You can mix your own organic fertilizer by choosing one element from each of the categories below and mixing them together to produce a general fertilizer. Doing so will give you a balanced product containing Nitrogen, Phosphorus and Potassium:
(N) 2 parts blood meal or 3 parts fish meal
(P) 3 parts bonemeal or 6 parts rock phosphate
(K) 1 part kelp meal or 6 parts greensand
