PART 1 Here's my problem...Two dying cedars that were 15 feet tall or so, maybe 6 or 8 years old, have been treated like there was a bug problem. Decline was pretty severe over a 4 week time-span before treatment. When I talked to the client's daughter, she said her boyfriend had been washing his oil-soaked work jacket on the concrete next to the trees. I don't know what he was using as a soap or solvent if any. The trees are 85-90% brown but have new growth that is sporatic. Have any of you seen this and seen trees recover any more than this? PART 2 The client wants to remove the trees and replant. Should I remove some of the soil or will time leech the toxins through the soil enough to plant a few shrubs? Thanks for any input!
