I am a pharmacist and have a bottle of potassium nitrate. I figure I can just work it into the soil when I prepare my garden as fertilizer?? Or should I sprinkle it on the ground after the plants are growing.
I also have a bag of lawn starter fertilizer that has not been used in almost 10 years. I was going to throw it away, but wanted to know if that would work for a vegetable garden. Again, should I work it into the soil before planting?
Thanks
