For darwinia, a well-draining, acidic to neutral soil is crucial. They thrive in full sun to partial shade and require regular but moderate watering, ensuring the soil is not too wet. Begin by preparing the soil with organic matter, plant at the same depth they were in the container, and space adequately. After planting, water thoroughly and mulch to retain moisture. Be aware of the specific requirements of different darwinia species, as they can vary. A slow-release fertilizer can encourage healthy growth. Avoid heavy soils and overwatering to prevent root rot.
