A useful place to start
Filling, sampling, amending and mulching solve different problems.
01 / Choose the right medium
Separate container mixes from mineral soil and bed-fill decisions.
02 / Read the evidence
Understand the laboratory result before selecting an amendment.
03 / Follow the recommendation
Check the treatment, units and retesting advice instead of guessing a rate.
04 / Plan the surface layer
Choose depth with roots, trunks and maintenance in mind.
05 / Diagnose the physical limitation
Separate compaction, texture and water movement before selecting a material.
06 / Translate the fertilizer label
Match the nutrient recommendation to the label percentages without guessing an application rate.
