You know you have trees that have decay, now what?
Pruning is the easiest of answers. Effective pruning by a professional tree service is the best choice. You should aim to eliminate codominant leaders early in the tree's life as well as removing crossing, broken or diseased branches. This type of work should be left to a professional tree service, like Trees "R" Us, Inc. on Chicago's North Shore.
Another good choice of prevention is the placement of protective devices that reflect the harmful effects of winter sun will help to prevent further damage to the bark of sunscald-prone trees. The device should be white or beige in color, placed in such a way that it allows air to circulate around the trunk and can be easily removed in the spring. Thanksgiving to Easter is the best time to protect against further trunk damage from sunscald.
Some other things you can do when your trees have rot are make sure they are in the right location. Right plant, right place. The selection of new trees for a landscape has a bearing on preventing future decay, as well. Certain trees, such as cottonwood and silver maple, tend to decay rapidly once infected. Other species, including walnut, Osage orange and ginkgo are more lignified and decay slowly. To make good choices, consult your local tree service, like Trees "R" Us, Inc. on the North Shore area of Chicago. Proper spacing and proper planting procedures all directly affect the health of trees too. Getting things right from the start allow for a health root system, which is key in the tree's health.
Inexperienced mower operators can cause serious damage to the protective bark. This can occur acutely or chronically. Either way gives decay fungi the opportunity to invade the inner tree tissues. By starting the mulch application 3 inches away from the trunk and using a 2 to 3-inch depth, vigorous rooting is also likely to take place.
Above all, when it comes to decay prevention, do everything possible to protect the bark. A solid, uninterrupted bark layer is the first and best line of defense against the invasion of decay organisms.
Tree decay can be present in significant volume without any external symptoms or telltale signs. On the other hand, cracks, rot pockets (portions of the trunk where large limbs have been removed), lightning strikes and fruiting structures are good indicators of internal decay. In other words, don't rely upon superficial walk-by inspections to reveal rot in every tree. Sometimes you have to look more carefully.
Remember, decay is a disease that often takes years to develop and become noticeable, unlike diseases that damage tree foliage. For this reason, older neighborhoods and landscapes are likely candidates for infected trees. If you live in this type of neighborhood, and especially if your yard has mature trees, contact your local tree service, like Trees "R" Us, Inc., to inspect your trees for signs of decay and other problems.
