Pre-emergent

Fertilizer window

Lawn region: North (cool-season). Timing only; always follow the product label.

  • Kentucky bluegrass (cool-season): Early fall: Around Labor Day (late August–September); Late fall: Late October–November, before the ground freezes; Late spring: Optional around Memorial Day. Avoid: Early-spring and midsummer feeding (pushes top growth, favors crabgrass).

90% (early: most years still freeze after this)Apr 23
50% (the "average" last frost)May 2
10% (cautious: only 1 year in 10 freezes later)May 14

Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).

Vegetable planting calendar for 04354

Dates count from your average last spring frost (May 2) and first fall frost (Oct 10). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
