Growing pelargonium carnosum in a pot
Compost and drainage
Pelargonium carnosum 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 pelargonium carnosum in a pot
Containers dry far faster than open ground, so pelargonium carnosum in a pot needs checking more often than the general guidance of "When the gritty mix is fully dry, about every 10-14 days in growth; sparingly in summer 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.

Can you grow pelargonium carnosum in a pot?
Pelargonium carnosum is well suited to container growing — at about 50 cm mature it is comfortably pot-sized. A container around 15-20 cm (6-8 in) across gives it room without leaving the compost sitting wet, which is the usual mistake when people over-pot a small plant.
What size pot does pelargonium carnosum need?
Aim for a container 15-20 cm (6-8 in) across. 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.
