Expert tips
The key tip
Melianthus major needs dry to moderately moist soil and avoid waterlogging; in mild climates, plant in spring in partial shade away from intense afternoon sun. The blue-green foliage suffers from scorching in excessive intense sunlight.
The common mistake
Planting in humid zones or overwatering: the shrub rots at the roots or collar in winter, especially if it freezes while waterlogged.
The pro's trick
In cold climates (-10°C), grow it in a large pot kept in an unheated greenhouse over winter; you preserve the plant's structure and overwintering is straightforward.
Care
Sun Exposure
Plant your honeybush in full sun for spectacular flowering and optimal blue-gray foliage. It tolerates part shade in very hot regions, but prefers at least 6 hours of direct sunlight. Protect it from strong winds that could damage its large decorative leaves.
Watering
Once established, honeybush is very drought-resistant and requires little water. Water regularly in the first year to promote rooting. In dry regions, moderate summer watering is sufficient; reduce water in autumn to harden the plant before winter.
Soil and Drainage
Choose well-drained soil, as honeybush fears waterlogging and root rot. Poor to moderately fertile soil works perfectly; adding gravel or sand improves drainage. Avoid heavy, compacted soils.
Pruning
Prune lightly in late winter or spring to maintain a bushy shape and encourage branching. Remove frost-damaged or diseased branches as soon as they appear. In mild climates where the plant persists, light pruning rejuvenates growth and stimulates flowering.
Fertilizing
Honeybush is not demanding in nutrients. An annual application of balanced fertilizer in spring is generally sufficient. Avoid excess nitrogen, which promotes foliage at the expense of flowering.
Diseases and Pests
Few problems in appropriate conditions. In overly humid air, leaf spots may appear. Check for spider mites in hot, dry conditions. Maintain good air circulation and avoid excess moisture to prevent fungal infections.
Did you know?
Honeybush owes its scientific name 'Melianthus' to the Greek words 'mel' (honey) and 'anthos' (flower), as its nectar-rich flowers produce abundant nectar that attracts bees and hummingbirds. Its distinctive blue-gray foliage and spectacular scarlet flower spikes make it a favorite in Mediterranean and subtropical gardens, both for its exotic effect and its contribution of pollen and nectar to local wildlife.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
