Last Planting Dates

Average First Fall Frost: October 1

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. Most years the crop will reach the harvestable 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. Note that plant hardiness zones in Columbia and Greene Counties range from 4-6.  The information below pertains to zone 5B which represents most of the land area in our counties.  Please use the plant hardiness zone map in the left sidebar to find the hardiness zone for your zip code and adjust these dates accordingly.
