Care
Watering
Keep the soil moderately moist during the growing season, especially in the first few months. Reduce watering in winter. Avoid excess water, which promotes root rot. Regular but measured watering is generally sufficient.
Light Exposure
Place your speedwell in full sun or partial shade. It handles bright exposure well and will flower more abundantly with plenty of light. Partial shade also works, especially in hot regions.
Soil Type
Prefer well-draining, light and slightly chalky soil. Speedwell tolerates poor and rocky ground without issue. Improve the structure with compost if your soil is very heavy or clayey.
Pruning and Cutting
Pinch back young plants to encourage branching. After flowering, remove faded stems to promote a second flush of blooms and maintain a compact shape. Light pruning in late winter makes the plant more vigorous in spring.
Feeding
Not demanding, it requires only a light application of balanced fertilizer in spring. In naturally rich soil, no fertilizer is necessary. Avoid excess nitrogen, which promotes foliage at the expense of flowers.
Pests and Diseases
Generally robust, speedwell can be affected by powdery mildew in excessively damp conditions. Ensure good air circulation and avoid wetting the foliage. Aphids are rare but possible: treat with a mild insecticide if needed.
Did you know?
Speedwell officinalis has long featured in traditional European pharmacopeia, where it was credited with tonic and digestive properties. Its Latin name 'Veronica' refers to the legend of Saint Veronica, though the botanical etymology remains debated among historians. This humble little meadow herb inspired folk remedies from the Middle Ages through the nineteenth century.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
