Glossary
This glossary defines key TPW terms so the method stays consistent. If you are new, Start Here. If you are unsure what is safe now, Find My Phase.
TPW terms are intentionally specific. They keep decisions Phase-appropriate and prevent escalation mistakes.
Key terms
Use these definitions across Field Books, Courses, Learning Paths, and teaching programs.
Phase
A readiness gate that describes what is safe now based on stability, recovery capacity, and evidence clarity. Not a timeline.
Stability
Predictable response to normal care (watering, light, temperature). Stability means the plant is not spiraling from small changes.
Recovery Capacity
The plant’s ability to recover after stress or intervention. Capacity must exist before demand is increased.
Escalation
Increasing inputs or interventions (more water, more fertilizer, stronger treatments). Escalation without capacity causes decline.
Evidence-led
Decisions based on repeated observations and patterns — not a single symptom or urgency.
One change at a time
A core rule: change one variable, observe, then decide. Stacking changes removes clarity and increases risk.
Diagnostic-First
A structured approach that reduces variables, confirms evidence, and prevents false diagnoses before treatment decisions.
Field Book
A bench reference volume organized by Series and subject. Field Books provide depth, checklists, and structured guidance.
Learning Path
A goal-based route that bundles the correct sequence of topics to reduce confusion and prevent skipping steps.
Version Drift
When a method changes over time through improvisation, mixed systems, or inconsistent terminology. TPW programs prevent drift.
