Woolly grevillea (Grevillea lanigera) is a hardy shrub native to Victoria and New South Wales, Australia. It is tolerant of various soil types and can grow upward or prostrate along the ground. Its low maintenance requirements and willingness to bloom year-round make it roundly admired by gardeners.
Water:
Originating from southeastern Australia's eucalypt woodlands, woolly grevillea prefers infrequent rainfall and moderate watering every 1-2 weeks. Thriving in well-drained soil and full sun, it is typically grown outdoors, reflecting its adaptation to drier habitats and rocky terrains.
Fertilize:
Fertilizing woolly grevillea with a slow-release, low-phosphorus fertilizer in spring and autumn promotes growth and blooms. Apply a light handful per square meter, avoiding over-fertilization. Young woolly grevillea benefits from quarterly feeding, while mature plants need less. Water after feeding for better nutrient absorption.
Pruning:
Woolly grevillea has woolly leaves and bright flowers. Prune in late spring post-bloom to encourage growth and maintain shape. Light trimming of dead branches supports air circulation and disease prevention, while avoiding heavy cuts ensures healthier regrowth and improved flowering in future seasons.
Propagation:
Woolly grevillea propagates well through semi-hardwood cuttings taken from healthy, mature plants during active growth. Cuttings, several inches long with lower leaves removed, should be treated with rooting hormone and placed in a sterile medium under high humidity and warmth for successful rooting.
Repotting:
Woolly grevillea' should be repotted every 2-3 years in early spring to promote growth. Use a slightly larger pot and maintain consistent moisture without waterlogging. Avoid fertilizing for 4-6 weeks post-repotting to prevent root burn during acclimation.
