Also if you get mulch from an outside source you don't know what insects, pesticides, herbicides, etc. are in it so making your own or using manure is usually better.
To be clear I was asking for advice on where to get quality mulch (not compost) from not how to make it (obviously by giving my general location I was looking for somewhere to go)... I am looking for people’s advice on where they are getting their’s in my area. They would already have the experience and could tell me things like why they choose a place. I would then have knowledge as to what was going into it, or could investigate it myself.
Using horse manure sounds ok except how am I supposed to know that there aren’t medications or chemicals going into that as well seems like the same origination issue. Most manure is mixed with the bedding, do you know exactly what chemicals were used on the hay? Or paper? Or wood shavings? Not too mention the E. coli and other pathogens in horse manure. Frankly I am aware that horse manure in particular is significantly more prone to introduce weeds vs cow manure (it has it’s own negatives). Along with the fact that I would have to add in Phosphorus and Potassium from other sources as horse manure is low in these. My preference would be to stick to native woods, leaves... etc and add my own nitrogen sources from my food waste, if need be for when I need compost. But I don’t, I need mulch.
