## 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

**Q: Silly question, when it suggests 1 tablespoon per gallon of water or table per gallon of root ball?**
A: It means to use 1 tablespoon per gallon of water to use watering around the root ball area.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Just what I needed
*by R***R on April 11, 2025*

Item as described. Have not been able to use it yet because it won't stop raining. I'll get to it soon. I expect it will work as described as people have made great reviews on it.

### ⭐⭐⭐⭐⭐ Works as advertised
*by M***. on November 24, 2024*

Without this, my hydrangeas are pink. With this, the range from a purple to a dark blue. Easy to use.

### ⭐⭐⭐⭐ It needs to be in granule form!
*by J***N on April 26, 2024*

Just got this today, so don’t know how it works! But I do have a complaint, it’s solid as a rock in the container I need a sledge hammer to break it up not like the video where he just scoops the granules out!!!
