Its native habitat is in areas with plentiful sunlight. Both overexposure and insufficient sunlight can adversely affect its health and survival.
Temperature
Rock harlequin is a plant native to habitats that commonly experience temperatures of about 68 to 95 ℉ (20 to 35 ℃). It flourishes at these temperatures and might need temperature adjustments in winter to prevent stress.
Fertilizer
Rock harlequin requires regular fertilization to encourage flowering but does not tolerate excess. It needs light amounts of fertilizer applied frequently throughout its entire life cycle, especially during peak active growth and while it is flowering. You will feed your Rock harlequin until it stops blooming.
Pot & Repot
When repotting Rock harlequin, choose a pot that is 1–2 inches (2.5–5.1 cm) larger in diameter and has good drainage. Use a well-draining potting mix, and consider adding perlite for extra drainage. Repot in spring or early summer, then water thoroughly and place in a shady spot at first.
