New Lawn Care

Seeded Lawns: 

Expectations

A seeded lawn takes at least one full year to fill in uniformly throughout your yard; and many times, two years are needed to develop a thick luxurious lawn.

In the first season, there may be a weed problem, even though quality topsoil was used. Weeds can be easily controlled using a proper fertilization and weed control program. We would be happy to provide you with this service for an additional cost.

Mowing

Newly seeded lawns (or areas that have been re-seeded) should be allowed to grow to 3 1/2 inches before the first mowing. At that time, it should be cut to 3 inches and the clippings should be picked up.

Subsequent mowings on new lawns, and regular mowing on established lawns, should be done often enough so that no more than 1/3 of the total height is removed at one time (1/3 of the grass blade). IF this practice is followed on established lawns, clippings can be left on the lawn. However, if the grass is over 4 inches high when mowing time arrives, pick up excess clippings, as these tend to smother and mat-down the lawn. Mowing before grass gets tall also keeps the grass texture finer. When mowing grass over 4 to 5 inches tall, the stalks will turn brown and feel stiff to walk on.

Mowing too short is a common cause of poor, unhealthy lawns. In the summer, mow at the top setting, or about 3 to 3 1/2 inches. In the Spring and fall, mow as short as 2 to 2 1/2 inches on a smooth lawn.

De-Thatching and Core Aeration

De-thatching of your lawn (mechanical removal of thatch) is usually not needed for 3 years after lawn’s installation.

 

Core Aeration of your lawn, (removal of soil plugs to allow better water penetration and soil-air exchange) is recommended as part of your annual lawn maintenance program, and can be done the first season after your new lawn’s installation.

Water

Once grass seed is sown, watch closely so you will be aware when it begins to germinate. (Approximately 1 to 10 days for rye grasses.) The most critical time is when the grass blades are so fine they are almost invisible. You must water, very lightly to prevent washing out, 2 to 3 times per day, if possible. Begin as soon as your seed has begun to germinate, and continue watering, as instructed above, for two weeks for rye grass and turf-type tall fescue lawns; three weeks for fine and hard fescue mixes; and four weeks for good blue grass establishment. Blue grasses germinate last, taking about three weeks. These continuous, light waterings will allow your fescues and blue grasses to begin their germination without washing the seed and soil away. After this germination period, water lightly, approximately every other day, until you have mowed four times.

Even after your new lawn is well on its way, watering should be continued, as it is essential for a healthy lawn with vigorous, deep root growth. Adequate watering should be part of your regular lawn maintenance program throughout the growing season. Adequate water can be defined as: enough water to maintain some moisture in the soil at a depth of 2 to 4 inches.

One inch of water per week (including rainfall and additional water) should be satisfactory under most conditions. During drought periods (two weeks or longer with little or no rainfall) additional watering should take place. More water than usual is also essential for sandy soils, gravelly soils, or full sun areas on south or west facing slopes. The time of day when you water is also important. Most authorities state that early morning or evening watering is best to promote deep root growth and vigorous turf. However, The Ohio Landscapers Association urges homeowners to avoid very late evening waterings, as they can lead to fungus problems. Watering in the evening , late evening, or afternoon should be done early enough to allow the grass blades to dry off before nightfall. On windless, humid days, when pattern interruption and rapid evaporation is not a worry (we conservationists do worry), it is best to thoroughly water in the hottest part of the day.

Fertilization

After your seeded lawn has germinated, be sure to apply a fertilizer treatment every 30 days to feed the newly germinated plants. After the fourth mowing, make your first application of fertilizer, which should be a 15-10-5 or 20-10-10 formulation, specifically for lawns, and apply at a rate of 1 pound of actual nitrogen per 1,000 square feet. * (See notation)

Greenkeepers is partnered with TruGreen to provide any and all fertilization needs you may have. Call our office for more information.

Weed Control

Most weeds you see in your new lawn will die after a few mowings, but there are a number of weeds which can be a problem and make a lawn unattractive. Although many require specific chemical treatment, some general rules can be followed:

After weeds have begun to emerge in the spring, apply a BROADLEAF HERBICIDE to all established turf areas, following the manufacturer’s directions. Do not allow herbicides to drift onto shrubs or neighbors’ plantings. Although the use of weed killers is not recommended on new lawns (mowed less than 6 times), some special herbicides for young turf can be safely used, if carefully applied.

Crabgrass can be eliminated with certain herbicides, some of which allow for germination of grass seed while the crabgrass is being prevented. *(See notation)

*Please note— newly seeded lawns are fragile and easily burned with chemicals and fertilizers. We strongly suggest you call Greenkeepers to take care of your new lawn’s chemical needs for at least the first year. Insect and fungus control are rarely needed in the first year of a new lawn.

Special Lawn Care for Shady Areas

For heavily shaded areas that get less than 3 to 4 hours of direct sunlight, or all day filtered sunlight, we would strongly suggest the installation of shade-tolerant groundcovers rather than installation of turf grass.

For seeded areas that do receive at least the minimal amount of sunlight, (3 to 4 hours of direct or all day filtered sunlight), there are four maintenance practices to be followed by the homeowner:

  1. Grasses in shaded areas should be kept cut approximately ½” higher than grasses grown in full sun. (Should be kept at 3 ½” tall.) This allows for greater grass blade surface to utilize the available light.
  2. Grasses in shaded areas are in constant competition with tree roots for water and fertilizer. Larger amounts of water, and fertilizer may be needed.
  3. To keep shade to a minimum, and to improve air circulation, selective pruning of shade trees is recommended.
  4. Fungicides to reduce powdery mildew, and grasses resistant to it, may be necessary.

Sodded Lawns:

Expectations

Sodding is an expensive method of establishing turf, but there are many situations where this method is preferred to seeding, such as on steep slopes, terraces, and places where grass seed cannot become well-established, or when immediate turf is desired. By sodding, usuable turf is obtained in 2 to 3 weeks, as opposed to seeding, which takes much longer.

Watering

The same watering instructions apply to a sod lawn as with a seed lawn. Please refer to the section on watering seeded lawns.

Fertilization

Fertilization will not be needed for the first 3 weeks after your sod lawn is installed because you contractor added a balanced fertilizer when preparing your soil. Be sure to choose a starter fertilizer when the time arises to begin fertilizing.

Diseases

Blue grass sodded lawns may be more susceptible to leaf-spot diseases than seeded lawns.
