Tree and Shrub Pruning
The benefits of tree and shrub pruning include improved tree health, function (clearance), aesthetics, and flowering. Types of pruning include thinning, cleaning, reduction, structure, pollarding, espalier, and topiary.
Timing is essential and can be plant specific. Shrubs that flower on new wood can be cut back hard in late winter or early spring. This is called rejuvenation pruning and improves flowering while controlling size. Plants that flower on 2 or 3 year old wood should be pruned more selectively to preserve flower buds and or fruit.
In general, shade trees can be pruned on 3-5 year cycles and they can be pruned year round while dormant season or winter is best.
