Repot bonsai - instructions with 5 professional tips

You should know this about the bonsai

The bonsai is an ancient Far Eastern garden art in which trees and shrubs are held in small pots and take on a magical shape.

However, caring for the Mediterranean tree is also an art in itself. With our instructions and the professional tips for repotting bonsai, you will receive all the important information, so nothing can go wrong.

The history of bonsai

As already mentioned, the Japanese word Bonsai (Bon-Sai = tree in a shell) does not describe a separate plant genus or species, but an art form that depicts trees in miniature. The practice originally came from China and was further developed in Japanese Zen Buddhism.

Basically any type of plant with a woody stem/trunk, branches and shrunken leaves can be used for the bonsai art form, as pinching and pruning usually keep the trees under a meter tall.

However, plants with smaller leaves are better suited for bonsai care, as it is easier to create an impressive overall picture here.

Tip 1: How often should you repot bonsai?

Regular repotting is important. A young bonsai is repotted every one to two years. The bonsai forms few new roots in the first year after repotting. It only developed enough roots in the second year, so you don't plant it in a new pot every year.

Older bonsai over 10 years old are repotted every three to five years.

Tip 2: When should you repot bonsai?

The best time to repot bonsai for deciduous trees is from March to the end of April. Conifers can be repotted from September to October. Your bonsai must be repotted when the soil in the old pot is completely interspersed with roots and these are already visible at the edge of the pot.

You should also repot your bonsai in case of deficiency symptoms and root rot. However, if the bonsai seems weak, it is better not to repot it yet.

Tip: When repotting, root pruning is very important. If you would like to learn more about this, have a look at our article Pruning bonsai.

Tip 3: Which soil should you use?

Deciduous bonsai need more humus in the soil than conifers. Young bonsai trees grow faster in light soil with loose soil. Since the bonsai is very demanding when it comes to soil, you should not use normal potting soil or similar.

You can already buy bonsai soil in some garden centers, but you can also easily mix it yourself. Of course, the choice of soil depends on the needs of the respective bonsai species.

Tip 4: After repotting: watering, fertilizing, cutting!?

After repotting the bonsai, the plant is very susceptible to pests. Therefore, protect it from direct sunlight and strong winds for several weeks. It is best to place it in a wind-protected, shady place so that the bonsai can fully recover.

The first fertilization should take place about four weeks after repotting. Until then, the bonsai draws the nutrients it needs from the new soil.

After you have repotted your bonsai, it should be pruned. If you remove some roots, some leaves must also be removed. You can find out how this works and what you have to pay attention to in our article Pruning bonsai.

Of course you should also water your bonsai, but there are a few things to consider. Take a look at our article on watering bonsai.

Tip 5: Yellow leaves on bonsai after repotting?

Your bonsai gets yellow leaves after repotting? This can happen if you didn't trim your bonsai at the crown or fertilized immediately after repotting. Wait at least 4 weeks before fertilizing.

If you cut the roots of your bonsai but don't cut the leaves, some branches and leaves may die off on their own. In our article on Bonsai care you will find out all the other measures that are important for your bonsai.
