Ratio Of Manure To Top Soil For Planting New Shrubs And Plants.

Question

We are building raised beds for shrubs and plants and would like to put in manure and top soil. Any advice on ratio of manure to top soil.

Answer 1

I see 30 to 40 pounds of composted manure for every 100 square feet of soil in several extension publications. Also you can spread 1 to 3 inches on top of the soil and work in about 6 inches. Here are more recommendations:
