>>>> I'm hoping the trees under the lines are safer than regular homeowner trees, because they are on the right of way, meaning nobody is spraying anything there.
Cindi ... That's my working assumption, too.
I can't let it age for a year, so I use it as a top mulch to my leaf mulch. I screen out the larger pieces and use those for starting my winter fires, so I am usually putting down smaller chips and they decompose faster over the leaf mulch.
>>>>Most around here are elm, cottonwood or cedar, so those are good for mulch.
I read somewhere that cedar is not good to use for mulch, but I can't remember why. If you haven't had any problems, it's not an issue. We have black and white oak, fir and pine that gets chipped. I've been using those wood chips for years and haven't had any problems.
A friend of mine got a load of chips from a tree trimmer that worked on homes up here, and almost lost most of her garden. Who knows what those homeowners put on their trees ?
I get the leaves for my mulch from a friend's property. I know she doesn't use anything that would cause a problem. She has told me that I am too cautious, but it's stories like yours that make me cautious.
