## Questions & Answers

**Q: Your descriuption is completely wrong for this product! It sounds like the description for a hose!**
A: Yes, this looks like the wrong info for this product. The product is great, but it is for Hydrangea flowers, this is not a garden tool.

**Q: Will this turn pink hydrangeas blue?**
A: I used it late winter early spring and every flower is now blue-purple.  I just noticed in mid July pink flowers are coming again so I will add some more

**Q: Is this good for bigleaf hydrangeas?**
A: I guess I don’t Know the difference. But I would expect it to be good for hydrangeas in general🤷🏼‍♀️
Sorry I can’t be of more help to a fellow gardner

A: It means to use 1 tablespoon per gallon of water to use watering around the root ball area.
