Every fall, usually beginning around mid-September here at our Maryland nursery, we start getting familiar questions from customers.
"Why are the leaves turning yellow?" "Why does my perennial look different from the website?" "The leaves are red or brown. Is my plant dying?" "My plant arrived with very few leaves. Is it healthy?"
I completely understand the concern. When you order a plant online, you naturally hope to open the box and find a plant covered in beautiful green foliage. But plants are living things, and by September and October, many of the trees, shrubs, and perennials growing here in Maryland have already begun to respond to the changing season.
They're going dormant.
That doesn't mean the plant is unhealthy. In many cases, it means the plant is doing exactly what nature designed it to do.
Dormancy Starts Before the Leaves Fall
Dormancy doesn't suddenly begin when the last leaf drops. The process starts much earlier.
As summer transitions into fall, days grow shorter, nights cool, sunlight changes, and plants begin to receive signals that the growing season is ending. Instead of putting energy into tender new growth, they begin preparing their stems, crowns, and roots for winter. That means a plant can still have leaves even while it's already well into dormancy. (For more on why this rest period matters, see our article on the importance of dormancy to plants.)
Why Nursery Plants May Go Dormant Earlier
Plants growing in nursery containers experience fall differently from plants growing in the ground.
A landscape plant has its roots surrounded by a huge volume of soil. That soil changes temperature relatively slowly and provides considerable insulation. A nursery container holds much less soil and is exposed to fluctuating air temperatures. When September nights become cooler here in Maryland, the temperature around those roots can change much faster.
Combine that with shorter days, cooler nights, wind, and changing sunlight, and container-grown plants may begin showing dormancy earlier or more noticeably than similar plants growing in a protected landscape.
Here at the nursery, we generally begin to notice these changes around mid-September. There isn't one exact date. Different plants respond differently, and weather plays a major role. A stretch of cool nights can move things along quickly, while a warm fall may delay the process. By late September and October, however, it's completely normal for many deciduous trees, shrubs, and perennials to look very different from the same plants photographed during May, June, or July.
That's seasonal biology, not poor plant quality.
Why Are the Leaves Turning Yellow, Red, or Bronze?
Yellow leaves are probably the most common concern we hear in the fall.
During the growing season, leaves contain large amounts of chlorophyll, the pigment responsible for their green color. As deciduous plants prepare for dormancy, they begin breaking that chlorophyll down. As the green disappears, other pigments already present in the leaf become visible. That's why a green summer leaf may suddenly become yellow. The plant isn't necessarily overwatered, deficient in fertilizer, or unhealthy. It may simply be fall.
Not every plant turns yellow. Some develop orange, red, burgundy, bronze, or purple foliage. Carotenoid pigments contribute many yellow and orange colors, while anthocyanins are responsible for many of the red and purple shades we see. Genetics, sunlight, temperature, and weather all influence how those colors develop, which is why two plants sitting beside each other can look completely different during dormancy.
You're not necessarily seeing damage. You're watching the plant's seasonal chemistry become visible.
Perennials Go Dormant Too
This is where customers are sometimes surprised.
We expect Maple Trees and Dogwoods to change color and lose their leaves, but when an Echinacea or Hosta starts turning yellow or brown, it's easy to assume something is wrong. Perennials go dormant, too. Echinacea, Hostas, Rudbeckia, Hardy Hibiscus, Peonies, Daylilies, ornamental grasses, and many other hardy perennials naturally change appearance as their growing season ends.
Leaves may yellow. Edges may turn red or purple. Stems may brown. Eventually, the entire top of many herbaceous perennials dies back. The plant hasn't disappeared. The important living portions are in the crown and root system below the soil.
That's why a dormant perennial isn't always pretty, and a perennial shipped in October may look nothing like its June photograph. An Echinacea may arrive with yellowing foliage and brown stems. A Hosta may be collapsing. A Hardy Hibiscus may have lost most of its leaves. An ornamental grass may be losing its summer color. None of that automatically indicates an unhealthy plant. You're simply receiving it during a different stage of its natural life cycle.
Evergreens Go Dormant Differently
Evergreens such as Arborvitae, Hollies, Boxwoods, and many conifers don't go dormant by dropping all their foliage. But their growth still slows dramatically, and some may develop subtle bronze, olive, or darker winter coloration.
Dormancy doesn't look the same on every plant. That's why understanding the normal seasonal behavior of the particular tree or shrub you purchased is so important. If you grow Boxwoods, our guide to why Boxwoods turn brown explains how to tell normal winter bronzing from a real problem.
Don't Compare a Fall Plant to a Spring Website Photo
This may be the single most important thing to remember when ordering plants online during the fall.
