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.


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


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


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


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.
