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 […]

A snow/ ice storm is both a beautiful and horrific scene in a landscape. Costly tree/shrub breakage, downed power lines, and subsequent utility shutoffs may be staggering results. Don’t feel powerless! Prepare and take action. During the storm, do nothing / “hands off”. Working near an active electrical line is deadly. After the storm you should immediately […]

Posted by Hugh on October 31st, 2019
Through the fall and winter seasons, certain landscape and woodland trees retain their dead brown leaves on branches. Beech (Fagus spp.) and oak (Quercus spp.) are two common examples. Winter winds and precipitation will eventually force leaves to drop. Plant scientists term the retention of leaves as “marcescence”. There are many theories as to why […]

First of all, there is no perfect tree, either for a street or landscape planting. However, many excellent cultivars are now available at local nurseries and retail garden centers. Select one that matches your site requirements. Site factors include: amount of sunlight daily, soil type, soil pH (acidity or alkalinity), and soil drainage. What kind of […]

Posted by Hugh on May 20th, 2017
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 […]

Posted by Hugh on January 29th, 2016
Some tree species are dioecious, that is produce single sex flowers (either male and female). Male flowers produce pollen and no fruits. Female flowers bear seeds or fruits. You may purchase male clones to avoid picking up messy seed pods or capsules in the fall. If you are allergic to certain tree pollens, avoid […]

In recent years urban tree diversity has become a buzz topic. The threat of losing entire street plantings to a deadly exotic disease or pest has to often become the reality. Nearly a century ago, urban tree-lined thoroughfares were laid bare by losses of American elms (Ulmus americana) and […]

Almost any time is a good time to plant trees – weather permitting. Sort through many great choices and avoid planting weak wooded species. These six tree species are generally short-lived, messy, and insect and/or disease susceptible. A few may also be designated invasive in your state. […]
