Prefers moist, well-drained soil enriched with organic matter. Adaptable to a range of soil types (loamy, sandy, or clay) as long as drainage is good. Avoid overly wet or waterlogged conditions, especially in winter, which can lead to root rot. Ideal soil pH: neutral to slightly acidic (6.0–7.0).
Keep soil evenly moist during the first growing season to help establish deep roots. Once established, Veronica is moderately drought-tolerant, but performs best with consistent moisture. Water deeply once or twice a week during dry spells; avoid frequent shallow watering.
In spring, apply a balanced, slow-release fertilizer (e.g., 10-10-10) or compost around the base of the plant. Avoid heavy nitrogen fertilizers, which promote leaf growth at the expense of blooms.
Deadhead spent flower spikes regularly to encourage continued blooming and maintain a tidy appearance. After the main flush of flowers, cut stems back by one-third to promote a possible rebloom in late summer or early fall. In late fall or early spring, cut the plant back to the ground to prepare for new growth. Divide clumps every 3–4 years in spring or fall to maintain vigor and prevent crowding.
