Up to 2 weeks before the spring frost reference
The source anchor is the average last spring frost. Use this as an approximate regional starting point.
A NOAA station’s median 32°F freeze date is a different measure. Substituting it is an application calculation, not a published local calendar.
Use the Central North Carolina calendar, with its separate establishment methods. This is not a calendar for every part of North Carolina.
Outside these regions? Use your local Extension planting guidance. A nearby weather station describes climate; it does not establish whether or when to plant this crop.
The reviewed Central North Carolina source provides this maturity reference. Your variety and growing conditions can change the interval.
Count from seed sown directly in the garden.
Maturity references vary with cultivar, harvest size, weather, and establishment method. Keep your seed packet or transplant label alongside the regional calendar.
