How to Grow Pawpaw
Asimina triloba
Pawpaw is a hardy North American fruit tree producing tropical-flavoured fruit in UK gardens. Plant two trees for cross-pollination in rich, moist, slightly acidic soil. Young trees prefer light shade for the first year or two before gradually increasing sun exposure. Keep soil consistently moist and mulch thickly with compost or leaf mould. Prune minimally in late winter. Fruit ripens late and does not store well, so eat fresh.
Yearly Lifecycle
Care Essentials
Spring with a balanced fertiliser. Mulch with compost.

☀️ Light
Full sun for mature trees; shade young ones
Full sun for mature trees, though young pawpaws benefit from light shade for the first year or two. Gradually increase sun exposure as trees establish.
💧 Watering
Keep consistently moist; dislikes drought
Keep soil consistently moist, especially during fruit development. Pawpaw prefers rich, moist, slightly acidic soil and does not tolerate drought well.
🌱 Fertilizing
Balanced spring feed; generous compost mulch
Apply a balanced fertiliser in spring. Mulch generously with compost to maintain soil moisture and fertility. Pawpaw is a moderate feeder.
✂️ Pruning
Minimal; remove dead wood in late winter
Minimal pruning needed. Remove dead or crossing branches in late winter. Pawpaw naturally forms a pyramidal shape.
🍂 Mulching
Thick mulch to keep roots cool and moist
Mulch thickly with compost or leaf mould to keep roots cool and moist. Pawpaw is a woodland-edge tree and benefits from organic-rich soil.
Growing Tips
Pollination partner needed
Plant at least two trees for cross-pollination; pawpaw will not fruit reliably on its own.
Thick mulch matters
Mulch thickly with compost or leaf mould to keep roots cool and moist; pawpaw is a woodland-edge tree.
Shade when young
Shade young trees for the first year or two, then gradually increase sun exposure as they establish.
Harvest ripe, eat fast
Pick fruit when it gives slightly to pressure and the skin darkens; eat fresh as it does not store.
Pests & Diseases
Pest Pawpaw Peduncle Borer
Identification: Wilting or dropping flowers and small fruitlets. Tiny entry holes at the base of the flower stalk.
- Remove and destroy affected flower stalks promptly
- Encourage ground beetles and other predatory insects
- No chemical treatments are commonly recommended for this pest in the UK
Pest Japanese Beetle
Identification: Metallic green-bronze beetles feeding between leaf veins, leaving a lace-like skeleton.
- Hand-pick beetles in the morning when they are sluggish
- Use pheromone traps away from the tree to draw beetles off
- Not currently applicable in the UK
Pest Slugs and Snails
Identification: Irregular holes in young leaves and slime trails on foliage or around the base of the tree.
- Use copper tape or barriers around young trees
- Apply organic slug pellets (ferric phosphate)
- Encourage hedgehogs, frogs, and ground beetles
- Ferric phosphate pellets (approved for organic use)
Disease Phytophthora Root Rot Phytophthora spp.
Symptoms: Yellowing leaves, wilting despite moist soil, dark discoloured roots, and eventual dieback.
Treatment: Remove and destroy badly affected plants. Improve drainage before replanting.
Prevention: Plant in well-drained soil. Avoid waterlogging. Do not overwater container-grown trees.
Disease Powdery Mildew Erysiphe spp.
Symptoms: White powdery coating on leaves, especially in late summer. Leaves may curl and drop prematurely.
Treatment: Remove badly affected leaves. Improve air circulation around the canopy.
Prevention: Avoid overhead watering. Space trees adequately. Prune for good airflow.
