As Richard said you have a fertilizer component that measures 50% potassium by weight.
However you should never fertilize with only one of the three. All should be represented in
each application. Keep in mind, that if you blend your 0-0 50 potassium with say, 0-45--0
phosphates in equal parts, you will not get 0-45-50, but 0-22(.5)-25 and if you also add nitrogen,
(which you should), the formula changes again in accordance of the proportions of the various
fertilizers in the blend.

Actually that is exactly, what I do: I buy each of the three in high concentration, in bulk and then
mix them as conditions, plants and seasons require. That is much more economical than using
'Miracle Green' or 'Wonder Grow' premixed formulas.

If in doubt, go to the store, look at the label recommended for your use and then employ your
math skills to come up with something similar. It does not have to be exact, just try to be in
the ball park. The plant will then pick up, what it needs.

There is just one thing to pay attention to: Overdose of nitrogen burns the roots.

Good luck,
Olaf
