Parsley Piert [Aphanes arvensis]
Parsley piert is an annual lawn weed. Although it is not a common lawn weed, it can be troublesome where the lawn has suffered from close mowing, taking advantage of weak and bare areas in the turf.
Parsley piert has tiny fan shaped leaves, with each leaf having three leaflets which are deeply cut or lobed.
The minute green flowers, which form at the base of the leaves are visible between April and October.
Parsley piert prefers dry, alkaline, nutrient deficient soils where the ground is exposed.
Parsley piert can be hand weeded as it is a shallow rooting plant and is easily removed. Encourage a lawn with good grass cover to prevent this and other weeds invading.
Pay particular attention the mowing height (don't mow to low) and keep the lawn fed properly with a balanced feed program.
Encourage a strong, healthy lawn with good lawn care practices to help maintain good grass coverage and prevent greater plantain and other weeds from invading.
Parsley piert can be a difficult weed to remove with chemicals, as it is resistant to most products. In almost all cases repeat applications will be required for adequate control.
When using chemicals on the lawn or anywhere else in the garden always wear the correct protective equipment and clothing.
It is important to read the product label and follow the manufacturers health & safety recommendations and application guidelines.
