## Questions & Answers

**Q: Can this be used for propagation?**
A: not sure. used on azalea that was moved to a new spot in garden. I use "root tone" for cuttings.

**Q: Has anyone tried this for orchid root stimulation?**
A: I used this product on over twenty different genera of orchids from Cattyla, oncidiums, brassovolas, stanhopea, gongoras, cymbidiums, and plerialthallus, only one genus I had problems with was Hilaria. Following the directions, I used 3 tablespoons/gallon.

**Q: Mixing ? How are you guys doing it ? If one quart needs 19 gallons of water ? How is everyone mixing ?**
A: I use it largely on my newly planted annuals and  perennials so I use the cap from the bottle and add one capful to a gallon jug (clean milk carton) of water. Used it for years and that measurement seems to work well

**Q: Anyone used on lawn? i know other rgs  products are out there for that use**
A: I use when replanting items. I don’t know how it does on yards
