  • It improves the efficiency of compost, other nutrients, and fertilizers.
  • Our microbes naturally fight off disease and plant pathogens and help plants use water and nutrients (fertilizers) more efficiently.
  • Professional farmers have used this same proprietary mix of live microbes for years to reliably grow their organic crops

Just sprinkle, water and grow!

  • Use 1/4 teaspoon per plant or square foot of soil.
  • Shake directly onto soil surface at plant base and water generously or mix into soil before planting to get it to the root zone.

  • Use once a month, after heavy rains, or if plants are especially stressed.
  • Works alone and with most other garden products, but avoid bactericides and fungicides.

    Fast shipping, great product

    These guys are lightning-fast. I ordered from the east coast and they are on the west coast. I got an email about 4 hours after I ordered that my order had shipped. I got it a couple days later via normal mail. This product has more species than most competing microbes.
