When is the best time to cut back and shape shrubs and rose bushes, prunning them. It is spring now but still cold. When things dry out and warm up when should I do this? Thanks, Janice

The answer to this really depends on what kind of shrubs and roses you have.

Hybrid tea roses and landscape shrub roses are pruned in spring when the buds begin to swell but before they begin to grow. Old fashioned, once blooming roses are pruned after they bloom.

Flowering shrubs are pruned at different times too, depending on whether they bloom on old wood or new wood. The white flowered spireas, forsythia, lilac, azaleas, and rhododendrons, for example, are pruned right after they bloom. If you prune these now you will be removing the flowering wood and flower buds for this spring.
