Raised bed soil, compost question
I am building raised beds after struggling with clay soil with lots of rocks for 5 years. I've decided to attempt SFG this year, if that makes a major difference in the soil choices.
I've read all sorts of threads on raised bed soil, and I'm thinking of going one of several ways. If I've understood what I've read completely, I could do one of the follow:
1) mix compost and soil in a ratio of anywhere from 50/50 to 25/75
2) Al's mix as detailed in an assortment of threads
3) A local vendor sells a raised bed mix that contains the following:
"80% of our screened compost mixed with sand, peat moss, rock phosphate and greensand"
Their compost is the following:
" farm animal manure, such as horse, chicken, cow, sheep, goat, and rabbit manures. These we gather along with whatever bedding material was used, such as sawdust, wood shavings or straw. We also mix in elephant, camel and other exotic manures from zoo........ fish scraps, shell fish, seaweed, paper, wood chips, spent bark mulch, wood ashes, mulch hay, flower, vegetable, and shrub trimmings and also food scraps. Our major bulking agent is leaves which we receive from local towns..."
Laziness makes me want to use the raised bed mix and be done with it. But, it is $80 a yard, plus delivery, which is a lot! (At least I think so. But, I'm cheap.) Alternatively, I could follow one of the plans above.
Any thoughts on their mix? I don't mind spending the money if seems good, because I'd rather spend the time planting than stirring dirt. Also, if anyone has other suggestions, I'd welcome those too. Thanks!
