Compost and drainage

Subalpine Fir 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 subalpine fir in a pot

Containers dry far faster than open ground, so subalpine fir in a pot needs checking more often than the general guidance of "Regular watering during establishment; naturally sustained by snowmelt and high-altitude precipitation" — 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.

Growing subalpine fir in containers — FAQ

Can you grow subalpine fir in a pot?

Subalpine Fir can be grown in a container while young, but it reaches about 20 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.

What size pot does subalpine fir need?
