## Questions & Answers

**Q: The description says 4 lbs but it then says it comes in a 2 lb plastic bag and there is 1 item. Does that mean that there are two 2 lb bags?**
A: You will receive 1 order of 4 pounds in 2 two-pound bags

**Q: I saw one good review as was used on a mango tree. How did you apply it and what was the amount used in a litre or gallon of water?**
A: If being used as a fertilizer, mix one teaspoon to a gallon of water or keep that ratio for a larger area.  If a larger area use one lb per a 30 ft diameter circle and keep well watered. (Use at least 50 gal of water for initial application)  The chemical is very active and using with to little water can cause "burn" damage to plants.

**Q: I did not buy this for stump removal but because quote (designed for optimal plant nutrition ) need instructions for fertilizing our am  missing**
A: I got it for stump removal.

**Q: Can I mix 1 gallon at a time and give to I mid size tree? Meaning 1 gallon per tree..**
A: Be careful to use adequate water when mixing Potassium Nitrate as a fertilizer.  A good mixture is 8 oz of Potassium Nitrate in 100 gallons of water or 1 oz per 12 gallons.  Stronger solutions can damage plant life.   It doesn't take much Potassium Nitrate to feed a tree or other plants.  
You can mix 8 oz of Potassium Nitrate with enough water to make a one gallon of solution but that solutions should be used in a 100 to 1 injection hose sprayer for a proper application rate.  Hope that helps.  Skimp on the fertilizer and go max on the water.  It doesn't take much fertilizer to make a big difference.

*by J***S on March 27, 2022*

This is pure potassium nitrate. Works great for the pyrotechnics that I use it for and for this price is also a steal. I diy with my kids making sugar rockets, gunpowder, and numerous other projects they get off of TKOR on YouTube. So we go through plenty of this very quickly. Will make this my primary supplier from now on.
