Weed Feed

Liquid Weed & Feed will kill your weeds while fertilizing your lawn.

How to Apply Liquid Weed & Feed Fertilizer

Liquid Weed & Feed is manufactured by the pbi Gordon Corporation. It is an herbicide and fertilizer combined. That means while it is busy killing the weeds in your lawn, it also adds nutrients that will help your grass grow strong. Liquid Weed & Feed saves you from having to use two separate products on your lawn. Just be aware that this product is a concentrate, and must be mixed with water before it is used.

Wait for a day when there is little to no wind and no rain in the forecast. This will prevent the Liquid Weed & Feed from being swept into areas of your lawn where you did not intend for it to go.

Put on a pair of gloves and some old clothing. You may also want to wear a mask and goggles when using these chemicals.

Measure out your Liquid Weed & Feed, and pour it into your backpack sprayer.

Add the water to the backpack sprayer and mix the two ingredients together. You now have enough Weed & Feed to cover 5,000 sq. ft. of lawn.

Spray the herbicide/fertilizer across your lawn in a sweeping motion. You may want to start at the far end of your lawn and work your way back toward the front.

The Best Time to Weed & Feed the Lawn in Florida

Use a brand of weed and feed specific to your variety of Florida turf grass.

Florida turf grasses require a complete fertilization in March and again in September, according to the University of Florida.

Use a product specific to your grass variety, and apply at the recommended rate.

How Often Should You Weed & Feed a Lawn?

Combined weed and feed products are not always the best choice.

Up to Twice Per Year

Apply weed and feed to a damp yard once a year in the spring when you see weeds begin to grow. It may be applied another time during the same growing season if needed, according to The Scotts MiracleGro Co.'s website.

As Rarely as Possible

Weed and feed damages shrubs, flowers, trees and some grass species, according to a Louisiana State University Agricultural Center Research and Extension website article. Many herbicides work better in spray form as opposed to granular products. Weed and feed should not be applied to areas where both fertilization and weed control are not actually needed.

Bottom Line

Use weed and feed products on a lawn no more than two times per year. Avoid other plants and flowers during application, and apply in localized areas only as needed. Always read the product's label prior to application to ensure that the product is appropriate for your lawn type.

The Best Time to Apply Weed & Feed Fertilizer

For those wanting to use weed and feed fertilizer to kill unwanted weeds, the best time to apply it is spring and fall, when the temperatures are around 70 degrees and the weeds are still young.

Do I Weed & Feed or Plant Seed First?

Plant the lawn first since weed and feed can inhibit germination.

Apply weed and feed to an established lawn in late spring and again in early summer. Plant lawn seed in the fall season followed by weed and feed in the spring to prevent damage to the lawn seed during germination.

How to Use Liquid Weed & Feed

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

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.

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.

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

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

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.

The Best Time to Weed & Feed Your Yard in Georgia

The application time for weed and feed depends on the type of grass.

Can Weed & Feed Kill My Catalpa Tree?

Catalpa trees are especially susceptible to damage from two common herbicides used in weed and feed products--dicamba and phenonxy. Do not apply weed and feed on areas where catalpa tree roots are growing; tree roots often grow as far out from the tree as the tree is tall.
