How Drought Affects Our Landscape Trees*

Long term drought can be devastating on landscape and woodland trees. An environmentally stressed tree must expend additional energy to survive. Extremes of drought leads to decreases in trunk diameter and height growth, declining resistance to pests and diseases, less food production via photosynthesis, and in flower and fruit production. Symptoms of drought stress include wilted […]

New Redbuds With Striking Foliage Abound

  Over the past decade Eastern redbud (Cercis canadensis) has undergone a real facelift. This native spring flowering tree can no longer be solely identified by its green heart-shaped leaves.

Redbuds With Very Few Messy Seed Pods

Formerly A Tree… Now A Hat Rack

Tree topping continues! The concern about a large tree falling on the house, garage, autos or pedestrians sends out calls to cut the tree back. If the tree in photo does recover (grow), the new branches will be mostly weak suckers. After 2-3 years, the sucker growth will be susceptible to high winds and snow/ice storms […]

What Can Be Done About Phytophthora

Phytophthora disease (Phytophthora spp.) is the fatal cause of root rots, stem cankers and crown rots. Several hundred species of plants are susceptible, including redbuds, dogwoods, rhododendrons, camellias, white pines, firs, yews (Taxus spp.), and fruit trees. It thrives in warm moist saturated soils. Phytophthora may lie dormant in the soil for several years, waiting for a […]

Summer Leaf Drop From Trees

  It’s late summer in the Southern Appalachian region (USDA zones 6 and 7). Outdoor temperatures continue to hit 90°F almost daily, and weekly precipitation is low. Over the past 3-4 weeks leaves have been dropping prematurely from landscape trees. Tulip poplar (Liriodendron tulipifera), river birch (Betula nigra), willow (Salix spp.), sycamore (Platanus x acerifolia), […]
