Know when
Watering, feeding and pest checks for each planting, worked out from what the plant needs, and when to sow, plant out and expect a harvest, counted from your frost dates. Watering that steps aside when it is going to rain, and tells you why.
Forecasts work anywhere: NOAA in the US, MET Norway everywhere else. Hardiness zones are looked up for US gardens only for now, and planting and care timings come from US extension services — outside the US, treat them as a starting point and check local advice.
