Weedy Wednesday - Creeping Oxalis

Published : 12/16/2020

Creeping Oxalis or Oxalis Corniculta as it is formally known is a highly invasive, hard to control weed. It can be identified by the three small heart shaped leaves on each stem and thick growth pattern. Creeping Oxalis is often mistaken for clovers due to their similar appearance, which is not ideal as quick identification and treatment is key with these weeds. As the name suggests the plant creeps along the ground rooting wherever its stem touches the ground. It can quickly overrun your turf and can be extremely difficult to remove.

The weed is found all over the world and thrives in temperate to tropical climates, it’s most commonly found in the south east of the Australia. Its annual life cycle sees most plant die off during the winter and re-emerge in early spring, but can be found year-round in other climates

Creeping Oxalis comes in two common forms, green and purple. Both are very small with leaves growing to be around 5mm in diameter. In spring and summer the weed grows tiny yellow flowers with 5 petals. These flowers release a seed pod in late summer, these seeds quickly spread throughout your lawn, being aided by movement of soil, watering, and mowing.

The nature of its growth makes it impossible to physically remove from your turf as any stem fragment left behind can re-establish the weed. Chemical treatment is the best way to rid your lawn of these weeds, but it can be difficult because of the weeds resilient nature.
