For best results, calculate your turf seed needs by seed type and square feet. Otherwise, a general rule of thumb is 3 to 4 pounds of grass seed per 1,000 square feet for new grass and 1 to 2 pounds of grass seed per 1,000 square feet for overplanting. Most seed bags will recommend a range of 250 to 400 square feet per pound. Sowing a new lawn or repairing stains generally requires about twice as many seeds as overplanting an existing lawn.
Use the rate with the highest coverage for new grass and for filling in bare or damaged areas. Use the lowest rate when planting seeds in an existing lawn to thicken the lawn, minimize weeds, or convert them to another type of grass. In general, only 10 to 12 seeds are needed within each square inch of soil for grass varieties such as fescue (Festuca spp. Department of Agriculture Plant Hardiness Zones 4 to 8 and 3 to 9, respectively.
With good starting fertilizer and a moist soil structure, a proper seed application uses a spreader as you walk in one direction across the yard. After applying the seed in this direction, turn at an angle of 90 degrees and spread the seed again. This strategy makes the distribution of seeds uniform and easy to rake into the soil for proper contact. If you have a small area to sow, it is possible to spread the seeds by hand if you mix 4 parts of sawdust with 1 part of the seeds, since sawdust provides a means to spread the seeds evenly without grouping them in one area after dispersing them by hand.
Too much turf seed causes undue competition for resources such as electricity, water and nutrients, and turf seedlings struggle as a result. Too little seed leaves grass thin or bare. Always follow “best practice guidelines” for planting turf seeds, including site preparation and good contact between seed and soil, and follow recommended seeding rates for lush results. For spring sowing, it is absolutely essential that you continue to water the seed and germinated grass regularly throughout the rest of spring, summer and well into autumn.
Creating a lush, vibrant lawn requires commitment, but the rewards of a successful turf seed project are worth it for the time and resources you invest. Whether you're growing from scratch or looking to fix unhealthy areas, knowing how many grass seeds to use can make the difference between a lush, green lawn and an unhealthy one. Maximize your investment of time and money in your lawn by using the right amount of grass seeds, and you can avoid disappointment with the final result. To promote good germination and a healthy start, regardless of the type of grass seed you have planted, it is essential that you keep the planted area and young plants well watered until they are established.
A higher quality, fresh seed that hasn't passed its germination date, with fewer fillers and fewer weed seeds, may be more expensive, but you won't need to use as much as you would with a cheaper, lower quality seed. In general, as long as you pay attention to the instructions in your grass seed package and sow them at the right time and temperature, you don't necessarily have to worry about the climate in which you're growing them. This is when cold-season grasses, such as Kentucky bluegrass and tall festochae, reach their peak growth, and conditions improve rapid germination and establishment. For example, perennial rye germinates in as little as 3 to 5 days, festoes take more than 10 days, Kentucky bluegrass takes 2 to 3 weeks, and warm-season grasses, such as centipedes, Bermuda and Zoysia, can take longer than a month.
Knowing how much grass seed you need per square foot of land is arguably the most important factor in growing a thick, healthy lawn. To avoid these problems, it's important to understand and know what to do when it comes to planting new grass. In general, the measurements given for turf seeds per square foot in any grass seed breed only apply if you sow them during the intended season and with the correct humidity, soil, light and temperature conditions for the seed to germinate properly. Knowing the right dimensions will save you money by buying too many grass seeds, save wasted time and labor, and avoid disappointment from poor results.
When soil test results show that the pH of the turf is below the levels necessary for optimal lawn health, liming according to recommendations restores the proper pH balance, increases nutrient availability and helps maintain the grass. When the grass you're planting is relatively thick and healthy and you just want to introduce a new cultivar to it, you may need fewer seeds. . .
