How to Use Liquid Weed & Feed

Overview

Gardeners seeking to maintain a healthy and vibrant lawn usually resort to some kind of weed and feed product to control weed growth and fertilize the grass. When you use a liquid product, the active ingredients seep down into the soil more quickly. Make sure you use liquid weed and feed safely and properly when you apply it to your lawn.

Step 1

Mow the lawn one or two days prior to applying the weed and feed.

Step 2

Wear protective clothing as you mix and apply the liquid weed and feed. Wear goggles over your eyes, rubber gloves, long pants, long sleeves and shoes covering your entire feet.

Step 3

Mix the liquid fertilizer with water in the sprayer according to package recommendations. A 2,500-square-foot area of fescue, Bermuda or Kentucky bluegrass generally requires 1 quart of diluted weed and feed. A 3,750-square-foot area of St. Augustine grass generally requires 1 quart of diluted weed and feed.

Step 4

Cover any surrounding areas with tarps to prevent overspray, if necessary. Remove plants in containers to protect them from overspray.

Step 5

Apply the weed and feed with the sprayer evenly over your lawn area. The weed and feed should reach every area of the lawn.

Step 6

Rinse and wash your rubber gloves before you remove them. Remove all clothing and launder it immediately and separately. Wash your hands well with soap and water.
