A concentrated blend of foundational soil-building and nutrient enhancing microbes and enzymes, in a dry powder form.

SKU: N/A Category:


Garden Hero’s Mother Culture contains a concentrated blend of foundational soil-building and nutrient enhancing microbes and enzymes, in a dry powder form. It also contains a complete food package to fuel these microbes and get them multiplying quickly. Simply put, these are the microbes that will help turn on the bio-life in your soil. That is why we call it the Mother Culture.

This product will improve soil structure and rooting, and will bring about more earthworms as well. Additionally, many of the microbes in the Mother Culture are also beneficial to the surface biology when sprayed foliarly on plant leaves.

It All Begins With the Soil


The best lawn and garden soils contain large amounts of diversified microbes that create humus, aerate, and improve soil structure. They release nutrients, promote deeper roots, fight fungus, and create environments where plants and grasses can thrive. Without these microbes you don’t have soil, you only have dirt.

Soils that are too clay-like or sandy are usually low in beneficial soil microbes. And soils that were once loaded with beneficial microbes and earthworms are often now nearly dead due to over-use of strong chemicals or harsh fertilizers, or perhaps due to acid rain. Our Mother Culture blend contains the ingredients that will resurrect the dormant microbes in your soil, and inoculate the ground with billions of new microbes (and a food supply) that will cause them to breed rapidly. It will even encourage earthworms to come into your yard. This is a highly concentrated product. One 2 oz bottle can cover up to an acre.

Greenhouse and field growers can add the Mother Culture to potting mixes, transplanting soils and even cuttings solutions to help kick start root growth and plant health.

Note: Though this is a stand-alone product, you will get better and faster results in the garden if you use it along with our Original Garden HERO. Initially, we wanted to put these microbes in all the Garden Hero products, but when we tried it the microbes immediately started to activate and the bottles blew up!

How to Use


(We have enclosed a scoop with the Mother Culture to help with smaller measurements. The scoop is 1 cc, or roughly 1/5 teaspoon.)

Garden Hero Mother Culture is in a powder form that can be mixed with water and sprayed on plants and soils. Just stir for about 15 seconds to get it into solution. It can be applied by itself or mixed with our Original Garden Hero or most liquid organic fertilizers.

Apply with a watering can, pump sprayer, hose-end sprayer, or any commercial spraying equipment every 1-4 weeks. Or simply mix a little in whenever you water or foliar spray your plants. Can be applied right over the top of existing plants. If spraying out of a large tank, make sure there is some agitation to prevent settling. Be sure to use up all of your solution within 24 hours.


  • 1 full pinch of Mother Culture per gallon of water.
  • scoop per 3 gallons of water.
  • 1 scoop – approximately 1/5th teaspoon per 1000 sf.
  • 1 Teaspoon per 5000 sf
  • 1 Tablespoon per 15,000
  • 1 oz (2 tbsp) per 30,000 sf
  • 1-2 oz per acre.

For initial applications you can double or triple these rates, especially if starting mid-season..

Water Quality. Many municipalities treat their water with chlorine in various forms. If you can fill your container with water and let it sit for an hour with the lid off, you will allow any free chlorine to dissipate/evaporate.

Tips. If you put in the Mother Culture into the water and let it sit for an hour or two with or without other products, it will start the microbes multiplying before you even spray. But don’t wait too long to apply. Try to spray it out any mix that contains the Mother Culture that day, or at most within 24 hours.
Note. Our Mother Culture contains some molasses and other carbohydrates that help feed the microbes. However, you can boost your results on both soil and foliar applications by adding some extra unsulphured molasses to the mix, or by spraying separately. Use 1 -2 oz per gallon of water.
