Trunk can eventually reach 3-5 m over decades, with a frond crown spreading 2-4 m wide; much smaller and slower in containers.

Compost and drainage

Soft Tree 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 soft tree fern in a pot

Containers dry far faster than open ground, so soft tree fern in a pot needs checking more often than the general guidance of "Keep the trunk and root zone consistently moist; water into the crown and down the trunk every few days in warm weather" — 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 soft tree fern in a pot?

Soft Tree Fern can be grown in a container while young, but it reaches about 5 m, so a pot is a medium-term home rather than a permanent one. Start it in a 40-60 cm (16-24 in) across planter, expect to pot on as it grows, and accept that container life will keep it smaller than it would be in open ground — which is often exactly what people want.
