If your lawn suffers from soil compaction, rampant weed problems, heavy thatch, or nutrient and organic matter deficiencies, you may want to remove your existing turf and replant your lawn. that's a big job, but like a new roof, your new lawn will last a long time with proper care.
There are four ways to replant a lawn: by applying seed, planting either sprigs or plugs, or laying sod.
Don't by your seed on impulse! Choosing the right grass for your yard can make the difference between having a low-maintenance, environmentally-friendly lawn and one that is susceptible to disease, pests, and weed invasion, and a lawn that requires a lot of upkeep.
The type of seed you choose for either a new or restored lawn should depend on several factors.
A lawn that is dense as brand new sod, year after year, will have few weeds. To get your lawn thick, overseed the lawn in the fall or spring once or twice the first year. Once the second year, and then make it a routine to reseed every 3 to 4 years even if the lawn is looking really good.
A good mulching lawnmower chops u the grass so fine that their are never any clumps left on top of the turf. Recycling clippings back into the lawn for an entire season provides the grass plants as much nitrogen as there is in an application of fertilizer.
Using quick release nitrogen fertilizers need to be applied three or four times a year in order to be effective. They are high in salts, this increased salinity burns turf roots and repels valuable earthworms and kill many of the beneficial soil microbes. Using slow release nitrogen fertilizer needs to be applied only once or twice a year and will not hurt the soil critters. One application in the fall is all that is usually required in most lawns.
Things to consider before you water your lawn are, when does the grass need to be watered? and how much do i need to water my lawn ?
When you walk over a lawn that is mowed tall, you will leave temporary footprints. If the footprints disappear with the grass popping back upright within a minute or two the grass has enough water. If the footprints last more then 3 or 4 minutes, the lawn needs to be watered. Lawns need 2 inches of water a week in the heat of the summer.
A lawn that is dense and mowed tall is likely to be inhabited by a healthy population of beneficial insects, including ants, spiders, and ground beetles, seldom has any problems from fleas, grubs,sod webworms, chinch bugs, or any other grass insect pest. Brand Spectrum insecticides kill all the good guys along with the bad guys. Usually left alone the good guys will eliminate the bad guys themselves in a dense lawn.
