Plinia costaricensis prefers consistently moist soil, but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler months.

Ensure good drainage to prevent root rot, especially in containers.

Pruning Plinia costaricensis is primarily for shaping and removing dead or damaged branches. Light pruning can be done after fruiting to maintain desired size and encourage bushier growth.

Avoid heavy pruning, which can stress the plant.

Propagation is typically done by seeds, which require careful handling and stratification. Grafting is also a common method for faster fruiting and improved varietal characteristics.

Softwood cuttings can be taken in spring but have moderate success rates.

Repot Plinia costaricensis every 2-3 years, or when rootbound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot that is only slightly larger than the current one to avoid excessive moisture retention.
