Springfield, MA sits in USDA Zone 5b–6a, where cool-season grasses dominate. Timing your seeding correctly makes the difference between a thick, healthy lawn and a patchy disappointment.
When to seed: Spring vs Fall
Fall is best — Mid-August through early October is ideal. Soil is warm, air is cool, and weeds are less competitive. Grass has time to establish strong roots before winter.
Spring is second best — April 15 to June 1 works, but you’ll compete with spring weeds and summer heat. If you missed fall, spring seeding is worth doing.
