On February 27, 2020, Darren Wong demonstrated for members of the Bay Area Satsuki Aikokai a technique for creating exposed root Satsuki azalea bonsai. The materials used for the demo included: Satsuki azalea cuttings, one four inch plastic nursery container, a plastic empty beverage bottle, small size Japanese Kanuma, medium size Japanese Kanuma, Japanese mountain moss (Yamagoke – Dried Japanese Mountain Moss for Surface Root Protection). Tools included: scissors, chopstick, #2 aluminum wire, wire cutters.
Step one was to cut the top off the plastic empty beverage bottle and make several large holes in the bottom of the container. It is best to have a plastic bottle that is narrower at the top and wider at the bottom. This is so the roots will grow within the container and be wider at the bottom than the top. Otherwise, the roots would grow evenly or worst in a reverse taper.
Step two, fill the four inch nursery container with medium
size Kanuma about half way up. The roots will grow through the bottom holes in
the beverage container in to the Kanuma.
Step three, attach the aluminum wire to the bottom of the
beverage container. Then insert the beverage container into the four inch
nursery container and wrap the wire around the nursery container in order to secure
Step four, prepare the Satsuki azalea cutting by removing
all potting soil and bare rooting the plant. Trim some of the foliage, if
needed. Do not trim any of the roots.
Step five was to insert the Satsuki azalea cutting roots into
the top of the beverage container. Then fill the beverage container with medium
Kanuma about ¾ of the way up. Top off the beverage container with small Kanuma.
Now fill the remaining portion of the four inch nursery container with the
medium Kanuma. Use a chopstick to remove any air pockets in the Kanuma.
Step six was to place the Japanese mountain moss on top of
the small Kanuma layer at the top of the beverage container to protect the root
On February 27, 2020, club president Bob Gould led the discussion on repotting Satsuki azalea bonsai. Bob brought to the monthly meeting of the Bay Area Satsuki Aikokai a number of Satsuki azaleas that were donated to the GSBF Bonsai Garden at Lake Merritt in Oakland, California. These were neglected plants in various containers with potting soil. The task at hand was to eliminate the potting soil and repot the plants in 100% Kanuma bonsai aggregate.
The immediate undertaking was to eliminate the potting soil and bare root the azalea plants. The potting soil had broken down and causing problems for the plants. The use of chopsticks to pick away at the potting soil was found to be most useful for this task. Once the potting soil was removed, then the plants could be wired in to containers on hand and filled with 100% Kanuma (a preferred bonsai aggregate for Sutsuki azaleas).
Japanese Kanuma is the perfect soil for acid loving plants. The most common plant to utilize Kanuma for bonsai is azaleas. Azaleas along with Camellias, Gardenias and other acid loving bonsaican be potting into pure Kanuma. Kanuma is a very light volcanic rock.
The evening produced a number of repotted Satsuki azalea bonsai. Time will tell whether or not these plants will be developed in to bonsai.
