Hi Jason,

Thank you for contacting Yates.

Apaganthus is a hardy perennial that will stay green most of the years. With yellow leaves, you may look into the following aspects: 

- Frost Damage. Though the plant can tolerate milt frost, the leaves can get damage during freeze temperature. To prevent frost damage, try Yates Water Wise DroughtShield, which works like sunscreen to help protect your tree. Prolonged exposure to the sun will still result in burning, but the effects will be reduced by spraying with Yates DroughtShield.

- Lack of nutrients. Feed the plant every 6-8 weeks with some 'Yates Dynamic Lifter Soil Improver and Plant Fertiliser' as a complete, soil-conditioning  fertiliser. It's certified for use in organic gardens and will help create a nutrient rich soil for better root growth, stronger plants and more flowers and fruit! It can be used on gardens all year round, including native plants. Click here for more info on this product:

- Sap sucking insects such as aphids mealybugs or scales could cause yellowing on leaves. Try 'Yates Nature's Way Citrus & Ornamental Spray (Pyrethrum Plus Oil Pest Spray)'. Controls a wide variety on insects pests on many edibles and ornamentals.
