Even though we have received rainfall in our area, we are still
experiencing effects of the extreme drought.
2011 continues to be the year we blame for our troubles, but the facts
are we have been experiencing droughts before then. 2011 was the trigger year that set all the
damage in motion. It is very important to continue watering through the fall
and winter months. The meteorologist
predict a wet fall and winter. However,
if we endure prolonged dry periods in the fall and winter, trees, shrubs, lawns, and perennials will need to
be watered periodically to prevent root damage that affects the health of the
entire plant. The result of long, dry
periods during fall and winter is injury or death to parts of plant root systems. Affected plants may appear perfectly normal
and resume growth in the spring using stored food energy. Plants may be weakened and all or parts may
die in late spring or summer when temperatures rise. Weakened plants also may be subject to insect
and disease problems.
Fall
is also the time fruit tree care is forgotten or neglected, but it’s a critical
time for controlling some of the peach and plum tree diseases to insure a good
crop next year. Applying a copper
fungicide now can stop or at least reduce three of the major diseases that attack
peach and plum trees in Wise County.
Those diseases are peach leaf curl, bacterial leaf spot and bacterial
canker. Timing of the fall spray is
critical for effective control and for avoiding tree damage. Unless applied correctly, copper, a metal, may
cause severe defoliation. Spraying
should be done when 70 percent of the leaves have fallen.
Another
problem many homeowners are experiencing this fall is in St. Augustine
grass. Brown patch is a chronic lawn
problem for many Wise County residents. This fungal disease is characterized by large,
circular, brown patches of grass. Since
it is a fungus, fungicides can be helpful.
Granular fungicides are easier to apply than liquid and they have longer
residual. Inspect your lawn, if the
blades pull away easily from the stem and have a gray, rotted appearance, which
is a sure symptom of the disease.
