Everything it needs
9 essentials at a glance
Watering
Spondias mombin prefers well-drained soil and should be watered deeply but infrequently.
Water every 1-2 weeks during the growing season, allowing the top 2 inches of soil to dry out between waterings. In the winter months, reduce watering to once every 3-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in an open area where it can receive ample sunlight without obstruction. While it can tolerate partial shade, reduced light may hinder fruit production and growth.
Soil
Spondias mombin prefers sandy loam or well-draining soil with a pH range of 6.0 to 7.5.
It requires good drainage to prevent root rot, so consider using a potting mix that includes perlite or sand to enhance drainage.
Humidity
This plant enjoys moderate humidity levels of around 40-60%.
To increase humidity, mist the leaves regularly or place a humidity tray filled with water and pebbles beneath the pot. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Spondias mombin thrives in temperatures between 70-95°F (21-35°C) and is hardy in USDA zones 9-11.
It can tolerate brief periods of cold down to 30°F (-1°C) but should be protected from frost. During extreme heat, provide some shade to prevent stress.
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 feeding in the fall and winter. Signs of nutrient deficiency include stunted growth and yellowing leaves.
Pruning
Prune Spondias mombin in late winter or early spring to shape the plant and remove any dead or damaged branches.
Use clean, sharp pruning shears for best results. Deadheading is not necessary, but removing spent fruit can help improve air circulation.
Repotting
Repot Spondias mombin every 2-3 years or when it outgrows its pot, indicated by roots emerging from drainage holes.
Choose a pot that is 1-2 inches larger in diameter. To repot, gently remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Propagation can be achieved through seeds or grafting.
For seed propagation, collect ripe fruit, extract the seeds, and plant them in well-draining soil. Keep the soil moist and warm until germination occurs, which can take 2-4 weeks. Grafting is best done in spring when the plant is actively growing.
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. Consider fertilizing with a balanced fertilizer.
Leaf drop
Why it happens
Under-watering or sudden temperature changes.
How to fix it
Ensure consistent watering and protect the plant from drafts or extreme temperature fluctuations.
Browning leaf tips
Why it happens
Low humidity levels.
How to fix it
Increase humidity by misting the plant or using a humidity tray.
Root rot
Why it happens
Poor drainage or over-watering.
How to fix it
Ensure proper drainage and allow the soil to dry out between waterings. If root rot occurs, repot the plant in fresh soil.
Pest infestations (e.g., aphids, spider mites)
Why it happens
High humidity and poor air circulation.
How to fix it
Regularly inspect the plant and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, focus on fertilizing and watering regularly as the plant begins its active growth phase. Prune any dead or damaged branches to encourage healthy growth.
Summer
During summer, ensure consistent watering, especially in hot weather, and monitor for pests. This is also the time for fruit development, so keep the plant well-fed.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Continue to monitor for pests and remove any spent fruit to maintain air circulation.
Winter
In winter, water less frequently, allowing the plant to rest. Protect it from cold drafts and consider moving it indoors if temperatures drop significantly.
