Common Issues
Grevillea 'Bronze Rambler' is susceptible to fungal infections, root rot, and scale infestations. Fungal problems and root rot often occur in poorly-draining soil or wet conditions. Scale insects can cause yellowing leaves and dying stems. Over-fertilisation, especially with high-phosphorus fertilisers, can lead to phosphorus toxicity and plant death.
Care Tips
Plant Grevillea 'Bronze Rambler' in well-draining soil on a slope or raised bed to prevent root rot. Use low-phosphorus, slow-release fertilisers to avoid toxicity. Remove scale with insecticide soap or neem oil. For severe infestations, consider chemical treatments. Ensure proper air circulation and avoid overwatering to prevent fungal issues.
Seasonal Notes
In spring, apply a light layer of mulch and prune after flowering to maintain shape. During summer, monitor watering closely, especially in hot, dry periods. In autumn, check for any pest infestations or fungal issues. Winter care includes protecting young plants from frost in colder regions and reducing watering frequency.
