How to Put Lawn Seeds Down on an Existing Lawn to Make it Fuller

Overview

When your lawn is less than stellar, but doesn't require complete renovation, the solution may be overseeding. Overseeding, the application of grass seeds to an existing lawn, can help solve patchy grass problems as well as improve lawns with an overabundance of weeds, according to University of Iowa Extension. While overseeding has several time-consuming steps, your finished lawn should look lusher, making the hard work worth the effort.

Step 1

Prepare the lawn by mowing the grass to a length of approximately 1 inch. Mow the lawn with the vertical lawn mower as well to aerate the soil down to a depth of approximately ½ inch. You may have to run the vertical mower over the lawn twice for its blades to make an adequate number of slices in the soil, UI Extension advises.

Step 2

Rake the dead grass from the lawn with the garden rake and discard it into the lawn and leaf bag or compost pile, if you have one.

Step 3

Fill the seed broadcaster with grass seed. Cover the lawn area with the grass seed by pushing the seed broadcaster over the entire lawn. Push the mower in only one direction, or push it both horizontally and vertically for a thicker seed application.

Step 4

Mow the lawn again with the vertical lawn mower to work the grass seeds into the soil thoroughly. Good seed-to-soil contact is critical to a successful reseeding, according to University of Illinois Extension.

Step 5

Set up the sprinkler to water the lawn evenly, or use the hose with the shower attachment to water the lawn manually. Saturate every seeded area thoroughly. Water the overseeded lawn one or two times each day for approximately two weeks. After the seeds germinate and you see them poking up through the mature grass, begin to decrease the watering frequency and amount gradually over another two weeks until you are only watering if the soil is exceedingly dry.

Step 6

Mow the grass with the standard lawn mower to keep the established grass approximately 1 1/2 to 2 1/2 inches long.
