Sedum mats are one of our nursery’s greatest multi-taskers, so we’re happy to welcome them to our virtual greenhouse for the first time. Each mat is produced from a species of sedum that is densely planted and has a range of colors and forms, offering a creative solution to various gardening problems. The mats are perfect for unique places like vertical wall plantings, green roofs, and rock gardens since they are easy to customize and maintain. The lightweight coconut fiber in which the sedum plants are rooted is excellent for airflow and water retention, making the mats perfect liners for open planters like the hayrack in the picture above.
Karen C., a plant buyer, says: “Because the sedum mats are pre-planted and cultivated in a soil/netting media, they are incredibly versatile and may be grown in any direction. Additionally, the variety of plants allows them to tolerate different light conditions, but full sun is ideal. Sedum can tolerate low moisture levels, but it should never be allowed to dry out completely. Simply cut your sedum mat to the appropriate size with garden shears, then set it sedum-side down in the container to use it as a living liner for a rack or basket. You are now prepared to plant after adding a layer of dirt on top. The sedum then holds onto the water while providing enough of drainage and aeration.”
How is a sedum mat cut?
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.
Describe the sedum mat.
SOPRANATURE A variety of sedum species that have been pre-grown in a growing medium and are supported by a non-woven polyester matrix make up SEDUM MATS. The sedum species can adjust to the local climate and hardiness zone.
How is sedum kept upright?
Sedum plants respond well to pruning and usually become bushier in the next spring growth spurt. In the early spring, trim the stems down to within an inch (2.5 cm) of the soil using sharp pruners or garden shears. Be careful to stay away from the emerging new growth.
Plants that are pinched will get bushier. If you pinch the new growth off close to the soil, it will grow thicker and form a more compact stem.
Low-light sedum succulents may benefit from pruning in order to develop a stronger stem. Retrim the stem to 6 inches (15.2 cm.). The stalk will thicken and support the flowers when they do bloom, but you will delay any blossoms.
If your sedums are too densely packed on top, remove the blossom and bring it inside so you can enjoy it as a cut bloom. They are delightful both inside and out.
Should the sedum be pruned in the winter?
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.
What transpires within a sedum roof?
In order to add green space and aesthetic variety to an urban setting, green roofs are growing in popularity. In addition to many other advantages, they enhance air quality, offer wonderful habitat for wildlife, decrease water runoff, and stop gutters from overflowing.
Smaller tasks like building a garden shed or a garage roof can be completed by almost anyone. In addition to making your garden or home seem better, adding a green roof area gives you a powerful tool for combating the consequences of climate change.
1. Lightweight ExtensiveThe most basic and low-maintenance type of roof uses sedum plants.
2. ComprehensiveThe one we like! utilizing a combination of wild flowers and sedum. more fauna is supported than only sedum.
3. Moderately intensive—more akin to a garden than a roof. utilizing a combination of small shrubs, herbs, and ornamental plants. construction is difficult and requires skilled assistance.
Step by Step Guide
Verify that your building is solid, watertight, and capable of supporting the weight of the green roof. A basic, light-weight green roof will typically weigh 60 to 150 kg per square meter; this weight will rise when the roof becomes saturated with rain or snow. Consult a structural engineer or architect before you begin if you are doubtful of the building’s or shed’s ability to withstand structural loading.
How angled should my green roof be? Both flat and pitched roofs can be transformed into green roofs. A green roof should ideally be placed on a slope of up to 10, but if the slope is greater than 20, you should have a structure to prevent the green roof from sliding.
Your shed or garage needs to be waterproofed in layers first. Most sheds already have a layer of bituminous felt, but the best way to stop water or roots from getting through is to use a material like heavy-duty rubber pond liner.
Include a plant protection fleece, which may be obtained in a roll from a nearby garden retailer, to shield the pond liner during assembly.
Create a frame out of lightweight metal or rot-resistant wood. The frame must be at least 100mm deep, the same depth as the substate (soil). You can construct the frame by simply nailing the corners together or by forming the corners with “L” brackets. The substrate (soil) and plants will be held in place by this, and rainwater will be able to flow out without the substrate getting flooded.
Make sure to add holes to the side of the frame closest to the ground so that water may drain from the roof, or else make sure there is a 10mm space between the roof and the frame.
Because the recommended plants, such sedum, wildflowers, and herbs, don’t root deeply, extensive green roofs don’t need to be deep. A soil depth of at least 100mm is recommended as a general rule of thumb. For instance, 20mm of pre-vegetated mats and 60mm of substrate (soil).
To ensure that water may drain freely if your roof is flat (or up to 5), add a thin 10mm layer of pea gravel over the plant protection fleece.
