Lawn Grass

Growing a lush beautiful lawn from scratch is easier than you may think. When you grow a lawn from scratch you have better control over the types and blends of seed used. Some blends are specifically designed for this area. Your Greenhurst seed professional will help will help you decide on the right seed for your application. As with any new planting, pay close attention to your watering schedule and patterns as not to flood areas. Enjoy… soon you’ll be mowing.


Grass roots typically extend 6 to 8 inches below the soil surface. Good topsoil in decomposed organic matter to that depth provides an ideal site for a successful lawn. Till the soil, remove the rocks, and apply a starter fertilizer. Then rake and roll seed bed until it is smooth and firm.

When overseeding an existing lawn, be sure to rake out thatch and expose the soil. It is of primary importance that seeds have contact with the soil.


Using a fertilizer spreader, spread half the seed evenly over the entire seed bed walking in one direction. The spread the second half walking at right angles to your first path.

Rake Lightly

Germination is improved when seeds are covered with 1/8 to 1/4 inch of soil – no more. Raking lighting will provide the necessary cover. Take care not to redistribute the seed. Then roll soil to embed the seed.

Cover Seed

Cover the seed bed with a very thin layer of moisture-retaining top dressing to keep soil from drying out. Typically a fine soil-aid or garden compost is used for this process. This task can be accomplished in a variety of methods; shaking the dressing from a large shovel, swing spreading the dressing from a large shovel, etc. do not cover the seed bed so thoroughly that the sun cannot filter through the soil.


The top layer of soil must remain moist until the grass is well established. Water the seed bed thoroughly after sowing, spraying with a light mist until soil is moist. Spray mist as often as necessary to keep surface moist. If using an automatic sprinkler system, set the clock to come on briefly 5 to 7 minutes three times a day. Be careful as not to allow the water to puddle and wash your seed bed away. Keep off the lawn until it is established. Depending on the time of year and weather conditions, your lawn should be ready for the first mowing in three to six weeks.

Weeding & Patch Filling

As perfect as your seed bed may have been before planting, it still will have some weed seeds. Many of the weeds that appear with your new lawn are annuals, they will die out after repeated mowing. For the hardier weeds that such as dandelions, pull by hand for up to eight weeks; then you may choose to apply a weed and feed fertilizer. For areas that were washed out or didn’t take, simply reapply seed as necessary. Wash outs are generally a pattern formed by a sprinkler. If using automatic sprinklers adjust the pattern or flow to help correct the problem. Be careful not to dehydrate other areas when you adjust a sprinkler head.
