How to Grow Jaboticaba
Plinia cauliflora
Jaboticaba is a subtropical Brazilian fruit tree that must be grown under glass in the UK, ideally in a heated conservatory or large greenhouse. It is slow-growing but long-lived, producing grape-like fruits directly on the trunk and branches. Keep in a large container with acidic, well-drained compost and maintain high humidity. Patience is needed — trees can take five to ten years to fruit from seed.
Yearly Lifecycle
Care Essentials
Feed monthly with an ericaceous liquid fertiliser during the growing season. Jaboticaba prefers acidic conditions similar to blueberries and benefits from consistent, moderate feeding.
Watch For
- Scale insects
- Mealybug
- Fungus gnats
- Root rot from overwatering

☀️ Light
Bright indirect light, some shade when young
Bright indirect light or dappled sun. Young trees prefer some shade; mature trees tolerate more direct light. Avoid harsh midday sun through glass.
💧 Watering
Consistently moist with rainwater, mist for humidity
Keep compost consistently moist but not waterlogged. Use rainwater where possible as jaboticaba prefers acidic conditions. Mist regularly to maintain humidity.
🌱 Fertilizing
Monthly ericaceous feed during growing season
Feed monthly with an ericaceous liquid fertiliser during the growing season. Jaboticaba prefers acidic conditions similar to blueberries.
✂️ Pruning
Minimal pruning, preserve trunk and main branches
Minimal pruning needed. Remove dead or crossing branches. The tree fruits directly on the trunk and main branches, so avoid removing established wood.
❄️ Overwintering
Heated glass above 10°C, maintain humidity in winter
Keep in a heated greenhouse or conservatory with a minimum temperature of 10°C. Reduce watering slightly in winter but maintain humidity.
Growing Tips
Greenhouse essential
Jaboticaba cannot survive UK winters outdoors. Grow in a heated greenhouse or conservatory maintaining a minimum of 10°C through winter.
Acidic soil
Use ericaceous compost and water with rainwater where possible. Jaboticaba prefers a slightly acidic pH similar to blueberries.
Humidity and watering
Keep the compost consistently moist but not waterlogged. Mist regularly or use a humidity tray — dry air causes leaf drop.
Harvest quickly
Fruits ripen fast and ferment within a few days of picking. Eat fresh, or process into jelly or wine promptly after harvest.
Pests & Diseases
Pest Scale Insects
Identification: Small brown or white bumps on the trunk and branches, sticky honeydew and sooty mould
- Wipe off with a cloth dipped in soapy water
- Introduce parasitic wasps as biological control under glass
- Spray with plant oil-based insecticide
Pest Mealybug
Identification: White cottony masses on the trunk, in bark crevices, and around developing fruit
- Dab with a cotton bud soaked in methylated spirit
- Introduce Cryptolaemus ladybird as biological control
- Spray with fatty acid or plant oil-based insecticide
Pest Fungus Gnats
Identification: Small dark flies hovering around the soil surface, tiny white larvae in the top layer of compost
- Allow the top layer of compost to dry slightly between waterings
- Apply biological control nematodes (Steinernema feltiae) as a compost drench
- Yellow sticky traps to catch adult flies
- Apply Bacillus thuringiensis israelensis (Bti) granules to compost surface
Disease Root Rot Phytophthora spp.
Symptoms: Yellowing leaves, wilting despite moist soil, dark mushy roots, plant collapse
Treatment: Remove from pot, trim rotten roots, repot in fresh free-draining acidic compost. Reduce watering
Prevention: Use well-drained ericaceous compost. Ensure pots have adequate drainage holes
Disease Sooty Mould
Symptoms: Black powdery coating on trunk, branches, and leaves, growing on honeydew from sap-sucking insects
Treatment: Wipe off with a damp cloth. Control the underlying pest problem
Prevention: Monitor for and control sap-sucking pests promptly
