How to Grow Plumeria
Plumeria rubra
A deciduous tropical tree famous for its intensely fragrant, waxy flowers in white, pink, yellow, or red. Drops leaves in winter and flowers on bare branches in spring. Needs full sun, excellent drainage, and frost-free conditions. Zones 10-12.
Yearly Lifecycle
Care Essentials
Feed every 2 weeks with a high-phosphorus fertiliser from spring through summer to promote flowering. Stop feeding when leaves begin to drop in autumn.
Watch For
- Frangipani rust (orange pustules on leaf undersides)
- Whitefly
- Stem rot from overwatering during dormancy

☀️ Light
Full sun, minimum 6 hours direct sun daily.
Plumeria demands bright, direct sunshine to form flower buds. In the UK, position against a south-facing wall or in the sunniest spot available; grow under glass if your outdoor season is short.
💧 Watering
Water freely in growth, bone dry in dormancy.
From bud break through leaf drop, water thoroughly when the top 5 cm of compost dries out. Once leaves fall in autumn, stop completely and do not resume until new growth appears in spring.
🌱 Fertilizing
High-phosphorus feed every 2 weeks during the growing season.
Use a fertiliser with a high middle number (phosphorus) from spring until late summer to promote flowering. Avoid high-nitrogen feeds which encourage leaf growth at the expense of blooms. Stop feeding when leaves begin to drop.
✂️ Pruning
Minimal — only remove dead or crossing wood.
Flower buds form at branch tips, so avoid cutting stem ends. Prune in late winter before bud break, removing only dead, diseased, or awkwardly placed branches. Wear gloves as the white latex sap is a skin irritant.
🌿 Temperature
Frost-free at all times; ideal growing range 18–32°C.
Plumeria is damaged below 10°C and killed by frost. In the UK, move container-grown plants indoors before the first frost (usually October) and keep in a frost-free, dry location through winter. Dormant plants need minimal warmth — 10–15°C is sufficient.
Growing Tips
Keep it bone dry in winter
When leaves drop in autumn, stop watering entirely. Plumeria stores energy in its thick stems and needs a completely dry dormancy — any moisture during this period is the leading cause of fatal stem rot.
Flowers come from branch tips — never prune them
Every flower cluster emerges from the end of a branch. If you cut branch tips you remove next season's blooms. Prune only dead or damaged wood, and always cut back to a node, never a tip.
Full sun and warmth are non-negotiable
Plumeria needs at least 6 hours of direct sun a day and warm temperatures to set flower buds. A sunny south-facing window is the minimum indoors; outdoors in summer produces the best results.
Pests & Diseases
Pest Whitefly
Identification: Clouds of tiny white-winged insects fly up when foliage is disturbed; sticky honeydew on leaves and sooty mould follow.
- Spray with insecticidal soap solution, covering leaf undersides thoroughly.
- Introduce Encarsia formosa parasitic wasps in a greenhouse setting.
- Apply a systemic neonicotinoid-based insecticide (e.g. imidacloprid) as a soil drench per label instructions.
Pest Mealybug
Identification: White cottony masses in leaf axils and on stems; sticky secretions and ant activity are secondary signs.
- Dab individual colonies with a cotton bud dipped in 70% isopropyl alcohol.
- Spray with diluted neem oil solution every 7 days for 3 weeks.
- Use a systemic insecticide containing acetamiprid or spirotetramat, applied as directed.
Pest Red Spider Mite
Identification: Fine stippling on leaves, bronze discolouration, and very fine webbing on the undersides of leaves in hot dry conditions.
- Mist foliage regularly to raise humidity — mites hate moisture.
- Release predatory mites (Phytoseiulus persimilis) in enclosed growing spaces.
- Apply a miticide containing abamectin or bifenazate, rotating active ingredients to prevent resistance.
Disease Frangipani Rust Coleosporium plumeriae
Symptoms: Bright orange-yellow powdery pustules on the undersides of leaves; upper surfaces show pale yellow spots. Severe infections cause premature leaf drop.
Treatment: Remove and bin (do not compost) all affected leaves. Spray with a copper-based fungicide or sulphur fungicide every 10–14 days until new growth is clean.
Prevention: Ensure good air circulation; avoid overhead watering. Inspect new plants before introducing them to your collection.
Disease Stem Rot Phytophthora spp. / Pythium spp.
Symptoms: Soft, dark brown or black discolouration at the stem base or around wounds; affected tissue turns mushy and may smell unpleasant. Plant wilts and collapses rapidly.
Treatment: Cut back into healthy cream-coloured tissue, dust the wound with powdered sulphur or cinnamon, and allow to callous in a warm dry place for several days before repotting in fresh, fast-draining compost.
Prevention: Never water during winter dormancy; use a gritty, free-draining compost mix; ensure pots have large drainage holes and never sit in water.
