True OrganicSoil Acidifier – Lowers Soil pH for Acid-Loving Plants – Ideal for Turning Hydrangeas Blue – 6lb Bag

this really helped my indoor plants this December. they grew and turned green . What my indoor tree's really needed. However if you have kittens watch your ferns they'll take up residence in the bowls. Mine are still struggling but survived thank to this with all the nutrients.

I was sold soil that was too basic. This acidifier dropped the PH exactly where I wanted it. I went from 7.5 to 5.5 on the pH scale exactly where I need it for blueberries.

After a few months of using the acidity soil, my blueberries are very healthy.

Made a lot of difference when I added this to my plants.

Best stuff for the price. My berry bushes and tomatoes took off.

Purchased this to my wake my soil perfect for my blueberries. It must be working. My bushes have lots of blueberries in them right now.

Struggled to lower PH sufficiently for blueberries using this product. Learned that a small amount of vinegar mixed with water worked better. Maybe a combination of both better for short and long term PH maintenance? VERY possibly user error. Maybe blueberries are especially difficult application?

It's very useful. It's a little light purple.
