Growing fishhook barrel cactus in a pot
Compost and drainage
Fishhook Barrel Cactus 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 fishhook barrel cactus in a pot
Containers dry far faster than open ground, so fishhook barrel cactus in a pot needs checking more often than the general guidance of "When the soil is bone dry, every 10-14 days in summer; once every 4-6 weeks in winter" — 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.
