How to Grow Passionfruit
Passiflora edulis
Passionfruit is a vigorous climber that needs a heated greenhouse or conservatory to fruit in the UK. Provide strong support, full sun, and feed fortnightly with high-potash fertiliser during the growing season. Prune in early spring to a strong framework and train new growth onto wires. Keep above 10C over winter and reduce watering during dormancy. Watch for red spider mite and whitefly under glass.

☀️ Light
Full sun; greenhouse essential in the UK
Full sun is essential for flowering and fruiting. In the UK, grow in a greenhouse or conservatory with maximum light. Insufficient light prevents fruiting.
💧 Watering
Regular in summer; reduce in winter
Water regularly during the growing season, keeping compost moist but not waterlogged. Reduce watering in winter during dormancy.
🌱 Fertilizing
High-potash feed fortnightly in growing season
Feed fortnightly with a high-potash liquid fertiliser during the growing season to promote flowering and fruiting.
✂️ Pruning
Spring prune to framework; train new growth
Prune in early spring, cutting back previous year's growth to a strong framework. Remove dead and weak shoots. Train new growth onto supports.
🌿 Support
Strong trellis; train stems horizontally
Provide a strong trellis or wire system. Passionfruit is a vigorous climber that needs robust support. Train main stems horizontally for best fruiting.
❄️ Overwintering
Keep above 10C; bring indoors before frost
Not frost-hardy. Grow under glass in the UK or bring containers indoors before first frost. Keep above 10C over winter.
Growing Tips
Train for fruit
Provide a strong trellis or wire system and train main stems horizontally for the best fruiting.
High-potash feed
Feed fortnightly with a high-potash liquid fertiliser during flowering and fruiting to boost yields.
Mist to deter mites
Mist foliage regularly under glass to deter red spider mite and raise humidity.
Dry winter rest
Reduce watering in winter and keep above 10C; overwatering during dormancy causes root rot.
Pests & Diseases
Pest Red Spider Mite
Identification: Fine webbing on leaf undersides; leaves develop pale stippling, bronze, and may drop; vine vigour declines
- Mist foliage regularly to raise humidity
- Introduce Phytoseiulus persimilis predatory mites under glass
- Spray with plant oil-based miticide, repeating every 7 days
Pest Glasshouse Whitefly
Identification: Tiny white-winged insects on leaf undersides that fly up when disturbed; sticky honeydew and sooty mould
- Introduce Encarsia formosa parasitic wasp as biological control
- Use yellow sticky traps to monitor and reduce numbers
- Spray with fatty acid-based insecticide, repeating every 5-7 days
Pest Mealybug
Identification: White cottony masses in leaf axils, on stems, and around fruit; sticky honeydew and sooty mould
- Dab with methylated spirit on a cotton bud
- Introduce Cryptolaemus montrouzieri ladybird as biological control
- Spray with fatty acid-based insecticide for heavy infestations
Disease Fusarium Wilt Fusarium oxysporum f. sp. passiflorae
Symptoms: Leaves yellow and wilt from the base upwards; vine collapses despite adequate watering; brown discolouration inside stems when cut
Treatment: Remove and destroy affected plants immediately; do not replant passionfruit in the same soil
Prevention: Use disease-free plants; ensure good drainage; avoid overwatering; rotate planting positions
Disease Passionfruit Woodiness Virus Passionfruit woodiness virus (PWV)
Symptoms: Fruit becomes hard, woody, and misshapen with thick rind and little pulp; leaves may show mosaic patterns and distortion
Treatment: No cure — remove and destroy infected plants to prevent spread
Prevention: Control aphid vectors; buy certified virus-free plants; maintain good hygiene
Disease Root Rot Phytophthora spp.
Symptoms: Yellowing leaves, wilting, waterlogged compost, dark mushy roots; vine declines and may die
Treatment: Repot into fresh, free-draining compost; trim away rotten roots; reduce watering
Prevention: Use well-draining compost; water only when the top few centimetres are dry; ensure pots drain freely