The photographs on plant pages show what those plants can look like during their ornamental season. A Hydrangea photographed in June may be covered in flowers and foliage. That doesn't mean a Hydrangea shipped in October should look the same. An Echinacea shipped after it has flowered won't be covered in fresh blooms. A deciduous tree shipped during dormancy may have few or no leaves. A perennial may already be dying completely back to the crown.
The website photo shows you what the plant will become. The plant arriving at your door shows you what that same plant looks like right now. Both can represent a perfectly healthy plant.
Look Beyond the Leaves
As fall progresses, deciduous trees and shrubs may arrive with only a few leaves remaining, or no leaves at all. The leaves that are left have been through an entire growing season of heat, sun, rain, wind, humidity, and insects, so some may have brown edges, small spots, holes, or yellowing. That doesn't automatically indicate a serious health problem. Remember what those leaves are preparing to do: they're going to fall off.
When I'm evaluating a dormant plant, I'm much more interested in the stems, buds, crown, and roots than the number or condition of the leaves still attached. Leaves are temporary. The roots are the future of the plant.
So change what you're looking at. Instead of asking whether every leaf is green, look at the stems and buds. Look at the crown of the perennial. Look at the root system and root ball.
On woody plants, you can gently scratch a tiny area of questionable bark with your fingernail. Green tissue underneath is a good indication that the stem is alive.
A dormant shrub with healthy stems, strong buds, and a well-developed root system may look unimpressive when you open the box, but that same plant can produce tremendous new growth in spring.
When It's Not Dormancy
Dormancy explains a lot of what you'll see in the fall, but not everything. These signs point to a real problem rather than a plant resting for winter:
- A soft, mushy, or black crown on a perennial, or one with a sour, rotten smell.
- Dark, slimy roots that pull apart easily. Healthy roots are firm and usually white to tan.
- Brown, dry tissue under the bark on every stem, all the way down to the base. A dead tip or two is common; a plant that scratches brown everywhere is not.
- An evergreen browning throughout. Some evergreens naturally shed a few older, interior needles in fall. Browning across the outer foliage is different.
- Physical damage, such as a snapped main stem or a broken-apart root ball.
If you're seeing any of these, don't wait until spring to find out. Keep the packaging, take clear photos of the whole plant, its stems or crown, and the root ball, and contact our customer service team. We'd much rather look at it with you now.
Dormancy Is What We Want
Think about it this way. Would we really want a hardy tree or shrub growing aggressively in Maryland in November?
No. Tender new growth produced too late in the season may not have enough time to harden before winter. Dormancy is the plant protecting itself. It's slowing growth, conserving resources, and preparing its living tissues for colder weather.
There's another side to this that's easy to overlook. A plant slowing down for the season isn't demanding as much water and energy as it did during active summer growth. It isn't trying to establish roots while simultaneously producing flowers, pushing new foliage, and surviving ninety-degree summer afternoons. Instead, it can begin settling into its new location during cooler conditions. That's one reason fall is such an excellent time for planting trees and shrubs, as well as hardy perennials.
Don't Wake It Up: How to Plant a Dormant Plant
If your plant arrives in the fall and is clearly entering dormancy, don't try to reverse the process.
Don't heavily fertilize it because the leaves are yellow. Don't move it somewhere unusually warm just to make it start growing again. And don't treat normal fall foliage color as though it were automatically a nutrient deficiency or disease. The plant knows what season it is. Let it go dormant.
A dormant or partially dormant plant can still be planted as long as your soil and weather conditions are appropriate. Plant at the proper depth, water thoroughly after planting, and mulch the root zone without piling mulch against the trunk, stems, or crown.
If your ground is already frozen or waterlogged when the plant arrives, keep it in its nursery pot until you can plant. In colder regions, an unheated garage or shed is the safest spot; otherwise, set the pot against the house out of the wind and mulch around it. Check the soil and water when it's dry, then plant once the ground can be worked.
And remember that dormant plants still need moisture. Newly planted trees, shrubs, and perennials shouldn't enter winter with a bone-dry root ball. Check the soil and water when necessary, while avoiding constantly saturated conditions. Dormant doesn't mean dead, and it doesn't mean the roots no longer need water.
What Happens Next Spring?
For many fall-planted trees, shrubs, and perennials, you may not see much happening above ground for the rest of the year. That's okay. The important work is happening elsewhere. The plant settles into the soil, roots can continue developing while soil temperatures remain favorable, and the plant prepares for the next growing season.
Then spring arrives. Soil temperatures increase. Days become longer. Buds swell. Perennial crowns begin producing new shoots. Trees and shrubs start leafing out. And suddenly that unimpressive-looking dormant plant begins to become the plant you originally ordered.
Quick Fall Plant Checklist: Is My Plant Healthy or Going Dormant?
