Homeowners often wonder about the value of their trees when removals appear necessary or when a tree has suffered damage at the hands of a contractor, neighbor, or storm.

Leyland cypress has become one of the most widely used plants in commercial and residential landscapes, and it is relatively pest-free. However, because of its relatively shallow root system, and because they are often planted too close together and in poorly drained soils, Leyland cypress is prone to root rot and several damaging canker diseases, especially during periods of prolonged drought.

Carpenter ants are common in log houses and other wooden structures. These insects are primarily a nuisance, and are not likely to cause serious damage quickly.

Bot canker is a serious pathogen of landscape and ornamental trees. This fungus is opportunistic and generally requires a weakened or damaged host.

Roots on the surface of the soil can cause all kinds of problems, but not necessarily for the tree.

When planting trees near our homes, we have to be aware of the serious and expensive consequences of tree roots growing under driveways and sidewalks.

These trees were genetically selected for their perfect “lollypop” shaped crown, but it is that shape that is responsible for a shortened life span. The limited life of these trees is a function of structural failure, not “natural causes.”

Unfortunately, neither Mother Nature nor the character of a tree can reduce the very real risks associated with leaning. It’s not that trees that lean are inherently bad; it’s just that gravity creates problems.

Healthy roots are the foundation for a long, beautiful relationship with your trees. A girdling root problem starts very early in a tree’s development and can cut short a plant’s life.

Generally, trees with structurally sound root systems do not fall, except during very high wind events. When trying to determine which trees have root systems that are prone to failure, answers hinge upon a number of factors.
