Direct answer

Each growth stage is a threshold: when a plant advances, check whether it needs a larger planter (transplant), a soil top-up and more water. The game flags what changed via Plant Info.

What changes between stages

Transplanting

Transplanting moves a plant to a larger planter when its current one caps the stage. The full trigger list lives in the planter size guide; never transplant just because you want to β€” wait for the game's signal or the documented requirement.

Stage-specific planter values

Exact per-stage planter volumes and soil quantities are being captured from Plant Info in the current 1.0 build. Until a plant record passes the gate, its stage values are listed as unknown rather than filled from older demo data.

Evidence note

The stage β†’ demand model is official-consistent and observed in 1.0. Numbers on this page are updated the moment a plant record passes its gate.

MIXED

Several specialist pages still teach playtest-era stage behavior as current. Verify every stage value against the current build before relying on it.
