Native to tropical parts of the Americas, Mimosa pudica grows in warm, seasonally moist ground that drains freely and stays open to air. That background explains why it prefers soil that feels light and loose rather than dense or sticky.
Its roots are fairly fine and do best when moisture is steady but excess water can move through quickly. The best soil for Sensitive Plant combines gentle moisture retention with good aeration and some organic richness, while a sandy-loamy texture helps prevent compaction around the root zone.
