Meet Sedum Autumn Joy: The Star of Your Fall Garden

Sedum ‘Autumn Joy’ is a versatile and hardy succulent perennial, and it’s a true garden workhorse. It’s incredibly resilient, thriving across a huge range of climates (USDA hardiness zones 3-10) and is very drought-tolerant once established.

It’s a sun-loving plant that flowers best with at least 6 hours of direct sunlight. However, I’ve successfully grown it in a part-shade spot in my zone 6b garden, and the plant never skipped a beat. The one thing it demands is well-draining soil; it will not tolerate “wet feet” or anywhere water pools after rain.

This perennial grows into a neat clump about 12 to 24 inches tall and wide, making it perfect for the front or middle of a border. I love watching it change through the seasons: it forms beautiful chartreuse “broccoli” heads in summer, which then open to pale pink flowers and gradually deepen to a stunning rosy red as fall arrives.

It’s a fantastic choice for all kinds of garden styles, from formal beds to casual cottage gardens, and it even grows beautifully in containers.

Comprehensive Guide to Sedum Autumn Joy Care

Now that we’ve covered why you should grow autumn joy sedum, let’s dive into how to grow and care for it. Here’s what you need to know!

Sedum ‘Autumn Joy’ Planting Guide

‘Autumn Joy’ is my absolute favorite for a reason! It’s a tough plant that gives so much back! Here’s how to get it settled in your garden for those gorgeous blooms I love so much.

Setting Your Plant Up for Success

• Light: Give it full sun. This plant is happiest and produces the most flowers when it gets at least 6 hours of direct sunlight per day.
• Soil: The most important rule is well-draining soil. ‘Autumn Joy’ is adaptable but will not tolerate “soggy feet” or standing water. It performs best in moderately fertile soil with a neutral to slightly alkaline pH (around 6.5-7.5).

My Pro Tip: I always do a quick soil test before planting. It’s an easy way to see if you need to add any amendments, and it makes a huge difference in the plant’s long-term health and flower power!

How to Test for Soil Drainage: If you are unsure about your garden’s drainage, dig a whole about 12″ wide and deep and fill it with water to see how quickly it drains.

How to Plant ‘Autumn Joy’

You’ll most likely be starting with a nursery plant, which makes it super easy.

1. Water Well: Give the new plant a thorough watering to help settle the soil and eliminate any remaining air pockets.
2. Find the Right Spot: Choose a location in your garden that gets at least 6 hours of full sun.
3. Prepare the Bed: Loosen the soil with a garden fork to a depth of 12-15 inches. If you have heavy clay, this is the time to mix in organic matter like compost to improve drainage.
4. Dig the Hole: Make your hole about twice as wide as the plant’s container but no deeper.
5. Plant it: Gently remove the sedum from its pot and place it in the hole. The top of the root ball (where the plant stems emerge from the soil) should be perfectly level with the surrounding ground.
6. Backfill & Firm: Fill the hole back in with your soil, pressing down gently around the base of the plant to remove any large air pockets.

Watering Tips for Sedum Autumn Joy

When you first plant ‘Autumn Joy’, you’ll need to water it regularly to help it get established. The key is to keep the soil moist, but be very careful not to overwater—sedum hates soggy roots.

My personal approach is to plant in the spring or fall. Here in my garden, the temperatures are cooler then and we usually get enough rain that I can let nature do most of the work for me during that establishment period.

Once ‘Autumn Joy’ is established, it’s incredibly drought-tolerant. I honestly rarely water mine. I only give it a deep soak if we’re going through a long period of extreme heat or a serious drought. For the most part, normal rainfall is plenty.

Mulching

Apply a 2-3″ layer of mulch around the base of the plant to help retain moisture and suppress weeds. It is important to avoid piling mulch against the stems. Doing so, will prevent rot and keep rodents from damaging plants.

Sedum Autumn Joy Fertilizer

Sedum Autumn Joy does not need to be fertilized. Instead, focus on providing the plant with good-quality soil. Amend the soil with compost, and leaf mold, then top it off with some fresh mulch. Plant them in the proper location, help them get established, and these perennials can take care of themselves.

Deadheading and Pruning Back Sedum Autumn Joy

Deadheading sedum autumn joy is not necessary. Many gardeners cut their sedum back in fall when they do fall clean-up, but I recommend leaving the seed heads up until early spring to cut them back. The seed heads feed the birds and look so pretty when snow covered so I like to leave them be until spring.

