Hi Kim,

Thank you for contacting Yates.

Looks like some section has dieback near the ground, you may check the following aspects which may cause the dieback of the tree: 

- Soil drainage, plant wilting after heavy rain due to lack of air in the soil. Best to improve soil structure by digging in garden compost and Dynamic lifter into the soil. 
- Chemical damage, has the area been sprayed accidentally by herbicide or chemicals?
- Root damage, may be caused by either pests or disease: 
    - Pest is generally soil born larvae of beetles such as curl grubs feeding on the roots. To control, soil drenching with eco-Neem to eradicate the grubs in soil.  
    - Disease such as root rot or collar rot could cause diebacks in sections. For early infestation, prune off any diebacks and spray the whole plant with 'Yates Anti Rot'. It is a systemic fungicide which is absorbed by the foliage and travels down to the roots, can be used on various plants to control phytophthora root rot, crown rot and collar rot.
