Frangipani Growing Guide
Everything you need to know to grow beautiful, healthy frangipanis
Welcome to Frangipani Growing
Frangipanis (Plumeria) are stunning tropical plants renowned for their vibrant flowers and intoxicating fragrance. Whether you're a beginner or experienced gardener, this comprehensive guide will help you successfully grow and maintain these magnificent trees.
Native to Central America, Mexico, and the Caribbean, frangipanis have adapted beautifully to Australian conditions and thrive in most climate zones with proper care. Let's explore how to give your frangipanis the best start and ongoing care for years of beautiful blooms.
Planting Your Frangipani
Choosing the Right Location
The location you choose is crucial for your frangipani's success. Consider these factors:
- Sunlight: Frangipanis need at least 6 hours of direct sunlight daily for optimal flowering. More sun = more flowers!
- Drainage: Excellent drainage is essential. Frangipanis will not tolerate waterlogged soil.
- Space: Allow 2-3 meters for mature growth. Consider proximity to structures and other plants.
- Wind Protection: While hardy, young plants benefit from shelter from strong winds.
Soil Preparation
Frangipanis aren't fussy about soil type but prefer:
- Well-draining soil (sandy loam is ideal)
- pH range of 6.0-7.0 (slightly acidic to neutral)
- Addition of compost or well-rotted manure for nutrients
- For pots: Use a quality potting mix with added perlite or sand for drainage
Planting Steps
Step-by-Step Planting
- Cuttings: Allow fresh cuttings to dry for 3-7 days before planting to prevent rot
- Hole Size: Dig a hole twice the width and depth of the root ball
- Positioning: Plant at the same depth as it was in the pot (or bury cutting 10-15cm deep)
- Backfill: Use native soil mixed with compost, pressing firmly to remove air pockets
- Water: Water thoroughly after planting, then sparingly until established
- Stake: Support tall cuttings or young trees with a stake for the first season
Watering Requirements
Proper watering is critical for frangipani health. These plants are drought-tolerant once established but need consistent moisture during the growing season.
Seasonal Watering Guide
- Spring/Summer (Growing Season): Water deeply once or twice weekly during hot, dry weather
- Autumn: Reduce watering as temperatures cool and growth slows
- Winter (Dormancy): Minimal to no water. Frangipanis are deciduous and rest during winter
- New Plantings: Water sparingly until roots establish (2-4 weeks), then follow seasonal guide
Common Watering Mistakes
- Overwatering: The #1 killer of frangipanis. Watch for yellowing leaves and soft stems
- Winter Watering: Never water dormant frangipanis; this causes rot
- Poor Drainage: Standing water will kill your plant. Improve drainage or replant
- Tip: Water in the morning and at soil level, not on leaves
Fertilizing for Maximum Blooms
Proper fertilization produces strong growth and abundant, vibrant flowers. Frangipanis are moderate feeders during the growing season.
Fertilizer Schedule
- Spring (September-October): Apply slow-release fertilizer as new growth emerges
- Summer (November-February): Monthly liquid feed or fortnightly half-strength applications
- Autumn (March-April): Reduce feeding. Last feed by late April
- Winter: No fertilizer during dormancy
Best Fertilizer Types
NPK Ratio
Look for fertilizers with higher phosphorus (middle number) for flowering:
- 5-30-10 (bloom booster)
- 10-20-20 (general purpose)
- Seasol Plus Nutrients
Organic Options
- Well-rotted cow or chicken manure
- Compost tea
- Blood and bone (nitrogen boost)
- Fish emulsion (monthly)
Micronutrients
- Magnesium sulfate (Epsom salts) for lush foliage
- Iron chelate if leaves yellow
- Liquid seaweed for trace elements
- Calcium for strong cell walls
Pruning & Maintenance
Pruning keeps frangipanis compact, encourages branching, and maintains shape. The best time to prune is late winter or early spring before new growth begins.
When to Prune
- Shape Pruning: Late winter (July-August) while dormant
- Deadheading: Remove spent flowers during blooming season
- Disease Removal: Immediately remove any diseased or damaged branches
- Propagation Cuttings: Take in spring or early summer
Pruning Techniques
How to Prune
- Use clean, sharp secateurs or pruning saw sterilized with methylated spirits
- Make cuts at 45-degree angle just above a node or branch junction
- Remove up to 1/3 of growth without stressing the plant
- Allow cut ends to dry and callus naturally (don't seal)
- Remove any crossing or inward-growing branches
- Save healthy cuttings for propagation!
