How Much Weed Killer Should I Use On My Lawn To Kill Crabgrass?

The amount of weed killer to use depends on the size of your yard. To determine how much to use, measure the width and length of your lawn in feet. Multiply these numbers together for a total number of square feet. 

Then divide that number by 100 to get an approximation of how many ounces you will need per 1,000 square feet. For example: 10 x 10 = 100 inches, so if you have 1,000 square feet (or 100 inches), then you would need 1 ounce per every 100 inches.

If you’re unsure what rate should be used on your lawn, start with the manufacturer’s recommended rate and work up from there if necessary. 

Be sure to wear protective clothing and eyewear while applying the weed killer; always read the label carefully first before using any herbicides or pesticides near children or pets.
