Two kinds of pinyon true pine are aboriginal to the westerly United States . undivided leaf pinyon ( Pinus monophylla ) grows in Utah , Nevada , California and Arizona and is hardy in U.S. Department of Agriculture plant hardiness zones 6 through 8 . Rocky Mountain pinyon ( Pinus edulis ) has a wider distribution along the Rocky Mountains from Wyoming to northern Mexico and grows in USDA zona 5 through 8 . pinyon are problematical , humiliated - maintenance trees , with both species needing similar care . They are drought tolerant once established .
Step 1
In nature , both metal money of pinyon occur ona wide varietyof dirt eccentric . Single leaf pine is distinctive on well - drained , shallow , low birth rate filth . Rocky Mountain pinyon produce on both shallow and deep soils of low fertility . In your landscape painting , almost any kind of filth is suited as long as there ’s good drain . Do n’t locate either specie where water roll up , but situate them on slope or on mounds where water system enfeeble away .
Watering Needs
irrigate the new planted pinyon immediately and thoroughly . During the first class it ’s in place , water it regularly , especially during summer months to lay down a good root system . A suggested watering communications protocol is about once a month in September through May and twice a calendar month from June through August . demonstrate tree necessitate little extra urine except during drought years , when pinon should invite a mysterious monthly watering in winter and other spring . Overwatering can cause root rot and perhaps even dying .
Step 2
LIght and Growth Rates
Both kinds of pinyons ask full sun to grow well . growing is slow , with trees capable of tote up about 12 inches a twelvemonth to their height . Do n’t attempt to bucket along tree ontogenesis by extra tearing and fertilizing , which can weaken or belt down the pinyons . When grown from source , either species of pinon take about 25 years to reach a sizing where they will start producing strobile . If you design to grow pinyon pines to reap their eatable come , plant more than one pine for hybrid - pollination .
Fertilizer Needs
With their sluggish ontogenesis rate , pinon do n’t call for much fertilizer . The University of Nevada Cooperative Extension view it unneeded to fertilize or irrigate established pinyon , except if they have been damage . Mary Irish , writing about pine in her book , Texas Getting Started Garden Guide , recommends inseminate young trees once in the spring , and not fertilizing mature plant . The Lady Bird Johnson Wildlflower Center suggests giving Rocky Mountain pinyon a fertilizer with a 3 - 1 - 2 N - P - K ratio fertilizer three times a year . Use a product such as 12 - 4 - 8 applied at the rate of about 3 tablespoons per 10 square foot . Scatter the fertiliser evenly around the dripline of the tree and water it in well .
Pruning and Pests
crushed - alimony pinyon need prune to shape the tree when it is young or to hit deadened or damage branches on sometime trees . Before pruning , clean the pruning tools with a fabric soaked in rubbing alcohol to prevent fan out disease . Generally loose of diseases and pests , the pinon can be infested by a character of little engraver beetle called the pinon ips beetle ( Ips confusus ) . It burrows beneath the bark of pinyons and can cause tree diagram death . Beetles normally do n’t occur in healthy Tree . To head off ips beetle plague , avoid damaging the tree and its root or take into account it to become drought - emphasize . If you prune landscaping plants , do n’t stack the pertly edit out subdivision near pinyon tree , since newly swerve woodwind instrument attracts the beetle as a breeding land site .
