my hibiscus tree is in a pot, outside with alot of sun and I water this plant everyday....A lot of the leaves have yellow spots, then they completely turn yellow. I have taken them off the plant when this happens but more seem to come. The plant does have many flowers, but the leaves are now bare......I purchased two hibiscus trees at the same time and one is beautiful and full and then there is this one.....
I did fertilize once with miracle grow - rose plant food.....
