About Red Frangipani

Plumeria rubra · also called Red Frangipani, Red plumeria · tropical

Red Frangipani is a deciduous tropical tree or large shrub famed for its intensely fragrant, waxy flowers in shades of red, pink, yellow, and white. Native to Mexico and Central America, it thrives outdoors in frost-free zones and is widely used in Hawaiian lei. Becomes fully dormant and leafless in winter. Sap is a mild irritant and the plant is mildly toxic to pets; keep away from cats and dogs.

Mature size: Outdoors: 3–8 m tall, 3–5 m spread; in containers: 1–2 m

Watch for — Fungal stem or root rot: The most common and serious problem, almost always caused by overwatering in cool conditions; ensure fast-draining soil and withhold water at the first sign of soft, discoloured stem tissue.

How to tell red frangipani needs repotting

Repotting on a calendar is less reliable than reading the plant. For red 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 red frangipani

Every 2–3 years, into bone-dry mix. Red Frangipani's growth habit — deciduous tropical tree or large multi-branched shrub; goes fully dormant and leafless in winter — sets the pace.

What size pot to step red frangipani up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Red 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 red frangipani

Spring or summer, while red 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 red frangipani

Repot dry. Do not water red 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 coarse, well-drained, slightly acidic loam or cactus mix 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 red 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 red 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 red frangipani

Red Frangipani wants coarse, well-drained, slightly acidic loam or cactus mix. Excellent drainage is the single most important soil requirement. Use a cactus and succulent mix, or combine standard potting compost with 30–40% perlite. Ideal pH is 6.0–6.7. Terracotta pots aid drainage and allow soil to dry faster than plastic containers. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting red frangipani — frequently asked questions

How often should you repot red frangipani?

Every 2–3 years, into bone-dry mix for red frangipani. Repot red frangipani every 2–3 years into a snug pot of coarse, well-drained, slightly acidic loam or cactus mix, 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 red frangipani need?

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

Should you water red frangipani after repotting?

No — not straight away. Repot red 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 red frangipani after repotting?

Not immediately. Wait about 3 weeks after repotting red 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.
