How to Grow White Sapote
Casimiroa edulis
In the UK, grow white sapote in a large greenhouse or conservatory, or try outdoors against a warm south-facing wall in the mildest areas only. It is more cold-tolerant than most tropical fruit trees, surviving brief dips to -3C when mature. Feed monthly with balanced liquid fertiliser from April to September and prune in late winter to control size. Regular pruning is essential if growing in containers.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced liquid fertiliser from April to September. Add extra potash when fruiting to support crop development. No feeding is needed in winter.
Watch For
- Glasshouse red spider mite in warm dry conditions under glass
- Scale insects on older stems
- Mealybugs in leaf axils
- Root rot from overwatering, especially in winter
- Anthracnose in humid conditions with poor ventilation

☀️ Light
Full sun; more cold tolerant than most tropical fruit
Needs full sun for best fruiting. In the UK, grow in a large greenhouse or conservatory, or try outdoors against a warm south-facing wall in the mildest areas. More cold tolerant than most tropicals.
💧 Watering
Regular watering; tolerates brief dry spells once established
Water regularly during the growing season. White sapote tolerates brief dry spells once established but fruits better with consistent moisture. Reduce watering in winter.
🌱 Fertilizing
Monthly liquid feed in season; extra potash for fruiting
Feed monthly with a balanced liquid fertiliser from April to September. Apply a slow-release granular feed in spring. Fruiting trees benefit from additional potash.
✂️ Pruning
Prune late winter; regular pruning essential for containers
Prune in late winter to control size and maintain shape. White sapote can grow large — regular pruning is essential for container culture. Remove dead and crossing branches.
❄️ Overwintering
Frost-free overwinter; mature trees tolerate brief light frost
More cold tolerant than many tropicals — can survive brief dips to -3°C when mature. In the UK, overwinter in a frost-free greenhouse or cool conservatory. Young trees need more protection.
Growing Tips
Protect from frost
Overwinter in a frost-free greenhouse or cool conservatory. Mature trees tolerate brief light frosts but young trees need full protection.
Prune to control size
Prune in late winter to control size and maintain shape. White sapote can grow large, so regular pruning is essential for container culture.
Feed regularly in season
Feed monthly with balanced liquid fertiliser from April to September. Add extra potash when fruiting to support crop development.
Keep watered for best fruit
Water regularly during the growing season for the best fruit. The tree tolerates brief dry spells once established but crops better with consistent moisture.
Pests & Diseases
Pest Glasshouse Red Spider Mite
Identification: Fine stippling on upper leaf surfaces. Leaves become dull and bronzed. Fine webbing visible in severe infestations.
- Introduce the predatory mite Phytoseiulus persimilis
- Mist foliage regularly to raise humidity
- Spray with insecticidal soap
- Spray with a miticide if biological control is insufficient
Pest Scale Insects
Identification: Small brown or white oval bumps on stems and leaf undersides. Sticky honeydew and sooty mould on foliage.
- Scrub off with a soft brush dipped in soapy water
- Apply a winter plant oil wash
- Spray with a plant oil-based insecticide during the dormant season
Pest Mealybugs
Identification: White, waxy, cottony clusters in leaf axils and on stems. Sticky honeydew and sooty mould.
- Dab individual bugs with a cotton bud soaked in methylated spirit
- Introduce the ladybird Cryptolaemus montrouzieri as biological control
- Spray with insecticidal soap
- Spray with a systemic insecticide containing acetamiprid
Disease Root Rot Phytophthora spp.
Symptoms: Yellowing leaves, wilting despite moist soil, dark discolouration at the stem base. Roots are brown and mushy.
Treatment: Reduce watering. Repot into fresh, well-drained compost. Cut away affected roots.
Prevention: Use well-drained compost. Avoid overwatering, especially in winter. Ensure containers have adequate drainage holes.
Disease Anthracnose Colletotrichum gloeosporioides
Symptoms: Dark, sunken spots on fruit and leaves. Fruit may rot before ripening. Leaves develop brown patches.
Treatment: Remove and destroy affected fruit and leaves. Improve air circulation.
Prevention: Avoid overhead watering. Ensure good ventilation. Remove fallen debris promptly.
