In fall, prune the stems all the way down to the rosette and clean up any dead foliage growing close to the ground. For deciduous salvia, you need to delay pruning in cold climates until the end of the winter. Many salvias with rosette growth or those that form clumps are herbaceous but not all. Deciduous herbaceous salvias like salvia elegans are best pruned in spring after flowering, while herbaceous salvias with woody stems benefit from intense late fall or early winter pruning.
