How do I know when the fruit is safe to eat?

The fruit is safe only when the red capsule has opened naturally on the tree, revealing the yellow arils inside.

Can I grow this in a pot?

It is generally too large for long term container growth, though young specimens can be kept in large tubs.

Care

Keep your tree in a spot with plenty of sun and well draining soil. Watch for yellowing leaves, which often signal that the soil is staying too wet. Only harvest the fruit once the pods have split open on their own to ensure they are safe to eat.

Watering: Water deeply when the top few inches of soil feel dry to the touch.
Feeding: Apply a balanced fertilizer during the active growing season to support fruit production.
Pruning: Prune lightly once a year to maintain shape and remove any dead or crossing branches.
Repotting: Repot young trees every couple of years as they outgrow their containers.
Soil: Well draining, fertile soil
Soil pH: 6.0 to 7.0
Temperature: 15 to 35°C
Humidity: 60 to 90%

Safety

People: Unripe fruit causes severe vomiting and hypoglycemia if ingested.
Pets: The unripe fruit and seeds contain hypoglycin A, which is toxic to both cats and dogs if ingested.
Children: Keep children away from the tree when fruit is developing, as the temptation to pick unripe, toxic fruit is high.
Contact allergens: The sap can cause mild skin irritation in sensitive individuals.
Airborne allergens: The pollen may trigger mild reactions in those prone to seasonal allergies.
Edibility: The fruit is highly toxic unless it has opened naturally on the tree, as unripe arils contain dangerous levels of hypoglycin A.
