Unhappy Camelia

They do like very acid soil so that shouldn't be a problem but not many plants like saturated ground. I don't think they like it too windy either. You could check the situation of other local camellias. They can take a while to establish. I planted one about 10 years ago (the position is not as acidic as they like though) and it didn't do much till last year when it had one flower. This year is has lots of blooms on it - as has another near by that was planted about 4 years ago.
