Breadfruit
Artocarpus altilis
The Breadfruit tree, known scientifically as Artocarpus altilis, is a tropical plant valued for its large, starchy fruits. Originating from the Indo-Pacific region, it thrives in warm climates and is cherished for its versatility in cooking and nutrition.
Everything it needs
9 essentials at a glance
Watering
Breadfruit trees prefer consistently moist soil, especially during their growing season.
Water deeply once a week, allowing the top 2-3 inches of soil to dry out between waterings. In hotter months, you may need to water more frequently, up to twice a week. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Breadfruit trees thrive in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in an open area with good air circulation. They can tolerate partial shade but will produce fewer fruits. Avoid placing them in areas with heavy shade or near tall structures that block sunlight.
Soil
The ideal soil for Breadfruit trees is well-draining, rich in organic matter, with a pH range of 6.0 to 7.5.
A potting mix that includes compost, peat moss, and perlite is recommended to ensure good drainage. Avoid heavy clay soils that retain water, as this can lead to root rot.
Humidity
Breadfruit trees prefer high humidity levels, ideally between 60-80%.
To increase humidity, consider misting the leaves, placing a humidifier nearby, or grouping plants together. Signs of humidity stress include browning leaf edges and leaf drop.
Temperature
Breadfruit trees thrive in temperatures between 70-95°F (21-35°C) and are sensitive to cold.
They are best suited for USDA hardiness zones 10-12. Protect them from temperatures below 50°F (10°C) as they can suffer damage. During winter, ensure they are in a warm location.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 14-14-14.
Fertilize every 6-8 weeks during the growing season, and reduce frequency in the fall and winter. Signs of nutrient deficiency include yellowing leaves (nitrogen), poor fruit development (potassium), and leaf curling (magnesium).
Pruning
Prune Breadfruit trees in late winter or early spring to shape the tree and remove any dead or diseased branches.
Use sharp, clean pruning shears to make clean cuts. Regular pruning helps improve air circulation and sunlight penetration, promoting healthy growth and fruit production.
Repotting
Repot Breadfruit trees every 2-3 years or when they outgrow their pot.
Signs that it needs repotting include roots growing out of the drainage holes and stunted growth. Choose a pot 1-2 inches larger in diameter, and gently loosen the root ball before placing it in fresh potting mix.
Propagation
Breadfruit can be propagated through seeds or air layering.
For seed propagation, collect seeds from ripe fruit, clean them, and plant them in a seed-starting mix. Keep the soil moist and warm until germination, which can take 2-4 weeks. Air layering involves wounding a branch, applying rooting hormone, and wrapping it in moist sphagnum moss until roots develop.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture and reduce watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Leaf drop
Why it happens
Under-watering or sudden temperature changes.
How to fix it
Ensure consistent watering and protect the tree from cold drafts or sudden temperature fluctuations.
Root rot
Why it happens
Poor drainage and over-watering.
How to fix it
Improve drainage by repotting in fresh, well-draining soil and reduce watering frequency.
Browning leaf edges
Why it happens
Low humidity or nutrient deficiency.
How to fix it
Increase humidity through misting or a humidifier, and consider fertilizing with a balanced fertilizer.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Dry conditions and poor air circulation.
How to fix it
Increase humidity and air circulation, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, focus on fertilizing and watering regularly as the tree begins its active growth phase. Prune any dead or damaged branches to encourage new growth.
Summer
During summer, ensure consistent watering, especially in hotter weather. Monitor for pests and increase humidity if necessary to prevent stress.
Fall
In fall, reduce watering frequency as the tree prepares for dormancy. Continue to monitor for pests and consider light pruning to maintain shape.
Winter
In winter, protect the tree from cold temperatures and drafts. Reduce watering and avoid fertilizing until spring when growth resumes.
Toxicity & Safety
Breadfruit is generally considered safe for pets and children. However, unripe fruit and seeds can be toxic if ingested in large quantities, leading to stomach upset. Symptoms may include nausea and vomiting.
Good to know
How often should I water my Breadfruit tree?
