Parsley piert is an annual weed that is common on waste land, pastures as well as lawns, especially on dry soils, lacking in nutrition.
It is sometimes called western lady’s mantle and parsley break-stone. A keen eye is needed to spot the weed, as it is very small and can be barely noticeable.
It can also survive low mowing heights, in many cases it is the cause of the turf being scalped by the mower height being set incorrectly.
It can also prove difficult to control with chemicals as it is resistant to many herbicides.
The small leaves are made up of three leaflets, which are deeply lobed, often looking like small fingers. They are often covered in soft hairs and are similar in appearance to those of doves-foot cranes bill, only smaller.
The tiny green stalk less flowers grow in clusters at the base of the leaves.
Parsley piert prefers dry, impoverished soils often lacking in nutrients.
- Removing individual plants can prove to be effective.
- Mow the lawn at a sensible height, avoid mowing the grass to short. This will scalp the lawn leaving it thin with bare areas, which is an open invitation for weeds, especially parsley piert.
- Maintain a healthy sward of grass with good lawn care practices to keep out the weeds.
Parsley piert is difficult to control with selective herbicides, as it is resistant to most products. In most cases more than one application will be required to control this weed.

Tips for successful weed control using selective herbicides
- Treat weeds when growth is strong, this is usually in May and June.
- Don’t mow the lawn 3 days prior and 3 days after the treatment, to allow for maximum uptake of the chemical.
- Spray when the leaf/foliage is dry, as this reduces runoff and allows the chemical to stick to the weed.
