Germander Speedwell [Veronica chamaedrys]

Germander Speedwell lawn weed

Description:
Germander Speedwell is a perennial weed but is less of a problem on well maintained lawns than Slender Speedwell. These Speedwells spread by both underground and over ground runners and can be found on most soil types, but favour damp moist conditions. The leaves are kidney shaped and have prominent veins with toothed edges. The flowers which are a blue/purple colour with a white center can be seen between April and June.

Control:
Hand weeding may be possible if there are a few plants in the lawn. Raking or slashing this weed will help weaken it. Adopting good lawn care practices promotes a thick sward which in turn discourages weeds. Once Germander Speedwell has become widespread a chemical weed killer will be needed, but bear in mind this is a difficult weed to control. Use a selective herbicide containing fluroxypyr, clopyralid & MCPA for the best results, mecoprop-p and dicamba may also have limited success in controlling this weed. A repeat application 6 weeks later will be necessary, even then success may be limited.
