Act Quickly Against Eastern Filbert Blight
European Hazelnut (Corylus avellana) is highly prized both for its edible nuts and as a landscape shrub/small tree. Unfortunately, it is susceptible to eastern filbert blight (EFB).

Korean Maple Substitute For Fullmoon Japanese Maple
At first sight Korean maple (Acer pseudosieboldianum), aka Korean fullmoon maple, is very similar in appearance to fullmoon Japanese maples (A. japonicum var. Acontifolium). If you live in a northern U.S. such as the upper Midwest, growing Japanese maples will likely become an unfulfilled wish. Korean maple is a hardier choice for northern locales (USDA hardiness zones 4-8). […]

The tree averages 50-60 feet in height and 25-35 […]
