How To Take Care Of Sedum In The Fall

Sedum spectabile Autumn Joy grows slowly but steadily until it reaches a height of 24 inches.

It has a rounded appearance and a spread of about 18 to 24 and listed as hardy to grow in USDA hardiness zones 3 to 9.

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.

Do I need to trim back my sedum in the fall?

Sedum plants, which belong to the Crassulaceae family, are popularly regarded as succulents that are simple to grow. There are many different shapes and sizes to pick from, making it easy to find the right one for your gardening project. Sedum plants don’t necessarily need to be pruned back unless they are becoming out of control and wild. Sedum plant pruning can sometimes enforce thicker plants and can control out-of-control development if you need a very neat appearance. Knowing when to prune sedum plants won’t harm them, but it will assist keep the starry flowers that most kinds produce.

Sedum can be pruned whenever you choose in warmer climates without damaging the plant’s health. However, the majority of pruning is done to get rid of the old flower heads and control the plant. On some of the slower growing species, pruning late into the summer may result in the removal of upcoming flower heads. Old flowers can always be taken out. The bloom head is a pleasing feature on some of the larger species, like Autumn Joy stonecrop, and it will continue through the winter. You have the option of taking these out in the fall or delaying your removal until the first few days of spring.

The leaf will wither and develop adorable small fresh rosettes in spring in colder climates. By pruning sedum plants to the new development, it encourages the emergence of this new growth and creates a more orderly plant.

Should I prune my sedum to prepare for 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.

How is sedum winterized?

The ideal course of action would seem to be to prune all of your perennials in the fall. I see why you would want to trim down the perennials and get ready for the upcoming Christmas season—you have lovely fall weather, you’re already raking leaves, etc. Unfortunately, our desires and the needs of our plants are not always the same. Here are some common queries about perennial winterization answered.

Depending on what you have planted in your garden, the process of effectively winterizing your perennials can frequently take place from late October into the first few weeks of spring. The most important thing when cutting perennials for the fall is to take your time.

A plant’s leaves are what give it life, so they should never be entirely clipped until after several hard frosts. It is possible for the plant to absorb the additional energy it requires by letting it naturally wither away. The plant moves its energy from the dying foliage to the roots, where it will be stored for the winter and used to grow a new, attractive plant in the spring. By pruning a perennial too soon in the fall, you run the risk of weakening it and having it perform poorly the next year.

The perennial variety will determine when to prune, but there are primarily 3 categories to consider:

  • After the deadly frost, thoroughly prune the tree.
  • In the spring or fall, prune to the base of the leaves.
  • Never prune in the fall (prune or clean up in spring)

1. After the fall killing frost, totally prune the tree. Although pretty self-explanatory, be aware that this process could happen at any time between mid-October and December.

  • When the foliage turns black, cut the anemone (Anemone x hybrid) to the ground.
  • When the beebalm (Monarda) dies back, cut it to the ground. Occasionally, if powdery mildew is a serious infestation, this may need to be reduced early.
  • Nepeta catmint should be cut down when the foliage turns brown.
  • Cut down Cranesbill (Geranium) when the foliage turns brown.
  • Hemerocallis daylily, cut to the ground as the leaf turns brown.
  • Cut Hosta (Hosta) to the ground once the leaf has withered.
  • Cut the iris (Iris sibirica) to the ground when the leaf withers or leave it for winter interest and trim it back in the spring before the new growth appears.
  • When the foliage dies back, cut the peony (Paeonia) to the ground.
  • Cut to the ground Sedum (Sedum) as the foliage dies back, or leave for winter interest and trim in the middle of winter or in the first few weeks of spring before new growth starts.
  • When the foliage on tall Phlox (Phlox paniculata) dies back, cut it back to the ground.
  • When the foliage on Threadleaf Coreopsis (Coreopsis verticillata) dies back, cut it back to the ground.

2. Completely prune in the spring or fall to the base foliage. A structure’s base is referred to as its basal. In its simplest form, basal foliage is fresh foliage that emerges at a plant’s base.

  • Susan the Black-Eyed (Rudbeckia) For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
  • Campanula (Bellflower): In the fall, prune back to the basal foliage.
  • Coneflower (Echinacea)
  • For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
  • Penstemon (Penstemon digitalis) should be pruned in the fall to the basal foliage.
  • Trim the stems of the Shasta Daisy (Leucanthemum) to the basal foliage in the fall, and then in the spring, only remove any leftover foliage.
  • In the fall, cut back yarrow (Achillea) to the basal foliage.

Avoid pruning in the fall (prune or clean up in spring). Some perennials simply benefit from having more leaf on top in the fall to protect the plant’s crown, but evergreen and woody perennials should never be cut back.

