There are a number of things to keep in mind when going to prune a tree or shrub. First, to prevent the spread of disease, especially blight, make sure to use clean, sterilized tools. It is also important that the tools be sharp --to avoid tearing plant tissue. The first cuts should remove dead or diseased plant material. In the case of disease, sterilize the blade between cuts and make cuts at least two inches below diseased material begins. In general, make the cut at or just above a bud that points in the direction of desired growth. The cut should be made at a 45 degree angle; the apex of which is opposite the bud. When pruning, especially if pruning to thin out dense growth (and allow sun to reach fruit and for greater air circulation), consider the natural shape of the tree. Shearing branches (for topiaries and hedges) encourages dense, surface level growth that is not necessarily healthy for plants not intended for that purpose. Prune dead and diseased material all year. Prune spring flowering plants after blooms have dropped. Plants setting blossoms in the summer usually do so on new growth, so prune these during the dormant season.
