Saws and Knives: Cutting Larger Bonsai Branches
When faced with branches, trunks, or roots that exceed the capacity of pliers and cutters, bonsai saws become essential. Remember that Japanese pruning saws are designed to cut on the pull stroke, drawing the saw towards you. Avoid applying excessive forward pressure, as this can bend or break the delicate blade. To refine cuts and smooth wounds left by saws and pliers, grafting knives are ideal. These knives, similar to those used by professional gardeners, provide clean, precise edges.
Root Care and Repotting Bonsai Tools
Removing a bonsai root ball from its pot requires specialized tools. Sickle knives and sickle saws are designed to cut along the inside edge of the pot, effectively separating the root ball without damaging the container. Working with roots is made easier and cleaner with solid, angular plastic bowls, providing a dedicated space for root work and soil mixing. Root hooks and root rakes, available in various sizes and configurations with one, two, or three tines, are crucial for untangling root balls, gently combing through roots, and removing old soil trapped within the root system.
Root-pruning is efficiently performed with robust standard shears, featuring large, strong blades and sturdy handles. For particularly thick and stubborn roots, a root plier or saw may be necessary to manage the tougher sections effectively.
For bonsai soil preparation, especially when using granular components like Akadama, Kanuma, and pumice, sieving is a vital step. This process separates different grain sizes and eliminates fine, dusty particles that can impede drainage. Stainless steel sieve sets with varying mesh sizes are specifically designed for this purpose. Soil scoops of different sizes and shapes are essential for accurately filling bonsai pots, particularly for reaching under low-hanging branches. To ensure soil settles into all crevices among the roots, chopsticks or bamboo sticks can be used. However, exercise caution to avoid root damage by applying gentle pressure only. A tweezer spatula proves invaluable for applying moss, removing weeds, pressing down wet moss onto the soil surface, and extracting persistent weeds with precision.
Wiring and Bonsai Wire Tools
Wiring bonsai branches for shaping and styling necessitates specific tools and materials. Bonsai wire, available in various diameters, is fundamental. Wire cutters are essential for cleanly snipping wire, and pliers are needed for bending and manipulating wire, as well as for jin work on deadwood. These wiring tools come in different sizes; smaller tools are particularly suited for working with shohin bonsai. Bonsai wire is typically made from annealed aluminum or copper. Aluminum wire is often recommended for beginners due to its greater pliability and ease of application.
Tools for Branch Bending and Tree Protection
For significant bending of branches or trunks, protective measures are critical to prevent wood breakage and bark tearing, and to aid healing of minor cracks and fissures. The traditional technique involves tightly wrapping the area to be bent with wet raffia before applying wire. Alternatives include fusing rubber tape (applied over gauze) or strips of bicycle tube.
Thin, transparent rubber tubes, such as fish tank or infusion hoses, are effective in protecting trunks, branches, and roots at points where fixation or guy wires are attached. For heavy bending operations, specialized tools like ergonomically designed, rubber-padded steel levers are available. Screw clamps in various shapes and sizes can also be useful for specific bending tasks. Turnbuckles can incrementally tighten strong guy wires to achieve gradual bending adjustments. Iron rebars, used with wooden wedges as a counter-lever and guy wires for fixation, can provide substantial leverage for bending thick trunks.
Deadwood Carving Tools and Techniques
The art of deadwood creation in bonsai aims to achieve a natural aesthetic, concealing any evidence of human intervention. Paradoxically, realizing this natural look requires a wide range of specialized tools.
The branch splitter is a sharp plier designed for creating multiple splits in dead branches and stumps, adding texture and age. The jin plier is used to pull fibers on coniferous trees with fibrous wood or to break off small wood particles on deciduous trees with less fibrous wood, further enhancing the natural appearance of deadwood.
A slim chisel, kept moderately sharp, is ideal for lifting wood fibers to create depth and texture. Loop knives and carving hooks are used to peel bark and carve shallow furrows that follow the natural grain of the wood, mimicking natural weathering processes.
Numerous carving tools of varying shapes, often sold in sets, are available in different qualities and sizes. These tools are used for shaping, smoothing, contouring, narrowing, and hollowing out deadwood, allowing for detailed and artistic manipulation.
