How to Forage and Use Dogwood Bark in the Mountains
Dogwood bark has a long mountain history. How to know flowering dogwood in winter, gather from fallen wood without harming a tree, and dry and store it.
My grandmother kept a coffee can of dogwood bark scrapings on the top shelf of the pantry, and she let nobody reach for it but herself. As a girl I took that as a rule about the can. It was really a rule about the tree, and it took me forty years to understand how right she was.
Flowering dogwood (Cornus florida) is the small tree that blooms white in the spring woods all through the southern mountains. In the quiet months, once the leaves are down and the red berries have gone to the birds, it is also the tree that most needs a gatherer to think before reaching for a knife. I am going to show you how to know it in winter, how to take bark without hurting a tree that is already in trouble, and how to dry what you take so it keeps.
First, the one rule I give about any wild plant: never gather or use something on the strength of a book, an app, or a single source. Confirm it against more than one reputable guide and with an experienced local, and when in doubt, leave it be.
A sharp pocketknife or a hand pruner you already own will do much of the same work, so the hori-hori is not strictly necessary for twigs. Where it earns its place is scraping and prying the thin bark off a dead limb without slipping. It is a digging knife first, which makes it a little clumsy for fine work.
Why I take bark only from what has fallen
Dogwood anthracnose, a fungal disease that reached the mountains in the 1980s, has killed a great many dogwoods in the cove and on the ridge. The ones you still see are survivors, and many are stressed. Peeling bark from a living tree can girdle it, meaning a ring cut all the way around, and a girdled tree dies. I will not do it, and I ask you not to.
What I take is bark from limbs that have already come down in an ice storm or a windfall, or from wood a landowner has pruned and given me leave to use. That is more than enough for a jar. Take a little, and leave the rest of the tree to its work.
Check the rules before you go. In a national park, plant collecting is not allowed, and national forests have their own permits and limits, so ask at the district office. On private land, ask the owner.
Know the tree in winter
Flowering dogwood is easy to know in January if you look at several things together. Opposite branching alone proves nothing, since maples, ash, and viburnums branch the same way.
The bark. On a mature tree it breaks into small, squarish blocks, like a dark alligator hide, with a neat, tight pattern.
The buds. Flower buds sit at the twig tips and look like small gray-green buttons or tiny onion domes. Leaf buds are narrower and pointed. Those buttons on a dogwood are the best winter sign I know.
The shape. A low, spreading, layered crown, rarely more than thirty feet, with branches that bend upward at the ends.
In fall, clusters of glossy red berries. They are not for eating. Leave them for the birds.
If the tree you are looking at has smoother bark, alternate branching, or no button buds, then it is something else and you should not gather from it.
Drying the bark
Scrape or peel thin strips from the fallen limb with the knife, working along the grain. Cut them to finger length and spread them in one layer on a screen or a baking sheet in a dry, airy spot out of the sun. A drying shed is ideal, a warm kitchen shelf works, and it takes a week or two. They are ready when they snap clean.
I pack them in pint jars and write the plant and the date on the lid. In my experience the jars matter more than anything else, because damp dried bark molds, and moldy bark goes straight to the compost pile. Store them in a cool cupboard, away from light. For the full routine on keeping what you dry, see how to store dried herbs so they last.
How it has been used
What follows is traditional-use information: how people in these mountains and in the Southeast have handled this bark, and what I saw in my own family. It is not medical advice, it doesn’t claim to treat anything, and I’m not giving you doses. Anyone who is pregnant, nursing, or on prescription medication should talk with someone qualified before using any herbal preparation.
The Cherokee knew the dogwood long before any settler did, and it appears in their documented plant uses. I would point you to Hamel and Chiltoskey’s Cherokee Plants and Their Uses for what is recorded, rather than guess at it here. I’m sharing what I learned. The Cherokee knew it first, and I credit them.
In the settler tradition I grew up in, the bark was kept for a bitter tea. My grandmother would break a few small pieces into a pot of water, bring it to a boil, turn it down, and let it simmer with the lid on for twenty to thirty minutes. Strained through cheesecloth, it is a dark, very bitter drink. Bitter is the honest word, and nobody sat down with a cup of it for pleasure.
History records that dogwood bark was reached for as a stand-in when quinine ran short in the Southern states during the War Between the States. I tell you that as history, not as a recommendation, and I would not use it that way. The old twigs also served as a chewing stick for the teeth, a plain country habit that needed no recipe.
If you want to see how another mountain bark is handled start to finish, I wrote up how to forage and use tulip poplar bark, and the fall root dig in how to forage and use yellow dock root.
Where the knowing comes in
Taking a few strips from a fallen limb is the easy part. Knowing a tree in every season, what is safe to take and what is not, and how to leave a place better than you found it is the longer study. That is what I put into Appalachian Medicinal Plants, which walks through the plants of these mountains, how to identify each one, and the traditions behind how they were used. It is the book I wish my grandmother had written down.
