Hibiscus Cooperi

[Judyarts]

I have a potted variagated Hibiscus Cooperi sitting in my summerhouse. The leaves keep going yellow or white and fall off. No sign of insects and its watered correctly..seems it is the temperature...any suggestions on how to save it. And what sort of feed would do it most good? Thanks

It sounds like a element deficiency of some sort. If the leaves that are falling is the new young growth it is probably iron or magnesium. If it is the older leaves it may need a feed high in nitrogen. Try giving them a liquid feed high in these elements and then give them a regular foliar feed every week or two.
