Creeping Speedwell

Creeping speedwell (Veronica filformis) is one of four similar forms of veronica that occurs as weeds in lawns.

Problem Overview

Creeping speedwell (Veronica filformis) is one of four similar forms of veronica that occur as weeds in lawns. This is a perennial weed that has wide hairy kidney shaped leaf. The stems produce roots to enable them to creep along the ground which creates a very dense mat.

This mat suppresses the growth of the desirable turf species. The leaves are dark green and are lightly serrated or toothed. It produces small pale blue or almost white flowers on longish stalks. It is regarded as more difficult to control than the other varieties of speedwell.

Solutions

All turf types: Creeping Speedwell can be selectively controlled by applying the herbicides Triumph Gold or Victory Gold at a rate of 40mls per 100m2 of lawn. The best results are obtained if the herbicide Quantum is added to the mix at 2mls per 100m2 of lawn.

Repeat applications may be required in circumstances where there is a lot of mature creeping speedwell in the lawn.

These products are not able to be applied to either couchgrass ( Bermudagrass) or kikuyu lawns. For these lawn species some control may be achieved by applying herbicides that contain 2,4-D & dicamba. However, the speedwell will recover in the absence of repeat applications.
