What the guide prints
Spring: 1 to 6 weeks after. AgriLife calls the spring reference the frost-free date. This site applies the offset to the NOAA median (50%) last 32°F date because the guide does not name a probability level.
Fall: 12 to 14 weeks before. AgriLife calls the fall reference the first freeze date. This site applies the offset to the NOAA median (50%) first 32°F date because the guide does not name a probability level.
Days to harvest in the same guide: 70-90. Days to harvest from AgriLife Table 9. The table does not say whether the count starts at seeding or transplanting.
Same weeks, different stations
These cities use their own median 32°F dates. The week offsets are unchanged.
