Weeds in your yard are a definite nuisance, and having stickers in your yard can be a pain, literally. Pre-emergent weed control and regular lawn care are the best forms of weed control, but there are circumstances that sometimes prevent this. Once you have stickers, also know as sandburs, they can be difficult to control, and will quickly spread across your lawn. But there are some steps you can take that will help kill stickers, as well as other grassy weeds in your yard.
Mow your lawn. Mowing your lawn prior to any post-emergent treatment will provide a greater success in killing the stickers in your yard than treating without mowing.
Pour the MSMA post-emergent weed killer into the multi-use hose end sprayer. Following the manufacturer's instructions, use only the amount of MSMA needed to treat your entire lawn. Set the hose end sprayer to a 1-ounce-to-1-gallon ratio for spraying your yard.
Attach the multi-use hose end sprayer to your garden hose. Spray your entire yard with MSMA post-emergent week killer, wetting your entire lawn thoroughly.
Repeat steps 1 through 3 at least 10 days after the first treatment, but not exceeding two weeks after this treatment. One treatment is not enough to control and kill any weed in your lawn, so make sure you treat a second time.
