Can I Use 12 12 12 On My Vegetable Garden?

The use of fertilizer depends on the crop, the condition of your soil and the growing season. If the plants are already growing, they can sometimes tell you what they need. 12-12-12 is just an indication of the ratio of the 3 Primary Nutrients (N-P-K) in the bag, as compared to other combinations. The only way to know what your soil needs relative to the crop requirements is to have a proper soil test done at a good nursery or your local agriculture extension service.

Indiscriminate use of fertilizer will do more harm than good.
