Beginner’s Guide to Bonsai Pots and Trays
A bonsai pot is a specialist container designed to support the health, root development, and presentation of a miniature tree. Unlike standard plant pots, bonsai pots are shallow, have multiple drainage holes, and are sized to complement the proportions of the tree rather than simply contain the roots.
Choosing the right pot is one of the most important decisions you’ll make as a bonsai grower. The pot affects not just how your tree looks, but how it grows; influencing drainage, root health, and moisture retention. This guide covers everything a beginner needs to know, from size and material to colour and style, so you can make a confident choice when repotting or buying for the first time.
Quick recommendation: Which bonsai pot do you need?
- Plastic training pot – the right starting point for most beginners. Lightweight, affordable, and ideal while the tree is still developing its structure.
- Fine glazed ceramic pot – the best choice for indoor growers with an established tree. Adds colour and visual appeal. Choose a tone that complements the foliage.
- Unglazed ceramic pot – suited to outdoor species and traditional styling. More breathable than glazed alternatives, with earthy tones that complement rugged bark.
- Tokoname or specialist Japanese pot – for experienced collectors with mature trees, where the pot is part of the display.
For most beginners, start with a plastic training pot. Move to ceramic once the tree’s structure is established and you are ready to display it.
This guide covers the essentials of choosing a pot size, shape and colour, the different pot types available, and how to pair your pot with the right tray.
How do you choose the right bonsai pot?
Choosing the right bonsai pot is one of the most important decisions you’ll make as a beginner. The pot affects your tree’s health, stability, root development, and overall appearance, so it’s essential to understand what to look for before you buy. Here are the key factors that truly matter when selecting a bonsai pot.
Pot Size
Pot size affects root health, drainage and how balanced the tree looks. For exact sizing by pot shape, see our guide to choosing the right pot.
Pot Shape
Pot shape affects how the tree is perceived, from soft and informal to structured and upright. For indoor bonsai, pair your pot with a suitable drip tray.
Drainage
Strong drainage is essential for healthy roots.
Always choose a pot with:
- Multiple drainage holes (not just one)
- Space for mesh to prevent soil loss
- A base design that avoids water pooling
Good drainage prevents root rot and ensures your bonsai can breathe. Pairing your pot with a bonsai humidity tray can also help manage moisture levels and prevent spillage, making it an ideal accessory for beginners.
Colour
Pot colour should complement rather than overpower the tree, and is ultimately a matter of personal preference within that balance.

Speciality bonsai pots
Speciality pots cater to specific tree sizes, styles and traditions.
- Tokoname pots — hand-crafted in the Tokoname region of Japan, these are exhibition-quality pots valued for their refined finish and durability. Best suited to mature, well-developed trees where the pot is part of the display.
- Shohin pots — designed for trees under 25cm in height. Precision sizing is important as a slightly oversized pot throws off the proportions of a small tree.
- Mame pots — for the smallest trees in a collection. Sizing is critical; even a centimetre of extra space can look unbalanced at this scale.
- Chinese pots — typically feature stronger, more vivid designs and decorative detailing. A good match for trees with bold character or flowering species.
- Japanese pots — tend toward a refined, minimalist aesthetic. Well-suited to trees where subtlety and restraint are part of the styling.
- Plastic and mica pots — practical, durable and affordable. A good choice for development stage trees or growers who prioritise function over presentation.
- Mesh-integrated pots — feature built-in drainage mesh which prevents soil loss while maintaining excellent drainage. A useful practical detail for growers who repot regularly.

Where do you start with bonsai pots?
For most beginners, a plastic training pot is the right first choice; practical, affordable, and well-suited to the development stage. In our experience, the most common mistake is moving to a display pot too early, before the tree’s structure is established enough to justify it. Focus on getting the size and drainage right first, then consider aesthetics as your tree develops.

Bonsai Pots and Trays FAQs
Common questions about bonsai pots and trays, answered.
What size bonsai pot do I need?
As a general guide, the pot depth should match the trunk thickness at the base, and the length should be roughly two thirds the height of the tree for upright styles. A pot that is too large slows development by retaining excess moisture around the roots. A pot that is too small restricts root growth and dries out too quickly. When in doubt, err slightly smaller rather than larger.
What is the difference between glazed and unglazed bonsai pots?
Glazed pots have a fired ceramic coating that adds colour and reduces moisture loss through the pot walls, making them better suited to indoor species that prefer stable moisture levels. Unglazed pots are more breathable, allowing the soil to dry more evenly, which suits outdoor species and those that prefer drier conditions. Glazed pots are generally the better choice for beginners with indoor trees.
Do bonsai pots need drainage holes?
Yes, always. A bonsai pot without drainage holes will cause water to pool at the root base, leading to root rot. Choose a pot with multiple drainage holes rather than just one, and cover them with mesh to prevent soil loss while allowing water to drain freely. This is the single most important functional requirement of any bonsai pot.
When should I repot my bonsai?
Most beginner trees benefit from repotting every two years in early spring before new growth begins. Signs that repotting is needed include roots circling the base of the pot, water draining very slowly, or the tree becoming unstable in the pot. Repotting refreshes the soil, trims congested roots, and gives the tree renewed vigour for the growing season ahead.
Can I use a regular plant pot for bonsai?
In the short term yes, but standard plant pots are generally too deep, poorly proportioned, and often have insufficient drainage for bonsai. A purpose-made bonsai pot is shallower, sized to the tree’s proportions, and designed to promote the root spread and drainage that bonsai cultivation requires. For a training stage tree, a plastic bonsai training pot is a far better choice than a standard houseplant pot.
What is the difference between a training pot and a display pot?
A training pot is used during the early development stage when the tree is still being shaped and the root structure is being established. These are typically plastic, larger, and prioritise function over aesthetics. A display pot is used once the tree has developed its character; these are ceramic, sized to the tree’s final proportions, and chosen to complement the tree’s style visually.
How do I choose the right pot colour for my bonsai?
The pot should complement the tree rather than compete with it. Earth tones, browns, greys and muted greens, suit most outdoor and naturalistic styles. Metallic blues, whites and greens work well with flowering or fruiting indoor species. As a general principle, choose a colour that harmonises with the foliage or bark rather than drawing the eye away from the tree.
Do I need a tray with my bonsai pot?
For indoor bonsai, yes. A drip tray protects surfaces from water damage after watering and, when set up with pebbles and water, raises humidity around the tree. Choose a tray at least 2 to 3cm wider than the pot base on each side. For outdoor bonsai, a tray is not essential but can be useful if the tree is placed on a surface that could be stained by drainage water.
