Hemlock Wooly Adelgid

Hemlock wooly adelgid is a persistent pest of hemlocks. It is an imported pest from asia and thrives here because it has no natural predators to keep populations in check. The white cottony sacs are actually females surrounded by 100 – 300 eggs. Eggs hatch into a "crawler" stage. Crawlers move out and settle on other unoccupied parts of the tree. It is at this stage that adelgids catch rides on birds, wind and other creatures spreading to other hemlocks. ...CLICK HERE TO HEAR SHOW and READ THE ENTIRE ARTICLE

Winter Injury

Winter injury is common on evergreens usually when very cold weather follows a warm spell. Leaf dessication occurs when water loss from leaves cannot be replaced because it is frozen in the soil. I will not prune these plants until after I see what happens when new buds open and expand in the spring. The most common plants to be affected by winter dessication include: schip laurel, japanese holly, all hollies, rhododendrons, yews, aucuba, and many other broadleafed evergreens. We perform anti-dessicant sprays to protect evergreens from injury. The use of these products has been controversal, however new formulas have been created that last longer and are more rain tolerant. ...CLICK HERE TO HEAR SHOW and READ THE ENTIRE ARTICLE

Construction Damage to Trees

Construction projects are detrimental to trees. Heavy equipment or storing of supplies compresses or “compacts” soil in the critical root zone of trees. The critical root zone is a circular area around the tree thats radius is measured 12 inches for every 1 inch of trunk diameter measured at 4.5 ft above ground. ...CLICK HERE TO HEAR SHOW and READ THE ENTIRE ARTICLE
