•Keepyourtoolscleanandsharp,sothatyoucanmakesmoothcuts.Thesewillhealfasterandthejobwillgomuchquicker.Haveasharpeningstoneonhand.
•Sterilizetoolsaftercuttingdiseasedwood.(SeeDisinfectingPruningTools,page273.)
•Pruneeveryyear.Atreesuffersfarlessstressifyoupruneitmoderatelyeveryyearinsteadofcuttingoffalotofwoodeveryfewyears.
•Becarefulwhenworkingintalltrees.Useasturdyladder,wellsupported,andaskanotherpersontohelpsteadyit.Ifbranchesaretoohigh,astheymaybeonstandardtreesandnuttrees,payanarboristratherthanriskpayingthehospitalifyoufall.
•Whenyouprune,don’tbutcherthetree,butdon’tbestingy,either.Justasinthinningthefruit,myScottishbloodkeptmefromdoingagoodjobatfirst.NowIhaveaveryeffectivemethod.Igooutoneday,cutoffallIdareto,andhaulofftheprunings.Ithenreturnthenextdayandcutoffmore—aboutasmuchasIcutthefirstday—andthatappearstobeaboutright.Usetheadagethatthetreeshouldbeopenenoughthatabirdcouldflythroughitwithouthittinganybranches.
