To the group please help me. One of my Bougainvillea Bonsai is dying don't know why. I have shifted it in a bigger pot, have given it fertilizer. But not know what is going to happen. There are no leaves on it now, but if I peal the trunk a little there is slight green alive color inside. I don't know whether I have given more fertilizer or roots are too small to survive. I have this Bonsai from more than 1 and a half year!

Can you describe the way and frequency you water the tree?
