How to Keep Weeds From Growing on Lawn


We all dream of a beautiful lawn free of weeds, but this will take work and effort on your part. Weeds do not know that they are not wanted and will fight for growth as much as grass will, putting them at odds. With some planning and maintenance, a weed-free lawn is possible.

Step 1

Choose a high-quality grass seed for any replanting that is necessary throughout the year. Grass seeds with the words "Quick", "Mixture" or "Combination" in the name are lower quality and will not produce the lush lawn that is desired. These "quick" seeds often are littered with seedlings of various weeds that will grow along with the grass. Keeping any seeds introduced to the lawn the best quality will reduce the number of weeds present.

Step 2

Fertilize the lawn with a combination fertilizer. These are easily found in various brands at a local garden supply center. Choose a fertilizer that has a pre-emergence agent or weed control product mixed in. Fertilize the lawn on a regular schedule, treating it four to five times each year.

Step 3

Mow the lawn regularly. Choose a mower setting that is in the highest range for your lawn type. This is usually 2 inches for most grass. This higher grass setting will allow for better grown of the lawn, smothering out weeds and preventing sunlight from reaching the roots of weeds. The grass will outgrow the weeds. Bag all clippings when weeds are present in the yard to prevent the spread of seedlings and weed matter.

Step 4

Aerate the lawn every two years. This will loosen especially hard, compacted soil, which leads to crabgrass and chickweed.
