' TREE PLANTING GUIDE 9~,f, by \~ Dale L. Shaw and Marvin Strachan -~--^ Colorado State Forest Service r -~E s ~s 817'6 PREPARA77ON PLANNING ~ ~ Moat tree plantings in Colorado have little chance for sarviva] unless planting site preparation ie prac- tiosd. Bite preparation is done to catch and afore moisten, educe grass and weed competition, and prepare soil for planting. Type of preparation done depends primarily on soil feature. Medium to heavy soil can be summer followed the year before planting. Sites can be left rough over winter and dbked or harrowed before plantlng time. it ie especially important f4 Bummer fallow sod end alfalfa sites before planting trees. 8aady eoiL subject to wind erosion should not be summer followed. A desirable practice on these sites ie planting cover crops each se sorghum, grain, or eudan grace the summer before trees are to be put in the ground. Site irrigation during the summer before tree plant- ing will build s reservoir of soil moisture. Another desirable pracf3ce is to construct a snow fence to the windward ride of the Bite the fall before planting. This will Huss snow to drift over the site and provide additional moisture for young trcee. Perennial weeds such u Canada thistle and bindweed should be eradicated before trees are planted. In planning windbreaks, the fiat item to consider u location. Place the planting on the windward side of areas needing protection with inside rows no closer than 100 feet from area W be protected. Snow, when eocom- panied by wind, will pile up in driveways and around buildings if the planting is too close. Avoid planting tall- growing treeeunder utility lines. Where farm driveways end main roads join, avoid creating hazardous blind corners by planting no closer than 20 feet to the main road. Curve the wiadbreek when possible for ease of cultivation and a pleasing appearance. Plan the number and length of cows so proper numbers of trees and shrubs can be ordered. Determine species needed and spacing between each plant and spacing between rows. Row spacing should be 16.206ed. Distance between plants in the shrub row should bs 3-6 feet for hardwood species; if juniper u used for s shrub row, apace plants 5.7 feet apart. For interior rows, spas evergreens &12 feet apart end hardwoods 10.1 fed apart. Place the shrub row on the windward side of windbreaks. Next come two or more rows of evergreens and then deciduous trees. Where space ie limited, it is better to have two or three rows of evergreens rather then deciduous trees because evergreens form a far mon efficient wind and snow barrier. ~~y1e~yyi~~y,~~y~y~~ y~~~aA'~~y',~~} f---Shrubs ~' ile M 'gryy,~ 'Mr 7Yr 'Mry~Myt,My~ ~farmstpd~windbresJ ~ ~ ~ ~i ~Ye ~i ` ~ ~i +lir 'Nr ~Ir ~~~0~~~ ~~~~ ~~~O0~~~0~~ ''1I~FF ~ O O Ana ~~~DO t Evergreens ,t Deciduous tees t t a ~, ; ~, ~`~. i ,... .~. y' . . i~' .t }~ C
