Soil in Tiny Eden is a mix of components with NPK values and physical properties (drainage, water retention). Assign a plant and the game shows its target soil; your job is to build toward that target, then fix the mix when you repurpose the planter.
Cluster pages
Soil mix helper
Plant + stage selector β required components and targets.
Soil components
Compost, sand, clay and what each adds.
NPK system
How nitrogen / phosphorus / potassium targets work.
Core rules
- Assign first, mix second β Plant Info shows the target for the assigned plant and stage.
- Components are finite inputs β compost, sand and clay come from materials, biomass and shops.
- Wrong soil blocks growth β repurposing a planter for a different crop fails with a soil-composition warning.
- Drainage and water retention tune the mix** β some plants want fast-draining soil, others wet-retentive.
Exact values
The SERP gap here is exact per-plant, per-stage component quantities. The Plant Info sweep is capturing them from the current 1.0 build; until a plant passes its gate, its soil page shows targets with UNKNOWN numeric values instead of inventing them.
The assign-plant β soil target model is official and observed. Quantities are collected per plant and published only when verified in 1.0.
Launch-week sites often show demo-era soil numbers. Our dataset labels build + source + confidence per record.
Drainage and water-retention pages are GSC-gated: they stay merged here until search demand proves standalone pages.
