Today's video we take an indepth look on how to build a slab pot for your bonsai and how to make a Japanese maple bonsai forest.

with a step to step guide any one can make a nice look slab for their bonsai. this video will teach you everything you need to know.

and these are mot just any slab pot and no need for a kiln. and when correctly followed and weather resistant to. they may be a little heavier than ceramic pots but are still manageable to move around easily (the bigger they are the heavier they will get)

now with the Japanese maples selected are Japanese mountain maples and we have chosen 7 of them for this video.

when building a bonsai Forest its best to build to a natural flow. having trees growing together but away from each other giving the appearance that they are competing with the light.

trees with a curve in the trunk I have found to be more suitable for the sides and back as they are growing on the edge of a forest competing with its brothers and sisters.

with the soil we can't use the usual soil we use for bonsai as the slab has nothing to hold it all in place and would easily wash away when watering. so we are using John inns no2 soil that has proven to work well. but as its not at free draining it would mean to water less often but still can't be left to dry out.


Creating a Japanese Maple bonsai forest on a slab pot is a wonderful project. Ensure proper soil, spacing, and pruning for each tree. Consider varying heights and angles for visual interest. Regular care, including watering and fertilizing, will help your bonsai forest thrive.

Arrange the trees on to the slab with attention to aesthetic balance, using odd numbers for a natural look. Secure the trees with wire to the slab, allowing for growth. Trim branches to maintain the forest illusion, and use moss to enhance the realistic landscape effect. Regularly check for pests and diseases to keep your bonsai healthy.


As your bonsai forest develops, pay attention to seasonal changes. Adjust watering and fertilization based on the specific needs of each tree. During autumn, embrace the vibrant colors of the Japanese Maple leaves, and consider thinning some branches to maintain balance and airflow. Additionally, periodically rotate the slab to ensure even sunlight exposure for all trees. Patience is key in bonsai cultivation, allowing the forest to evolve gradually into a captivating miniature landscape.


To enhance the visual appeal of your Japanese Maple bonsai forest, consider incorporating small accent plants, rocks, or miniature figurines strategically on the slab. This can add a sense of scale and create a more natural scene. Be mindful of the overall composition, aiming for harmony and coherence. Regularly inspect the root system, adjusting as needed to prevent overcrowding. Remember, the art of bonsai lies in the ongoing care

Watering: Ensure the soil is consistently moist but not waterlogged. Water thoroughly when the topsoil feels slightly dry. Adjust the frequency based on the season – more in hot months, less in winter.

Soil: Use well-draining bonsai soil to prevent water stagnation. Repot every 2-3 years to refresh the soil if needed.

Fertilization: Feed your bonsai with a balanced granular fertilizer during the growing season (spring through early autumn). stop fertilizing in winter.

Sunlight: Japanese Maples prefer partial shade, especially during the hottest part of the day. Provide filtered sunlight to prevent leaf scorch.

Pruning: Regularly prune to maintain the desired shape and size. Pinch back new growth to encourage branching, and remove any unhealthy or crossing branches.

Wiring: Use gentle wiring to shape branches. Be cautious not to leave wires on for too long, as the tree can quickly grow and cut into the bark.

Pests and Diseases: Monitor for pests like aphids or spider mites. Treat promptly with insecticidal soap or neem oil. Keep an eye out for signs of diseases and address them promptly.

Winter Care: Protect your bonsai from extreme cold winds. Consider moving it to a sheltered location.

Remember, each tree in your bonsai forest may have slightly different needs, so observe them individually and adjust care accordingly. Regular attention and care will ensure the long-term health and beauty of your Japanese Maple bonsai forest.
