One of my neighbors complained that another neighbor killed a tree in front of her home by dumping paint in the soil. (Never mind that his trees are fine and there seems no way the paint could be transported from in front of his house to the soil under her tree. She's one of those neighbors.)
At any rate, I've "dumped" leftover paint (from cleaning water-based paint off of brushes and such) near trees from time to time and this got me wondering what sort of damage I might be doing to my trees.
Q. I know it's probably a bad idea, but will it kill my trees over time?
Note: Normally I send the runoff down the drain. My solvents and oil-based waste go directly to the recycling center.
