Answer: Fall is not a good time to prune because it may stimulate new growth which will not have time to "harden" sufficiently before winter. In addition, you will be removing next year's flower buds from spring flowering plants such as azaleas. Azaleas are better pruned in early spring (if you don't mind losing some blooms) or right after they flower. Privet can be pruned any time from early spring to late summer as needed.
