Restoration your lawn is not nearly as labour intensive as removing all of your turf and starting over with new topsoil and sod. Restoration can be performed from spring through fall. You may see some improvement in a restored lawn during the first season, but it may need one or more growing seasons to see progress. Remove Thatch The first step in starting a lawn restoration is to remove any thatch build up ( the inability of grass clippings to decompose naturally). Because of thatch build up, water cannot percolate into the root zone and fertilizer is also unable penetrate.  Thatch is removed mechanically or by hand. Several passes are needed over the lawn in different directions to expose the soil between the grass blades. We remove the dead thatch after each series of passes. Leveling the Lawn After we have completed detaching your lawn, we check for high and low areas. High and low areas can be due to poor grading. Drought, uneven settling, or the decomposition of buried tree stumps, logs or roots. To fill low areas in the lawn, topsoil combined with compost is applied to the old lawn. To repair high areas, we cut back the sod and soil to level. Nutrients To have a healthy lawn, the soil should contain 2 to 5 percent organic material. Increasing the population of microbes can increase organic material in the lawn. Microbes live in the ground and digest grass clippings, dead grass roots and stems. (Topsoil / compost). But they also make their nutrients available to living grass plants. Topdressing of compost mixed with topsoil followed by aeration will eventually incorporate some organic matter into the soil without disrupting the lawn. A slow-release fertilizer is than applied. Over Seeding Seeding, we sow seed by hand and a spreader, while walking in a perpendicular direction. Sow extra seed on bare areas, lightly cover the seed, with a mixture of compost and topsoil; and then spread more seed on top. Care for Young Plants The most critical need is to apply water at least 3-4 times a day, assuming no rain. If the soil is allowed to dry out, the seedlings won’t germinate or will soon wither and die. Soak your lawn by assuming no rain, lightly sprinkle or mist the lawn, morning and afternoon. Be sure you have moistened the soil to a depth of one inch. Keep the over seeded lawn moist until the young grass plants are 2 inches tall by repeating a light watering every day after periods without rain. This will take 4 to 6 weeks. When the grass is 2-3 inches tall, resume normal watering patterns, and mowing. Sod-The other method of the lawn restoration is to remove mechanically the old sod, haul away, and add garden mix and fertilizer, than install new sod. You now have instant new lawn, just water!
