Oxalis WeedHow to Get Rid of Oxalis BroadLeaf Weed 

We here at Solutions understand the plight of the lawn owner when it comes to weeds. Some weeds are manageable, but there are others that want to make you want to tear your hair out. One of those type of weeds is Oxalis, which has over 800 different species which go by various names like wood sorrel, false shamrocks and sourgrass. These things are found all over the place which means that they could be near you. Here we will go beneath the surface in understanding this plant and touch on ways to control this invasive plant.

Oxalis Background Information

Oxalis (Oxalis griffithii) can be an annual or perennial plant with heart-shaped leaflets found 3 per leaf which look similar in appearance to clovers. Their flowers have five petals, which are usually fused at the base, and ten stamens. The leaves fold down at night, and open in the day to harvest sunlight. The mature seed capsules open explosively when disturbed. The petal color varies from white to pink, red or yellow; The roots are often tuberous and succulent, and several species also reproduce vegetatively by production of bulbils, which detach to produce new plants.

Oxalis is a perpetual weedy groundcover, which spreads through interlocking rhizomes that are easy to separate. Each rhizome has the capacity to produce small bulbils. The seeds are prolific and are ejected when ready from little seed cases that look like similar to okra. Anywhere the stem touches the ground the plant can root with the potential of creating a large number of plants.It also forms a fleshy taproot and an extensive branching root system. Managing Oxalis weeds can be a quite a heavy task due its tough root system and the different methods the plant has to reproduce itself and persist.

It is interesting to note that oxalis has for long been an edible plant eaten by us humans and has a wide variety of uses in cuisine and medicine across different cultures salads and recipes. It has a tart flavor when eaten.

How to Eliminate Oxalis

To treat oxalis you need to be about as persistent as the weed itself when it comes both to caring for your lawn and maintaining it regularly and in the herbicide application. Oxalis thrives in dry, open areas but can also be emerge in moist, well-fed lawns. It will often invade lawns that are thin from insect, disease, or maintenance problems. Thus, maintaining a regular schedule of mowing, fertilizing, watering and limiting shade from sunlight can help your soil to be in tip-top shape and discourage oxalis and other weeds from setting up camp.

We recommend using a broadleaf weed killer to tackle oxalis. From our encounters and tests with oxalis, they are easily controlled with Triclopyr, 2 4-D Amine and a three way herbicide containing Dicamba. Take your pick of whatever herbicide you wish to choose but be sure to look to the instruction label for specific advice when it comes to application rates.

Tips and Recommendations

  • Before applying herbicide, make sure to mow your lawn first. This will cut down some of the grass that is in the way and also it will damage the oxalis and open them up a bit to soak in the herbicide treatment.

  • Use a hand-pump sprayer with a thin tip nozzle. Spraying a fine mist is best when applying herbicides to oxalis.

  • Oxalis flowers, seed pods, leaves and stems can be eaten so you can always eat your weed problem away. However, those with kidney stones or gout should avoid it, as oxalis contains oxalic acid.
