Hi Everyone

Have some Azaleas that are starting to yellow a little.
They had early signs of Azalea Lace bug, which I dealt with. I don't think
the yellowing is linked to the lace bug, as not all had the bug.
My only guess is the ground is too wet. Would this cause it?

The yellowing was first noticed about a week and 1/2 ago, and previous to
that we had about 2 weeks of drizzling rain, and the ground has been quite
wet. I gave them a dose of liquid fertiliser just to hopefully boost them
before spraying for the bugs.
Thanks for any help.


(From the book) Yellow leaves on azaleas are often from lime-induced
chlorosis, so have you been doing any concreting, or spread lime
anywhere else in the past 3 months? Maybe the rain washed it onto the
azaleas. The symptoms are yellowing of the new growth especially, with
the main veins often staying green (iron deficiency).

It also mentions phytophthora. The symptoms for that are leaves
yellowing on one branch first, leaf drop and dieback.

Mottled yellowing is probably due to lace bug.
