Question
my camellia (Margaret Davis)is developing discolored leaves.  they look slightly yellow and patchy.  I have been feeding with erecacious feed.  It flowered as normal, although the weather caused the buds to rot due to the rain.

Answer
Diane,

It sounds like the wet spring has brought on a leaf blight of leaf spot disease. I would recommend using a fungicide to minimize the damage to the plants.

Continue feeding and monitor the plant for insect activity.

Good luck,
