90% (early: most years still freeze after this)Apr 23
50% (the "average" last frost)May 6
10% (cautious: only 1 year in 10 freezes later)May 20

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 57576

Dates count from your average last spring frost (May 6) and first fall frost (Oct 7). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
