When underneath a light overstory which casts 50% shade, its growth slows by half from full sun conditions. Publication of this series was in part funded by the, California Department of Forestry and Fire Protection. Don’t neglect water in the period of establishment when you are growing ponderosa pines. The most widespread parasite is dwarf mistletoe which causes branch and stem deformation. Ponderosa pines are large trees native to the Rocky Mountain region of North America. One reason ponderosa pine is able to grow on dry sites is its vigorous rooting system. Hardy and drought resistant, ponderosa pine (Pinus ponderosa) grows rapidly, and its roots dig deep into most types of soil. Fast growing – more than 12 inches a year; Ponderosa Pine grows best in sandy, well-drained soils, although it will grow well in any soil that is not constantly wet.

In denser stands, roots are generally as wide as the tree's crown. For that reason, they are often planted for erosion control. Young ponderosa pine seedlings are threatened by moisture stress. The west slope of the northern Sierra Nevada, which receives an average rainfall of 69 inches, may be the wettest area in its natural range supporting ponderosa pine in large numbers.Ponderosa pine grows on a wide variety of soils, including those of igneous, metamorphic, and sedimentary parent materials. An interesting fact about Ponderosa pines is the number of years to maturity. Needles are stiff and between 5 to 8 inches (13 to 20 cm.)

Because ponderosa pine needs less nitrogen and phosphorus to grow its needles, the tree can grow well in soils which are not fertile enough for other species. Fire resistance is also fostered by the species' characteristically open crown and tendency to self-prune limbs when mature, which reduces fuel ladders. Although seedlings are killed by fire, larger trees possess thick bark, which protects them from fire damage. Conifers. Mature trees have roots down to 6 feet in porous soils and may extend laterally 150 feet in open stands. Gardeners in hot, dry areas sometimes opt for ponderosa pine as a landscape ornamental due to its hardiness and natural resilience; however, it is relatively slow growing. Ponderosa pine care is easier if you plant the tree in a sunny location on loamy, well-drained soil. When you look into ponderosa pine facts, you find that these trees can live and thrive for up to 600 years. Growth Rate This tree grows at a medium rate, with height increases of 13–24" per year.

A typical cultivated ponderosa pine grows to around 60 feet tall with a branch spread of about 25 feet (7.6 m.). Approximately 200 insect species affect ponderosa pine from its cone stage to maturity. Cones are oval, 3 to 6 inches long and 2 to 4 inches in diameter, with outwardly curved spines that make them prickly to handle. Ponderosa pine regenerates by seed, with cones maturing in a two-year cycle. The largest recorded diameter was over 8 1/2 feet. Young seedlings can withstand higher temperatures than most associates including Douglas-fir, white fir, and sugar pine but are more easily damaged from frost (23° F) than other trees.

The ponderosa pine, also known as the yellow pine, is one of the most widely distributed tree species in the West, growing from southern Canada into Mexico, and from Nebraska and Oklahoma all the way to the Pacific Coast. California is second, after Oregon, in production of ponderosa pine lumber, milling more than a billion board feet a year. Our third fast growing pine tree is the western yellow pine which is also known as the ponderosa pine or pinus ponderosa. In the past, frequent low-intensity fires kept many pine forests open and park-like and helped to maintain ponderosa pine in areas where more shade-tolerant species would have predominated. Big game such as deer and elk use the forests for food and shelter as do many other wildlife species. Bark is dark brown and rough textured in young trees and orange-brown with distinctive large plates in mature trees. This text was largely summarized from an article originally by William W.
