Dennis,
Not sure where you got your NPK numbers for Tomato-tone, but here is a photo directly of the package:
I trialed Tomato-tone against other brands, and it outproduced the "other" tomato fertilizer, in my tests. Your results may vary.....
Regarding the cages, yes, you need to use the 4-leg model as they attach to the corners of the aeration bench perfectly. Take this Bar Code to Walmart (or Menards) to see if they carry them this year.
