For acid-loving plants

If you're growing blueberries or other acid-loving plants like Hydrangeas, a little soil acidifier will help them grow very well. Hydrangeas will turn to a blue color in acidic soil, otherwise they will remain pink. Blueberries won't survive in alkaline soil.

Bring Us The 30lb Bags

Excellent value and price. You cannot find this size bag cheaper anywhere else, I would love if you could also carry the 30lb bags as I have to buy so much of this for my hydrangea garden.

True blue

Kinda dusty, but the Wife likes her hydrangeas to be blue (not pink). This stuff keeps her happy. Happy wife = happy life. Basically just adding to stuff to order to get "free" shipping.
