Ponderosa pine regenerates by seed, with cones maturing in a two-year cycle. The tree flowers from April to June of the first year, and cones mature and shed seeds in August and September of the second year. Seeds are relatively small (7,000 to 23,000 in one pound) and fall only about 100 feet from the parent tree.
Attracted by the pine's lush green needles and fresh fragrance, many gardeners are planting ponderosa pine trees in backyards and gardens. Most gardeners can consider planting these pine trees since they thrive in USDA hardiness zones 3 through 7.
Ponderosa pine grows best in full sun and deep, moist, well drained soil, but will adapt to a wide range of soil and growing conditions including alkaline, dry, low humidity, wind,and high elevation. It is highly drought tolerant once established. It is damaged by late frosts and is intolerant of shade.. . . . .364011236325!]0000000000000009783314146415!]
