Problem 1: Yellowing Leaves
Causes
- Nutrient Deficiency: Iron deficiency is characterized by yellow leaves with green veins, while nitrogen deficiency results in overall yellowing.
- Overwatering/Poor Drainage: Clay-heavy soils in Melbourne and Adelaide often lead to soggy roots.
- Phytophthora (Root Rot Fungus): Often starts with leaf yellowing before plant decline.
The Fix (Aussie Solutions)
- Test Your Soil: Grab a simple pH test kit from Bunnings. Lilly Pillies thrive in slightly acidic soil (pH 5.5–6.5).
- Fertilise Correctly: Use a slow-release native fertiliser such as Osmocote for Natives or Yates Dynamic Lifter. For iron deficiency, apply Searles Iron Chelate.
- Improve Watering Practices: Allow the top few cm of soil to dry before watering again. In clay soils, mix in compost or gypsum to improve the structure.

The Fix (Aussie Solutions)
- Prune Affected Growth: Remove the worst-affected leaves and dispose of them in the bin, not the compost.
- Eco-Friendly Spray: Use eco-oil or Nature’s Way Vegie & Herb Spray. Spray under leaves for best results.
