Fermenting the Weeds Bugs Won't Eat

Richard Perea, Kaʻū Natural Farming (his Facebook page); farms in Ocean View, Kaʻū · USA (Hawaiʻi)

Richard Perea, a farmer from Ocean View, Kaʻū, runs an outdoor skill share on fermenting plants from his land that bugs won't eat. He shows a Christmas berry ferment of rehydrated leaves, brown sugar and water that he drinks and sprays (the 'Biome Rejuvenation Juice' of the YouTube title; it is neither Cleanser (BRV) nor Cho's Food (FPJ)), plus a hydrosol and a vodka bark extract. Then he builds a 'wild grass fertilizer' from guinea grass, forest mulch, Protectors (LAB) and water, used at a cup and a half per 55 gallons.

What they found

The question

How can a farmer turn plants that bugs won't eat, like Christmas berry and guinea grass, into ferments for soil, sprays and personal use?

How they tested it

Demonstration at a table under a tent; jars and bottles shown, including one labelled 'Wild Grass'. Only the wild grass fertilizer is built on the spot (a 5-gallon bucket stands in for a 55-gallon drum). 1) Christmas berry ferment (his 'mother of the Christmas berry'; the YouTube title calls it 'Biome Rejuvenation Juice'). Rehydrated dried Christmas berry leaves, brown sugar, and water to cover. Amounts and ratio: not stated. Step one: leave it open in the forest under a tree canopy, so it picks up forest lactic acid bacteria, kept out of the rain. Stir with a stainless steel paddle every couple of days. After day 15, seal it and fit fermenting vents (airlocks), then leave it another 15 days anaerobic. It is ready when it tastes cidery with a sharp alcohol bite. The batch shown was about a year old and is kept on the counter without refrigeration. To speed a batch up, especially in winter, add about a cup of LAB. A 25-gallon drum swelled and had to be vented. Personal use: half a cup morning and evening; a 2-day 'maintenance' course once a month (six weeks daily at first). Spray: one teaspoon per gallon of water as a foliar spray to keep bugs off. 2) Christmas berry hydrosol. Fill a pressure cooker two-thirds with Christmas berry leaves, cover with water, set a copper-coil distiller on top and boil; keep whatever comes out. He drinks a couple of tablespoons for a headache. 3) Christmas berry bark-and-root extract. Run bark and roots through a mulcher, put the chips in a 5-gallon bucket, cover with vodka and leave one month. For any of these he says 'use one eighth of a teaspoon per gallon of water' (it is not clear whether that rate is for the alcohol extract only). 4) Wild grass fertilizer (he also calls it liquid IMO; no sugar). Chop guinea grass, root ball and all, with a machete or mulcher. Fill a 55-gallon plastic drum two-thirds with it. Add about a pint of LAB and about half a 5-gallon bucket of forest mulch with white hyphae (in the bucket demo, a handful). Cover with water ('about 35 to 40 ounces' as heard, which can't fill a drum; see uncertain), stir, leave air space, cover with shade cloth or netting. It bubbles the next day; usable in 24 hours, and he leaves his 10 days. Before using a stored bottle he adds a little LAB (about half a cup in a 100-gallon mix). Use: a cup and a half to 55 gallons of water (about 1:590) as a soil drench or spray. 5) LAB. Soak brown rice outdoors, strain, and set the soak water out in the forest to catch LAB. Then milk; he uses powdered milk ($2.20 a gallon against $5.99 for fresh). Ratios and days: not stated. Use: one teaspoon per gallon of water (about 1:770). His LAB is three years old.

What was compared
  • Christmas berry ferment, foliar — 1 teaspoon per gallon of water, sprayed on everything to keep insects off
  • Christmas berry alcohol extract — 1/8 teaspoon per gallon of water (about 1:6,000); 'pretty strong'
  • Wild grass fertilizer, drench or spray — 1.5 cups per 55 gallons of water (about 1:590)
  • Guinea grass fertilizer on guinea grass areas — Sprayed or drenched around trees where guinea grass grew; rate not stated
  • Ground Christmas berry mulch plus liquid IMO — Dead trees ground with a 12-inch grinder, spread and sprayed with liquid IMO; rate not stated
  • LAB in sprays — 1 teaspoon per gallon of water; not full strength on seedlings
Results
  1. Guinea grass stopped at the line where he sprayed guinea grass fertilizer

    On one border of his land the grass stopped 'just like somebody drew a line'. He says grass drenches made the grass come back less strong. No measurement.

    ▶ 19:53 As spoken

  2. Fig trees on ground-up Christmas berry mulch were three times the size of the rest

    Dead Christmas berry trees after a fire were ground with a 12-inch grinder, spread, and sprayed with liquid IMO. Audio leaves 'fig' vs 'big' unclear.

