The rubber tree (lat. Ficus elastica) is a plant species that belongs to the genus of figs (lat. ficus). Large-leaved species are usually kept as houseplants. These are not particularly suitable as bonsai.
For growing as a bonsai, a small-leaved rubber tree species should be chosen
It is better to choose a species with small leaves or a similar plant such as the oleander-leaved rubber tree (lat. Ficus neriifolia) or a fig. Make sure that the leaf size and growth form create a harmonious picture.
How do I shape a bonsai?
By cutting and wiring you can give your bonsai the shape and size you want. Regular pruning is required to avoid bare bonsai. Shorten the shoots again and again to two to four leaves. You can also influence the thickness of the trunk in this way. To do this, only cut off new shoots when the trunk is as thick as you would like it to be.
When it comes to wiring, you have a wide range of design options. The best time for this are the months of July and August. Remove the wire after six months at the latest, otherwise it will grow into the trunk. But sometimes this is desirable, because it makes the wired branch or trunk thicker.
How do I care for a bonsai?
Give your oleander-leaved rubber tree good bonsai soil, which you can get in specialist shops. In principle, the requirements for location and care are the same as for a normally growing rubber tree. It likes it warm and bright and does not tolerate waterlogging or draughts.
Do not water your rubber tree too much, and it only needs small amounts of fertilizer. You should repot your rubber tree about every two to three years, ideally in the spring. With bonsai, use this opportunity to cut back the roots slightly.
The essentials in brief:
- use small-leaved varieties or related plants
- shape by wiring and cutting
- use good bonsai soil
- repot about every two to three years
- cut back the roots slightly
tips
You can grow an attractive bonsai from the oleander-leaved rubber tree. Large-leaved species are less suitable for this.
