Timothy is a perennial type of bunchgrass that grows particularly well in cool, moist areas. Because of this, it does best in the Northeastern and upper Midwestern regions of the United States. Timothy requires a firm seedbed that is free of weeds, so the best time to plant this grass is in August or September.
Remove the weeds from the seedbed. The least expensive way to do this is to pull them by hand. However, you can also clear the area by spraying it with an herbicide and waiting about two weeks. Rake up the dead weeds and dispose of them.
Loosen the top 2-3 inches of soil with a tiller, removing any rocks, roots and other foreign matter that could interfere with the grass' growth. Timothy has a fairly shallow root system, so the tilling doesn't need to be any deeper than that.
Allow the prepared seedbed to sit for 2-4 weeks before planting the timothy grass. The ground needs to firm up and absorb moisture for the seeds to take.
Spread the timothy grass seed in a single layer on the seed bed, either by hand or with a seeder. You will need eight to 10 pounds of seed per acre of land.
Use the flat back edge of the rake head to smooth the dirt over the seeds if seeding by hand. The seeds should be about 1/2 inch in the soil. This isn't necessary when using a seeder because most seeders are equipped with presses that do this job automatically.
Water the grass daily, keeping the soil moist, until it sprouts. Cool-season grasses such as timothy usually take about a moth to germinate.
