Planting and growing across the year

Planting is the sow / plant-out window. Growing is daytime air versus this plant’s ideal (21 – 35 °C) and tolerable (13 – 38 °C) 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 21 – 35 °C.
Suitable conditions: Daytime air from 13 – 38 °C.
Last frost and first frost: Typical spring and fall frost dates for Leeds, shown in the key dates.
Days to harvest: 50–65 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 Green bean: Jul 23 – Aug 15 (24 days)

Outdoors: weekly temperatures and windows

Temperatures across the year for Leeds. 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.

Growing: tolerable

Planting: suitable

A week is in range when its average low and high sit inside the tolerance band 13 to 38 °C; it is suitable when that average range also overlaps the ideal 21 to 35 °C band and possible readings stay within 0 °C to 38 °C. Crossing a possible limit, or missing the ideal band, makes it tolerable; any chance of frost (possible low below 0 °C) makes it too cold. 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 53.80, -1.55, 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 Green bean from frost dates, temperature ratings, and crop timing rules.
Confidence: Provisional — short or thin sample for this place.
