with a tree or shrubs' roots can cause these plants to decline or even
die. If a plant's root structure declines, the problem usually cannot
be corrected in time to save the tree or shrub. Root decline can occur
rapidly or over a period of weeks or months.
or shrubs' root system needs a good balance of air and water in the
soil. In order for healthy growth of the roots, there must be a good
exchange between the soil and the atmosphere above the ground. Excess
compaction or an overly wet soil causes poor oxygen exchange between
the roots. This limits their growth potential. Often, signs of leaf
wilt will draw conclusions of a lack of moisture and one will water
excessively. This only compounds the problem, reducing the supply of
soil oxygen for the roots. This can be corrected by knowing which
plants are susceptible to problems from wet or compacted soil. By
probing around the plant, it can be learned if the soil conditions are
affecting the plant's root growth. Looking for compacted or overly wet
soil in and around the trees and shrubs will go a long way in averting
this type of damage.
excess moisture is the problem, divert water away from the plant or
reduce watering. Reducing the moisture content in the soil, thus
increasing the oxygen in the soil may save the plant. If the plant is
severely damaged over a long period of time by these conditions, it may
not be possible to save the plant.
trees and shrubs in areas affected by shade decreases the ability of
the soil to dry out. Ensure the plant is suited for these shady, wet
conditions. Planting trees or shrubs at an improper depth restricts the
amount of oxygen the roots can utilize. Changes in landscape can also
affect root structure. Paving of new sidewalks can seriously affect the
plants roots and cause root decline.
