Storm damaged tree appraisal I'm going out on a limb here, but I'm guessing at least some of you had a tree or two affected by this past weekend's weather If you did have damage, determine whether its feasible to save the tree. If the bark has been split so the cambium is exposed or the main trunk split, the tree will probably not survive and should be removed. If there are so many broken limbs that the form of the tree is destroyed, replacement is the best option. Topping, where all the main branches are cut back so that there are only stubs left, is not recommended. Though new branches will arise from the stubs, they are not as firmly attached as the original branches and will likely break in subsequent storms. Also, the tree must use a lot of energy to grow new branches, leaving less to fight diseases and insect attacks. Often, the topped tree's life is shortened. Broken branches should be pruned back to the next larger branch or back to the trunk. If cutting back to the trunk, do not cut flush to the trunk, but make the cut at the collar area. The collar area is the transition area between the branch and the trunk. Cutting flush with the trunk will leave a much larger wound than cutting at the collar and will take longer to heal. Middle-aged or younger vigorous trees can have up to 1/3 of the crown removed and still make a surprisingly swift comeback. If you didn't see a lot of damage and want to get ahead of the next storm, start now by asking this question: Can you prune out problem branches? If you question yourself at all, by all means, hire a pro to do the job. If you're thinking 'no sweat', consider these guidelines from Extension Forester Charlie Barden: 1) if a branch is less than 2 inches wide, go ahead. If it's 2 to 4 inches thick, think twice. If it's more than 4 inches across, get experienced help or be very sure of what you're doing. 2) Pruning above ground is extremely dangerous without firm footing in a lift or a comfortable, secure anchor to the tree. Rather than trying to work from a ladder, hire a professional. 3) Never work near power lines. Call the electric company, which often have staff arborists. 4) If you can't find and review your chainsaw manual, seriously consider hiring someone else to do the work. Experience helps - a lot - and that includes the insights gained while operating a particular saw. Nonetheless, the great majority of chainsaw injuries each year happen to experienced operators, using familiar machines. Should you decide to go ahead on your own, make sure you follow recommended guidelines for pruning. Do so by checking out the U.S. Department of Agriculture's Forest Service "How to Prune Trees" manual on the Web at www.na.fs.fed.us/spfo/pubs/howtos/ht_prune/prun001.htm. You can also request "All About Pruning" (C-550) from your Extension Office or online at www.oznet.ksu.edu/library/hort2/c550.pdf. Date: 12/6/07
