A vigorous deciduous small tree, it responds well to full sun and sharp drainage, making it a prized specimen in tropical gardens and a favourite in the lei and ornamental trade.

Mature size: 3–6 m tall (10–20 ft) in the ground; 1–2.5 m in containers.

How to tell celadine frangipani needs repotting

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

Every 2–3 years, into bone-dry mix. Celadine Frangipani's growth habit — deciduous, upright to spreading small tree or large shrub with the characteristic thick, blunt-tipped branches of the plumeria rubra group. — sets the pace. Plumeria rubra 'Celadine' is a classic cultivar bearing large, intensely fragrant golden-yellow flowers with a rich orange-red blush at the centre. A vigorous deciduous small tree, it responds well to full sun and sharp drainage, making it a prized specimen in tropical gardens and a favourite in the lei and ornamental trade.

What size pot to step celadine frangipani up to

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

The best time of year to repot celadine frangipani

Spring or summer, while celadine 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 celadine frangipani

Repot dry. Do not water celadine 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 gritty, fast-draining sandy 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 celadine 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 celadine 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 celadine frangipani

Celadine Frangipani wants gritty, fast-draining sandy mix. Mix coarse perlite or horticultural grit (40–50%) with a loam-based potting compost. Commercial cactus mix with added perlite is a reliable shortcut. Avoid heavy, moisture-retentive composts. pH 6.0–7.0. Terracotta containers help wick excess moisture away from roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting celadine frangipani — frequently asked questions

How often should you repot celadine frangipani?

Every 2–3 years, into bone-dry mix for celadine frangipani. Repot celadine frangipani every 2–3 years into a snug pot of gritty, fast-draining sandy 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.

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

Should you water celadine frangipani after repotting?

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

Not immediately. Wait about 3 weeks after repotting celadine 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.
