Which number is phosphorus in fertilizer is one of the most common questions new gardeners ask, and the answer is simple: it is always the second number in the NPK ratio printed on every fertilizer label. Knowing what that middle number means, and how to read the full label around it, changes how confidently you choose and apply fertilizer.

Understanding NPK fertilizer ratios and proper application timing helps gardeners choose the right nutrition for vegetables, flowers, and lawns.
