Posted by Hugh on January 28th, 2014
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 […]

Posted by Hugh on January 22nd, 2014
“Mower disease” is a totally preventable human malady caused by permitting lawn grasses and weeds from growing near the crown of trees and shrubs. The problem is commonly seen on large properties such as church grounds, cemeteries and public parks. Large gang mowing machines (with many reels) cut 95-98% of the turf area. Workers follow […]

Nativar is a new term coined by Dr. Allan Armitage, Professor Emeritus from the University of Georgia. It combines the words “native” and “cultivar”. Nativar refers to a cultivar of a native plant. It attempts to excite the horticultural marketplace about new cultivars of native perennial plants, such as blackeyed Susan (Rudbeckia spp.), purple coneflower […]

Posted by Hugh on January 17th, 2014
Upright European hornbeams (Carpinus betulus cvs.) are versatile small to medium-sized deciduous trees that fit most landscape settings. Depending on which cultivar you select, the tree stands with a narrow vertical profile. It grows 35-40 feet tall and 15-20 feet wide. It’s cookie cutter by design as a street tree or tall narrow hedge. Hornbeams […]

Arizona cypress (Cupressus glabra) is silvery blue needled medium-sized evergreen (USDA hardiness zones 6 to 9). This southwest U.S. native demands full sun and excels in droughty, infertile, and well-drained soils. Conversely, Arizona cypress does not tolerate shade, poor air circulation and flooded soil. Arizona cypress is mostly disease and pest free unless too crowded […]

Posted by Hugh on January 8th, 2014
Most tree lovers don’t plant U.S native shagbark hickory (Carya ovata) (USDA hardiness zones 4-8). Instead, they often inherit one when purchasing property. Shagbark hickory is notoriously difficult to transplant and grows very slowly in its early years. Like oaks (Quercus spp.) and beeches (Fagus spp.), hickories are long-lived, often standing tall in an open […]

Posted by Hugh on January 5th, 2014
Perhaps tree lovers can’t plant wonderful trees such as shagbark hickory (Carya ovata), American beech (Fagus grandifolia), or white oak (Quercus alba). They can purchase property with the tree(s) growing on them. Most nurseries do not grow these difficult species or guarantee their success after planting. But, all is not lost! Modern nurseries, backed by […]

If you grew up with a spruce or a fir Christmas tree, Leyland Cypress (x Cupressocyparis leylandii) could be a big change. This conifer species thrives in the southern U.S. (USDA hardiness zones 7-b to 9). Leyland is a good choice for a live cut or transplanted holiday tree as firs (Abies spp.) and spruces […]
