Growing Guide
Growing Grevillea wilsonii successfully requires attention to specific environmental conditions and care practices. Here's a comprehensive guide to help you cultivate this beautiful Australian native shrub.
Requirements
Grevillea wilsonii thrives in full sun to semi-shaded areas, needing at least half a day of direct sunlight. It prefers well-draining, acid to neutral soil. Avoid phosphorus-rich or waterlogged soil, as these can harm the plant. This species adapts to various climates but may have limited frost tolerance, so consider your local weather conditions before planting.
Planting Tips
Choose a location with proper sunlight exposure and good drainage. If your soil is heavy clay, improve drainage by adding gypsum and raising the soil level. Plant Grevillea wilsonii in spring or autumn to allow root establishment before extreme weather. Space plants about 1 metre apart to accommodate their sprawling habit and ensure adequate air circulation.
Maintenance
Prune Grevillea wilsonii lightly after flowering to maintain shape and encourage bushiness. Water deeply but infrequently, allowing the soil to dry between waterings. Apply a low-phosphorus, slow-release fertiliser in spring. Monitor for pests such as scale insects or leaf miners, and treat with appropriate organic methods if necessary. Mulch around the base to conserve moisture and suppress weeds.

Its low maintenance requirements make it perfect for busy gardeners. The plant's resistance to drought and ability to withstand light frosts add to its appeal for challenging garden environments.
Problems & Solutions
Grevillea wilsonii, while generally hardy, can face certain challenges in cultivation. Understanding these issues and implementing appropriate solutions ensures the plant's health and longevity.
Common Issues
Grevillea wilsonii may encounter problems such as seed dormancy, affecting germination rates. The plant can be sensitive to excessive moisture, leading to root rot. Pests like aphids, scale, and root weevils may attack the shrub. Poor drainage and phosphorus-rich soils can hinder growth and overall plant health.
Care Tips
To overcome seed dormancy, use scarification techniques or expose seeds to heat. Ensure well-draining soil to prevent root rot. Monitor for pests regularly and treat with organic methods. Prune lightly after flowering to maintain shape and encourage new growth. Water deeply but infrequently, allowing the soil to dry between waterings.
Seasonal Notes
In winter, protect Grevillea wilsonii from severe frost, especially young plants. During summer, increase watering frequency if drought conditions persist. Apply a low-phosphorus fertiliser in spring to support healthy growth. Monitor for signs of stress during extreme weather events throughout the year, providing additional care as needed.
