Chlorosis in R. arborescens
I planted a small R. arborescens in the late spring in a bed newly prepared by our landscaper. It had been lawn - he took the grass off and added top soil and I think some Biotone. I had him add extra peat moss.
Our soil is normally about ph 6. Pretty soon after the arborescens was planted the new leaves showed what I thought were classic signs of chlorosis - yellowing leaves and green veins. In July I added some Hollytone around the plant hoping that would help. It didn't seem to make a difference, but the plant hasn't put out new leaves since.
Today I noticed that the leaves were looking even more yellow so I'm worried. I have some "Color Me Blue" (to change Hydrangeas blue) which says it is a soil acidifier with "90% free sulfur from elemental sulfur." The inert ingredients are 8% Bentonite Clay and 2% Proprietary Wetting Agent. I'm wondering if I should add that to the soil now. There are three other Rhodies in that area that have leaves that look like they getting more yellow - though not with green veins.
I haven't had chlorosis before so not sure what to do.
