Question
The leaves on my camellia plants are turning very yellow, not the dark green shiny leaves they should be and the flowers are turning brown. Can you help.

Answer
If the bushes has been planted for a year or two, I would be suspicious of a nutrient or other environmental stress.  Also, examine the bases of the plants for any physical damage to the main stem. If you wish, you can send me a photo of the leaves.
