I have two crotons that were recently planted. One is in half day sun and is dropping some of the few leaves it has. I think they are davis hybrids- the unhappy one was sold to me by Mark Peters as a Davis #7 and is white/cream and green. I guess I thought these tolerated quite a bit of sun (like yellow and green crotons?). Do I need to put this in shade or will it just take some adapting? Thanks in advance.
