Last Planting Dates

Average First Fall Frost

Questions often arise on how late a vegetable can be planted in the garden in New York State and still reach maturity or usable size before frost or cold weather stops growth. The last dates listed below for each crop are based on observations at Ithaca, NY. Locate information for your area of the state on  this first frost map.

Most years the crop will reach the harvest-able stage if planted by the date indicated, but yields of crops requiring multiple harvesting (tomatoes, peppers, cucumbers, etc.) likely will be rather light unless the fall weather is warmer than normal, and first frosts are unusually late. In parts of New York where the fall weather averages milder than in Ithaca, planting a week to ten days later might be possible; for cooler areas move the dates 7-10 days earlier.

2012 USDA Hardiness Zone Map

The 2012 USDA Plant Hardiness Zone Map helps gardeners and growers determine which plants are most likely to thrive at a location. For the first time, the map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended. Users may also simply type in a ZIP Code and find the hardiness zone for that area.
