Growing amorphophallus muelleri in a pot
Compost and drainage
Amorphophallus muelleri needs sharp drainage, so this matters more in a pot than in the ground. Use a free-draining mix (add perlite, grit or bark to standard compost), always pick a container with drainage holes, and never let it stand in a saucer of water.
Watering amorphophallus muelleri in a pot
Containers dry far faster than open ground, so amorphophallus muelleri in a pot needs checking more often than the general guidance of "Keep the soil consistently moist throughout the leaf-growth season; taper off sharply as the leaf yellows and the tuber enters dormancy." — especially in summer, wind, or a heated room. Check the top few centimetres with a finger rather than watering on a fixed day.
Potting on
Pot on when roots show through the drainage holes or growth slows noticeably — usually every 1-2 years for a plant this size. Move up one pot size only; jumping several sizes leaves wet compost the roots cannot reach, and that is what rots them.
