How to repot your Bonsai tree
Regular repotting is crucial to prevent your Bonsai from becoming pot-bound and experiencing nutrient deficiency, which can lead to its decline and eventual death. When a Bonsai uses up the available nutrients in the soil and its roots conform to the shape of the pot, it becomes pot-bound. This restricts growth due to limited space and nutrient availability. By regularly repotting or transplanting your Bonsai, you can provide it with fresh nutrients, promoting healthy growth and ensuring its vitality.
How Often Should I Repot My Bonsai?
The frequency of repotting your Bonsai depends on factors such as pot size and tree species. Fast-growing trees typically require repotting every two years or even sooner, while older and more mature trees can be repotted every three to five years. However, repotting should not be done as a routine task. To determine if your Bonsai needs repotting, carefully examine the roots in early spring. If you observe root circling or overcrowding, it's time to repot. If the roots are still contained within the soil, you can reassess in the following spring.
Many indoor Bonsai are planted in organic soil that retains excessive moisture, leading to problems like root rot. If you purchase a Bonsai with this type of soil, it's important to repot it using appropriate Bonsai substrate in the next early spring or fall.

Best Time for Bonsai Repotting
The optimal time to repot a Bonsai is during the early spring when the trees are still in their dormant phase and the buds are beginning to swell. Repotting at this stage minimizes the negative impact on the tree since it hasn't fully developed foliage yet. Additionally, repotting in early spring ensures that any damage to the root system will be swiftly repaired as soon as the tree enters its active growth phase. While some tree species can tolerate repotting in the fall, it is generally advised to avoid repotting Bonsai during summer or winter.
The right pot for your Bonsai
Choosing a pot that fits the size of your Bonsai and the style you aim to achieve is crucial for the composition. Color, shape, size, design all come into play when choosing a pot. For more information, check the Pot selection article.
