Hydrangea murder mystery
We planted a row of hydrangeas 3 weeks ago. They all get about same sun (the ones on the left just a tad bit more), they get the same water (again, a little more for the ones on the left because they get a bit more sun), there are cedar trees at both ends.
Within 10 days they looked like the photo attached: as you can see it looks like someone took a torch to the ones on the left and the effect tapers off at plant #3.
They were all planted the same way in Cedar Grove Compost mixed with Dr. Earth's Organic Fertilizer.
Is there something in the soil that might be causing this?
Thanks for any insight/guesses you can provide.
