## Questions & Answers

**Q: does this get sprayed on foliage or ground?**
A: I use 1 scoop per 1 gallon water diluted directly to soil,If diluted to 1/3 scoop per gallon it can be used as a foliar feed (spray on). Remember to always foliar feed when sun is setting to avoid sun scald or nutrient burn. It works great!

**Q: How do you use this? For example Tbsp per gallon of water or so on?**
A: There is a measuring spoon in the container and so it's one measure per gallon, and my watering can is a 2 gallon so I use 2 spoon full

**Q: Does this have calcium to prevent BER?**
A: ITs in it...yes...>BUT IT DID NOT PREVENT BER on my plants...I added more Calcium Nitrate to my plants

**Q: Used for tomatoes or peppers, does it alter.. the color, acidity, or flavor?  using in ceramic container garden on deck..**
A: I have both ceramic and plastic pots for tomatoes.  Neither has taste changes when nourished with Jacks.