Step-By-Step Guide to Dividing Sedum Autumn Joy

It is a good idea to divide sedum autumn joy every few years. Because over time, it can become crowded and lose their vigor. So dividing plants every 3-ish years can help rejuvenate them, keep them from overcrowding other plants, and promote healthier growth. Here’s how to do it:

• Timing: Early spring or early fall, when the plant is not blooming and temperatures are cooler. I prefer to divide my sedums in the fall because its the end of the season and their roots will have time to establish through the winter in the spring.
• Prepare: Water the plant thoroughly the day before dividing to reduce transplant shock.
• Dig: Use a garden fork or shovel to carefully dig around the plant, 6-8 inches from the base. Gently lift it out, keeping the root system as intact as possible.
• Clean: Shake off excess soil or use a hose to rinse the roots.
• Divide: Look for natural divisions in the root ball, usually where stems emerge. Cut the root ball into smaller sections, ensuring each has several stems and ample roots.
• Plant: Choose new locations with well-draining soil and full sun to partial shade. Dig holes slightly larger than the root sections, plant, and water thoroughly.
• Mulch: Add compost or mulch around the new plants to retain moisture and provide nutrients.

Planting Sedum Autumn Joy in Pots

Sedum Autumn Joy is well-suited for container gardening due to its drought tolerance and compact growth habit.

• Container: Choose a pot at least 12 inches in diameter with drainage holes.
• Soil: Use a well-draining mix of standard potting soil, perlite, and coarse sand. Avoid heavy garden soil.
• Planting: Fill the container, leaving space for the plant. Gently remove the sedum from its nursery pot, loosen the roots, and place it in the center. Fill in with potting mix and firm gently.
• Location: Place the pot in full sun for at least 6-8 hours daily.
• Watering: Water thoroughly but allow the soil to dry out between waterings. During hot weather, daily watering may be needed. Water at the base of the plant early in the day to reduce pest and disease issues. Consider using a drip irrigation system.
• Fertilizer: Sedum Autumn Joy requires minimal fertilization. A light application of a balanced, slow-release fertilizer in the spring will provide sufficient nutrients for the growing season.

Winter Care for Sedum Autumn Joy in Pots

Before planting in your pot, insure that it is one that can handle the freezing and thawing moisture and temps of winter. Avoid planting them in terracotta, concrete or other pottery as they tend to crack during the cold, wet, winter months.

If you want your sedum autumn joy in pots to survive the winter, choose a variety than can handle two zones colder than your current hardiness zone. This means, if you live in zone 6, you’ll want to ensure the variety you grow can handle zone 4.

Another option is moving the pot to a sheltered location or insulating it with mulch or bubble wrap. You can also try bringing the pot indoors to a cool, bright area to overwinter and water it minimally.

Or you can dig them out of their pots and plant them directly in the ground to overwinter there (this is what I would do). When spring arrives, they can be left where you planted them or potted back up in your planter!

Sedum Autumn Joy Pests and Diseases

Sedum Autumn Joy is known for being a hardy and low-maintenance plant, but it can occasionally encounter some pests and diseases. Here’s how to identify and manage the common issues that might affect your Sedum Autumn Joy.

Common Pests

Aphids are small, soft-bodied insects that can cluster on the stems and leaves, sucking sap and causing distorted growth. You can often spot them by the sticky honeydew they leave behind. To manage aphids, spray the plant with a strong jet of water to dislodge them, or use insecticidal soap or neem oil if the infestation is severe. Encouraging beneficial insects like ladybugs, which are natural predators of aphids, can also help.

Slugs and snails can chew holes in the leaves, especially in damp conditions. To manage these pests, use slug and snail traps or apply a layer of diatomaceous earth around the base of the plant. Keeping the garden area free of debris and mulch where slugs and snails can hide is also beneficial. I haven’t had this problem at all in my New Jersey gardens and I’ve been growing them for almost 30 years now.

Scale insects are small, oval pests that attach themselves to the stems and leaves, appearing as tiny bumps. They can cause yellowing and wilting. To manage scale insects, remove them manually with a cotton swab dipped in rubbing alcohol, or apply horticultural oil to smother them. Similar to slugs and snails, I haven’t had this issue in my gardens to date.

Common Diseases

Root rot is a fungal disease that occurs when the soil is poorly draining and remains too wet, causing the roots to decay. To manage root rot, ensure the plant is in well-draining soil. If you suspect root rot, remove the affected plant, trim away the diseased roots, and replant it in a well-draining medium.

Powdery mildew presents as a white, powdery coating on the leaves and stems, typically in humid conditions with poor air circulation. To manage powdery mildew, improve air circulation by spacing plants appropriately and avoid overhead watering. Fungicidal sprays like neem oil can help if the problem persists.

