How to prune veronica spicata subsp. incana

Deadhead after first flush (midsummer); cut back fully in autumn or early spring. Trim spent flower spikes back to a side shoot or the basal foliage to prompt reblooming. At season's end, cut all stems down near ground level. Divide congested clumps in early spring — this plant spreads slowly but benefits from periodic division to maintain dense, healthy foliage.

Deadhead as needed in summer; annual cutback; divide every 3–4 years. Veronica spicata subsp. incana (silver speedwell) benefits from deadheading to encourage a second flush of its violet spikes.
