Parsley Piert [Aphanes arvensis]

Introduction: Parsley Piert, with its scientific name Aphanes arvensis, is an annual weed that occasionally makes its appearance on lawns. While it might not be the most common menace for your turf, its sneaky nature allows it to exploit weak spots, especially in closely mown lawns.

Description: This weed can be identified by its tiny fan-shaped leaves, each bearing three deeply lobed or cut leaflets. The green flowers, though minute, can be spotted nestled at the base of the leaves. They bloom between April and October, providing a rather extended window of visibility.

One of the reasons Parsley Piert finds its way into certain lawns is its preference for particular soil types. It thrives in dry, alkaline, and nutrient-deficient soils, especially in areas where the ground is left bare.

Control Measures:

  1. Hand Weeding:
    • Due to its shallow rooting system, Parsley Piert is relatively easy to uproot manually. Hand weeding is effective, especially if the infestation isn’t widespread.
  2. Lawn Maintenance:
    • Mowing: One of the primary reasons for Parsley Piert’s appearance is close mowing. Ensure that you maintain a proper mowing height, avoiding cutting the grass too short.
    • Balanced Feeding: A nutrient-deficient lawn is a playground for weeds. Adopt a balanced feed program to ensure your lawn gets all the nutrients it needs.
    • Healthy Lawn: The best defense against any weed is a strong, healthy lawn. Regular lawn care practices, including watering, aerating, and feeding, can help maintain a dense grass cover, making it difficult for Parsley Piert and other weeds to invade.
  3. Chemical Control:
    • Parsley Piert presents a challenge when it comes to chemical control. It boasts a resistance to most common herbicides, meaning that repeated applications might be needed to achieve significant results.

Safety remains paramount when handling chemicals. Always be equipped with the recommended protective gear. Adherence to the manufacturer’s guidelines concerning health, safety, and application methods is essential to ensure effectiveness and safety.

Conclusion: Parsley Piert, though not a frequent intruder, can pose challenges to lawn owners. Recognizing its characteristics and following a robust control strategy can help ensure your lawn remains lush and free from this pesky invader.
