What our Customers have to say

Several years ago I picked up a brochure on your soil. As I was reading through the small pamphlet I liked what it said. Organic, no chemical additives, decreased mineral leaching, helps to break up tight clay soil and adds organic matter to sandy soil. Chemical, pathogen and weed free. Very important to me was the line that read “Safe for children and pets.” For the last three years I have used Humalfa almost exclusively instead of chemical fertilizers. I have been very pleased with the results. My grass and flowers and bushes are doing very well. I use Humalfa in the spring as a top dressing in my
perennial beds and in areas where the Marigolds and 4 o’clocks come back from seed. I believe the Humalfa provides what my plants need and I feel much safer working with Humalfa than I do with any other fertilizer.

Just a note to let you know that my lawn looks the best it has in years thanks to your Nature’s Prescription organic fertilizer! My SE Denver soil is full of clay which makes it hard to maintain a healthy lawn. This year I noticed that our lawn has been full and greener with less watering! Looking forward to a spring application.
