How to Grow Abiu
Pouteria caimito
Abiu is a tropical fruit tree that needs consistent warmth, humidity, and moisture to thrive. In the UK it must be grown under glass in a heated greenhouse or large conservatory, as it cannot tolerate any frost. Provide rich, free-draining soil, regular watering, and feed monthly during the growing season. Expect fruit from the third or fourth year once the tree is well established.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced fertiliser during the growing season. Reduce to every six to eight weeks in winter when growth slows.

☀️ Light
Bright light under glass year-round
Bright, indirect to full light under glass. Needs a heated greenhouse or conservatory in the UK with as much light as possible year-round.
💧 Watering
Consistent moisture; never let soil dry out
Water regularly and never let the soil dry out completely. Abiu needs consistent moisture but good drainage to avoid root rot. Reduce slightly in winter.
🌱 Fertilizing
Monthly balanced feed during growing season
Feed monthly with a balanced fertiliser during the growing season to support the fast growth rate. Reduce to every 6-8 weeks in winter.
✂️ Pruning
Prune to control size; responds well
Prune to control size under glass. Remove crossing or damaged branches. Abiu responds well to pruning and can be kept compact.
❄️ Overwintering
Minimum 15°C; heated greenhouse essential
Maintain minimum 15°C year-round. A heated greenhouse is essential in the UK. Reduce watering slightly but never let the plant go cold or dry.
🍎 Harvesting
Pick when bright yellow and slightly soft
Harvest when the skin turns bright yellow and gives slightly to gentle pressure. Eat fresh within a few days as fruit does not store well.
Growing Tips

Pests & Diseases
Pest Scale Insects
Identification: Small brown or white bumps on stems and leaf undersides, sticky honeydew and sooty mould
- Wipe off with a cloth dipped in soapy water
- Introduce biological controls such as parasitic wasps under glass
- Spray with plant oil-based insecticide, repeating as needed
Pest Mealybug
Identification: White cottony masses in leaf axils and on stems, sticky honeydew
- Dab with a cotton bud soaked in methylated spirit
- Introduce Cryptolaemus ladybird as biological control under glass
- Spray with fatty acid or plant oil-based insecticide
Pest Red Spider Mite
Identification: Fine webbing on leaf undersides, stippled yellowing leaves, tiny mites visible with a hand lens
- Increase humidity by misting regularly
- Introduce predatory mite Phytoseiulus persimilis under glass
- Spray with fatty acid-based miticide, ensuring good coverage of leaf undersides
Disease Root Rot Phytophthora spp.
Symptoms: Yellowing and wilting leaves despite moist soil, dark mushy roots, plant collapse
Treatment: Remove from pot, trim rotten roots, repot in fresh free-draining compost. Reduce watering
Prevention: Use well-drained compost and pots with drainage holes. Never let pots sit in water
Disease Sooty Mould
Symptoms: Black powdery coating on leaves and stems, growing on honeydew excreted by sap-sucking insects
Treatment: Wipe off with a damp cloth. Control the underlying pest problem (scale, mealybug, or aphids)
Prevention: Monitor for and control sap-sucking pests promptly
