If needed, take time to dethatch and core aerate compacted lawns so air, moisture and seed can get to the soil. Pennington One Step Complete products combine premium seed with a stabilized-release fertilizer and wood mulch to simplify lawn repairs. Better seed yields better lawns. Always use grasses recommended for your regional climate and choose top-quality grass seed you can depend on.
Pennington Smart Seed products provide premium grass seed appropriate for sun, shade or high-traffic areas in lawns in northern or southern regions.
Three-in-one Pennington Lawn Booster combines superior Smart Seed varieties with premium-grade fertilizer and soil enhancer. Apply seed at label-recommended overseeding rates, using the lawn spreader that suits the job.
Use drop or broadcast spreaders for large lawns and handheld spreaders for smaller areas. For small spots, simply seed from your hand. Work when the air is calm, so seed distributes evenly. Starter fertilizer, such as Pennington Ultragreen Starter Fertilizer , delivers essential nutrients for new grass. Phosphorus supports vigorous root growth, while nitrogen fuels top growth and greening.
Some states and counties restrict phosphorus lawn fertilizers due to environmental concerns regarding runoff, but exceptions may be made for new seedings. Check with your local county extension agent about nutrient application restrictions. Newly overseeded lawns need consistent moisture.
Keep seed and soil moist with frequent, light waterings twice a day for the first four days; water more heavily every other day for the next five days; then water as needed to prevent wilting.
This encourages deep, healthy roots. Keep your newly revived lawn looking its best with a regular, comprehensive maintenance plan that includes diligent watering, best mowing practices and proactive overseeding.
A simple weekday lawn maintenance schedule can keep your lawn lush and your weekends free. For a simple, all-in-one approach to a thicker lawn, you can put your lawn on the fast track with Pennington Lawn Booster. This easy-to-use product simplifies overseeding to give your lawn the boost it needs. In just one application, your lawn will grow quicker, thicker and greener than ordinary grass—guaranteed.
Lime-enhanced, pure-bred Pennington Smart Seed, backed by years of breeding and research, adds beauty and sustainability. Once established, these water-conserving grasses require up to 30 percent less water than ordinary grasses. That's year after year, for the life of your lawn. In their natural growth cycle, grass plants form seed heads and re-seed themselves.
Regular mowing eliminates the seed head. Mimic Mother Nature by re-seeding in fall. Overseeding will introduce youthful vigor and genetic diversity in existing turf. The most vigorous plants survive and carry on the integrity of the stand.
Overseeding with improved varieties of grass seed will create better quality turf for the future. Next-generation turf-type tall fescues in Macho Mix are narrower in leaf texture, darker in color, denser growth habit, and superior disease resistance. Perennial ryegrass blended in Macho Mix gives the fastest germination in cold soils. The turf-type tall fescues in Macho Mix retain great color during the winter months and provide a year-round green lawn.
Estate Mix is a blend of elite bluegrass varieties with perennial ryegrass added for quick germination in cool soils. Estate Mix is an excellent choice for late-season lawn renovating and early spring overseeding. Grass seed establishes best in warm soil, which encourages germination, and cool air to encourage growth. In the north, cool-season grasses are best seeded in late-summer to early-fall, when grass is actively growing and daytime temperatures are consistently in the low- to midsF.
Spring is the second best time to overseed. Overseed warm-season grasses in late-August to mid-September when the existing lawn starts to lose its color. Use a cool-season grass variety to keep your lawn green throughout winter while warm-season grasses are dormant. When the summer heat and rain return, the cool-season grass variety will die as the warm-season grass comes out of dormancy. Overseeding warm-season grasses is done annually.
Although not essential, aeration is helpful in preparing to overseed lawns as well. It loosens soil and provides grass seed better soil contact. Before overseeding, mow as low as your mower will go. This also helps provide better soil contact for the seeds and allows more sunlight to reach the germinating seeds.
Use a slow-release nitrogen fertilizer, such as Milorganite, when overseeding. Mixing Milorganite with the seed not only makes nutrients available to the grass when it needs it, it also makes it easier to see where the tiny seeds have been broadcast. This counts as the fall fertilization. Allow grass to grow to its optimum mowing height, which varies by variety, before mowing it for the first time.
Wait until the grass is established before applying an herbicide. Exactly how long to wait varies by grass variety and growing conditions. Pre-emergent herbicides will prevent grass seed from germinating, as it does weed seeds.
