The best time to plant grass in Vermont is spring and fall. This gives the seed time to germinate before the extreme heat or cold sets in. Choose late April through May or late August to early September.
Kentucky bluegrass is a popular grass in Vermont because it's very winter hardy and has a wide range of uses. Perennial ryegrass can germinate and emerge four to five days after seeding. Fine fescue grass can handle shade or drought. Consider a mix of Kentucky bluegrass, fine fescue and perennial ryegrass for the best-looking lawn.
Sow grass seed with a hand or mechanical spreader, depending on the size of the lawn you are planting. Use 4 lb. per 1,000 square feet, unless the seed bag has a different recommendation. It's best to make two passes over the area, applying half the seed in each direction.
