Japanese Stewartia


Japanese Stewartia: The Japanese Stewartia (Stewartia pseudocamellia) is a deciduous flowering tree native to Japan. It will produce gorgeous white and fragrant bell-shaped flowers in the summer and is highly regarded for its red exfoliating bark when bare in the winter. . In the fall, the leaves display stunning scarlet and purple colour before they fall. As a Bonsai, it is very forgiving, hardy and tolerant. This is an outdoor Bonsai and is dormant in the winter. 


Japanese Stewartia can be placed in full sun and will also tolerate shade. 


  1. Japanese Stewartia like well-draining soil that is left to dry. During warmer days with plenty of sun, watering daily is recommended. 
  2. Japanese Stewartia needs to be winterized during the winter, and the soil should be kept minimally moist. 

  • Training: Japanese Stewartia take well to directional pruning and can be wired in fall throughout the winter. Having alternating buds makes this a genuinely great Bonsai to develop good ramification. 

  • Repotting: young Japanese Stewartia requires repotting every other year. Mature Japanese Stewartia can be repotted every 3-5 years. 


BABY: 10"-16" tall, comes in a 4" grower's pot. 

YOUNG: 12"-24" tall, comes in a 6" grower's pot.

Soil (Substrate)

Bonsai soils are usually a mixture of organic potting compost (Pine Bark or Forest Floor), Akadamapumice, lava rock in varying amounts. 

It is important for the soil have good water retention while also draining well, along with very good aeration. The quality of the soil directly affects the health, size and growth of your tree. One of the worst things you can do to your tree is plant it in regular garden soil. Garden soil hardens when it drys and can often lead to a disadvantage when growing a Bonsai. 

Soil mixtures can be purchased here, but given their weight and cost of shipping, you can also easily make your own. 


Depending on the type of Bonsai you're growing, here are the general formulas for successful mixtures. 

Deciduous Tree (Leafy and looses leafs in the fall)

50% Akadama

20% Pumice

20% Lava Rock

10% Potting Compost


Coniferous Tree (Evergreen like Juniper, Cedar)

1/3 Akadama

1/3 Pumice

1/3 Lava Rock


If you are not able to check on your Bonsai's moisture levels daily, add more Akadama to the mix. 

Given how these soils erode over time, repotting every 2-3 years is required. 


Here are some suitable replacements if you cannot find the recommended types of soil.

  • Akadama - fine fired or baked clays, some even recommend cat litter as a substitute. 
  • Pumice - fine crushed aggregates, expanded shale and vermiculite.
  • Lava Rock - This can be replaced with fine gravel or you can also look into purchasing a larger lava rock at a hardware or gardening centre and crushing it. 



One of the best and easiest ways to fertilize your Bonsai, is to add a liquid fertilizer mix when water your Bonsai's once a month during the spring/summer. If your Bonsai looses leaves in the winter there is no need to fertilize it then. If you have a coniferous tree, fertilizing the tree once in the beginning of winter and once in the middle of winter should be sufficient.
