I live in Westminster, MD. When is the best time to plant trees, spring or fall?
Carroll County Maryland
Take a look at our web page for When to Plant Trees and Shrubs.
Late winter through mid spring are the best times to plant woody ornamentals. However, some trees seem to establish better in the spring - birches, dogwoods, European hornbeams, hawthorns, golden raintree, magnolias, oaks, poplars, sourwood, sweetgum, tulip tree, willows, black gum, and zelkova.
While broadleaf evergreens are best planted in the spring, some like mountain laurel, boxwood, and hollies can be planted in the early fall if they are watered deeply and regularly (if needed) and mulched. See more information https://extension.umd.edu/hgic/topics/planting-tree-or-shrub
