We get asked to "cut", "chop", "hack at" limbs all the time. This is NOT what you want. In order to properly prune your trees or ornamental shurbs I.S.A. or ANSI industry standards must always be followed to ensure the health and beauty of your plant material. Limbs should be cut back to good lateral grow or to the collar to ensure that the plant/tree can heal and grow properly. Please do not leave half cut, jagged or torn cuts in your landscape plant material you are just inviting the possibility of decay disease infestation or irregular growth. If you ever have concerns cantact a certified arborist to help you with the situation.
