Eucalyptus is one of the most asked-about outdoor plants in Britain — loved for its silvery, aromatic foliage and hated, occasionally, for flopping over in year two. Almost every eucalyptus disappointment traces back to the same two mistakes: buying a single leggy cane, and being too polite with the secateurs. Get those right and it's one of the most rewarding architectural plants you can grow.
Why is my eucalyptus floppy or leaning?
Eucalyptus grows extraordinarily fast — a metre or more a year — and a young tree grown as a single thin cane puts on height quicker than its stem thickens. The result is the familiar lean, or a tree that needs staking forever. The fix is form, not fuss: choose a multi-stemmed or bushy specimen, where the energy is spread across several stems, and prune annually so the plant stays in proportion to its roots. This is why we stock eucalyptus as fuller, multi-stem plants rather than single canes — they hold themselves.
Can eucalyptus grow in a pot?
Yes — and a pot is actually the sensible way to grow it in a town garden, because it limits the tree's ultimate size. Choose a large, heavy container (ø45cm or more — weight matters, as the foliage catches the wind), use a loam-based compost with grit for drainage, and site it in full sun. In a pot, expect a graceful 2–3m plant rather than the 20m forest tree it would become in open ground — which for most terraces is exactly the point.
Watering & feeding
Young eucalyptus is thirstier than its Mediterranean looks suggest — water generously through the first two summers while it establishes, then it becomes remarkably drought-tolerant. In a container, water when the top few centimetres are dry, more in hot spells. Feed lightly in spring; overfeeding drives soft, floppy growth.
Should I prune eucalyptus?
Yes — firmly, every year, in late winter or early spring. Eucalyptus responds to hard pruning better than almost any tree: cut back by a third (or even coppice young plants low) and it regrows dense, bushy and — a bonus — keeps producing the rounded, silvery juvenile foliage florists prize, rather than the sickle-shaped adult leaves. An unpruned eucalyptus becomes a leaning pole; a pruned one stays a silver cloud.
Is eucalyptus hardy in the UK?
Eucalyptus gunnii — the cider gum — is the classic choice for Britain and hardy to around −15°C once established. Young plants in containers appreciate a sheltered spot in their first winter. Compact cultivars such as 'Azura' are hardier and slower-growing still — bred for exactly the pot-grown town garden.
Anything else?
Wind is the main enemy of a container eucalyptus — a heavy pot and an annual prune solve it. And crush a leaf as you pass: the scent alone justifies the space.