Leaf spot is caused by various fungal pathogens and can lead to spots on the leaves, causing premature leaf drop. To manage leaf spot, remove and destroy affected leaves to prevent the spread of the disease. Fungicides may be necessary for severe cases.

General Prevention Tips

• Proper spacing: Ensure adequate spacing between plants to improve air circulation, reducing the risk of fungal diseases.
• Watering practices: Water at the base of the plant early in the day to allow foliage to dry before nightfall, which helps prevent fungal infections.
• Clean garden practices: Regularly remove dead or decaying plant material from the garden to eliminate habitats for pests and disease spores.
• Healthy soil: Maintain healthy soil through regular amendments and by ensuring proper drainage to prevent root-related diseases.

I’ve been growing this plant for over 25 years and can tell you that I’ve seen little to no problems with them if they are planted in full sun and well-draining soil. You’ll notice some yellowing or weak growth if it’s overwatered or grown in soil that is waterlogged.

If you treat it right, this plant will take care of itself. I highly recommend this easy-care perennial plant for beginners or those who want to grow flowers but have little time. By staying vigilant and addressing issues promptly, you can keep your Sedum Autumn Joy healthy and thriving with minimal effort.

Sedum Autumn Joy FAQs

I get lots of great questions about growing autumn joy. Here are the most popular FAQs.

Is Sedum Autumn Joy a Perennial?

Yes, Sedum Autumn Joy is a perennial plant, which means it comes back every year. This is one of the fantastic qualities that makes it a popular choice among gardeners. Once established, it will go through its growth cycle each year, gracing your garden with beauty season after season.

When we moved to our former family home over 23 years ago, we had a sedum joy plant near the road that I divided almost yearly and it still lives after we moved. They can live a really long time so they are a great investment!

Does Sedum Autumn Joy Like Sun or Shade?

Sedum Autumn Joy is a sun-loving plant that needs full sun to truly thrive. This sunny exposure helps the plant develop its vibrant colors, strong stems, and robust growth. However, it can also tolerate some morning or afternoon shade. From my experience, I’ve grown it successfully in partial shade in my zone 6b garden.

Does Sedum Autumn Joy spread?

Yes, Autumn Joy sedum has a natural tendency to spread over time. It forms clumps of rosette-like growth that gradually expand, creating a fuller and more visually appealing display. This spreading habit can be an advantage, as it helps fill in gaps in your garden and creates a lush, textured look.

However, the spreading of Sedum Autumn Joy is relatively slow compared to some other ground-covering plants. You won’t need to worry about it taking over your garden quickly or becoming invasive.

To keep the plant’s vigor, divide the clumps every few years. This not only keeps the plant in check but also provides you with new plants to place in different areas or share with fellow gardeners.

Should Autumn Joy Be Cut Back, And If So, When?

Trimming back Autumn Joy sedum is a beneficial practice that helps maintain the plant’s health, appearance, and overall performance. While it can be cut back in either late fall or early spring, I recommend waiting until early spring. The flowers give the garden winter interest, especially when snow-covered, and the seeds also provide a food source for birds.

Is Sedum Autumn Joy Pollinator Friendly?

Autumn Joy sedum is an excellent pollinator plant. Its nectar-rich flowers make it highly attractive to a variety of pollinators, including bees, butterflies, and other beneficial insects.

The late-season blooms of Sedum Autumn Joy provide a valuable food source for these pollinators, especially during a time when many other flowering plants may have finished blooming.

Is Sedum Autumn Joy Deer Resistant?

While some gardeners consider it to be deer resistant plant, I am not one of them. Deer have nibbled on mine and so I spray them with deer repellent early on in the season to teach them early that they don’t like the taste of my sedums.

How Do I Propagate Sedum Autumn Joy?

If you want to increase your stock and maintain plant health, the most common method of propagation is division.

Here’s how to do it:

• In the spring or early fall, dig up the entire plant, including its root ball.
• Gently separate the clumps of the plant by pulling them apart, using a knife or spade shovel if needed.
• Replant the divided clumps in well-draining soil at the same depth as the original plant.
• Water the divisions thoroughly and keep them well-watered until they establish new roots.

While this is the most common method, you can also propagate the plant by cutting a flower stalk and stick it in the ground or pot with well-draining soil. Leave it undisturbed and it will eventually root. That’s it!

I’ve done this numerous times and it’s even easier than dividing. Keep in mind that it will be a small plant because you only planted one stalk. But trust me, this works.
