The Lactic Acid Bacteria (LAB) that we carry is yet another amazing product by  Country Roots Ltd. We are proud to offer this high quality, consistent and small-batch crafted product from a family-run business here in the Midwest (Northern Michigan).

What Are Lactic Acid Bacteria (LAB)?

Lactic Acid Bacteria (LAB) refers to a group of bacteria that produce lactic acid from the consumption and digestion of carbohydrates and sugars. When the lactid acid accumulates, they ferment the carbohydrate source (or pickle the food). LAB are used in the production of yogurt, kimchee, sauerkraut and many other nutritious, probiotic food sources.

In horticulture, adding LAB to your soil drenches effectively loosens and conditions your soil to help prevent anerobic conditions from arising. When used as a foliar spray, it has been shown to provide protection against fungal pathogens such as powdery mildew. 

 Note About Gallon and Bigger Orders: Please allow 1-2 weeks as we generally will make new batches of LABs on bigger orders to ensure quality, freshness and biological viability. If you are concerned about timing, please reach out prior to placing an order to ensure we can meet your needs.

We encourage everyone to read more on the amazing product that is LAB and understand the process of making it. Learn more from this amazing publication and guide from the University of Hawaii on Natural Farming: Lactic Acid Bacteria

Benefits of LAB

Lactic Acid Bacteria is used in natural farming as a way to aerate soils, encourage decomposition and enhance plant health and defenses.


When applied as a foliar, LAB can be effective at preventing negative fungal pathogens like powdery mildew.

LAB can be added to plant nutrient solutions like Fermented Plant Juice and applied as well.

We have found LAB helps us reduce the need for other foliar sprays that can be more damaging to beneficial members of the ecosystem.

Root Drench:

LAB can help at loosening and aerating soil to reduce anerobic pockets. It can accelerate the decomposition of organic top dresses/amendments and expedite the nutrient cycle for quicker bio-availability.

Seed Starter:

LAB along with other natural farming solutions can be applied to seeds to improve germination and deter fungal issues by inoculating the seed with beneficial microbes.

Directions for Use

Application Rate:

In foliar and soil drench applications, LAB should be diluted to 1:1000 with non chlorinated water.

It is not recommended to use LAB late in flower as a foliar or root drench. LAB use should cease mid flower by week 4-5.


Store with cap on in a cool, dry area.
