Grevillea Robusta

Below, you’ll find key tips tailored to this species’ requirements. Whether you’re new to plant care or have plenty of experience, these guidelines are here to support you in keeping your green companion healthy and vibrant.

1. Planting:
   • Choose a location with full sun and well-draining soil.
   • Dig a hole twice the width of the root ball and equal in depth.
   • Place the plant in the hole, backfill with soil, and water thoroughly.
   • Ensure adequate spacing from other plants and structures to accommodate its mature size and spreading canopy.
2. Watering:
   • Water regularly during the establishment period to promote healthy root development.
   • Once established, Grevillea robusta is somewhat drought-tolerant but requires regular watering during prolonged dry periods.
   • Allow the soil to dry out between waterings and avoid overwatering to prevent root rot.
3. Pruning:
   • Prune to maintain shape, remove dead or damaged branches, and encourage a well-balanced canopy.
   • Prune in late winter or early spring before new growth begins.
   • Light, regular pruning helps to maintain a neat appearance and encourages better flowering.
4. Fertilizing:
   • Feed with a balanced, slow-release fertilizer in early spring to support healthy growth.
   • Use fertilizers specifically formulated for native plants, as Grevillea robusta can be sensitive to high phosphorus levels.
   • Reduce fertilization in the winter months or during periods of dormancy.
5. Pest and Disease Control:
   • Grevillea robusta is generally pest-resistant but can occasionally suffer from pests such as aphids or scale insects; treat with insecticidal soap or horticultural oil if necessary.
   • Monitor for fungal diseases like root rot or leaf spot; ensure good air circulation and avoid waterlogged soil.
   • Regularly inspect the plant for signs of pests or disease and address issues promptly.
