Editing Byrsonima crassifolia (section)

== Climate and site ==

Nance is native from Mexico through Central America into northern and central South America, with populations in the Caribbean. It is associated with seasonally dry tropical climates and can tolerate drought once established. In its native range, fruiting often follows flowering during the transition into the rainy season; exact timing varies by locality.<sup>[[#cite_note-2|[2]]]</sup>

The tree tolerates sandy, acidic, and relatively infertile soils, but cultivated plants still benefit from good drainage, organic matter, and adequate moisture during flowering and fruit enlargement. It can grow in loam or clay loam if the soil does not remain saturated. Full sun promotes compact growth and fruit production. Avoid treating drought tolerance as tolerance of permanently waterlogged roots.<sup>[[#cite_note-1|[1]]]</sup>

=== Soil ===

Nance is characteristic of seasonally dry tropical vegetation, including savanna and open woodland, where soils may be acidic, sandy, nutrient-poor, or lateritic. The species can tolerate these conditions because drainage and seasonal drying are more important than rich soil. In cultivation, use free-draining loam or sandy soil and avoid permanently waterlogged clay.<sup>[[#cite_note-1|[1]]]</sup>

=== Sun and humidity ===

Open native sites provide full sun and relatively dry air during part of the year. Humidity rises with the rainy season, but the tree is not dependent on constant rainforest humidity. Full sun encourages compact growth and fruiting; allow airflow around the crown.

=== Seasonal changes ===

The tree is adapted to a pronounced dry season followed by a rainy growing season. Flowering and fruit development commonly track the transition into or through the rains. Established trees tolerate drought, but supplemental water during flowering and fruit enlargement improves crop consistency; reduce irrigation during cool or naturally dry periods.
