## Questions & Answers

**Q: Is this safe to use around honey bees?**
A: Yes! Just water tomato like normal with it and no harm to anything including bees.

**Q: Can you just mix this with the water in a watering can and pour it on the base of your plants saturating the soil?**
A: You can mix it in a watering can (I used a pump sprayer), but it must be applied to the leaves and fruit.  It does not get absorbed through the roots.

**Q: If I bought this last year is it still good this year?  Does it expire?**
A: I bought mine last year as well, and I am using again this year, and it seems fine and is still working. I do not believe it expires...but if it does, it would indicate it on the container somewhere.

**Q: After mixing how long will it last??**
A: Use within 12 hours then mix more if necessary
