The best time in cooler climates for lawn seeding is in the Spring (April 15th - May 15th) or Fall (before October 15th). Seed planted in the fall usually wards off weed growth. The correct soil temperature for seeding lawns in cooler climates is 60 to 75 degrees fahrenheit. It is best to plant warm season grasses in the Spring when the soil temperature is 75 - 85 degrees fahrenheit. Proper germination is dependent on soil temperatures. Following the time guidelines indicated above are important.
What combination of lawn seeding will work best in your climate? Is the grass going to grow in a sunny or shady area? What are the traffic patterns on your lawn? I live in the Mid-West. A Kentucky Bluegrass, Perenniel Ryegrass, Fall Fescue mix works best for me.
Bags of grass seed are based on the square footage of the area that needs to be seeded. Make sure you determine the square footage before you begin lawn seeding. Always buy more seed than you need. You do not want to run out of seed in the middle of your project. Note...grass seed has an expiration date. A bag of seed is only good for 10-12 months. After a year, the seed may lose it's ability to germinate.
Grass seed is sold as either a blend or a mixture. A blend is one species of grass with many varieties of the same species. A mixture contains more than one type of grass species. This is your best bet because it provides diversity in your lawn. One species may be good in the shade, one may be durable in high traffic areas and one may be able to better handle stress. The mixture gives you the best elements of all grass types.
When buying grass seed be sure to read the bag. Manufacturers are now required to indicate the percentage of fillers or weed seed that are contained in the mixture. You want to grow a beautiful lawn not a field of weeds. You don't want to have to apply a herbicide a few weeks after your new grass grows.
Germination times vary. Cool season grasses typically take 3 to 14 days to begin to germinate.
By following these simple steps you will grow a beautiful lawn. Seeding lawns has worked best for me over the years. I seed my own lawn. I have a large pine tree in my front yard that has grown to be taller than my house. I have even been successful in growing grass under this pine tree, a very shady area by lawn seeding.
