I've been scared away from using our municipal compost because of a probable herbicide contamination a few years back. This is horse country here, but the possible aminopyrilide contamination is something I don't even want to think about, so adding manure for a soil amendment is also out. I don't have enough trees to provide me with enough leaves for working into the soil this fall; I can go rake up what I need at the county park. They do use Roundup around the base of the trees occasionally, and this year they sprayed a couple of areas with a weed killer of some sort to kill off the dandelions.
Would the tree leaves be OK to use - would the trees have sucked up the weed killer such that the leaves might be "toxic" to my garden?
