About White Frangipani

Plumeria alba · also called White Frangipani, Nosegay · tropical

Plumeria alba is the classic white frangipani of the Caribbean and West Indies, producing intensely fragrant pure-white flowers with a yellow throat in summer and autumn. A deciduous, fast-growing small tree, it thrives in full sun with excellent drainage and is widely used in lei-making and temple offerings across the tropics.

Mature size: 4–8 m tall (13–26 ft) in-ground; 1–2.5 m in containers.

How to tell white frangipani needs repotting

Repotting on a calendar is less reliable than reading the plant. For white frangipani, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot white frangipani

Every 2–3 years, into bone-dry mix. White Frangipani's growth habit — deciduous, upright, sparsely branched small tree with a rounded or irregular crown; typically multi-trunked when grown in containers. — sets the pace. Plumeria alba is the classic white frangipani of the Caribbean and West Indies, producing intensely fragrant pure-white flowers with a yellow throat in summer and autumn. A deciduous, fast-growing small tree, it thrives in full sun with excellent drainage and is widely used in lei-making and temple offerings across the tropics.

What size pot to step white frangipani up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. White Frangipani stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot white frangipani

Spring or summer, while white frangipani is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting white frangipani

Repot dry. Do not water white frangipani for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty sandy, sharply draining ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set white frangipani at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep white frangipani completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for white frangipani

White Frangipani wants sandy, sharply draining. Use a well-aerated mix: equal parts coarse sand or perlite and a loam-based compost, or a commercial cactus/succulent mix. pH 6.0–7.0. Excellent drainage is critical — P. alba originates in dry, rocky hillside habitats in the Virgin Islands and Puerto Rico and is not adapted to moist soils. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting white frangipani — frequently asked questions

How often should you repot white frangipani?

Every 2–3 years, into bone-dry mix for white frangipani. Repot white frangipani every 2–3 years into a snug pot of sandy, sharply draining, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does white frangipani need?

When is the best time of year to repot white frangipani?

Should you water white frangipani after repotting?

No — not straight away. Repot white frangipani into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise white frangipani after repotting?

Not immediately. Wait about 3 weeks after repotting white frangipani. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
