How to Fix a Weedy Lawn


As you look out over your green lawn, you may see scattered yellow flowers from dandelions or clusters of white flowers from clover. These weeds can degrade your lawn's overall appearance. Controlling weeds is a challenge as there are always weed seeds blowing through the air ready to germinate in your lawn. With both pre-emergence herbicide and post-emergence herbicide you can keep a handle on weeds and enjoy a weed-free lawn.

Step 1

Connect the post-emergence weed sprayer bottle to the end of your garden hose.

Step 2

Turn the water on at the spigot, and turn the dial on at the bottle to begin spraying the herbicide.

Step 3

Spray the herbicide over your entire lawn until all the foliage is wet.

Step 4

Turn the dial on the spray bottle back to the "Off" position, and turn off the water. Unscrew the bottle from the garden hose, and store it for future use if there is still herbicide in the bottle.

Step 5

Apply pre-emergence herbicide the following spring when the soil temperature has not yet reached 55 degrees F. This is usually when the forsythia start blooming. Pre-emergence herbicide comes in granules; apply it with your broadcast spreader at the bag's indicated rate.

Tips and Warnings

  • Apply both of these products when the wind is calm or nearly calm. Wind can carry these herbicides to undesirable plants and garden beds. If a pre-emergence herbicide gets in your garden, you may have a hard time germinating garden seeds.
