For optimum growth, polytaenia plants require well-drained soil with medium fertility, and full sun to light shade. Start by testing and amending soil to meet these conditions. Dig a hole twice the size of the root ball, place the plant, and gently fill with soil, avoiding stem burial. Water thoroughly after planting. Consistent watering during the first year promotes root establishment. Bear in mind, individual polytaenia species may have specific needs, so appropriate research is crucial for successful growth.
