EM•1® Soil Treatment Guidelines:

Prepare the soil with lots of organic matter. On farms, we have growers applying 5-10 tons per acre per year. Compost, worm casting, or fermented food waste would work.

Spray soil till wet with a solution of 1 ounce EM•1® per gallon of water. You can use a hose end sprayer and set at 1oz per gallon. We are shooting for roughly 40 gallons per acre per year of Activated EM•1®. Generally, we suggest applying up to 3 gallons per acre per week of Activated EM•1 throughout the growing season.  Follow up with weekly foliar spraying as follows:

EM•1® Foliar Treatment Guidelines:

  • EM•1® foliar treatments are best applied in the morning before 10 am or in the early evening after 5pm.

  • A hose-end sprayer is recommended to use for application of the EM•1®. If a garden hose cannot access the garden a handheld or tank sprayer will work.

  • EM•1® can be added to water or foliar spray solutions that include liquid fertilizers, mineral supplements, or teas. Add the EM•1 ® to the spray solution just before application.

  • You can use 1oz per gallon to spray all landscape plantings.

  • For best results, spray at least once per week, but no more than once daily.
