What is dove's foot cranesbill?

A native plant, common to dunes and grasslands on dry sandy or calcareous soils, dove’s foot cranesbill is a member of the hardy geranium family that can prove a problem in lawns where its explosive seed pods release seeds over a wide area, quickly covering the whole lawn.

Appearance

Dove’s foot cranesbill grows is up to 35cm (14in) high. Its foliage is hairy, grey-green, and divided beyond halfway into 5-7 rounded lobes. Deep pink to white flowers with deeply notched petals are borne from April to September.

The problem

Dove’s foot cranesbill like other geraniums, has bursting seed pods that can hurl seeds for some distance. If the weed is allowed to flower it can cover the whole lawn especially poorly growing, dry lawns.

Control

Non chemical

In lawns: The best control strategy is to mow low and often (removing the clippings rather than letting them fly), along with regular lawn feeding as this weed thrives in poor soil. Regular mowing discourages seed set and any seeds that do form will be collected and removed from the lawn. Raking the lawn before mowing to lift the foliage and seed heads might also help. Bin the clippings rather than putting them on the compost heap.

There isn’t much in the way of vegetative spread by runners or roots, so hand weeding should also be effective if you have the patience to deal with this small plant.

Chemical control

In lawns: Apply two or three applications of weedkillers containing 2,4-D plus mecoprop-P or 2,4-D plus dicamba. Examples include Doff Lawn Spot Weeder, Westland Resolva Lawn Weedkiller or Scotts Lawn Builder Lawn Food Plus Weed Control (also contains fertiliser).

Treated clippings

Do not add the first lawn clippings after application of a lawn weedkiller to the compost heap. To avoid possible contamination of compost, do not collect the clippings at all but mow frequently and allow the short clippings to remain on the surface of the lawn. These will quickly disperse to leave an acceptable finish.

New lawns

Weedkillers often cause severe damage if applied to lawns within six months of sowing or turf-laying.