Utilize a sizable, light-weight substrate for green roofs that is intended for sedum or wild flowers, which need between 70 and 200 mm of depth in the substrate to take root. To lessen the weight placed on the structure, the soil must be light. Our lightweight substrate for green roofs comes highly recommended.
Either pre-vegetated mats or direct planting are options. The ideal plants to use are sedum plants, herbs, wildflowers, and grasses because they are more hardy than most and still draw a variety of species. When planting or installing sedum, keep in mind that the plants at the top of the roof will receive less water than the plants at the bottom.
- By holding onto water, green roofs lower the risk of flooding because less of it drains into urban areas.
- Green roofs insulate the roof throughout the winter, which helps a building retain heat. A green roof will also block the sun’s rays in the summer, keeping the interior cool. a natural air conditioner that might be able to completely transform your garage.
- Wildlife may come to your region if you have green roofs. If you have a small garden, any more planting space wouldn’t hurt. Find out what kind of wildlife you want to draw, then grow flowers that would appeal to them.
- In order to guarantee drainage exits are clear, plants are irrigated during the dry season, and bare areas are replanted, green roofs only require maintenance twice a year.
Are sedum tiles contagious?
Give your newly planted sedum and dormant plants a few inches of room. The sedum will spread to fill in any gaps as it grows. Do not plant on top of dormant bulbs.
What is it that makes a sedum green roof succeed or fail?
Actually, there are a lot of aspects. Design, installation, upkeep, and occasionally (albeit infrequently) just plain poor luck. But as a general guideline, the technique to guarantee a sedum green roof is to comprehend the layers of the build-up and how they interact. It can be dangerous to combine and match components from various build-ups. The parts of each manufacturer’s green roof build-up will have undergone extensive testing to ensure that they function as a unit. Mixing and matching is equivalent to attempting to fit Land Rover components into a mini; it may or may not succeed.
Sedum Roof BuildUpDesigning a sedum roof build-up
If the aspect is ideal—with lots of sunlight, a gentle slope, and protection from ferocious winds—and the suitable build-up has been erected. A basic maintenance schedule should ensure the success of a sedum green roof.
What components are needed?
A green roof is more than just mud and seeds. Sedums are tenacious, small plants with enormous hearts that will attempt to thrive wherever. However, poor drainage and shade are two things they cannot stand.
The roof’s orientation and its proximity to larger structures and trees are what cause shade. The accumulation of the green roof cannot control it.
A drainage layer, a way to collect enough rainwater for the plants to live, a growing medium, and of course sedum plants are required for a sedum green roof.
building up a sedum green roof. Following are the items in ascending order:
- waterproofing;
- protecting waterproofing using polyethene;
- a drain mat,
- water-holding mat;
- Sedum matting made by Enviromat
Sedum Roof BuildUpManaging Rainwater on a Green Roof
The majority of roofs have some slope to them. Even a “A flat roof has a slight fall to enable drainage. That is crucial. Prior to installing the green roof build-up, you should take care of any puddles that remain on the area where your planned green roof will be located for longer than 24 hours following a downpour.
Traditional waterproofing is layered on top of the green roof build-up. Prior to putting in any of the layers of the green roof, make sure that it watertight.
For a “flat roofing. Specifically, one with a slope of less than three degrees. It’s critical to begin the construction of your green roof with a layer of drainage matting. This layer is not required if the slope is larger than three degrees.
Sedum Roof BuildUpIrrigation vs water retention
The sedums on your green roof can withstand severe droughts and detest having wet feet. However, because they are living organisms, they do require access to water. Just don’t do it in excess.
- Install a system of irrigation so you can water the plants during extended dry spells (you will need to water them regularly for the first few weeks after installation anyway)
- Put a layer of water-retentive material on the roof so that the substrate is kept dry while the plants have access to some water.
The second option might entail employing water retention matting or a thick layer of growing material.
It is best to have deep substrate. It’s difficult to raise onto the roof, though, and once there, it can place a considerable load on the structure. Excellent if the structure has been built to handle the weight. If you’re unsure, seek professional counsel.
In most cases, water retention mats can be purchased at the same time as sedum mats. In fact, the water retention mat is already attached to the back of Enviromat All-In-One Sedum Matting. That keeps you out of a job!
The final flourishsedum plants
You can hydroseed or plug plant your sedums straight into the substrate if you’re using the substrate system. Or you may use a sedum blanket, also known as sedum matting, which already has the plants established and flourishing. The mat only has to be spread out and watered. It may be placed directly on the substrate, the drainage mat, or the water retention mat. Simple.

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.
