Norway maple, red maple and sugar maple are the species most commonly affected. The trouble often starts after insect-induced defoliation, which weakens the trees and makes them more susceptible to secondary pathogens. Early signs of decline include small or scorched foliage, and premature fall colors on some of a tree's branches.
Dead or decaying trees in your own yard can be a nuisance with shedding limbs, peeling bark and barren branches. It can be tempting to take care of the problem yourself with a chainsaw or an ax ...
The striped maple is a small deciduous tree growing to 5–10 meters (16–33 ft) tall, with a trunk up to 20 cm (8 in) in diameter. [3] The shape of the tree is broadly columnar, with a short, forked trunk that divides into arching branches which create an uneven, flat-topped crown. [citation needed]
Several trees normally have marcescent leaves such as oak (Quercus), [5] beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows . [6] All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. [7]
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
Acer saccharinum, commonly known as silver maple, [3] creek maple, silverleaf maple, [3] soft maple, large maple, [3] water maple, [3] swamp maple, [3] or white maple, [3] is a species of maple native to the eastern and central United States and southeastern Canada. [3] [4] It is one of the most common trees in the United States.
Many pine trees turn yellow this time of year because of normal “needle drop” on the inside branches
Acer nigrum, the black maple, is a species of maple closely related to A. saccharum (sugar maple), and treated by some authors as a subspecies of it, as Acer saccharum subsp. nigrum. [2] [3] Identification can be confusing due to the tendency of the two species to form hybrids. The simplest and most accurate method for distinguishing between ...
