Quick Reference • Frost tolerance = survives below 0°C once established (established root systems + waxy/tough leaves aid recovery). • Most frost-hardy species also handle drought — Australia's cold-dry-winter/hot-dry-summer cycle demands both. • Evergreens (pines, olives, snow gum) suit windbreaks/hedging; deciduous fruit trees (apple, pear, stone fruit) need winter chill to fruit. • Macadamia is a notable exception — not frost tolerant, avoid in frost-prone zones. • Match root behaviour to site: non-invasive roots for small/urban gardens near structures. • Data compiled from/expanded on this guide: Ultimate Frost Tolerant Trees Australia Guide

| Coastal cool regions | Frost + wind + salt tolerance | Banksia, cypress, hardy eucalypts |
Leaf scorch after cold snap? → Frost damage; prune affected growth once new growth resumes.
Tree growing slowly, soil staying wet? → Poor drainage; improve soil structure, add organic matter/raised beds.
Roots rotting, base soft? → Over-watering; reduce irrigation frequency, especially in winter.
Can I plant near a foundation/pipe? → Only species marked "non-invasive" root behaviour above; avoid deep-spreading types (eucalypts, oaks, pines) near structures.
Is my fruit tree not fruiting? → Check chilling-hour requirement for the variety; insufficient winter cold reduces fruit set in apples/pears/stone fruit.
Macadamia dying back after frost? → Expected — macadamia is not frost tolerant; relocate to warm-climate zone or grow under protection.
