How to use horse manure for mulching.
I have a friend that has horses and I want to use some of the manure to mulch my garden before I plant this year. How much should I use and how long before I plant should I do it? I don't want to ruin the soil! I have not decided on the size of my garden as of yet a ratio by square foot as to how much would be most helpful.
While horse manure with bedding has the nutrient mix that is close to ideal for most garden vegetables, you might consider composting that manure and bedding mix. Composting can help reduce fly breeding in the manure and kill many weed seeds. See this publication:
