Bulletin #2570, Common Witchhazel
Native Trees and Shrubs for Maine Landscapes
Developed by Marjorie Peronto, associate Extension professor, University of Maine Cooperative Extension; and Reeser C. Manley, assistant professor of horticulture, University of Maine.
This series of publications is the result of a five-year research project that evaluated the adaptability of a variety of native trees and shrubs to the stresses of urban and residential landscapes in Maine.Non-native invasive plants pose a serious threat to Maine’s biodiversity. Plants such as Japanese barberry, shrubby honeysuckle, and Asiatic bittersweet, originally introduced for their ornamental features, have escaped from our landscapes, colonizing natural areas and displacing native plants and animals.
By landscaping with native plants, we can create vegetation corridors that link fragmented wild areas, providing food and shelter for the native wildlife that is an integral part of our ecosystem. Your landscape choices can have an impact on the environment that goes far beyond your property lines.
Form: a small tree or large shrub with an open crown of large, crooked, spreading branches
Size: 15 to 20 feet high and wide
- clusters of tiny, bright yellow flowers bloom with the golden fall foliage
- picturesque winter branching structure
In Maine, common witchhazel is often found growing beneath the shade of beech and birch trees, keeping company with beaked filbert (Corylus cornuta) and an occasional native honeysuckle (Lonicera canadensis), and surrounded by colonies of maple-leaf viburnum (Viburnum acerifolium). It frequents the drier sites, being intolerant of flooding.
Use it along the edge of the dry woods or at the back of the garden border, placed where the October flowers, yellow with long, spidery petals, will invite you to linger in the garden at a time of year when few other flowers beckon. Or plant a colony of witchhazel in the open woodland, where its golden autumn leaves blend with the similarly colored leaves of the filbert, all catching and holding the morning light.
Hardiness: USDA zone 5a
Soil requirements: prefers moist to well-drained, slightly acid soils
Light requirements: full sun to shade
urban heat islands—intolerant
Insect and disease problems: resistant
Only a few birds and mammals devour the seeds of witchhazel, with ruffed grouse and fox squirrels being the most frequent ones. White-tailed deer will browse the twigs and foliage.
Irrigation: During the establishment period, defined as one year after planting for each inch of trunk diameter at planting time, water your trees regularly during the growing season. Give the root zone of each tree 1 inch of water per week; in general, a tree’s root zone extends twice as wide as its canopy. After the establishment period, provide supplemental irrigation during periods of severe drought.
Fertilization: Landscape trees and shrubs should not be fertilized unless a soil test indicates a need. Correct soil pH, if necessary, by amending the backfill soil. No nitrogen fertilizer should be added at planting or during the first growing season.
