Planting and growing across the year

Planting is the sow / plant-out window. Growing is daytime air versus this plant’s ideal (59 – 75 °F) and tolerable (39 – 81 °F) ranges.

Planting uses sow / plant-out rules (frost, soil germination, night, and last-sow): green when plantable, blue diagonal when nights or soil are too cold, amber cross-hatch when too hot, faint for other calendar limits. Growing shows daytime air against this plant’s ideal and tolerable ranges across the year.

How these dates are judged

Ideal conditions: Daytime air from 59 – 75 °F.
Suitable conditions: Daytime air from 39 – 81 °F.
Last frost and first frost: Typical spring and fall frost dates for Dallas, shown in the key dates.
Days to harvest: 60–100 days from transplant, from typical days to harvest.
Sowing window: Dated sow and harvest bars use frost dates, soil minima, night limits, and last-sow count-back from typical crop timing. The year strip and weekly chart use the same window: air ratings only colour weeks inside it.

Average 38 to 58 °F · Possible 14 to 77 °F

Growing: too cold

Planting: not sowable

A week is in range when its average low and high sit inside the tolerance band 39 to 81 °F; it is suitable when that average range also overlaps the ideal 59 to 75 °F band and possible readings stay within 39 °F to 81 °F. Crossing a possible limit, or missing the ideal band, makes it tolerable; a possible low below 39 °F makes it tolerable. When a sowing window is calculated, weeks outside that window are uncoloured even if air is in range.

Calculated by Plan & Plant · Method · Data 2019–2026

Frost and suitability dates are typical figures from climate statistics. Microclimates vary; they are not a guarantee.

How we calculated this

Data: ERA5-Land via Open-Meteo, cell 32.78, -96.80, years 2019–2026 (not a 30-year climate normal yet).
Typical and safer dates: Typical last frost is the date after which half of winters in this sample had no more frost; safer is later in the sample so fewer winters still frosted.
Crop rule: Local windows for Cabbage from frost dates, temperature ratings, and crop timing rules.
Confidence: Provisional — short or thin sample for this place.
