Review: Perfect addition for acid loving plants - If you have plants that need a lot of acid (in my case it's blueberries), you need to occasionally add some of this to the soil. It's easy to open, easy to distribute (just toss out on the ground around your plants), and nature will take care of the rest. Just take note of how much to distribute. My experience says that it's better to put too MUCH than too LITTLE.
Review: Works Great on my Hydrangeas, Gardenias, & Blueberries! - This has done a great job of brightening up the blue and purple tones of my various hydrangea flowers. It brought my gardenia to life - doubling the size and blooms on it. It greatly increased my blueberry yields and I swear it made them taste sweeter. I've been very pleased and have continued to use this.

## Questions & Answers

**Q: how to use on established hydrangeas ? And time of year to apply?**
A: Sprinkle around the base and out to the drip line in the spring and fall.

**Q: How do you apply it to your bushes**
A: Hello. The recommended amount per application depends on the bush's branch spread (the distance between the widest 2 points on the bush- from the tips of the branches on one side to the tips on the other). Use 1 1/2 Cups for bushes with up to a 3 ft branch spread. If the bush is 3 ft wide or larger, apply 2 Cups. Apply around the dripline and work into the soil. Water afterwards. Thank you.

**Q: Is this the same as dolomite and can it be used in earth boxes that request dolomite?**
A: Yes, this can be used in boxes requesting dolomite. No, this is not dolomite it is made from Calcium Carbonate.

**Q: Is this hydrated lime?**
A: This is garden lime, not hydrated lime. It's granular, not powder, and will not harm children or animals. It's not as caustic.

### ⭐⭐⭐⭐ Needed if growing blueberries on west coast
*by M***O on May 14, 2020*

Ok ordered couple bags of this acidifier. Jobes is a well knows brand for fertilizers and things so a trust worthy company when it comes to plants. My complaint and why one star is off? Well quality control of the bag itself. It looks like the bag wasn't sealed quite correctly, shifted about an inch over, so the one end had the edge stick out once inch farther, and the other side one inch shorter leaving the bag open on that side about an inch. If you know what this acidifier looks like is very tiny round flat particles. basically some of it was out of the bag and in the box. I guess that's what you get when everything is automated, there is no quality control anymore. If it was packed by hand someone should have caught this. It's not worth sending back, but i'm sure i'm out a cup of the material. Anyways, if you need to lower ph (acid) then use this, i think a few blue flowers and blue berries need this to grow in high ph areas like Los Angeles.
