    The solubility of the product is decent however there is sediment left over in my sprayers and reservoirs. I believe it’s the humic or seakelp. I will say the product works extremely well with my plants even at a diluted ratio of 5ml instead of the suggested 15ml a gallon. Growth of roots, stems, and shoots is phenomenal.
    Either way the product works well and I would suggest it. It has a higher cfu than most products on the market

    We started using Diehard Biorush over a year ago with all of our new plantings. Out goal was to encourage a healthy start for the newly transplanted plants and reduce call back and replacements. We have already seen a significant reduction in both and there is a significant improvement in the plant establishment.

    We have been using Biorush for over a year and have seen tremendous results. We’ve had newly installed sod that had irrigation unknowingly cut off that were we able to revive by spraying with Biorush. We’ve had a large roof top tree that was craned up during construction and could not be replaced that had the irrigation cut off during some waterproofing repair and we were not made aware. We noticed the tree was in stress a couple of weeks later. We stripped the leaves and treated with Biorush and it survived. That would have been a major problem if it had died. I would highly recommend using Biorush.

    Die-Hard Bio-Rush is an excellent additive. Your plants will love it! I can’t say enough about this product. Bio-Rush will PROTECT your plants from a host of bad fungi. I used to have a powdery mildew problem. I tried everything on the market to get rid of it! From sulphur to potassium bi-carbonate and every fungicide known to man. I had all but given up when I discovered Trichoderma beneficial fungi. After using it regularly my mildew disappeared. I HIGHLY recommend this product, your plants will thank you.
