Speedwell
(Veronica filiformis)

This perennial spreads by seeds and creeping stems. It is found in lawns and is spread by mowing. Small mauve coloured flowers are produced from April to June. Control

The main way to keep weeds under control is constant vigilance, never allowing the weed to flower or seed and mulching.

  • Maintain a healthy lawn – scarifying, aerating, feeding and top-dressing in autumn will help, apply lawn sand in spring

  • Remove weeds by hand as soon as you see them

  • Spray with a systemic weedkiller that is absorbed through the leaves of the plant, the active ingredient makes its way through the cells of the plant down to the root. It kills these first and then the foliage starts to die off. Treat in March before flowering

  • Use a nitrogen-rich fertiliser in spring
