Everything it needs
9 essentials at a glance
Watering
Spondias dulcis prefers consistently moist soil, requiring watering every 1-2 weeks depending on the season and climate.
During the growing season, ensure the top inch of soil is dry before watering again. In the winter, reduce watering frequency to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun, needing at least 6-8 hours of direct sunlight daily.
Ideal placement includes south or west-facing locations, where it can receive ample light. While it can tolerate partial shade, reduced light can hinder fruit production and overall growth.
Soil
Spondias dulcis prefers well-draining, sandy loam soil with a pH range of 6.0 to 7.5.
Ensure good drainage to prevent waterlogging, which can lead to root rot. A recommended potting mix includes a blend of potting soil, sand, and perlite to enhance drainage.
Humidity
This plant enjoys moderate to high humidity levels, ideally between 50-70%.
To increase humidity, consider misting the leaves or placing a humidifier nearby. Signs of humidity stress include brown leaf tips and edges, while too much humidity can lead to fungal issues.
Temperature
Spondias dulcis thrives in temperatures between 70-90°F (21-32°C) and is best suited for USDA hardiness zones 10-12.
It is sensitive to frost and should be protected from temperatures below 30°F (-1°C). During winter, maintaining a stable temperature is crucial to prevent stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 14-14-14.
Fertilize every 4-6 weeks during the growing season, and reduce frequency in the fall and winter. Signs of nutrient deficiency include yellowing leaves and poor fruit development.
Pruning
Prune Spondias dulcis in late winter or early spring to shape the plant and remove any dead or diseased branches.
Use clean, sharp pruning shears for best results. Regular pruning encourages better air circulation and light penetration, promoting healthy growth.
Repotting
Repot Spondias dulcis every 2-3 years or when the roots outgrow the pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter, and refresh the soil during repotting to provide nutrients.
Propagation
Propagation can be achieved through seeds or stem cuttings.
For seeds, soak them in water for 24 hours before planting in a well-draining mix. For stem cuttings, take 6-8 inch cuttings from healthy stems, dip in rooting hormone, and plant in a moist potting mix. Best timing for propagation is in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency
How to fix it

How to fix it
Increase watering frequency and ensure the plant is not exposed to extreme heat for prolonged periods.
Fungal infections
Why it happens
Excess humidity and poor air circulation
How to fix it
Improve air circulation around the plant and reduce humidity levels. Use a fungicide if necessary.
Fruit drop
Why it happens
Stress from environmental changes or nutrient imbalance
How to fix it
Ensure consistent watering and fertilization, and avoid sudden changes in temperature or light.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Weak plant health or environmental stress
How to fix it
Inspect regularly for pests, and treat with insecticidal soap or neem oil as needed.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth and fruit development.
Summer
During summer, ensure the plant receives full sun and monitor for pests. Water regularly to keep the soil consistently moist, especially in hot weather.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Continue fertilizing until late fall to support fruit maturation.
Winter
In winter, reduce watering to every 2-3 weeks and keep the plant in a warm location, away from drafts. Avoid fertilizing during this dormant period.
Toxicity & Safety
Spondias dulcis is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. Always monitor for any unusual reactions after consumption.
