How to prune spiked speedwell

Deadhead throughout flowering (early to late summer); cut back by half after first flush; cut to ground in late autumn. Snip off spent spikes to just above a healthy leaf or side shoot. After the main flush, shear the plant back by roughly half with clean secateurs. In autumn, cut all stems to ground level.

Deadhead regularly through summer; annual hard cut-back in autumn; divide every 3–4 years. Spiked speedwell benefits from deadheading spent flower spikes, which encourages re-bloom through summer. After the main flush, cut stems back by about half to promote fresh growth and prevent the plant from becoming lax and floppy. In late autumn, cut the whole clump to ground level. Divide congested clumps every 3–4 years.
