Raised bed soil and horse manure
I've just built two 4'x12', 12" deep, raised beds for vegetable gardening. I now need to fill these beds. I've considered using Mel's mix for these beds, but it's too costly. A local garden center has a mix of 60% loam and 40% organic compost for approx $27/yd. I called and asked if this is good for vegetable gardens, and the guy told me yes, but it isn't high in nutrients. I'm guessing this is from the breakdown of the organic materials?
A friend of mine owns horses, and has a manure pile and says I am welcome to take whatever I want. He has several piles, a fresh one, and an old pile from last year, I believe. This pile also contains hay, wood shavings, and paper shavings too. He also has a composted pile...but just used most of it for his gardens. Looks like I can have plenty of the older stuff if I want it.
Any advice on a good mixture for these beds would be greatly appreciated!
