Overview
Witch hazel is the shrub that flowers when nothing else dares. Native to the woodlands of eastern North America, it unfurls its spidery yellow blooms from mid-October into December, often after the leaves have already dropped. The flowers carry a clean, sweet scent that drifts on cold air, and the shrub holds up to brutal winters down to -35°F (-37°C).
It grows as a large, multi-stemmed shrub or small tree, stretching 15 to 20 feet (4.5 to 6 m) in both height and spread with an open, vase-shaped frame. The fall foliage turns a warm yellow before it falls, and the bark and leaves are the source of the astringent witch hazel toner found in any medicine cabinet, distilled for use on the skin.
This is an easy, low-fuss plant once it settles in. It asks for acidic, steadily moist ground and a spot with decent light, and it shrugs off cold, clay soil, and deer. The only thing it won't forgive is drought, so a young plant needs watching through dry spells.
Care
The short version: full sun to part shade, in moist, acidic, rich soil that never dries out. Water through dry spells, especially while the plant is young, feed once in early spring, and give it plenty of room to reach its full spread.
Light
Witch hazel does best in full sun, where it flowers heaviest and the fall color burns brightest. It will take partial shade without complaint, though too little light thins the bloom and invites mildew on the leaves.
Water
Keep the soil consistently moist, since this is a plant with no tolerance for drought. Water every 5 to 10 days during dry spells, and watch a young shrub closely through its first summers until the roots reach deep enough to fend for themselves.
Soil
Plant in moist, acidic, organically rich ground that drains well. A pH of 5.0 to 6.0 suits it best, and unlike many shrubs it puts up with heavy clay, so a damp, stiff corner of the garden can work.
Temperature
Few shrubs are this cold-hardy. Witch hazel weathers winters from -35°F to 100°F (-37°C to 38°C), which is what lets it bloom safely in late fall while everything around it shuts down.
Humidity
Ordinary outdoor humidity is fine, so there's no number to chase. Air movement matters more than moisture in the air here, since still, crowded conditions are what let powdery mildew settle on the leaves.
Feeding
One feeding does it. Apply a balanced or acidic slow-release fertilizer in early spring, and let the plant take it from there through the season.
Pruning
You can mostly leave the shears in the shed. Prune only to shape the plant, and do it in early spring, keeping in mind that flowers form on old growth, so cutting too hard costs you next fall's bloom.
Repotting
Witch hazel is a landscape shrub that rarely needs repotting. If you do grow a young one in a container, move it up when roots start circling or pushing out the drainage holes or the top growth stalls despite good water and feeding.
Size & spacing
Give this shrub real room. It reaches 15 to 20 feet (4.5 to 6 m) tall and just as wide, so set it well clear of buildings and other plants to let its open, vase-shaped frame fill out.
When to plant
Witch hazel runs on its own calendar, blooming in late fall while the rest of the garden sleeps. Plant it in spring or fall so the roots can settle before the extremes of summer or deep winter, and look for the fragrant flowers from mid-October onward, often hanging on bare branches after the leaves let go.
Northern hemisphere
Southern hemisphere
Typical months for a temperate climate: start earlier in warm zones, later where spring frosts linger.
- Sow: Sow seed after warm then cold stratification; germination usually within a year.
- Plant: Spring or fall
- Harvest: Fragrant yellow flowers mid-October to December, often as or after leaves drop
Hardiness
USDA hardiness zones: 3–8
Temperature: down to -40°C
Troubleshooting
Witch hazel stays remarkably trouble-free, and almost everything that does turn up is cosmetic rather than serious. Most issues show on the leaves in late summer. Match what you see below, then decide whether it's worth acting on at all.
Dusty white film spreading across the leaves
This is powdery mildew, a fungus that settles in where the air sits still and the shade lingers. Thin out crowded stems so air can move through the plant, strip off the worst-hit leaves, and keep the hose off the foliage. The damage looks worse than it is and rarely sets a healthy shrub back.
