Cherry of the Rio Grande is native to southern and southeastern Brazil and adjacent parts of Paraguay, Uruguay, Argentina, and Bolivia. It occurs in semi-deciduous and more open secondary forests, generally above about 350 m, and is suited to warm subtropical conditions rather than constant lowland heat.<sup>[[#cite_note-1|[1]]]</sup>

In its native environment it grows in forest soils with seasonal moisture and good internal drainage. A deep loam is useful, but the species is reported to succeed in a variety of soils. For cultivation, the best translation is a moisture-retentive but aerated soil, slightly acid to neutral. Avoid permanently waterlogged ground and dense, stagnant clay. Compacted clay should be raised or amended so the root zone drains after heavy rain. It is more drought tolerant once established than many small fruit trees, but flowering and fruiting benefit from regular moisture.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-2|[2]]]</sup>

Give full sun for the heaviest flowering and fruiting, although young plants tolerate partial shade. Mature plants may withstand short temperature dips near -6 °C, but young plants are more vulnerable and should be protected from hard frost. In cool climates it can grow as an ornamental without producing a dependable crop.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

=== Soil ===

In southern Brazilian and neighboring forest habitats, cherry of the Rio Grande grows in leaf-litter-rich forest soils that retain moisture but drain internally. Deep loam, sandy loam, and amended woodland soil are suitable approximations. Avoid compacted clay and permanently saturated ground, especially where summer rain is heavy.<sup>[[#cite_note-1|[1]]]</sup>

=== Sun and humidity ===

Plants receive filtered light or broken sun in forest and secondary woodland, but established trees fruit more heavily with several hours of direct sun. The native atmosphere is humid, with regular rainfall and good canopy shelter. Young plants tolerate more shade than mature fruiting trees.

=== Seasonal changes ===

The species experiences warm growing periods with a cooler or drier season. Flowering and fruiting follow the local spring–summer cycle, while cooler winter conditions slow growth. Keep the root zone evenly moist during flowering and fruit swell, but reduce watering during cool weather when uptake is lower.
