Hydrozoning: water-led design before you draw anything
Group plants by water requirement and you can water each group correctly on two days a week. Mix them and you will overwater the tough ones and kill the thirsty ones. In Perth this decision precedes the planting plan and shapes the layout.
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.

Hydrozone plan
Divide your garden into hydrozones — typically high (lawn, vegetables), medium (feature and exotic planting), low (established natives and waterwise planting) and none (dry, unirrigated). Draw the boundaries and estimate the area of each.

Checklist
- Every planted area belongs to exactly one hydrozone
- High-water zones are small, deliberate and near the house
- Zone boundaries follow something physical, not an arbitrary line
- Areas are measured, ready for the irrigation design
