What nobody has mentioned is that if the yard did have a fire in the mulch pile from not enough turning, that there is some toxic byproduct from the fire that will kill plants.
Had it happen several years ago by us. Local nursery had a fire in their pile, didn't get the burnt stuff out, sold the mulch, had a bunch of plants die, etc. Spoke with their supplier at the end of the year and discussed this. The nursery was blaming the supplier, but didn't happen to mention the fire. When we mentioned it to the supplier, the light went on. Not sure how that one turned out.
Never had a problem with the steaming mulch before. I've applied in all temps from snow to 90*+ and haven't had an issue. The 90*+ is why we use a sub with a blower truck.
