Expert tips
The key tip
Needs maximum sun and very well-drained soil: that's its xerophytic nature. Water sparingly once established.
The common mistake
Tempting as it is to speed up growth by watering frequently or adding extra soil: it will get sick.
The pro's trick
Trim lightly after flowering to stimulate branching and keep a compact shape.
Care
Sunlight
Place your round-leaved eucalyptus in full sun to optimize the bluish color of its foliage and its growth. It tolerates light partial shade, but this will slow its vigor. Sunny exposure also strengthens its hardiness.
Watering
Water regularly during the first year to establish roots well. Once established in the ground, moderate watering during dry periods is sufficient. Avoid waterlogging, as eucalyptus fears stagnant moisture. In a pot, let the substrate dry slightly between waterings.
Soil and planting
Plant in well-drained, light soil, even poor soil. Adding gravel or sand at planting improves drainage, which is crucial for this species' survival. Eucalyptus adapts well to rocky or chalky soils.
Pruning and trimming
Little pruning is needed on a well-exposed specimen. Remove dead or poorly placed branches in late winter or spring. Light pruning when young helps form a balanced and fuller habit.
Fertilizer
A moderate application of balanced fertilizer in spring is enough. Eucalyptus are undemanding and prefer naturally poor soils. Avoid excess nitrogen, which would promote less dense and less bluish foliage.
Diseases and pests
Round-leaved eucalyptus is generally robust. Watch for powdery mildew in humid, stagnant climates. Indoors in pots, spider mites and whiteflies can be problematic; ensure good air circulation. Perfect drainage prevents root rot.
Did you know?
Eucalyptus cinerea has been favored since the nineteenth century by florists for its bluish leaves, used in floral arrangements and dried flowers. They retain their color and characteristic scent for a long time, making them a staple of European bouquets, despite the tree's Australian origins.
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.