Fix:
- Improve air circulation by thinning crowded stems
- Remove and dispose of heavily infected leaves
- Avoid overhead watering
Cone-shaped or spiny bumps on the leaves
Those odd swellings are the work of witchhazel gall aphids, which feed on the leaves and trigger the plant to wall them off in galls. The galls look strange but do no real harm, so the easiest path is to leave them alone. Pick off and destroy the worst leaves if the look bothers you.
Fix:
- Tolerate damage, which is largely cosmetic
- Remove and destroy heavily galled leaves if desired
Ragged, chewed holes across the foliage
Caterpillars and Japanese beetles account for most of the chewed leaves you'll find on witch hazel. When numbers are low, picking them off by hand is enough to keep them in check. An established shrub shrugs off this kind of feeding, so light damage is nothing to worry about.
Fix:
- Handpick beetles and caterpillars when populations are small
- Tolerate minor feeding, which rarely harms established plants
Toxicity
Good news for any household with animals: witch hazel is safe around pets, livestock, and people. The ASPCA does not list it as toxic, and the worst a curious nibble tends to cause is a brief, mild stomach upset. Its bark and leaves are even distilled into the familiar astringent skin toner, which is made for the skin rather than the stomach.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
Safe to have around cats. A nibble might bring on a little drooling or a brief tummy upset, nothing more.
Dogs None
No concern for dogs. The most a curious chew tends to cause is some mild, passing stomach upset.
Horses Safe
Horses can graze near it without trouble, since the plant carries no toxin known to harm them.
Rabbits Safe
Rabbits are fine around witch hazel. A taste of the leaves does no harm beyond perhaps a soft stool.
Livestock Safe
Cattle, goats, and sheep can browse the foliage safely, as it holds nothing poisonous to them.
Birds Safe
No risk to birds, whether they pick at the seeds or perch in the branches.
People Safe
Safe for people too. The bark and leaves are distilled into the astringent skin toner, which is meant for use on the skin rather than eating.
No special handling required; ingestion of any plant material may cause mild, transient gastrointestinal upset.
Varieties
Most witch hazel sold for gardens is the straight species, but a few selections are worth seeking out for their size or their flower color. These are the ones you'll run across most.
Harvest Moon
A vase-shaped selection reaching 15 to 20 feet tall, hung with clear lemon-yellow flowers.
Little Suzie
A compact form that tops out at just 4 to 6 feet, carrying soft yellow flowers on a tidy frame.
Mohonk Red
A standout with reddish-toned flowers that break from the usual yellow witch hazel wears.
How to propagate
Witch hazel is slow and stubborn to propagate, which is why nursery plants cost what they do. None of the methods are quick, so pick the one that matches your patience.
SeedDemanding
Sow after warm then cold stratification · Up to or more than a year due to double dormancy
Growing witch hazel from seed tests your patience. The seed carries a double dormancy, so it needs roughly 60 to 90 days of warmth near 60°F (16°C) followed by another 90 to 120 days of cold near 40°F (4°C) before it will stir. Even then, germination usually takes up to a year.
LayeringModerate
Growing season · One or more seasons
Layering is the gentler route. Bend a low branch down during the growing season and pin it into the soil with trench or simple layering, and it will slowly put down roots of its own over a season or more before you sever it from the parent.
GraftingDemanding
Late summer · One or more seasons
Named cultivars are almost always T-grafted onto Hamamelis virginiana rootstock in late summer, and the union takes a season or more to knit. Nurseries lean on grafting because softwood cuttings are notoriously stubborn and seldom strike roots.
Myths
Witch hazel is named for witchcraft or magic.
The name has nothing to do with witches. It comes from the Old English word 'wych', meaning pliant or bendable, after the supple forked branches. Those branches were once cut as divining rods for dowsing water, and that 'witching' for water is where the folklore really begins.
