Expert tips
The key tip
Veronica spicata loves dry, well-drained soil, especially in winter. Too much compost or stagnant water weakens it.
The common mistake
Watering regularly or improving the soil: most veronicas soften, become mushy and rot at the base in winter.
The pro's trick
Cut back hard to 5 cm in February before growth starts: this rejuvenates the plant and creates a compact form that flowers more abundantly.
Care
Light and exposure
Spike speedwell loves full sun and flowers all the better when it receives at least 6 hours of direct sunlight daily. A sunny exposure strengthens the density of the flower spikes and the overall vigor of the plant. It tolerates shade poorly, where flowering becomes sparse.
Watering and humidity
Once established, this perennial resists drought and needs little water. Water moderately at planting and during the first few weeks, then gradually reduce. During active growth (spring-summer), watering during heat waves is sufficient. Avoid excess moisture, which causes root rot.
Soil type and drainage
Spike speedwell prefers well-draining, light, and not overly rich soil. Poor or chalky soil suits it very well. Improve drainage in wet areas by adding sand or gravel at planting time. Overly fertile potting soil encourages soft stems at the expense of flowering.
Pruning and cleanup
Cut back the plant in late autumn or early spring, before growth resumes, cutting it down to 10-15 cm from the ground. Remove spent flowers throughout summer to extend and encourage flowering. Light pinching of young stems in spring promotes bushier growth.
Fertilization
A moderate application of balanced fertilizer in spring is more than enough. Avoid excess nitrogen, which softens stems and reduces flowering. On poor soil, light fertilizer once a month during growth is sufficient.
Diseases and pests
This perennial is generally robust and rarely affected by disease if drainage and light conditions are respected. Powdery mildew may appear in humid, confined atmospheres: ensure good air circulation. Occasionally watch for aphids in spring, though intervention is generally unnecessary.
Did you know?
Spike speedwell has borne the name Veronica since ancient times, when it was associated with healing properties. In the Middle Ages, it was used in folk traditions as a tonic plant. Its dense, colorful flower spikes have made it a favorite in perennial gardens since the 19th century in Central Europe, where it has remained a staple plant in natural mountain landscapes.
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.
