How to Grow

Choosing a Location 🌞

To thrive, Green Grevilleas need full sun exposure, requiring a minimum of 6 hours of direct sunlight daily. Additionally, consider planting them in sheltered areas to protect against strong winds that could cause damage.

Soil Preparation 🌱

These plants prefer well-drained sandy or loamy soil. Aim for a slightly acidic to neutral pH, ideally between 6.0 and 7.0, and enhance drainage by incorporating organic matter into the soil.
