Growing walking fern in a pot

Verdict
Ideal in pots
Pot size
15-20 cm (6-8 in) across
Mature size
Fronds 10-30 cm long; the plant stays under 15 cm tall but a colony spreads steadily sideways via tip-rooting.

Compost and drainage

Walking Fern 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 walking fern in a pot

Containers dry far faster than open ground, so walking fern in a pot needs checking more often than the general guidance of "Keep substrate evenly moist at all times; check every 3-5 days and never let it dry fully" — 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 walking fern in a pot?

Walking Fern is well suited to container growing — at about 30 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 walking fern 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.
