Editing Calophyllum macrocarpum (section)

== Cultivation ==

The species is associated with Southeast Asian forest habitats. Warm, humid conditions with protection from frost are a cautious habitat-based starting point, not a tested hardiness limit.<sup>[[#cite_note-2|[2]]]</sup>

=== Soil and water ===

A moisture-retentive, organic soil with reliable drainage is a reasonable habitat-based starting point for a forest tree of this kind. Avoid treating that inference as a measured soil or irrigation requirement for ''C. macrocarpum''.

=== Sun and humidity ===

Warm, humid air and protection from cold exposure are prudent starting conditions. The source record does not provide a species-tested light threshold, so exposure should not be assigned a fixed full-sun or shade prescription.

=== Seasonal changes ===

As an evergreen tropical tree, it should not be expected to have a temperate-style winter dormancy. Keep moisture more even during warm active growth and avoid prolonged saturation during cooler or less active periods; this is a conservative habitat-based interpretation rather than a documented seasonal schedule.
