Soil:

Spike speedwell is easily grown in average, medium-moisture, well-drained soil. Rich organic matter can be added to the soil to improve overall performance.

Light:

This perennial grows best in full sun (> 6 hours sun) or part sun (4-6 hours sun), with improved flower performance in full sun.

Water:

Spike speedwell has fairly average water needs. The best performance occurs with consistent, regular moisture and sharp soil drainage (particularly in winter).

Fertilizing:

Feed your spike speedwell plants with a general-purpose slow-release fertilizer before new growth begins in spring.

Winterizing:

Cut back to basal growth in late autumn.

Maintenance & Pruning:

Removing faded blooms encourages the flower spires to rebloom. Cutting back faded spikes to the new growth at their base improves their appearance.
