A relative phenology instrument

The Orchard Remembers

Grow the same three fictional cultivars through different winters. Warmth can wake a bud; only the path into spring decides whether that helps.

Orchard through the season

Rewrite the winter

Paint warmth or cold directly onto the temperature ribbon. The orchard reruns immediately; the marker and trees move with your edited history.

Seasons the orchard remembers

Bloom marks preserve timing; fruit potential is a rounded relative output, not a harvest forecast.

A transparent relative model for asking “what follows from this weather path?” It omits soil, water, disease, pruning, cultivar biology, orchard management, probabilistic insects, and real-world calibration.