If your plant arrives in the fall and doesn't look like the photo you saw online, don't panic. Look at the whole plant first.
Yellow, red, orange, purple, or bronze leaves? Normal. It's one of the most obvious signs of a plant preparing for dormancy.
Leaves falling off, or few leaves at all? Also normal for deciduous trees, shrubs, and perennials in fall.
Perennial turning brown or dying back to the soil? Normal. The living plant remains in the crown and roots.
Brown stems? Scratch a tiny section of bark. Green underneath means the stem is alive.
Healthy buds on the branches and a firm root ball? Great signs. Those buds hold next spring's growth.
A few brown edges, spots, or holes? Late-season wear on leaves that are about to fall anyway.
Soil feels dry? Water it. Dormant roots are still alive.
Tempted to fertilize or bring it indoors? Don't. Let a hardy plant follow its natural cycle.
Mushy crown, rotting roots, or brown under the bark everywhere? That's not dormancy. See When It's Not Dormancy and contact us with photos.
Still finding healthy stems, buds, crowns, or roots? Plant it, water it thoroughly, mulch the root zone, and let it rest.
The most important thing to remember is simple: don't judge a fall plant by its leaves alone. If the roots, crown, stems, and buds are healthy, the plant is usually doing exactly what we want it to do. It's getting ready for spring.
Woodie's Take
Every fall, we start seeing the same changes here at our Maryland nursery. Around the middle of September, some leaves begin turning yellow. Others become red, purple, or bronze. Perennials start looking tired. Deciduous shrubs begin losing foliage, and by October, some plants look dramatically different from the way they looked in June.
And every year, we start getting emails asking whether something is wrong.
I understand it.
You ordered a beautiful plant, and naturally, you want it to look beautiful when you open the box.
But one of the things I've learned after spending my life around plants is that healthy doesn't always mean pretty.
Sometimes healthy means a tree covered in spring flowers. Sometimes it means a perennial full of summer blooms. And sometimes healthy means a brown stem, strong buds, a healthy crown, a good root system, and absolutely no leaves because it's late fall.
Plants have seasons. They grow, flower, produce leaves, store energy, and then rest.
Here in Maryland, plants growing in nursery containers can begin showing signs of that rest period around mid-September. Cooler nights, shorter days, changing sunlight, and temperature shifts around container-grown roots all signal to the plant that another growing season is coming to an end.
So if your fall plant arrives with yellow leaves, red foliage, some bronzing, fewer leaves than you expected, or a perennial that's already dying back, don't immediately assume something is wrong.
Look beyond the leaves and remember what season you're planting in.
A plant going dormant isn't a plant that's giving up. It's a plant getting ready for next year.
Plant it properly, water it thoroughly, mulch the root zone, and let nature do what it has been doing for a very long time.
Let the plant rest.
Because when spring arrives, that's when you'll get to see what you really planted.
Fall Plant Arrivals: Your Questions, Answered
Is my plant dead or dormant?
Look past the leaves. On woody plants, gently scratch a tiny area of bark; green tissue underneath means the stem is alive. On perennials, check that the crown is firm rather than mushy. Firm roots and healthy buds are good signs. Brown, dry tissue under the bark on every stem, a soft or rotting crown, or dark, slimy roots point to a real problem rather than dormancy.
Why did my plant arrive with yellow leaves in the fall?
As deciduous plants prepare for dormancy, they break down chlorophyll, the pigment that makes leaves green. As the green disappears, yellow and orange pigments already in the leaf become visible. Yellow fall foliage doesn't necessarily mean the plant is overwatered, underfed, or unhealthy. It may simply be fall.
Why does my plant look different from the website photo?
Website photos show plants during their ornamental season, often in late spring or summer. A plant shipped in October may have fewer leaves, faded blooms, or perennial foliage dying back to the crown. The photo shows what the plant will become; the plant at your door shows what it looks like right now. Both can represent a perfectly healthy plant.
Should I fertilize a plant with yellow fall leaves?
No. Don't automatically fertilize a plant that's naturally entering dormancy. Yellow fall foliage doesn't necessarily indicate a nutrient deficiency, and pushing tender new growth late in the season can leave it vulnerable to winter damage.
Can I plant a dormant plant in the fall?
Yes, as long as your soil and weather conditions are appropriate. Plant at the proper depth, water thoroughly, and mulch the root zone without piling mulch against the trunk, stems, or crown. If the ground is frozen or waterlogged, keep the plant in its pot in a sheltered, unheated spot and plant once the ground can be worked.
Do dormant plants need water?
Yes. Dormant plants still have living roots, and newly planted trees, shrubs, and perennials shouldn't enter winter with a completely dry root ball. Check the soil and water when it's dry, while avoiding constantly saturated conditions.
