Room firs can hardly be cut into shape
A room fir quickly resents it if it is pruned too heavily. No new branches sprout from the old wood, so that every removed branch is irretrievably lost. The branches cannot be wired. They revert to their old shape when the wire is removed.

You can try to limit the growth of a room fir by capping the top. Cut off the tip, sprout several lateral shoots. This means that the classic shape of the room fir is lost.
Nevertheless, there are attempts to pull the newly sprouted tips hanging, so that an, albeit unusual, bonsai shape is created. However, you have to expect that the room fir will not forgive the pruning and will die.
Carefully prune the roots
In order to limit the growth of the indoor fir, you can use the root ball at Repot trimming. Be careful not to cut away too much.
The bonsai fir tree is only repotted every two years as it does not grow very quickly. The best time to repot is early spring.
Maintain room fir as a bonsai
A room fir as a bonsai maintain, is not easy, as the tree is not so easy to forgive maintenance errors and unsuitable locations.
- Bright, not sunny location
- keep warm in summer
- cooler in winter
- Protect from drafts and contact
In a suitable location, the room fir is very bright but not sunny. In summer it can withstand temperatures between 7 and 22 degrees, in winter it must not be warmer than 5 to 10 degrees.
When watering, make sure that the root ball never dries out completely, but that waterlogging does not occur under any circumstances. It is fertilized every two weeks during the summer with a rhododendron or azalea fertilizer.
Tips
In the trade, room firs are occasionally offered as bonsai. However, these are not classic bonsai, but only trees that have been pulled in a spiral or in other unusual shapes.
