Very effective

My small Cara Cara Orange tree had a persistent root weevil infection and was stunted most of the summer, with no new growth but just swollen leaf buds. A week after applying the nematodes the buds started to become small leaves and the tree was on its way to healing.

My veggie plants are super happy thriving on the ground treated with Clay and Hard Soil than common amendments for clay soil such as gymsum, peat moss and sand. Clay soil in Maryland is common and a gardener’s headache.

Clay and Hard Soil Kit

I J&B'd the poor soil (cut and grade development lot with a lot of clay) at my former house for over 10 years with great results and fantastic plant growth. In my new 85 year old house (30 miles from my former house) the soil was also poor with a lot more clay. I tilled and amended every inch of my new back yard and didn't find one single earth worm. I added J&B's and less than a year later the soil is full of worms and the texture has changed quite a bit. I also applied J&B's to the front yard (too large to till) with very good results! I'll be applying J&B's in April and every 6 months thereafter.
