According to the UGA publication "Pruning Ornamental Plants in the Landscape" by Extension Horticulturists Gary Wade and James Midcap,
"As a general rule, plants that flower before May should be pruned after they bloom, while those that flower after May are considered summer-flowering and can be pruned just prior to spring growth."The phrase "just prior to spring growth" means that the window of opportunity is going to be closing soon, for many of the summer-flowering shrubs.Wade and Midcap include not only instructions for how to prune woody ornamental plants, but also a useful list of shrubs and small trees to prune in late winter:
|Chaste Tree (Vitex)||Japanese Spirea|
|Floribunda roses||Rose-of-Sharon (Althea)|
|Frangrant Tea Olive||Sourwood|
|Grandiflora roses||Anthony Waterer Spirea|

Additional information about pruning crape myrtle, an especially well-loved landscape shrub, can be found in the UGA publication "Crape Myrtle Culture."
Hopefully, the publications linked above will provide some direction for the gardener's pent-up energies as he or she contemplates the coming of another beautiful spring.
