Choosing the Right Pot for Your Bonsai

Bonsai is an art form that beautifully marries nature and creativity, and one of the most crucial elements in this practice is the pot for your tree. The right pot not only enhances the aesthetic appeal of your bonsai but also plays a significant role in the health and growth of the tree. In this post, we will explore the key factors to consider when selecting a bonsai pot, including size, shape, color, and age.

Importance of Pot Size

Choosing the correct pot size is essential for the health of your bonsai. A pot that is too small can restrict root growth, leading to poor health and stunted growth. Conversely, a pot that is too large can hold excess moisture, increasing the risk of root rot.

Guidelines for Selecting Size

Root System: The pot should be large enough to accommodate the root system without crowding. A general rule of thumb for oval and rectangular pots is that the height of the pot equals the size of the nebari, and the width of the pot equals two-thirds of the widest part of the foliage. For round and square pots the width of the pot can be one-third of the canopy of the tree.

Of course, this general rule of thumb needs to be adjusted to the specifics of the tree and the overall design and desired aesthetic appeal. When selecting a pot, consider the proportions of your bonsai.

A tall tree may look better in a deeper pot, while a shorter tree may be more visually appealing in a shallower pot. Aim for balance between the tree and the pot to create a cohesive look. At the end of the day, it is your taste that matters, and it's your choice to complete the design of the tree with the appropriate pot.

One of the things that is being overlooked in many cases is the age of the pot. An old tree will look balanced and in harmony with an old pot with a patina and an aged look and feel. While the same tree in a new pot with no feel of age will look out of balance and artificial.

Shape and Design

The shape of the pot can significantly influence the overall appearance of your bonsai. Different shapes can complement various styles of bonsai, enhancing the visual harmony between the tree and its container. When selecting the pot one of the important aspects is also the design of a tree. If the tree has a more masculine feel the pot should underline this with a strong masculine shape. While a feminine or elegant tree should use a pot with softer lines and a feminine feel.

General Guidelines for Pot Shapes

Formal Upright (Chokkan)

- Recommended Pot Shape: Rectangular or square pots.

- Reason: These shapes provide a sense of stability and structure, complementing the straight, tapering trunk of the formal upright style.

Informal Upright (Moyogi)

- Recommended Pot Shape: Oval or round pots.

- Reason: The soft curves of these pots mirror the natural, flowing lines of the informal upright style, enhancing its organic appearance.

Slanting (Shakan)

- Recommended Pot Shape: Rectangular or slightly angled pots.

- Reason: These shapes help emphasize the tree's slanting posture, creating a dynamic visual effect.

Cascade (Kengai)

- Recommended Pot Shape: Deep and heavy rectangular or round pots.

- Reason: The depth provides stability for the cascading branches, while the weight helps counterbalance the tree's downward growth.

Semi-Cascade (Han-Kengai)

- Recommended Pot Shape: Similar to cascade pots, but slightly less deep.

- Reason: These pots support the tree's growth while allowing for a more subtle downward movement.

Broom Style (Hokidachi)

- Recommended Pot Shape: Wide, shallow pots.

- Reason: This shape accommodates the broad, spreading canopy of branches typical of broom-style bonsai.

Forest Style (Yose-ue)

- Recommended Pot Shape: Shallow, wide trays.

- Reason: These pots allow multiple trees to be planted together, creating a natural forest appearance.

Literati (Bunjin)

- Recommended Pot Shape: Round or tall, narrow pots.

- Reason: These shapes complement the tall, slender trunks typical of literati bonsai, emphasizing their height and elegance.

Root Over Rock (Seki-joju)

- Recommended Pot Shape: Shallow pots.

- Reason: Shallow pots allow the roots to be displayed over the rock, enhancing the visual impact of the design.

Glazed pots or Unglazed pots?

This choice is rather simple.

Glazed Pots are typically used for deciduous trees. Glazed pots come in various colors and finishes, providing a glossy, vibrant look that can highlight the colors of your bonsai. Darker colors can create a striking contrast with lighter foliage, while brighter colors can add a cheerful touch.

Unglazed Pots are typically used for conifers. Unglazed pots are made from natural clay, have a more subdued appearance, and can lend a rustic charm to your bonsai. They are particularly well-suited for traditional styles and can help to emphasize the natural beauty of the tree.

Tokoname bonsai pot Yamaaki — Example - Same tree with two different pots.

On the left is a rectangular pot with a more masculine feel. The pot is too high and too wide. There is no harmony in the overall design. On the right side, the round pot is more feminine (including the legs) and the size is much more balanced with the tree. I believe that more harmony between the pot and the tree is established with the feminine round pot and the tree visually feels more appealing.

Conclusion

Choosing the right pot for your bonsai is a critical decision that impacts both the health of the tree and its visual appeal. By considering factors such as size, shape, color, and material, you can select a pot that not only complements your bonsai but also supports its growth and vitality. Remember, the right pot is more than just a container; it is an integral part of the bonsai art form that enhances the beauty of nature. Happy potting!
