Care and cultivation
Haworthias are the most shade-tolerant succulents on this site and do well on an east or north windowsill. Use a gritty mix, water only when fully dry, and shield them from hot afternoon sun which causes red-brown scorch. They grow mainly in spring and autumn and appreciate a drier, cooler winter rest. Light: Bright indirect light; tolerates lower light; avoid harsh afternoon sun. Water: Every 2–3 weeks; drought-tolerant, less in winter. Use a Fast-draining cactus mix with added grit.
