I have 4 raised beds, 4'x8' each. I want to plant potatoes but need to know what would take the same/similar ph to be planted with them. I don't normally pay attention to ph but they did not do well last year. I usually just throw stuff out there and see what happens! So this year I think I should put a little more thought into it. I want to plant each bed with plants that get along. :) Any suggestions are welcome. Thanks!

Potatoes are just like tomatoes (first cousins) . They can grow in a wide pH range ( 5.5 to 6.8 ?) . But usually they(potato farmers) make potato soil more acidic( low pH about 6) that is just to prevent scabs not because of productivty or plant's health. Since you are not going to sell your crop, a few scabs is not going to matter much. Just grow them in the same pH range as you do tomatoes, peppers,..

What may affect potato productivity is POTASH for better tubing. So fertilize with a high "K" fertilizer.
