Plants in the synoum genus thrive in well-draining, humus-rich soil and appreciate a position with dappled or partial sunlight, which mimics their natural understory habitat. Adequate water is important, especially during dry spells. Prepare the area by loosifying the soil and incorporating organic matter. Plant with the root ball level with the soil surface and gently firm the soil around the roots, then water thoroughly. Mulching helps retain moisture. While synoum generally shares these requirements, individual species nuances should be acknowledged for optimal growth.
