Thank you for your replies. I would say yes, the left side of the house may get more sunlight during the day but for both sides after 1:30pm both sides are shaded but the right side more than the left. We used the root stimulator when planted and have used a slow release fertilizer only once (last month I believe).....both plants we treated the same. we moved the rock from around the left side ones to look a the draining and they are all planted on a slope so the water is almost running off of the soil when I water....so they are not "sitting" in water if that makes sense. When planted we mixed in some of the existing soil with top soil and start and grow fertilizer in the soil.
I am uncertain how to test the soil.....
In addition on this same side of the house (left side) we planted 5 encore azalea plants - four of them look wonderful and have grown a lot and one well not so much.
Also, we planted a Camelia in the corner and all of the leaves are now falling off of it.
We are definitely not plant experts as you can see......
