|Pinus resinosa is a large evergreen conifer which can reach 50 to 80 feet in height, spread varies, medium fast growth. Needles are in twos, 5 to 6 inches long, yellow-green.
Young trees have a short trunk with a heavily branched crown; as they mature they develop a round to oval crown with tufted foliage that makes it easy to distinguish them from Jack Pines or White Pines. Young trees have an orane-red bark which matures into reddish-brown, roughly diamond-shaped, scaly plates. Extremely cold tolerant, can handle exposed conditions, gravelly or sandy, acid soils, will suffer from salt damage. Attractive tree for windbreak or harsh conditions. Native from Newfoundland to Manitoba, south to Pennsylvania.
Pines are one of the most diverse groups of evergreen conifers, over 90 species are distributed throughout the Northern Hemisphere.
Although most are large trees, they can take a low growing shrub form. Pines have been very important commercially, in timber production, as well as a variety of other manufactured products such as turpentine and rosin. They tend to be more tolerant of varying soil types and urban environments than either Picea or Abies. Pines tend to develop tap roots, so one should not attempt to transplant them from the wild. All species are grown from seed, with highly variable seed stratification requirements. They can be subject to many diseases, such as damping off, root rot, dieback, blister rust, canker, blight, scale, pine needle miner, pine weevil, bark beetles and pinewood nematode. Well situated plants should be relatively trouble free.
They suffer salt damage along highways and can get tip burn in areas of high sulfur dioxide or ozone. In general they do not require fertilization, which can cause overgrowth.
