Planting and growing across the year

Planting is the sow / plant-out window. Growing is daytime air versus this plant’s ideal (59 – 70 °F) and tolerable (39 – 75 °F) ranges.

Pea planting and growing weeks in HoustonJANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDECPlantingGrowing
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 – 70 °F.
Suitable conditions
Daytime air from 39 – 75 °F.
Last frost and first frost
Typical spring and fall frost dates for Houston, shown in the key dates.
Days to harvest
55–70 days from seed, 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.

Growing window for Pea: Jan 1 – Mar 24; Sep 5 – Jan 18 (219 days)

Outdoors: weekly temperatures and windows

Temperatures across the year for Houston. Shaded bands are this plant’s ideal and tolerable daytime air ranges. Growing is daytime air suitability; Planting is sow / plant-out conditions (same colour language). Window brackets mark each stretch.

Average 49 to 65 °F · Possible 32 to 82 °F

Growing: tolerable

Planting: not sowable

A week is in range when its average low and high sit inside the tolerance band 39 to 75 °F; it is suitable when that average range also overlaps the ideal 59 to 70 °F band and possible readings stay within 39 °F to 75 °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.

Based on average frost dates.

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 29.76, -95.37, 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 Pea from frost dates, temperature ratings, and crop timing rules.
  • Confidence: Provisional — short or thin sample for this place.
  • Full methodology (algorithm 2026-10-season-6).
