Creeping Oxalis or Oxalis Corniculata as its formally known, is often mistaken for clover, it has small light green heart shaped leaves. This weed typically comes up in the cooler months in Melbourne, however can occur all year round (weather dependant).
Oxalis grows from bulbs deep in your soil, therefore it can be quite challenging to eradicate. The flowers are small, about 3 – 4mm in diameter and bright yellow in colour, containing five petals. As the name suggests, creeping Oxalis quickly runs along the surface of the soil as it grows and creeps under and through your lawn.
Persistence is key with this tough weed.
How do I remove creeping Oxalis in my lawn?
Hand removal can be good if the plant is caught early enough, but often the bulb can be deep, up to 100mm in your soil. The most effective method of control would be an ongoing application of pre-emergent fertiliser such as Oxafert, along with spraying plants with a selective herbicide such as Bin-Die.
The Oxafert should reduce the re-occurrence of this weed, however it may take several Spring seasons to completely remove this from your yard, so staying on top of this weed is key to success.
Fortunately, with self-repairing lawns such as Sir Walter DNA Certified Buffalo, Tif Tuf, Sir Grange and Eureka Premium VG, with time, and some extra fertiliser, any bare patches caused from creeping Oxalis will self-repair resulting in a beautiful lawn.