Important: Frangipani sap is toxic and can irritate skin. Wear gloves and eye protection.
Propagation Methods
Frangipanis are incredibly easy to propagate from cuttings. This is the most reliable method and maintains the exact characteristics of the parent plant.
Taking Cuttings
- Size: 30-45cm long, pencil thickness or larger
- Where to Cut: Below a leaf node with clean, straight cut
- Preparation: Remove all leaves and flower buds
- Drying: Store in dry, shaded area for 3-7 days until callused
- Timing: Best in spring/early summer for fastest root development
Planting Cuttings
Pot Method
- Use free-draining potting mix
- Bury 10-15cm deep in pot
- Place in bright, indirect light
- Water sparingly until established
- Roots form in 6-8 weeks
Ground Method
- Plant directly in final location
- Ensure excellent drainage
- Stake for support
- Minimal water until growth appears
- May take 3-4 months to root
Common Pests & Diseases
Frangipanis are relatively pest-resistant but can encounter occasional issues. Early detection and treatment are key to maintaining healthy plants.
Common Problems
Rust Fungus
Symptoms: Orange-brown pustules on leaf undersides, yellowing leaves
Treatment:
- Remove infected leaves
- Apply copper-based fungicide
- Improve air circulation
- Avoid overhead watering
Spider Mites
Symptoms: Fine webbing, stippled leaves, leaf drop
Treatment:
- Spray with strong water jet
- Neem oil or insecticidal soap
- Increase humidity around plant
- Repeat weekly until cleared
Stem Rot
Symptoms: Soft, mushy stems, black discoloration, foul odor
Treatment:
- Cut back to healthy tissue
- Allow to dry completely
- Improve drainage immediately
- Reduce watering frequency
Caterpillars
Symptoms: Chewed leaves, visible caterpillars, droppings on foliage
Treatment:
- Hand-pick and destroy
- Bacillus thuringiensis (Bt) spray
- Encourage natural predators
- Check undersides of leaves
Prevention is Best
- Plant in full sun with good air circulation
- Avoid overwatering (main cause of problems)
- Remove dead leaves and debris regularly
- Quarantine new plants for 2 weeks before introducing

Growing in Containers
Frangipanis adapt beautifully to container growing, making them perfect for patios, balconies, and small spaces. Container culture also allows you to move plants to protect them from extreme weather.
Container Requirements
- Size: Minimum 40cm diameter for mature plants; start smaller for cuttings
- Drainage: Multiple drainage holes are essential
- Material: Terracotta or ceramic pots work well; avoid sealed plastic in hot climates
- Pot Feet: Elevate pots for better drainage and air circulation
Potting Mix
Create a free-draining mix:
- 50% quality potting mix
- 30% perlite or coarse sand
- 20% compost or well-rotted manure
- Add slow-release fertilizer and wetting agent
Special Care for Containers
Container Tips
- Water more frequently than ground-planted (but still allow to dry between waterings)
- Feed more often (every 2 weeks) as nutrients leach faster
- Repot every 2-3 years or when root-bound
- Move to shelter during extreme weather (frost, hail, 40°C+ heatwaves)
- Rotate pot quarterly for even growth
- Top-dress annually with fresh compost
Troubleshooting Common Issues
Why isn't my frangipani flowering?
- Insufficient sun: Needs 6+ hours direct sunlight
- Too young: Plants from cuttings take 2-3 years to flower
- Over-fertilizing: Too much nitrogen promotes leaves over flowers
- Wrong season: Most varieties bloom December-March
- Poor drainage: Stressed plants won't flower
Yellowing leaves
- Natural autumn yellowing: Normal before dormancy
- Overwatering: Most common cause, check soil moisture
- Nutrient deficiency: Apply balanced fertilizer (growing season only)
- Pest damage: Check for spider mites, scale insects
No new growth in spring
- Patience: Some varieties break dormancy later (October-November)
- Cold damage: Frost may have damaged growing tips
- Root rot: Check for soft, mushy roots
- Insufficient chill: Some varieties need cool winter temperatures
Dropped all leaves but still green stems
- Normal dormancy: Perfectly healthy!
- Stress response: Can drop leaves early if stressed
- Don't water: Wait for spring regardless of when leaves dropped
- Scratch test: Stem should be green under bark
