Two of the most destructive diseases that target evergreen trees are stated below. There are numerous diseases that invade fir trees and that are prevalent in Fort Worth and the DFW metroplex area.
Cause by the deadly fungal pathogen Diplodia, pine tip blight targets mature fir trees that have been stressed, damaged and weakened. It spreads swiftly in damp spring weather and can infest your entire outdoor grounds via wind and splashing rain. It's choice host trees include Austrian pine, noble fir, Douglas fir, and Ponderosa pine; however, all fir tree varieties that are common in Fort Worth neighborhoods are at risk of becoming infected. Symptoms begin manifesting at the lower part of the tree and move upward. Early indications are brown needles and excessive needle loss with multiple cankers and black specks on needles and pine cones developing as the disease progresses. Left untreated, pine tip blight will kill the tree. It is urgent to contact an experienced tree company immediately if you observe your evergreen tree is turning brown.
This highly-destructive fungal disease targets Leyland cypress and other popular fir tree varieties. Leyland cypress trees flourish throughout Fort Worth and are frequently planted to create private areas.
