Organic Liquid Bio-tiller

Penetrate is an organic liquid bio-tiller that contains powerful ingredients that work together to break up hard, clay soils. It works as a lawn aerator and a clay soil treatment. The live bacteria and other ingredients work together to break apart hard soil and allow air and moisture to circulate to plant roots. It improves drainage and turns hard clay into dark, crumbly soil that is easy to work with.

Back again

I have just this year, 2021 started to learn about John and Bobs products. And I am loving all of them. ********* is easy to measure, mix and spray. Could not think of a better product and I have tried several over the years.

An Impossible Garden's Salvation!

Superior products. My yard is the site of a burned-down hotel's parking lot. Unbelievably packed down rock and clay. Took 7 tons of dirt and almost 3 years of *********, but the transformation is amazing. Weak, suffering plants now thrive and my yard makes me smile, not cringe! I use all J&B products and recommend them to my neighbors. There is no comparison to living soil. Thank you for such great products! Eleanor
