Growing slender goldfish plant in a pot
Compost and drainage
slender goldfish plant 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 slender goldfish plant in a pot
Containers dry far faster than open ground, so slender goldfish plant in a pot needs checking more often than the general guidance of "When the top third of the soil dries out, roughly every 7–10 days in the growing season and every 14 days 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.
