16974Re: [AZ] [this is from the ASK US page, so please send me a CC] - hardwood mulch put on azaleas by mistake
- Jul 1 10:10 AMAs the original question was about hardwood mulch, I have to repeat
what Don Voss told me: hardwood mulch is much more resistant to water
penetration than pine bark is, due to the formation of a fungus on it
(different than root rot fungus). I don't see a reason NOT to use pine
bark (or other more locally abundant non-hardwood mulches).
