Protect Young Trees and Shrubs From Voles, Rabbits And Other Critters

Rabbits, chipmunks, and voles (field mice) need a home for the winter. They often choose to nestle up near newly planted trees and shrubs and gnaw  on their sweet sapwood, girdling the trunk and essentially killing the tree. Fruit-bearing plants often damaged by critters over their first 1-2 winters include: apple, pear, peach, redbud, blueberry, and cane fruits. Young […]

Eliminating Messy Fruits From Large Landscape Trees

Messy fruit from yard trees are dreaded by property owners as well as park and city employees. Some notorious culprits are sweetgums, sycamores (planetrees), oaks, mulberries, persimmons, and (female) ginkgoes.

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

Evaluating The Weeping Redbuds

  There  are so many fine redbuds (Cercis spp.) which are hardy in the Southern Appalachian region (USDA zones 6 and 7) and elsewhere.  Through research and breeding efforts at the JC Raulston Arboretum in Raleigh, NC, Southeast U.S. gardeners can grow several more cultivars of our native Eastern redbud (C. canadensis and subspecies texensis) and […]

Redbuds With Very Few Messy Seed Pods

A few years back my church pastor complained about the ugly load of seed pods covering the redbud branches (Cercis canadensis) on the property in the fall. My suggestion to avoid messy seed pods is to plant seedless redbud cultivars. A number of native redbud (C. canadensis) cultivars produce few to no seed pods. Let’s start with the cultivars ‘Ace of Hearts’ and sister seedling ‘Little […]

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 […]
