Rhododenrons about 5 years old, I have one on each side of the porch. Purple flowers. This was the better one of the two. Last week I resprayed/painted my bathroom lights with RustOleum 'hammered' spray paint, as they had gotten rusty from the shower. It was raining that day (as it is every other day this spring), so I did it off the porch. Flecks of the silver paint got on the leaves of the plant, unnoticed. What I did notice, is the plant started dying shortly afterwards. I don't see any other evidence of what could be causing it, rains have been frequent and no freezing weather, the bush on the other side is doing fine. I spent the whole night yesterday looking up silvery spots on the leaves, only to come to the realization this morning in the daylight, that these aren't spots. They're specks of silver paint from spray painting off the porch. Could it have absorbed the chemicals, is this killing the plant? Sure looks like it. Is it too late. What to do??
