That’s normal. Horticulturists refer to it as “exfoliating” bark. Sounds dermatological. The reason it happens is because bark is a dead tissue that can’t expand as a tree’s trunk grows ...
Maple bark disease, or maple bark stripper’s disease, is an uncommon condition caused by exposure to the spores of C. corticale. [5] The spores are hyper-allergenic and cause a hypersensitivity pneumonitis. [6] [7] The disease has been found among workers in the paper industry employed to debark, cut and chip maple logs. The symptoms include ...
Frost crack or Southwest canker [1] is a form of tree bark damage sometimes found on thin barked trees, visible as vertical fractures on the southerly facing surfaces of tree trunks. Frost crack is distinct from sun scald and sun crack and physically differs from normal rough-bark characteristics as seen in mature oaks , pines , poplars and ...
Common tree care practices are to prune out such bark-included forks at an early stage of the tree's development, to brace the two arising branches above such a junction so that they can not split apart (using a flexible brace) or to reduce the length of the smaller arising branch, so that it is subordinated to the larger branch. [14]
Linda Runyon, author of books on wilderness living, recounts her experience of the effect of cold on maple trees as follows: I was relaxing in front of a fire in the crispness of early morning when Crack! A sound like an explosion came from behind me in the woods. I scanned the trees and saw that a maple tree had "exploded".
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.
Bark. It is a small deciduous tree growing to 10–15 m (rarely to 20 m) tall with a trunk up to 70 cm diameter, though usually smaller and often with multiple trunks, and a spreading crown of long, slender branches.
The amount of light a tree receives on its southwest side is correlated with the amount of sun scald the tree endures. Reducing the amount of light the tree is exposed to by planting a shrub or bush strategically to shade the southwest side can be less effective than wrapping or painting, but can have better aesthetic qualities for landscaping.
