The only water I use is when I soak the roots with "Superthrive" and then I soak the roots with the apropiate "Mycorrhizae" then I use a mixture of gravel & akadama and plant it in a pre-bonsai pot of ceramic, never, never plastic or mica pots which for some reason or other doesn't work. Then keep the plant in the shade for a couple of weeks. In only one season the tree can be transplanted again if necessary.
