Fermented foliar extracts are made by finely chopping leaves from plants like comfrey or nettles and layering them with brown sugar in a container. The material is weighted down for 24 hours before being covered and fermented in the dark at 65-70 degrees Fahrenheit for a week. After a week, the brown syrupy liquid that has accumulated is drained off and can be diluted and used as a nutrient-rich foliar spray for plants.

1. Fermented foliar extracts contain nutrients
and growth factors beneficial to growing
plants.

2. We harvest, before dawn, the fast-growing
leaves of plants such as comfrey, stinging
nettle, mugwort, or vegetables, and weigh,
but DO NOT WASH, the leaves.

3. The vegetation is finely chopped...

4. ...and layered with an equal (or up to 2/3
greater) weight of brown sugar in a clean
crock or bucket.

5. The material is then weighted down with a
weight or “press” (a plastic garbage bag
partially filled with water), to ensure even
coverage, and exclusion of light and air.

6. We remove the press after 24 hours and
cover the container with a breathable,
natural fabric, and place it in the dark at
65-70 ºF for a week.

7. After about one week, the
brown, syrupy liquid that
accumulates is drained off.

8. It can be stored
indefinitely in a glass
container in the
refrigerator.

9. Fermented foliar extracts can be used
as a foliar spray, diluted at about 1:500
(about one ounce to four gallons) with
water and other spray nutrients.
