Question about complete fertilizers

19 years ago

My fall planting guide says to apply a complete (N-P-K) turf-grade fertilizer with a 3-1-2 or 4-1-2 ratio in Nov and Feb. What's interesting is I can rarely find this ratio in the big box stores. I can find all the starter fert or hi-nitrogen fert or any other number combo's I want, but usually not a 3-1-2 or 4-1-2 ratio.

Sometimes they'll get kinda close with the numbers, but it's not gonna be this straight ratio. Anyone have any idea why not. And what's the difference in a "turf-grade fertilizer" and the 40# bag of whatever with the same numbers??
