Review: Good for blueberries - I use this every fall and spring on my blueberries to acidify the soil and fertilize them, and it seems to be working great. Been doing it for about 3 years now, and getting better crops than I used to.
Review: Good product ai instructions for safety - If you have ai available always double check the math on how much to add. The amount they say to give a 16" pot is correct math but incorrect science and will likely kill your plants. 4 tablespoons not a cup and a half. Anyways, the product is good and I always double check instructions and dont hold mistakes against the companies for bad translations. 👇🤗 Espoma Soil Acidifier uses the same container rule: 1 Tbsp per 4" of pot diameter. Same math: a 16" pot gets 4 Tbsp, not 1½ cups.52b09e Espoma The 1½-cup in-ground rates you see online (1¼ cups for a new blueberry/hydrangea, 2½ cups for an established one) are for plants in the ground, spread out to the drip line — not for mixing into a pot.596e4d assets.unilogcorp So yes: the 16" pot measurement on the bag is high compared with the manufacturer’s own container directions. 1½ cups in a pot is roughly a full landscape plant dose stuffed into a container. Vibe-garden version for pots: 4" pot: about 1 Tbsp (bag’s 1½ Tbsp is close enough) 16" pot: 4 Tbsp (¼ cup), not 1½ cups Blueberries / hydrangeas: you can go a little over that ¼ cup if you want, still stay under ½ cup

## 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.

### ⭐⭐⭐⭐ Product is fine packaging not so much.
*by G***Z on July 31, 2026*

It came in a box with a couple pairs of scissors and there was a hole in the fertilizer bag so the fertilizer got all over everything, otherwise fine - still not happy about it.
