Perhaps the city need to hire a better compost maker. I've learned with dismay that our city has to buy the compost from a central facility, and the city pays that facility to process our yard wastes! Anyway it is cheaper for the city not to have their own compost making facilities. The free compost are generally good and are weed, pathogen and insect free. If the yard wastes are not properly composted, like not achieving proper temperature, it could have pathogens, insects and weed seeds, like perhaps what happened in your city.
