The literal meaning of bonsai is 'plant in a tray'. While the tree itself contributes to one half of the composition, the pot completes the overall image. The 'bonsai' in it's literal sense is judged by the visual impact of both the tree and the pot.
Unfortunately, choosing and locating the correct, or the best, pot to plant your tree into is not easy. While a well-chosen pot will enhance a bonsai and strengthen a design, a poorly chosen or unsuitable design can actually lessen the impact of the tree. Ultimately, until the 'right' pot is found, the tree will never reach it's full potential as a bonsai.
A pot can be expensive investment for your bonsai; buying an unsuitable pot for your tree can mean having to find a more suitable pot in the future. Finding the right pot, first time, is not only satisfying but saves money and helps avoid ending up with a pile of pots that don't quite seem to suit any of your trees!
This article is written to help the enthusiast understand how to go about choosing the correct pot for their tree. My express thanks go to Vic Harris of Erin Bonsai for his help in writing this guide and for providing images of some his pots to illustrate this article.
Choosing the right pot for your tree
Choosing the best pot for a particular tree is not easy. As well as the more mundane factory-made Chinese and Korean pots there are a number of bonsai potters and potteries throughout the world that are able to offer individual and diverse pot designs and glazes to the enthusiast. There are so many available colours, sizes and designs that it can become very difficult to identify exactly which one(s) are best for your tree.
Pot choice is also subjective, ultimately some of the final decision will be made according to your own personal tastes. Some enthusiasts prefer more conservative pot shapes, textures and glazes, other enthusiasts prefer to make more unusual 'individual' choices.
In an effort to help choose the correct 'type' of pot for your tree I have asked Vic Harris to help me draw up some basic guidelines when choosing a new pot for your tree.
To arrive at a good decision, it is useful to break down the choices into 4 parts. Pot dimension, pot shape, pot colour and Texture
Choice 1: Pot Dimensions
The first thing to consider is the size of the pot that you will need. The correct pot dimensions can be achieved using some basic rules according to the dimensions of the tree itself.
It should be remembered that these guidelines are based on aesthetics only. For horticultural reasons, some tree species require larger or smaller pots. Species with very fast growing roots such as Trident Maples often require deeper pots whilst flowering and fruiting species such as Crab Apples require more root run and therefore deeper pots.
Choice 2: Pot Shape
The style of pot that you choose will need to harmonise with the tree.
You need to take a look at your tree and evaluate it's characteristics. Try to decide whether your tree is masculine or feminine. Many trees are a combination of both although usually one is dominant than the other. This is very subjective; for some people a tree may be masculine, for others, it might be feminine. Ultimately as the owner of the tree it is for you to decide. It should be noted though that a firmly masculine tree will never look right in a very feminine oval pot; in turn a feminine tree will always look awkward in a masculine pot.
What makes a tree feminine or masculine?
A masculine tree gives an impression of strength, it might have a heavily tapered trunk, have craggy, mature bark, strong angular branching, it may have deadwood. It may have a straight, powerful trunk or a dense canopy.
A feminine tree will have a more delicate appearance, a smooth trunkline, smooth bark, sinuous movement in it's trunk and branches. A light canopy and slow taper.
Some tree species are predisposed to being considered feminine or masculine; Pines or angular Hawthorns are often considered masculine whereas delicate Japanese Maples will be considered as naturally feminine.
However, a strong, heavily tapered Japanese Maple with delicate leaves and branching could be considered to be a feminine species with masculine features, whilst a tall Hawthorn with craggy, rough bark, gentle curves and very gradual taper could be considered a masculine species with a feminine characteristics. With trees such as these it is necessary to identify which is the strongest feature and reflect it. Is it the craggy, fissured bark of the hawthorn or the gentle curves of the trunk that have the strongest visual impact? Is it the delicate branching of the Maple or the powerful tapered trunk that attracts your eye most?
Fortunately, it is possible to find pot designs that can reflect both femininity and masculinity.
Pots are considered feminine or masculine. Deep pots with strong angular features are considered masculine whilst more feminine pots are shallower with softer lines.
For instance, strong chunky, deep rectangles with sharp corners are very masculine pots, as are square pots. These are suited to thick heavy trunked masculine trees, especially conifers.
For thick-trunked deciduous trees, the corners of the rectangle can be rounded thus reducing the masculinity of the pot a little.
Working down through the scale of masculinity, deep chunky ovals come next and then we have drums/round pots that are androgynous i.e are suitable for a masculine or feminine tree.
After this we move into the feminine pots which are shallow delicate ovals and very shallow round literati pots.

Choice 3: Pot Colour
Once you have decided on the shape of the pot, next you need to think of the colour and texture.
Every tree is unique, although it is possible to generalise about a particular species, each individual tree will have something to pick up on as no two trees are exactly the same and there are always small variations that can be brought out in the pot colour and texture.
The colour of the pot can be used to pick up on a feature of the tree and therefore helps the tree and pot colour 'work' well together. The colour in the tree that is complimented can be that of the bark, for instance an unglazed red/brown pot picking up the bark of a Juniper. It can compliment the colour of the leaves through the summer or the autumn colour. On fruiting or flowering trees, the colour of the pot can be used to compliment the colour of the flowers or the berries.
Examples of pot colour combination with bonsai by Harry Harrington
Although you generally want the colour and texture of a pot to match some characteristic of the tree, sometimes contrasts can work very well, for example, the red leaves of a red-leaved trees work well with a blue pot.
The colour can also be used to accentuate the energy of the tree. Warm colours such as browns, reds, oranges and yellows provide a feeling of warmth and stability to the tree whereas cold colours such as blues and greens can balance and refresh the overall composition.
Warm and cold colours can be used to contrast with a bonsai. Warm colours can be used for tiny (mame-sized) bonsai to exaggerate their colour whereas cool colours can be used to tone down bright-leaved species.

Choice 4: Pot Texture
Textures in a pot are again used to compliment a tree. Smooth clay finishes are suitable for more feminine trees whereas heavily textured pots bring out the masculinity and wildness in a tree.
This pot is very textured, it has a very coarse, gritty feel to it and would be suitable for most pines.
can be seen in this article, choosing the correct pot is not simple
but it can be learnt. Ultimately, a combination of personal tastes,
knowledge and experience makes the process much easier.
When buying pots for your bonsai try to make sure you know the pot measurements needed for a tree. It is no good buying a suitable pot only to find it is too big or small for your tree.
Have a good idea of the shape that will suit the masculinity or femininity of your tree.
Have a good idea of the colours and textures that will suit your tree.
Don't be embarrassed to ask the advice of the bonsai nursery or the potter you are buying from, an experienced potter or bonsai nursery will always be able to give you a choice of suitable pots to choose from. However, always try to have a picture of your tree to hand as this makes the nursery or potter's job much, much easier!
