The frangipani might be the most Australian non-Australian tree we have — a tropical import so at home over paling fences and beach-shack yards that summer doesn’t smell right without it. It’s also one of the lowest-effort trees you can own, and the plant most burdened by unnecessary worry: half of frangipani questions are about things that are completely normal. Let’s do care, cuttings, and the reassurance list.
What a frangipani actually wants
Three things: sun, drainage, and to be left alone. Full sun grows the dense, flowering tree of the postcards; shade grows a lanky reluctant one. Sharp drainage is the genuinely non-negotiable part — the frangipani’s one mortal enemy is wet feet, and the rot that follows. Sandy and free-draining soils are ideal; heavy clay calls for a raised mound or a large pot (where they’re famously happy for years).
Watering: generous while young and establishing, then largely optional. An established frangipani rides Australian summers on rain plus the occasional deep drink in brutal stretches, and overwatering kills more of them than drought ever has. Feeding is a light-touch affair — something for flowering plants in spring if you bother at all; rich living produces leaves at the expense of flowers.
One handling note: the white milky sap can irritate skin and eyes, so wear gloves when pruning and keep sap away from your face — ordinary care, not hazmat.
The worries that aren’t
“It dropped all its leaves!” — in autumn/winter: it’s deciduous. The bare, candelabra-branched winter frangipani is the tree working as designed, and it’s why it pairs so well with winter sun over a deck. Leaves return with the warmth. (Early or spotted leaf-drop in the growing season is different — that’s usually rust, covered separately.)
“The branch tips look like blunt stubs.” — that’s where flowers and new leaves emerge. Normal architecture.
“It hasn’t grown much.” — frangipanis are unhurried. Decades-scale trees, human-scale patience.
“It’s not flowering.” — work the short list: not enough sun (the usual answer), too young or recently transplanted, over-fed with nitrogen, or over-loved with water. Fix sun and neglect it better; yellowing leaves in the meantime have their own diagnostic.
Cuttings: the friendliest propagation in gardening
Every big frangipani in the country has descendants from handed-over branches, because propagation is almost comically easy:
- In late spring or summer, take a healthy branch tip 30–60 cm long (or salvage a storm-broken one — the classic origin story).
- Strip most leaves and let the cut end dry in a shaded, airy spot for a couple of weeks until the wound seals over. This callusing step is the whole secret — planting a fresh wet cut invites rot.
- Plant the callused end a hand-depth into barely-moist, very free-draining mix (or straight into a sandy garden spot), stake it against wobbling, and water sparingly — think “remind it occasionally” — until new leaves show it has rooted.
- First flowers typically arrive within a couple of seasons.
Strike rate is high enough that the traditional method — shove it in, ignore it — mostly works too. But the dry-then-plant version is the reliable one.
Pruning and shape
Rarely needed and easily done: cut whole branches back to a junction in late winter before growth resumes, knowing each cut point typically re-shoots with multiple branches (useful for densifying a leggy tree). Avoid enthusiastic annual hacking — the tree flowers on mature wood and its slow elegance is the feature. Mostly, the best frangipani care remains the founding principle: sun, drainage, and benign neglect.
