Pretty much all plants use roughly the same balance of macronutrients. The N-P-K three digit number identifies that balance in a fertilizer. Any plant uses the N and K in roughly the same proportions, but much less of P (middle number); plants often do quite well with only 10 to 20 percent P compared to the N and K. The good news is that as long as you provide the nutrients they need, it doesn't matter if you provide a little too much P relative to the other nutrients.
So, a balanced fertilizer with all of the 3 numbers about equal is a safe choice for just about everything.
