Hi,

I'm a pharmacist and have some potassium nitrate in the pharmacy. Can
I use this next spring in my vegetable garden? If so, how much? Just
a small dusting and work it into the ground? Can or should I work it
in the ground now and let it sit all winter?

Thanks!!


Sure. Just look at it as fertilizer with 13.9% nitrogen and 38.7%
potassium. Don't put it in garden now as rainwater or snow will just
leach it into the ground where plants may not get it. In spring make
sure you balance with other elements like phosphorous or calcium that
vegetables may need.
