Callistemon Green John

How to grow Callistemon Green John

To grow Callistemon ‘Green John’, choose a sunny location with well-drained soil, as this compact bottlebrush thrives in full sun and tolerates a variety of soil types, including clay and sandy loam. Water regularly during the first year to establish strong roots, then reduce watering as the plant becomes drought-tolerant. Apply mulch around the base to retain moisture and suppress weeds, keeping it clear of the trunk. Lightly prune after flowering to maintain a neat shape and promote dense, bushy growth. Fertilise in spring with a low-phosphorus, native-friendly fertiliser to encourage healthy foliage and vibrant red flowers. ‘Green John’ typically grows to around 1 metre tall and wide, making it ideal for low borders, containers, or small native gardens. Its compact form, bright green foliage, and showy flowers attract birds and pollinators, offering both ornamental and ecological value.
