RobinD said: I use hay bales to mulch my veggie garden....one year, I didn't use up one, so I left it to compost in the back of the garden....never smelled anything.....
luvsgrtdanes said: I don't know anything about using straw bales as a growing medium but I do compost all my goat hay and there is never any smell. My concern would be did they enter the property without permission...it's not up to them to dispose of something that is on someone else property. If they had a problem with something they should have contacted you or your aunt or even the authorities first.
