Trees and Shrubs : Watering
See more questions on Watering
I am wondering if you can tell me what is wrong with my Camellias.
Both are kept in containers in a shaded position outside my front door.
One of them looks like it is dying, is leaves have turned brown as have the flower buds and the new leave stalks. I'd there any way of saving this plant? What can I do too prevent it reoccurring? I have included photos below.
The second appears completely different, it is thriving with lots of new growth & a healthy leaf colour. However I've notice numerous amounts of small black insects under the leaves. There are also ants present. My initial treatment of this was to wipe the insects off which I did but more ahead each day. Is there a product I should use for better results?

This looks like root rot ... possibly just because it happens occasionally,
or possibly due to too much water and water-logging causing roots to die, which can be made worse by too little water, or no watering for a long period and then over-watering a plant already weakened.