To eliminate the last traces of tool marks and remove protruding wood fibers, a gas torch fueled with lighter gas is highly effective. After scorching the wood, the charred layer is brushed away using steel, brass, or nylon brushes, revealing a naturally aged surface.
To preserve decayed deadwood, wood hardener, consisting of liquid plastics diluted in acetone, can be applied. Japanese jin liquid, primarily composed of lime sulfur, is commonly used to whiten deadwood and provides some preservative properties, enhancing the visual contrast and longevity of the deadwood features.

For extensive deadwood work with powerful electric tools, consider additional protective gear such as an overall, gloves, a dust mask, and even a helmet. Maintain full concentration, handle the machine firmly, and exercise caution with speed controls and power buttons.
The “Dremel” is a popular small rotary tool compatible with a wide array of bits with a 1/8″ (3mm) shank. Similar machines from other manufacturers often use the same bits, including rotating brushes made of nylon, brass, or steel for bark removal and deadwood smoothing, as well as various cutters, grinders, and abrasive wheels.
The “Makita” is a favored larger die grinder among bonsai enthusiasts, designed for bits with a 1/4″ (6mm) shank. Other manufacturers offer comparable die grinders. Selecting a machine with a speed control dial is crucial, as different bits require varying speeds. A broad selection of powerful bits is available for these larger power tools, including rotating brushes of different materials, cutting wheels, circular saws, grinding bits, and abrasive wheels in numerous shapes. Due to their significant power and weight, large die grinders can be challenging and potentially hazardous to use, making them less suitable for beginners and those without extensive handyman experience.
Some bonsai professionals utilize sandblasting machines for deadwood refinement. These are large, expensive systems requiring a specialized workspace, protective equipment, and specific expertise. However, sandblasting can produce highly compelling deadwood effects.

Tool Maintenance and Sharpening
Maintaining your bonsai tools is essential for their longevity and performance. Rust erasers (like “Clean Mate”) effectively remove rust and dirt from tool blades. For sharpening, various grindstones are available. Sharpening requires practice, so it’s advisable to practice on older, less valuable shears first. Regularly disinfect your bonsai tools to prevent the spread of fungi, bacteria, or viruses between trees. Gun oil or camellia oil are suitable for lubricating hinges and blades, ensuring smooth operation and preventing rust. Coco brushes are useful for sweeping trunks, nebari (root flares), soil surfaces, shelves, tables, and tools, keeping your bonsai workspace tidy.
Watering Tools and Systems
For small bonsai collections, a ball-shower or watering can is adequate. Watering cans should have a fine nozzle and a long neck to generate sufficient pressure for a gentle, even spray. For larger collections, a garden hose with a sprinkler stick is more efficient. Click here for an image of watering tools in action.
Spray cans, both pump-up and finger-pump types, are necessary for misting bonsai with water, applying plant protection products, or administering foliar fertilizer solutions.
For those with busy schedules or frequent travel, an automated bonsai watering system can be invaluable. For short periods, a simple lawn sprinkler with a timer can provide basic irrigation. More sophisticated and reliable systems like Gardena MDS, Tropf-Blumat, misting systems, and flooding systems are available for comprehensive automated watering. While these systems can be a significant investment for larger collections, they offer substantial convenience and ensure consistent hydration.
Tap water quality can be a concern for bonsai, as it often contains high levels of limescale and sometimes chlorine, which can be detrimental, particularly to maples and azaleas that prefer soft water. Well water can also be hard and contain iron. Therefore, collecting rainwater is highly beneficial. A simple rain barrel connected to a downpipe or a larger water tank can effectively capture rainwater. An ideal setup is a large underground cistern with a hand-operated or electric pump for convenient water access.
Bonsai Turntables for Efficient Work
Working on bonsai often requires rotating the tree frequently, which can scratch surfaces. Lifting and turning heavy bonsai constantly is also physically demanding. Bonsai turntables significantly simplify bonsai care. Options range from basic flat rotary discs to robust turntables that can be tilted and even vertically adjusted.
