⚠️ Troubleshooting / FAQ

Symptom Likely Cause Fix
Yellowing leaves Nutrient imbalance from compacted clay Apply clay-suitable fertiliser; test soil pH
Poor/stunted growth Soil compaction Aerate; mix in organic matter/gypsum
Root rot / dieback Waterlogging Replant in raised mound/bed; improve drainage
Tree leaning or shallow roots Root suffocation Avoid overwatering; ensure mulch doesn't touch trunk
Fruit trees underperforming Heavy clay around root zone Always plant fruit trees in raised beds on clay

Q: What's the single fastest-growing option for shade on clay? Camphor Laurel (12–18m) — but check local invasive species restrictions first.

Q: Best tree if my yard floods seasonally? Swamp Mahogany or River Red Gum — both are bred for wet, heavy soils.

Q: Can I still grow citrus in clay soil? Yes, but only in raised beds — clay's poor drainage is high-risk for citrus root rot.
