90% (early: most years still freeze after this)May 2
50% (the "average" last frost)May 19

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 89419

Dates count from your average last spring frost (May 19) and first fall frost (Sep 24). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
