Leave Your Leaves on the Ground, Denver!
Jay Judd from Davey's East Denver office says fallen leaves fertilize the ground, making for less cleanup and a better environment.
Spongy moth
Spongy moths are insects who can cause extreme defoliation to trees when in their caterpillar stage.
Ganoderma Butt Rot of Palms
This disease is caused by a fungus that attacks palms. Palm fronds wilt from the bottom turning from dark green to brown. Mushroom growths, called conks, are seen on the lower portion of the trunk.
Mediterranean Oak Borer
This ambrosia beetle infests branches of vulnerable oak trees, invading branches in tree canopies, spreads through the trunk and can ultimately cause death.
Vascular Wilt Diseases
Vascular wilt diseases are caused by different fungi that attack the vascular (water-conducting) system of trees. A tree responds by blocking its vascular system to contain the disease. In doing so, the water supply to the leaves is cut off.
Cankers
Cankers are caused by various species of fungi that infect wounded or stressed trees. The canker itself is the dead area on the bark that can be found on the trunk or branches.
Line Clearance
Davey’s services include everything from distribution and transmission right-of-way clearance to utility forestry consulting services and custom herbicide applications using manual, mechanical and/or chemical application methods.
Thyronectria Canker
Thryonectria canker is caused by a fungus called Thyronectria austroamericana. It infects honeylocust, especially those stressed from other factors. The fungus causes cankers, on branches and trunks.
Armyworms
Fall armyworm caterpillars eat the leaves and stems of turfgrasses, but typically do not destroy the crown of the plant. Early feeding damage can resemble drought stressed turf, but can quickly progress to complete browning of the entire stand when caterpillars are present in large numbers.
Ticks
Ticks are small, wingless, bloodsucking arthropods. They burrow their heads into their host and can change drastically in shape, color and size when they become engorged with blood. Ticks have extremely small mouths that usually go unnoticed when they bite.
