EM-1® and TreesUpdated a year ago

We recommend applying 25 gallons per acre per year for trees. It is best to divide this amount out as much as possible. Most farms irrigate on a 10-day cycle. Therefore, we have people spread the 25 gallons per acre out by each irrigation.

We also recommend an additional 15 gallons per acre, in a foliar mix, over the season.

If you are not irrigating, you can do a tank mix and drench as well. It is ok to mix fertilizers in the tank as you are watering. The microbes will survive in the water for up to 4 hours. Therefore, do not store fertilizers and activated EM-1 in the same tank for an extended period of time.
