Can you help this camellia?
Here is a picture of my very old (at least 50 years, possibly more) camellia. It is blooming OK, but the leaves are very yellowish. Last year after it bloomed I did feed it with acid plant food - what else can I do? It used to grow under a very large tree, which got cut down last year. However, it had yellowish leaves before that, too. Any suggestions would be very welcome! (also any guesses as to who it is).
