Description

Lower soil pH to increase nutrient intake!

Alkaline soil can keep certain acid-loving plants from absorbing the nutrients they need to grow well. Blueberries require acidic soil, and so do other plants such as blue hydrangeas, cranberries, and lingonberries. This specially formulated mixture creates the perfect soil conditions for those plants to really grow.

Use Stark Soil Acidifier as directed, ideally prior to planting. One cup of soil acidifier covers one square yard of the planted area. For existing plants, sprinkle soil acidifier evenly over root zone and work into soil. Contains sulfur.

Works!
Works like a charm. The leaves started to look funny - brown spots and looking a bit sick. I added the soil acidifier and almost immediately the leaves looked better.

Acidifier review
I’ve used acidifier before planting blueberry bushes. It was only enough for one application for the area that I needed it for. It worked well.

Appears to make a difference!
Our blueberries went into the ground in early spring and now are growing well and look so healthy! I read reviews prior to purchasing the plants and the additional nutrients and decided the plants needed the best start I could provide. The extra investment should prove well worth it!

Good for desert soil.
I'm in the Arizona desert (where the soil is very alkaline), and you can easily tell the spots I've treated with this acidifier. They look so much better than the untreated things do. So I bought a heap of this stuff and have been using it since 2011.
