This limited bibliography helps identify the pertinent literature which contain means of controlling tree root growth. It remains the responsibility of the tree owner and the resource consultant to create and use root growth control tools and techniques that are tree-literate and do not destroy the many goods and services which trees bring to people's lives over long periods of time.

In the following article you will find an explanation of the problems that arise from this incompatibility and how to overcome them to achieve healthy, attractive trees and turfgrass.

It is one of the most serious tree diseases in the eastern United States, killing thousands of oaks each year in forests, woodlots, and home landscapes.

The challenge before us is to reduce the loss of remaining elms and to choose suitable replacement trees for the ones we cannot save. No publisher mhowell 2021-05-29T11:50:27Z Link https://forestryindex.net/links/how-to-save-dutch-elm-diseased-trees-by-pruning Dutch elm disease (DED), caused by the fungus, Ceratocystis ulmi, is the most devastating shade tree disease in the United States. Healthy elms can become diseased by 1) elm bark beetles that carry the fungus from elm to elm, or 2) through root grafting with already infected trees. Along with wilt symptoms, streaking (sapwood discoloration), a characteristic internal symptom of the disease, progresses rapidly down from limbs inoculated by bark beetles (Allison 1978).

The first step in preventing or controlling these injuries is to identify their cause. Most damage is caused by disease, insects, birds, mammals, or weather.

Since the turn of the century, millions of dollars have been spent in efforts to control or eliminate gypsy moth populations and to retard natural and artificial spread. In the early decades of this century, outbreaks occurred only in New England; today defoliation by the gypsy moth is far more severe and widespread.

A healthy birch tree should be able to survive and thrive for 40-50 years. In many yards, however, it is not unusual for birch trees, especially the white-barked birches, to die well before reaching 20 years of age.

Several injection products are on the market, and various means of application are recommended. Each product and method has pros and cons. The "best" product depends on the individual tree its current condition, the objectives of the treatment, and the resources available.

Bottomland areas have been under water for many weeks. Landowners, homeowners, foresters, park managers, and others are concerned about the long-term effect of the flooding on the forests of the Midwest and the Great Plains. No publisher mhowell 2020-07-29T06:01:30Z Link https://forestryindex.net/links/fertilizing-trees-and-shrubs In urban or suburban neighborhoods, trees and shrubs often need fertilizing. Modern home- building methods create adverse growing conditions for plants. Often, good topsoil is completely removed and not replaced. Heavy machinery scrapes and compacts fertile soil, reducing its aeration and drainage. Plants are crowded by streets and sidewalks, and must compete with grass for nutrients. Proper fertilization is especially important to landscape plants in this type of environment.

These urban soils tend to be heavily compacted, poorly aerated, poorly drained, and low in organic matter. Even where soils have not been affected, fertilization may be needed as part of a maintenance program to increase plant vigor or to improve root or top growth.
