    I have been using Kelp/Humic Blend for a number of years now as both foliar spray and a drench and none of my plants, be veggies or herbs, have any micro nutrient issues, and my seedlings start quicker and stronger than without.

  2. NJMike

    I have been using this type of blend since 1987. This combination product has been a proven success with arborists and lawn care companies. It is a great way to feed the soil and produce healthy root systems. This is my go to organic product every year.
