I don't know if this is the right forum for this, I had to dump some water after a heavy rain behind my hedges, there is an oak tree about 10 feet from where I dumped the water, it didn't hurt the grass or hedges, but the tree started dropping yellow leaves, like it was going into winter time, but I'm in Florida and it's July. Is it possible the tree roots picked up the pool water and is now reacting to it? Thanks for the help..
