Review: It works for my Brazilian Jasmine - I used ferrous sulfate on my plants when they were on the verge of dying, and the results were amazing! After applying it, the plants came back to life with vibrant, healthy leaves, and flowers in about two weeks. It truly revived them and is now a key part of my plant care routine. However, one thing to be cautious about is that it can leave stains on the floor or nearby surfaces, so it's important to apply it carefully or place something underneath to catch any drips.

## Questions & Answers

**Q: why does this say 20 percent iron? is it still 100% FeSO4?**
A: The molar mass of the compound (ferrous sulfate hepthydrate) is about 278 g/mol.  The molar mass of iron is about 56.  56/278 = 20% iron and 80% everything else.

**Q: Is this the same ingredients  as copperas**
A: Ignore the other guy. Copperas = Iron sulfate

**Q: Is this product good for acidifying soil for blueberries?**
A: There are better products. Some iron (within reason) helps green up most plants, but the ferrous iron is a reductant, more like a weak base (sorta) than an acid. To acidify, use (dilute!) sulfuric or phosphoric acid, mono- or dibasic potassium phosphate, or elemental sulfur.

**Q: will this product control moss in a flower garden without significantly affecting the PH of the soil?**
A: no. this will lower the pH slightly. also i think you are referring to algae, which grows as a result of compaction and too much water.

### ⭐⭐⭐⭐⭐ Magnificent Magnolia
*by P***Y on May 29, 2023*

After years of drought my Magnolia was suffering from lack of acidic rain and iron. I augered holes 18”-24” apart around the drip line and put a couple-three tablespoons in each hole and within 10 days the tree was coming back to vigor.
