Bone meal provides phosphorous (in your 3-number sequence, the middle number). Blood meal provides the first number, nitrogen and Epsom salts is magnesium and do not apply unless you know you need it. It would be best to have your soil analyzed before making that decision. I find alfalfa meal and cottonseed meal a good alternative to anything else, just as a practical, all-around treatment for my plants. I do add bone meal to bulbs, etc. When planting roses, I use triple-superphosphate which gives me a big bone meal bang.

Search soil amendments and fertilizer. Check out the Organic forum. Try Bulbtone or Plantone fertilizer- organic, but pre-packaged. Bulbtone has more phosphorus- good for roots and flowers. Nitrogen aids green leafy growth. Corn meal is supposed to help feed the good bacteria in the soil and adds slow release nitrogen. There's several threads on this in the organic forum.

Cornmeal works,the earthworms like it to but use plan meal I use one cup per 1' hight of bush Ep-salt 2tbl spoons in the spring per bush,bonemeal as needed.good luck JIM

epsum salts will help cause branching (according to our local ag. agent) I use it on my roses in spring and it helps keep my Gardenias green, I give them 1 tblsp per foot of height each spring.
