Repot every year and root prune hard, Wire when you need but do not let it cut in.
thru the summer months, remove larger leaves as needed, and if you wish to show, then total defoliate 2 = 3 weeks before hand to get a new flush of small leaves.
As bonsai, they rarely flower as they flower on the end of new growth so we always are cutting off the buds

the ramify really well and should be used more often as they are impossible to kill
