Everything it needs
9 essentials at a glance
Watering
Mammea Americana prefers consistent moisture, especially during its growing season.
Water deeply once a week, allowing the top 2 inches of soil to dry out between waterings. In the winter, reduce watering to every 10-14 days. 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 light without obstruction. While it can tolerate partial shade, reduced sunlight can hinder fruit production.
Soil
Mammea Americana prefers well-draining, sandy loam soil with a pH range of 6.0 to 7.5.
The soil should be rich in organic matter to support healthy growth. A recommended potting mix includes a blend of peat moss, perlite, and compost to ensure adequate drainage.
Humidity
This plant enjoys moderate to high humidity levels, ideally between 50-70%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Mammea Americana thrives in temperatures between 70-90°F (21-32°C) and is hardy in zones 10-12.
It can tolerate brief periods of heat but is sensitive to frost, so protect it during cold snaps.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 during the growing season.
Fertilize every 4-6 weeks from spring to early fall. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Mammea Americana in late winter or early spring to shape the tree and remove any dead or diseased branches.
Use clean, sharp pruning shears to make clean cuts. Deadheading is not necessary as this plant produces fruit.
Repotting
Repot every 2-3 years or when the roots become pot-bound.
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 follow these steps: gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Propagation is best done via seeds or grafting.
For seeds, soak them in water for 24 hours, then plant in a well-draining mix. Keep the soil moist and warm until germination, which can take 2-4 weeks. Grafting should be done in spring when the plant is actively growing.
