Planting & Growing
Southwestern White Pine will grow to be about 60 feet tall at maturity, with a spread of 25 feet. It has a low canopy with a typical clearance of 1 foot from the ground, and should not be planted underneath power lines. It grows at a slow rate, and under ideal conditions can be expected to live to a ripe old age of 100 years or more; think of this as a heritage tree for future generations!
This tree should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This species is native to parts of North America.
Please note: Our Plant Guide is all about plants that will work in the high desert. It is not, nor is it intended to be, a current list of plants in stock on hand at each location or at our farm. We purposely do not sell or ship plants via the internet. Plant questions and availability are best determined in-store.
