Tree Pruning to ANSI Standards Winter is an excellent time to prune dead and hazardous branches out of trees, according to tree care experts. It is easier to spot potential hazards such as cracks, defects and deadwood in leafless trees, and apply corrective pruning when necessary. Proper pruning is an art based on scientific principles of plant physiology. Proper pruning encourages growth, increases flower and fruit production, improves plant health and removes damaged limbs, all which give aesthetic appeal to a tree.
Pruning at the right time and in the right way is critical, since it is possible to kill a tree by neglect or over-pruning. Pruning at the wrong time can be damaging to tree tissues. The best time for tree health to prune would be in early spring following a carefully written pruning prescription.
How can a homeowner know if an arborist will prune a tree correctly? This standard recommends, and in some cases requires, that the use of certain tools, cutting techniques and pruning methods be followed, and sets the standard definitions for terms the arborist will use in your estimate.
Properly written work estimates for tree pruning should be written in accordance with ANSI A standards. In addition to the information given on the work estimate, ANSI A sets some guidelines for basic pruning practices that arborists should follow.
