Ficus microcarpa, seed grown, in the sprout or clump style
While there are many ways to sprout seed I am currently sprouting my fig seed by sowing the seed on the surface of rock wool plugs. These plugs are available online or from garden centers.
The plug is kept in a shallow dish with a bit of water in the dish. This keeps the plug from drying out. Ficus seed take somewhere from 1-12 weeks to sprout or even longer. Plants are kept growing on this plug until they have 4-5 leaves on each sprout.
Once the seed has sprouted and two or three leaves have appeared the plugs can be placed into a bonsai soil mix. The surface of the plug should be 1/4-1/2 inch above the surrounding soil mix and allowed to grow for a year. Once the seedlings are quite sturdy with about 8 leaves on each one they can easily be removed from the plug and rooted into a pot of bonsai soil.
It normally takes 3-4 years from seed to get a plant large enough to begin bonsai training, so the process is not for the impatient bonsai grower.

I was unable to find Ficus tremula for sale in the US so I am resorting to growing them from seed. It will take many years for these now two month old seedlings to mature into a reasonable bonsai. Growing from seed is for the young and those with lots of patience.

Leaves are large but reduce with defoliation. There is some random branch die back suggesting that this may not make the best bonsai subject.
The bark is a rather stark whitish brown.
