
Sedum is frequently planted bare root or from potted plants. You can also introduce extra sedum to different areas of your yard by dividing it from an established planted area. Sedum is also frequently planted from leaf cuttings, however this method grows sedum in the landscape considerably more slowly. Sedum are succulent perennials that are best planted from pots or bare roots. The range of perennials and bulbs offered by Holland Bulb Farms now includes bare root sedum.
Sedums can be planted from bare roots from spring through summer since they can withstand hot and dry conditions. You can plant bare root sedum directly into the ground. Bare root sedum can also be started in pots and then moved to the ground once the top growth has become more established.
Sedum roots should be planted just below the soil’s surface. The soil should be at or slightly above the level of the crown of the roots, which is where all the roots converge and the plant will grow. When planting, spread the roots out and make the hole a little broader than it is deeper.
Do all Sedum spread?
In sunny areas like rock gardens, sedum are frequently planted as a ground cover. Not all sedum types, nevertheless, are planted as ground covers. Sedums that grow uprightly, such as Frosted Fire Sedum, Powder Puff Sedum, Night Embers Sedum, and Autumn Joy Sedum, do not spread. These upright types will maintain a tidy appearance and have a habit of clumping or mounding.
Rock gardens and boulder walls frequently contain ground cover sedum species as Dazzleberry Sedum, Firecracker Sedum, and October Daphne Sedum. These creeping sedum varieties are entertaining plants to include in a pot. Wherever you want the foliage to hang over the side of the pot, you can plant a variety of creeping sedum. I have a few planters with animals in them, including owls and frogs, and I used sedum to give them the appearance of hair.
How fast does Sedum spread?
When planting perennials, it is often advised to wait until their third year before planting them. When you plant ground cover sedum in your garden, this is true. The sedum may need up to three planting seasons to fully grow up and cover the space.
Do Sedum have flowers?
Sedum have unique foliage, and people frequently plant them for their texture and color. However, many sedum cultivars produce spectacular flowers in the middle to end of summer. Yellow, white, pink, purple, and other hues of sedum blossom. They are garden treasures with enduring seasonal interest because of the combination of their bright flowers and vibrant leaves.
Autumn The most popular upright sedum cultivar is Joy Sedum. It requires little maintenance and blooms in the late summer that are rosy pink before changing to rosy red in the early autumn. Little Miss Sunshine Sedum is a low mound-forming sedum that blooms in mid- to late summer with vivid yellow flowers. This low-growing sedum type does well in a rock garden as well as at the front of a planting area. Another low mound-forming sedum type with a summer-long cover of white blooms is called Bundle of Joy. The distinctive variety Super Star Sedum has vivid pink flowers on frosted green foliage. It looks beautiful planted in front of a garden border and maintains a great mound habit.
Are Hens and Chicks a variety of Sedum?
Unique succulents called Hens and Chicks are frequently offered with sedum. These low-growing, rosettes-producing plants belong to the Sempervivum genus, not Sedum. Hens and Chicks are not sedum, despite the fact that they are frequently planted and sold together. They look attractive when planted in rock gardens, planters, and boulder walls and may thrive in hot, dry climates. Hens and chicks perform best when planted in full sun with well-draining soil and are hardy in zones 3 to 8.
When ought sedum to be transplanted?
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.