    ▶ 19:26 As spoken

  3. Eight inches of soil on top of lava rock under heavy mulch

    A foot of mulch soaked with liquid IMO and wild grass fertilizer on his other acre in Ocean View. Time span not stated.

    ▶ 25:48 As spoken

  4. Better results from wild grass fertilizer than from IMO made with wheat mill run or IMO-4

    His comparison; no numbers. Reasons: wheat isn't grown on the island, and grass is free.

    ▶ 24:44 As spoken

  5. Japanese rose beetles stripped a Christmas berry once and never came back to it

    The tree recovered within days, he says.

    ▶ 12:02 As spoken

  6. Plain Christmas berry FPJ gave about a teaspoon of liquid

    The leaves held too little juice for the sugar method, so he switched to covering them with water (a Thai method he saw online, without the LAB).

    ▶ 9:51 As spoken

  7. IMO collected in a trash can with a guinea grass clump bloomed in 3–4 days

    A hānai daughter's method he copied with fern roots and ʻōhiʻa forest mulch; 'cotton candy' on day 3.

    ▶ 31:35 As spoken

  8. Five gallons of LAB in a 4,000-gallon catfish pond made the fish jump out and die

    His warning against overdosing.

Hold it loosely
  • Everything is one farmer's experience on his own land, from memory. No controls, no measurements.
  • The health stories (a cut hand that didn't bleed, arthritis pain gone, a friend off his cane, the cancer and diabetes claims from rain-tree.com) are personal accounts. The recording gives no evidence for them. An audience member warned that strong herbs can be hard on the kidneys.
  • Amounts for the Christmas berry ferment (leaves, sugar, water) are never given.
  • The water amount for the grass drum was heard as '35 to 40 ounces' in both transcripts, which can't cover two-thirds of a 55-gallon drum. The real figure is unclear.
  • The video is cut from four phone clips. About a minute is missing near 14:30–15:30, and the start comes in mid-sentence.
For your farm
  • Look around your land for the plants bugs leave alone. They are candidates for ferments that help keep pests off.
  • Guinea grass, root ball and all, with a handful of forest mulch, a little LAB and water, makes a cheap liquid for soil. He uses 1.5 cups per 55 gallons.
  • Go light. He sprays his ferments at about a teaspoon per gallon and warns that overdoing LAB or OHN can hurt plants and fish.
  • If a plant gives little juice with sugar, Cho's FPJ won't work well with it. Richard covered his leaves with water instead. That makes a different ferment, not FPJ.
  • Cover open ferments with mesh to keep flies out.

Next to Master Cho's teaching

  • Agrees

    Picking the tender tips before the sun hits the tree Richard pinched the top three inches of tender shoots before sunrise, as he says Cho taught. Cho says to collect just before sunrise and snap the growing points.

  • Differs

    Christmas berry ferment: rehydrated leaves, sugar, water, 15 days open then 15 days sealed Cho's FPJ is fresh, unwashed growing tips mixed 1:1 by weight with brown sugar, no water, covered with paper and done in 5–7 days. Richard's ferment uses dried leaves and water, then goes airtight with airlocks until it tastes of alcohol. It is his own ferment, so we call it by his name and not Food (FPJ). It is not Cleanser (BRV) either.

    Cho, Cho Han-Kyu's Natural Farming (Theory), p. 72–73

  • Agrees

    Leave one-third of the container for air Cho's FPJ notes say to fill two-thirds with materials and leave one-third for water, air and heat. Richard's 'one third material, one third brown sugar' is close, but Cho's two-thirds is the sugar and material already mixed.

    Fermented-Plant-JuiceFPJ, p. 1–7

  • Differs

    Wild grass fertilizer: grass, forest mulch, LAB, water, no sugar, ready in 24 hours Cho's Green Grass Liquid Fertilizer is chopped weeds plus 5–10% oil cake, chicken manure or fish meal, IMO-4, rice bran and water to the rim. It ferments 4–5 days in summer and 7–10 in winter. Richard swaps in forest mulch and LAB, skips the rice bran and uses it after a day. We found no Cho source for his 'start using within 24 hours'. His recipe is closer to JADAM's grass liquid fertilizer, which is a different system.

    Cho, Natural Farming Agricultural Materials (Recipe), p. 97

  • Goes further

    LAB from rice soak water and milk, used at a teaspoon per gallon Cho makes LAB from rice-washed water, then milk at 10:1, and uses it at 1:1000. Richard's teaspoon per gallon (about 1:770) is close. Catching the rice water in the forest and using powdered milk are his own changes.
