Native to South Africa, Strelitzia reginae grows in warm, bright conditions where soil stays lightly moist but drains freely. Its natural habitat helps explain why Bird of paradise plant soil should feel open and airy rather than dense or soggy.
This species has thick, fleshy roots that store some moisture, so the best soil for Bird of paradise plant balances steady hydration with good oxygen around the roots. A sandy, loamy, organic-rich substrate suits it well because it holds enough moisture for active growth without staying compacted or waterlogged.
