Watering
Keep the soil evenly moist at all times, as this plant thrives in wet conditions.
Feeding
Use a balanced liquid fertilizer during the active growing season.
Pruning
Prune lightly once a year to maintain shape and encourage bushier growth.
Repotting
Repot when the roots fill the container or the soil becomes depleted.

Children
The small seeds should be removed before giving fruit to small children to prevent choking.
Contact allergens
No specific skin irritants are known.
Airborne allergens
Pollen may cause mild respiratory irritation in sensitive individuals during the flowering season.
Edibility

When to plant
spring, early summer
Overwintering
Move the plant indoors or into a greenhouse before temperatures drop below 15 degrees Celsius. Maintain high humidity and keep the soil consistently moist throughout the winter months.
In containers
It is well suited for large containers, requiring at least a 20 liter pot to accommodate its root system.

Seed

  1. 1. Extract seeds from fresh, ripe fruit.
  2. 2. Clean the pulp off the seeds thoroughly.
  3. 3. Plant immediately in moist, well draining soil.
  4. 4. Keep in a warm, humid spot until germination.
