Armillaria root rot, also known as ‘honey fungus’ or ‘shoestring root rot’, is a group of decay fungi comprised of at least 11 species. It affects both landscape and natural habitat plants throughout the United States.
Ash leaf rust can be a significant problem in the Mid-Atlantic area and along the New England coast. Leaves, petioles and green twigs become infected during May and June. When the infection is severe, premature defoliation can occur.
Bagworms are destructive pests of shrubs and woody ornamentals that are native to North America. Their spindle-shaped protective bags made from silk, debris and foliage provide camouflage, so they go unnoticed until there is significant plant damage.
