"     When is the best time to trim holly trees and bushes, yews, boxwoods and burning bushes? I trimmed my yews in late July, and the tops are brown looking. I want to trim my boxwoods, but is it too late before winter? Glen Bates Dear Glen, Pruning encourages new soft growth that is susceptible to frost damage, so hold off trimming your boxwoods till late spring if you plan to do hard pruning; light tip pruning can be done any time. I think your yews may have gotten sunburned in late July; prune out the damaged growth next spring. As a rule, if hard pruning is necessary to reshape or reduce the height of a shrub, evergreens -- including most hollies -- respond best in the spring; deciduous shrubs, such as burning bush, or winged euonymus (Euonymus alatus), are best treated during the dormant winter period. Flowering shrubs, such as forsythia, mock orange, deutzia and magnolias, are generally pruned right after bloom time. Delay the pruning of berry-bearing shrubs such as viburnums and some roses till after the berry display has finished. Late-blooming shrubs such as buddleias and caryopteris can be left through the winter and pruned in late spring after the new growth has begun. "^^<http://www.w3.org/2001/XMLSchema#string>
