🌱 Speedwell

Grow speedwell (Veronica spp., commonly cultivated forms) in fertile to moderately fertile, well-drained soil. Avoid heavy, waterlogged ground—improve with grit/sand and organic matter. Best growth is in neutral to slightly alkaline soils; in very acidic soils, incorporate garden lime if appropriate for your site. Space plants to promote airflow and reduce mildew risk.

Sow seed on the surface (or very lightly cover) of a fine, free-draining seed compost; light aids germination. For best results, sow in late winter–spring under cover at ~15–20°C, or autumn-sow outdoors for natural cold stratification (alternatively provide 4–6 weeks cold before warmth). Keep evenly moist but not waterlogged; germination is often in 2–4+ weeks. Prick out seedlings when large enough to handle, grow on, and plant out after frost risk has passed, hardening off first.

Speedwell generally needs only light feeding. Top-dress with compost in spring; if growth is weak, apply a balanced, slow-release fertilizer once in spring (avoid excess nitrogen, which encourages soft growth and fewer flowers). Deadhead and lightly shear after bloom to encourage repeat flowering without heavy fertilization.

Apply a 2–5 cm layer of compost or fine bark in spring to conserve moisture and suppress weeds, keeping mulch off the crown to prevent rot. In colder climates, add a light winter mulch after the ground begins to freeze to limit frost heave, removing or thinning in early spring.

Generally self-supporting; stake only taller cultivars or plants in exposed, windy sites to prevent lodging.

Commonly used as an herbal infusion of the dried aerial parts (leafy stems/flowering tops). Steep about 1–2 tsp dried herb per cup in hot water for ~5–10 minutes, then strain. Use as a mild, non-aromatic tea; discontinue if it causes stomach upset or allergic reaction.

Deadhead to prolong flowering; shear back stems after the main flush and cut down old growth in late autumn or early spring.
