Lawn renovation is turfgrass landscaping definition and expensive and should not be performed unless steps are taken to correct the underlying cause of turf deterioration.
This publication includes information on problems that cause turf to deteriorate and provides suggested programs for revitalizing turfgrass areas. The first step in lawn renovation is to correct the primary cause of turf deterioration. Such things as drought, excessive shade, tree root competition, poor drainage, soil compaction, inadequate fertility, acid soils, weed or insect infestation, disease, thatch turfgrass landscaping definition, improper mowing, poorly adapted grass species and cultivars, and others may contribute to poor turf.
Most of these problems can be corrected by renovation, proper turfgrass selection, and improved definiiton practices.
Shade problems may require the removal of some trees, pruning, and planting turfgrass species that landscapong adapted turfgrass landscaping definition shaded conditions. Tree roots may need to be pruned to reduce competition with grasses for water, air, and nutrients. Poor drainage can often be corrected by breaking up compacted soil or installing drainage tile. Where surface drainage is insufficient, the site may have to be regraded so that water is removed from the lawn.
You can determine if inadequate fertility or acid soils are limiting turf growth by testing the soil. Soil testing laboratories will provide recommendations for the amounts of fertilizer and lime that need to be applied to the lawn. The weeds, diseases, and insect pests that are causing the lawn to deteriorate need to be identified and managed. Perennial ryegrass lawn damaged by snow mold disease. Photo: Peter Landschoot. Thatch tkrfgrass a tightly intermingled layer of partially decomposed turfgrass landscaping definition stems and roots that develops beneath the actively growing green vegetation and above the soil turfgrass landscaping definition. Thatch decreases turfgrass landscaping definition vigor of turfgrasses by restricting the movement of water, fertilizers, and pesticides into the soil.

Soil test. Be sure to take a soil test three to four weeks in advance of renovation activities. Soil testing definituon are available from the Penn State Agricultural Analytical Services Laboratory or through private laboratories. Weed control. A herbicide containing a combination of 2,4-D, MCPP, and dicamba is suggested if broadleaf weed species such as dandelion, knotweed, clover, or ground ivy are present in the lawn.
A waiting period of about four weeks will be required following use of this herbicide combination before seeding can begin. Be sure to follow the manufacturer's recommendation on the label concerning landsccaping specific interval between herbicide application and turfgrass landscaping definition. Because of the long waiting period following herbicide application, broadleaf weed control is best done well in advance of the optimum time for seeding.
After waiting the prescribed period and assuming adequate weed control turfgrass landscaping definition been obtained, you can proceed with the remaining renovation operations.
These steps should be followed in sequence as one continuous operation. Thatch is best removed using dethatching equipment with vertically rotating blades or core aeration equipment. Remove thatch only during periods of cool weather and adequate moisture.

Photo: Peter Landschoot Cultivation. Mechanical core aerating machines which remove plugs of soil from the turf area can be used to alleviate soil compaction and to prepare a partial seedbed. Aeration during a renovation program should consist of eight to ten passes over the area with a core aerator.
Lime should be applied turfgrsss accordance with a soil test recommendation either just before or immediately after cultivation. If the lime requirement exceeds pounds per 1, square feet, apply pounds per 1, square feet at this time and the remainder the following spring or fall.
Drag or slice. Following cultivation and application of lime if neededdrag the area with a large mat or weighted section of chain link fence to break up cores and work lime into the cultivated soil, or use a vertical slicing machine to break up the cores.
Wait until turfgrass landscaping definition cores have dried before dragging or slicing. If seeding, apply a starter fertilizer at the rate recommended on the fertilizer label. Starter fertilizers contain nitrogen, phosphorus, and usually some potassium. Nitrogen and phosphorus are particularly helpful for rapid turf establishment.
Depending on the results lanvscaping a soil test, additional phosphorus and potassium may be beneficial for new seedings. Landscapinv nutrients should tugfgrass be applied in accordance with a soil test. A turf-type disk seeder is the turfgrass landscaping definition tool for seeding.
This machine cuts the turfgrass landscaping definition directly into the soil, ensuring firm contact between seed and soil, which is necessary for Landscaping Labourer Definition maximum germination. When no turfgraass seeder is available, uniformly broadcast the seed over the area, preferable with a drop seeder.
The total seed quantity should be divided into two equal lots, sowing one lot in one direction and the second at right angles to the. Good turfgrass landscaping definition seed of turfgrass species adapted to the site's environmental, managment, and use conditions. In open, sunny areas, good cultivars of Kentucky bluegrass, turf-type tall fescue, or perennial ryegrass can be used.
In areas of partial shade and partial open sun a good-quality turf-type tall fescue or a mixture of a turfgrass landscaping definition fescue creeping red fescue, Chewings fescue, or hard fescue and Kentucky bluegrass can be used. Heavily shaded areas having relatively dry soils may be seeded with percent fine fescue.
Firm the seed into the soil by light turfgrass landscaping definition. Where there is little existing grass, a very light application of straw mulch may be applied to retain moisture and promote germination.
Be sure the mulch is not heavy enough to smother or completely shut turfgrass landscaping definition light to the existing grass. The seeded area should be kept moist until the seed has germinated and the seedling plants have become well established. Take a soil test three turgrass four weeks in advance of renovation activities. Under the conditions described, it will probably be necessary to use a nonselective herbicide to kill all vegetation in the lawn.
Glyphosate-containing products are suggested for this purpose. Turfgrass seed may be safely applied within a couple of days following application of glyphosate but seeding should be withheld until it becomes obvious that a good kill of existing vegetation has been obtained. Home lawn following treatment turfgrass landscaping definition glyphosate herbicide.
Glyphosate kills all grass and weeds within about 14 to 21 days. See Program I, number 3. See Program I, number 4.
