Spray A Selective Weedkiller Concentrate Over The Whole Lawn

Weed of the Week #887 – Yellow Woodsorrel (Air Date 4/5/15)

If youve got a lot of Sorrel in your lawn along with other weeds, spot spraying is useless.

Instead, use a selective weedkiller concentrate. Again, Weedol Lawn Weedkiller Concentrate is the best choice.

This is designed to be diluted in water and sprayed over the lawn with a knapsack sprayer or watering can.

Make sure you read the instructions can dilute it accurately though. If you make the solution too weak, itll have no chance of killing Sorrel. On the other hand, you might be tempted to make a strong dose but if you do this, you risk killing the grass.

How To Kill Oxalis

Just because it’s a common weed doesn’t mean you have to put up with it.

A member of the wood sorrel family, oxalis is a weed commonly found in lawns. This weed can actually be confused with clover when it’s not in flower. Here’s how you tell them apart: Clover has rounded leaflets in sets of 3, whereas oxalis has heart-shaped leaflets in sets of 3.

There are two types of oxalis: common yellow woodsorrel , which has light green leaves, and creeping woodsorrel , which has reddish, hairy leaves and spreads by way of its creeping stems.

Herbicide Control In Winter Wheat

No field studies have been conducted in Ontario. Wood-sorrel is generally not considered a prominent weed in Ontario cereal crops. The majority of herbicides used in winter wheat are applied post-emergent. Chemical control is generally most effective in situations where soil-applied residual herbicides can be used . Therefore, effective control in soybean will minimize the potential for infestations in winter wheat.

A study conducted in Morocco found that clopyralid , bromoxynil , tribenuron-methyl , MCPA, 2,4-D and dichlorprop/2,4-D did not provide effective control of buttercup oxalis .

Natural Oxalis Weed Killer Techniques

According to Bob Vila, you can complete some oxalis weed killer strategies with a few everyday household items. Sprinkling cornmeal in your garden will help keep seeds from germinating, but make sure to try this only after your desired plants are established. Vinegar is a natural herbicide that can be applied with a spray bottle, pump sprayer or brush, but make sure to keep it away from plants you want to stay in your garden, as it cannot differentiate between weed and beloved perennial. Apply vinegar in the morning on a day with little-to-no wind, so you don’t contaminate other plants.

If you don’t have many plants, pick the weeds by hand or use a spade to dig them up before they flower or form seed. Make sure to remove all the portions of the plant, including its roots and rhizomes. You can do this easily when the soil is moist. Afterward, don’t put the plants in compost bins with seeds.

What a Creep!

Creeping Oxalis has small light green heart shaped leaves, very similar in appearance to clover.

How to fight back against Creeping Oxalis

Scientific name: Oxalis corniculata

Creeping Oxalis has small light green heart shaped leaves, very similar in appearance to clover. The flowers are small, about 3-4mm in diameter and bright yellow in colour containing five petals. Creeping Oxalis, as its name suggests, quickly runs along the surface of the soil and produces roots from the leaf as it goes and creeps under and through your lawn. When seed pods mature they dry out and explode, causing the seed to spread. It is a very invasive and nasty weed, so it is important to take action against it as soon as possible.

Treatment

Creeping Oxalis is difficult to remove as crowns break off leaving roots for re-growth. You can hand remove small plants or dig out sections where you need to if they arent particularly large. If there is a substantial spread of Creeping Oxalis through your lawn, you will get better results by spraying your lawn with a selective herbicide.

A selective herbicide such as Lawn Solutions Australia All Purpose Weed Control will help to eradicate these weeds in all lawn types including kikuyu and couch and are safe to use on most varieties of buffalo except the ST varieties.

Oxalis Prevention And Lawn Maintenance

Placing mulch around landscape beds will prevent oxalis seeds from germinating, as will limiting light to the plant’s seedbed. You can also keep oxalis to a minimum by maintaining a healthy lawn to create less space for it to grow. Make sure to test the soil to get accurate fertilizer and lime recommendations and combine these with mowing height and frequency requirements to keep your lawn thick.

According to Scotts, watering your lawn the right way is also critical. Deep and infrequent watering helps grass win the battle over weeds by encouraging more profound root growth. Watering too little or too frequently can cause shallow root growth, resulting in a thin lawn or bare spots. If you live in an area where rain is frequent, you don’t need sprinklers to achieve the 1 inch of water per week that most lawns need.

Oxalis is one name for members of the Oxalidaceae family, commonly called woodsorrel, sorrel or shamrock. These small herbaceous plants spread quickly, and resemble clover, but are more tender and lighter in color. There are several varieties native to Europe and the United States, including creeping woodsorrel and common yellow sorrel, along with other, more regional, varieties. They are often planted as attractive groundcover, and are not always easy to eradicate, as they form underground mats with bulbs and roots.

Killing oxalis is best done with targeted herbicides like Oxalis-X or Weed-B-Gon if these are unavailable, general herbicides like Roundup, Ally and Escort also work. Mix them according to the manufacturers instructions.

Add dish detergent to the herbicide for more stickiness and thorough application to the small plants. A few tablespoons of detergent for a gallon of herbicide mixture is enough.