  • Aster (Aster) In the spring, before the emergence of new leaf, totally prune.
  • Before the new leaf emerges in the spring, fully prune the asters.
  • Monarch Butterfly (Asclepias tuberosa)
  • It’s not necessary to wait until spring to cut this back, but because it blooms later than most other perennials, it’s usually simpler to leave it alone so that it can freely reproduce. In order to avoid mistaking the new seedlings for weeds come spring, you’ll need to know where it was in your garden.
  • Although it is not required to wait until spring, Cardinal Flower (Lobelia cardinalis) benefits from the additional leaves on top to help protect the plant’s crown.
  • Camembert Pinks (Dianthus gratianopolitanus)
  • Simply remove the dried flower stalks and any untidy foliage in the spring after they bloom because these have evergreen foliage.
  • Coralbells (Heuchera) have evergreen foliage, so in the fall, cut the flower stems to the base foliage, and in the spring, tidy up the foliage as needed.
  • Invading Phlox (Phlox stolonifera)
  • Simply clean the foliage once the spring blooms have passed since these have evergreen foliage.
  • False indigo (Baptisia australis): Either leave the foliage for the seed heads, or cut it back completely as new growth starts to emerge in the spring by cutting back by a third in the fall.
  • Lavender (Lavandula)
  • Since lavender is a woody perennial, they only need a small amount of shaping trimming in the late fall or early spring. Avoid forcing growth before a frost by not pruning back too early; you want the growth to be hardened off so the frost won’t destroy it.
  • Before the chrysanthemum’s new foliage emerges in the spring, fully prune the plant. Mums benefit from having more leaves on top throughout the winter to shield the plant’s crown.
  • Rogue Sage (Perovskia)
  • Since Russian sage is a woody perennial, only a moderate pruning to shape them in the early spring is beneficial.

There are several exclusions to the guidelines, as there usually are with gardening:

  • Pruning down in the fall, Bearded Iris Although the leaves will still be green, they must be removed since the iris borer’s larvae are found there.
  • Decorative Grasses
  • When ornamental grasses are left uncut after dying back, they produce stunning winter interest in the garden. If you must trim back in the fall, be sure to wait until they have fully died back. Make sure to prune in the early spring before new growth appears if you do so. For information on how to prune the various grass varieties, click here.
  • RosesIf it has to be shaped, leave the rest and only chop down a third. Any severe pruning should be postponed until early spring, right before new growth emerges.

When pruning and cleaning up your garden in the winter, remember to always practice excellent garden sanitation. To try to contain and control the disease, make sure to remove all foliage from the garden and the ground if you know a plant is sick. In order to avoid unintentionally spreading any diseases, you should also routinely clean your pruners with rubbing alcohol or a bleach and water solution.

Although perennials need patience, the reward is definitely worth the effort!

When should sedums be reduced in size?

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.

Sedum can be divided in the fall.

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.

Sedum Care

Sedum plants, often known as stonecrop, do best in full sun, with little to no water, and, most critically, on soil that drains properly. For the flower bed and border, there are larger kinds that reach heights and widths of exceeding two feet. Old favorites for cottage gardens include “Fall Joy. Bright green, gray, and red ground cover kinds that spread swiftly and blossom in the early summer include “Angelina. everything in between as well! They are excellent container plants and do well in most gardens. Sedum plants feature succulent leaves that can be any color—gray, green, purple, blue, or even variegated—and can have anything from tiny needles to larger, fleshier leaves. Bees and butterflies adore them. The nicest part is that they are perennials and return year after year.

Here are a few expert recommendations for growing sedum plants that will look their best:

  • Use a well-drained soil at all times. If you’re planting them in containers, make the soil mixture very permeable by adding some shredded bark or sand. Grow them in raised beds and containers if your garden soil is heavy, or amend it.
  • Consider how the plants will feel while selecting your containers. To fit the modern vibe these plants exude, think concrete, stone, or simple round bowls if you want to create a succulent garden effect. However, don’t let that deter you from utilizing them in any type of garden—this is a fantastic way to modernize!
  • Although they can go without water for extended periods of time, I find that if they are in well-drained soil, they look their best with moderate watering and a little bit of drying time in between.
  • They don’t need rich soil or substantial fertilizers. Your plants will really become floppy with lots of stems but few leaves and blossoms if you overfertilize.
  • Although the larger kinds will fall over if they don’t get enough sun, they can tolerate some afternoon shadow.
  • Speaking of taller types, snip off the tops of the main stems in the spring when the plant is about six inches high. This will make the plant grow more tightly, which will solve the flipping over problem I stated earlier.

Try out various varieties of hen and chicks to plant with your sedums after you have the caring for them down. They are excellent sedum companion plants because they share the same needs for water and fertilizer. These are known as Sempervirens in Latin, so you can be sure you are purchasing the correct succulent. They look fantastic together in containers, as this image from “Sunset” demonstrates.
