Ferrous Sulfate Heptahydrate - FeSO4*7H2O - 20% Iron - Very Soluble - 1 Pound

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.

Easily dissolves in cold or warm water. Packaging is strong and durable. Did not precipitate out of solution at 5gram per liter. Very pleased.

Works great for my eco printing projects.

The solution must be strong to work at all. For example, 2 oz per gallon it took weak. 6 to 8 oz per gallon is better. When strong, moss turns dark in an hour. I just did that today. Hopefully the moss will die. When the solution is weak it takes 4 hours or longer to turn dark and the moss just grows back. Fingers crossed. Also, the moss needs to be thoroughly wet. Just a quick hit won't work.I am trying to slow the moss growth down so a granulated iron sulfate will work better. Complete lawn coverage with a sprayer is difficult and takes several passes. Moss killer granules often have some fertilizer to help get grass growing. Granules goes through thick moss and doesn't work well unless it can stick on top.

My plants needed a boost and easy to use this did the trick great value for my money

My trees were iron deficient and the leaves were yellow. Stuck a few scoops of this in my inline sprayer and hit the trees with the hose. 1 week later i have green trees again. Though the mist stained my cement brown in places... but that's on me.

I purchased this for use in Natural dyeing had to use 5x the weight of powder to get effect I am used to making this a very expensive waste of money. As noted in other reviews, this is a very impure product. MSDS sheet is misleading.

No instruction of how to use. I just add small amount in one gallon of water and water the plants. Do not water above the leaves, it burns really bad. Water around the soil only. I used only once combined with fish emulsion. After a few weeks, new leaves look much healthier and happier. Probably won’t need it again for months or even a year.
