Garden Weather Tasks

Reads the MET Norway forecast for your garden and turns it into garden tasks for the coming days: frost and cold-night warnings for tender plants in the ground, days when rain makes watering unnecessary, hot days, and how many litres each bed needs from FAO-56 crop water use — with the best days to water.

Example request

Berlin: tomatoes, basil and strawberries

curl -X POST https://greenplotweathertasks.usefulweb.site/api/v1/calculate -H 'content-type: application/json' -d '{"place":"52.47, 13.40","timeZone":"Europe/Berlin","days":7,"plantings":[{"bed":"Raised bed 1","plant":"tomato","areaM2":0.72},{"bed":"Raised bed 1","plant":"basil","areaM2":0.18},{"bed":"Raised bed 2","plant":"strawberry","areaM2":1.08}]}'

Every result contains

inputs (normalised, defaults applied), summary, result (validated against the published schema), units, assumptions, sources, warnings, computedAt and links.
