An unusual swelling on trunks of trees and occasionally on large branches are “burls”. They’re round, swollen-looking growths on tree trunks and large scaffold branches. Should or shouldn’t you be concerned? Burls are not uncommon and can be found on cherry, maple, oak, buckeye, ash, willow, locust and walnut in Eastern forests. Root burls may […]

Across the U.S. and Canada, city planners, landscape architects, and property owners now enjoy a wide selection of landscape trees to plant on city streets, along roadsides, and in yards and gardens. Over the past half century new and improved varieties (cultivars) are disease and pest resistant and exhibit better branching and architecture. We now know to avoid […]

Fruit avoidance is on the mind of many property owners when purchasing trees and shrubs for their yard. Many like crabapples, mulberries and Chinese (kousa) dogwoods produce fleshy or pulpy fruits that mess lawns, walkways and stain parked cars. Many, not all, are non-native and foraging birds and […]

Winter can be a cruel period for trees. Day-night temperatures may wildly fluctuate and drying winds tend to injure tender buds. Maples (Acer spp.), flowering dogwoods (Cornus florida), birches (Betula spp.), yellowwoods (Cladrastis kentukea), walnuts (Juglans spp.) and elms (Ulmus spp.) are “bleeders”. The sap pressure inside branches is highest during the winter months. If any […]
