Japanese maple is not only very popular with bonsai lovers. The distinctive and very filigree tree with its extremely decorative foliage is also otherwise ideal for a bucket culture. However, the plant should be repotted regularly. You can find out why this is so important and how best to repot the Japanese maple in the article below.
The Japanese maple should be repotted every two years
Why repotting is so important
Many a hobby gardener may wonder why repotting is so important - after all, the little tree is fertilized regularly, so that there can actually be no lack of nutrients. Well, repotting is not only so important because of a possible lack of nutrients, but above all because of the compaction and thus hardening of the substrate. In pots, plant substrate tends to become very dense over time. The result is that water and nutrients can only be absorbed to an insufficient extent and the tree eventually suffers from a deficiency. This problem can be counteracted with fresh, loose substrate.
Choosing the right time
With regard to the right time to repot, the expert minds argue, with two different directions. Both sides have quite good arguments for and against their point of view, so that you can proceed according to the most valid justification.
Repot before sprouting
Usually, Japanese maple should be repotted before a possible budding - ergo already at the beginning of March. The reason for this is that the tree is still dormant until then and has therefore not yet formed any new, fine roots. When repotting, these fine roots are damaged, disrupting the tree's water supply.
Repot during sprouting
The proponents of repotting argue differently about six to eight weeks later, when the delicate foliage has already developed well. The reason for this lies in the energy stored in the form of sugar and starch, which remains in the roots in winter and only reaches the above-ground parts of the plant in spring when they sprout. A later cut is recommended, at least when the roots are cut, as is the case when raising a bonsai.
tips
When repotting the Japanese maple, you should pay particular attention to choosing the right substrate. This should be loose and permeable, but also rich in nutrients. In addition, good drainage in the planter is essential for the well-being of the Japanese maple.
