potato = Potassium ? ?

This is just an idea... A potato has alot of potassium in them so i wonder if if i was to get a few and soak them in a pot on the stove on low heat then let it cool if i could use the water in the pot to raise the potassium in my plants ? ? ? ? ?

No not at all.

Sorry bud but unfortunately no...Though potatoes are high in potassium the concentration compared to the overall size and serving of the potato, the concentration is actually pretty weak. Even a banana would not do suffice and banana are load with K! Sorry bud good thinking though.
