Care
Watering
Speedwell is undemanding when it comes to water. Moderate watering is sufficient after planting to establish the roots. Once established, it thrives on natural rainfall and tolerates drought well. Avoid excess moisture, which could promote rot.
Light Exposure
Choose a spot in full sun or partial shade for optimal blooming. Speedwell adapts to various light conditions but flowers more abundantly in the sun. In very hot climates, light afternoon shade can be beneficial.
Pruning
No strict pruning is necessary. Light removal of spent stems after flowering encourages better branching and extends the ornamental effect. In late autumn, you can remove dry stems at ground level.
Soil
Speedwell is undemanding and tolerates poor, stony soils. Well-drained soil is preferable to avoid waterlogging. No organic matter is needed; this plant even appreciates poor, challenging soils.
Fertilizer
No fertilizer is essential for this hardy, undemanding plant. Naturally fertile soil is more than sufficient. Too many nutrients could promote foliage at the expense of flowers.
Diseases and Pests
Speedwell is a very resistant plant, rarely affected by serious diseases. Powdery mildew may occasionally appear in cases of excessive moisture or poor air circulation. Ensure good air circulation and avoid wetting the foliage when watering to prevent fungal problems.
Did you know?
In the Middle Ages, speedwell was considered a plant of the pathways with healing properties, hence its Latin name 'arvensis' (of the fields). It grows easily on slopes and wasteland, making it an excellent pioneer for colonizing abandoned or disturbed areas.
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.
