Soil: Needs well-draining soil — add perlite or orchid bark to a standard potting mix. Good drainage is critical to prevent root rot. Keep it away from cats and dogs.

Cast Iron Plant Yellow Leaves: Wet Mix, Sun, Age or Hunger?
Yellow leaves on a cast iron plant usually mean the mix has stayed wet for too long in a slow-growing, low-light plant. One old outer leaf fading is normal. Bleached patches point to direct sun, and pale, yellowing lower leaves in a dark corner or an old, unfed pot point to light or nutrients.

White or Brown Spots on Cast Iron Plant: Scale, Sun or Spot?
White flecks on a cast iron plant are either the cultivar's own speckling or fern scale, whose male covers are small, ridged and snow-white. Brown or straw-coloured spots usually come from direct sun, cold water on the leaves, or fungal leaf spot, the plant's main disease.
