Not planted yet — but the plan for it is final
The practical task and the checklist below are exactly what this lesson will teach. What is missing is the written explanation and the curated links, each one fetched and verified before it ships.
In the meantime the checklist is genuinely usable on its own. Take it outside.
Checklist
- Know which of your plants are phosphorus-sensitive
- Use slow-release or controlled-release products on sand
- Feed at lower rates more frequently, timed to growth
- Avoid feeding immediately before heavy winter rain
