Cold night: a minimum of 4 °C or lower while tender plants (tomatoes, beans, courgettes …) are out. Hot day: a maximum of 30 °C or more.\n- Skip watering: a day with 5 mm of rain or more, or the day after one; established beds need no extra water then.\n- Litres per bed: Hearth’s FAO-56 watering need — Penman–Monteith reference evapotranspiration from the forecast, times the crop coefficient of each plant and its growth stage, minus the rain that reaches the roots (80 % of daily rain over 2 mm) — with one soaking per about 12 mm of need, placed on evenly spread days that are not skip days.\n\nForecasts change; frost in hollows and on clear, still nights can come earlier than forecast for the area.
