Let’s see how you should prune different salvia types:

Salvia elegans
Salvia elegans

These salvias (Salvia elegans, S. guaranitica, S. leucantha, S. waverley, S. ulignosa & S. patens), known for their softer stems, benefit the most from pruning in spring, right after flowering. Cut the stems down to the ground once or twice a year for a healthier appearance and more abundant blooms.

Pruning Herbaceous Salvias with Woody Stems

Salvia greggii
Salvia greggii

For shrubby salvias (Salvia greggii, S. chamaedryoides, S. coccinea, S. microphylla), prune back after flowering, avoiding cutting all the way. Trim to at least where the first set of foliage starts on the flower stem. You can do more intense pruning in late fall or early winter, with lighter ones in late spring and mid-summer.

Pruning Rosette Forming Herbaceous Salvias

Salvia nemorosa
Salvia nemorosa

These salvias (Salvia nemorosa, S. x superba, S. penstemonoides) form low rosettes plus they are evergreen. Prune in either fall or spring by cutting stems down to the rosette, cleaning up any dead foliage near the ground. Be aware of their densely growing leaves, ensuring the undergrowth isn’t smothered.
