Let's talk about foliars: what's in your arsenal, what works for you, and helping others find what works for them. I've put this thread here in organics because most foliar sprayers I meet on ic are organic users, but I'd like to keep the discussion open to synthetic fertilizers that are used in organic gardening such as potassium silicate(many of you use this as pro-tekt or Ag-Sil). Let's keep things friendly and keep our dogma and ideology to a minimum. Which is to say no immediate jihads against bottled products, and an open mind to the place of synthetics in organic gardening. There are many ways to skin a cat.

I'd urge all of you who haven't to read Donald Hopkins "Chemicals, Humus, and the Soil" which examines without ideological blindness the interaction between chemical fertilizers and the soil. His views were a level-headed refutation of much of Albert Howard and Rodale's extremism as well as a refutation of the growing use of chemical fertilizers. It's a shame he's been mostly forgotten as people take hardline sides in the Organic v. Synthetic war. For the record I'm almost entirely organic, but I've been known to make use of ingredients like Potassium Silicate, and rarely, synthetic urea to speed up extremely high-carbon compost heaps.

All caveats, disclaimers and intros out of the way, let's get to business. I'd like to start off with the recipe for the old Brix Mix, which used to be a standard for many of us in the Big Plants thread, and which Happy Valley shared once they realized their product was too "alive" to ship. This is posted multiple places here on ic, and came directly from Happy Valley:

"The following are the proportions of ingredients we used in our Brix Mixes. Feel free to change the blend to suit your needs and the availability of the ingredients. You do not have to use every ingredient for the mix to be beneficial. For example: if you don’t have Phytamin 4-3-4, you could sub a liquid fish or a dry fish powder, like HFPC hydrolyzed fish. If you prefer, you can use a liquid kelp extract in place of maxicrop. If you don’t have a trace mineral deficiency, you can do without the MB powdered chelates. Keep in mind that kelps, such as maxicrop, do provide some trace minerals. If you don’t have access to a liquid sulfur, just leave it out of the blend.

Liquid Brix Mix:
16.5% Molasses
16.5% non GMO pure Malt
25% Phytamin 4-3-4
24% Humax
16.5% liquid sulfur
1.5% Therm-X 70

Dry Brix Mix:
13% Maxicrop
19% Fertall MB Powdered Chelates
31% Powdered sugar
37% Diamond K soluble Sulfate of Potash"
For every gallon of spray you would add 2-5T dry,mix well and add 1-3T liquid.


Sprouted Barley Tea
Here's the recipe for the sprouted barley tea that many of us use to good effect. Many thanks to John Deere for his summation and for others in the community who have experimented, improved, and shared their results:

"*Weigh out 2 oz. of Barley seed and remove any foreign matter by the seeds into a large jar and fill it half-way with water and agitate to wash the barley. Pour off loose husks & dirt that float to the top. Drain in a colander. Repeat until everything has been removed.
*Soak the seeds in water for 8 - 10 hours. Drain the seeds and weigh after completely draining the water off. Assuming you started with 56 grams, you want to hit a minimum of 84 grams at the end of these processes.
*Let the Barley rest for 8 - 10 hours and then soak for another 8 hours, drain and weigh. Repeat if necessary but that's not too unlikely.
*Take a piece of cloth and you want to use something as 'raw' as possible like hemp cloth, organic cotton, linen, canvas, flax, etc. - just check with a large fabric store. If you buy a piece that is a square it probably helps or doesn't.
*Wet your cloth, wring out and fold it 2 times. During the rest cycles this is where you want to let the seeds rest. You want moisture surrounding the seeds but not water.
*Once you hit 84+ grams, spread your seeds again in the middle of this folded piece of fabric, place that in a brown paper bag - 55F - 65F ambient temperatures will move this along quickly.
*When the shoots inside the seed have grown the length of the seed you're done. You're not growing sprouts but rather activating the enzymes and the compounds in the endosperm as described in the post above.
*Take these seeds and put them in a blender and some water and get it to a puree to the extent possible. Using 56 grams to start will give enough puree to make 5 gallons of tea.
*Water your plants with this diluted tea. This will give you far, far more enzymes than the straight sprouting method. One thing about beer brewers is that they live & die by enzyme levels extracted from seeds and this article is cited on several home brew forums."

The next big foliar that seems up for discussion is foliar calcium. Many here us CA-25 in its various forms, however growers such as milkyjoe and backyardgardener have been having great success with Albion Ca, either with or without boron added. Both of these products are expensive for their weight, however the dosage required is so small that a 4lbs jar of CA-25 at $125 should last you multiple years.

I'll be editing this post for improvement as things continue. One Love and Big Ups!

I've experimented with changing things out here and there on the brix mix. I found the powdered sugar redundant with the molasses and malt, and I've added in the sprouted barley tea so many of us enjoy. Fert-All's MB Powdered Chelates is nigh unfindable, and in my case I've replaced both Humax and Fertall with BioAG's TM-7 to provide quality humic acid and trace minerals. Just be forewarned that BioAG's products are strong, and I tend to err on the light side when adding their products to sprays.

For those on the east coast Neptune's Harvest is the easiest to find fish fertilizer but I've discovered the 2-4-2 is just too much phosphorus for a general spray, and have seen some lockout and burn from it. The higher N, lower P phytamin seems preferable.

I'm currently on the fence about Sulfate of Potash. There's some argument about the place of K in a foliar spray, but with the lack of acid rain these days gardeners are finding they need more sulphur than they did when it was coming out of the sky, and Potassium Sulfate seems a logical source and should also keep down fungal issues.

Fantastic information Luther. I love the thread, and will be tagged from here on out.

Last year I had a grow in the Ganjarebel sub-forum and I took brix readings all season. For me, what made my brix levels spike were compost teas. I used Microbeman's recipe for the most part, http://www.microbeorganics.com/, and it always raised my brix by several numbers for several days.

What is your experience with foliar applications of compost teas in relation to brix readings?

Last years thread for reference....https://www.icmag.com/ic/showthread.php?t=262017

MicrobeMan's recipe:
[vermi]compost – 2.38%

unsulphured pure black strap molasses - 0.50% [but you can use a maximum 0.75%]

fish hydrolysate (high quality) - 0.063%
Do not use chemically deodorized liquid fish!

kelp meal - 0.25% max. [Less is more!]
NOTE: This is a maximum amount of kelp and you can experiment using less. This is using regular grade kelp meal for livestock. If you have soluble kelp, I recommend using smaller amounts. As noted earlier kelp meal can initially delay bacterial multiplication and fungal growth in ACT.

soft rock phosphate granules/powder - 0.063% Consider this optional. In the past 2 years I’ve become more aware of the possibility of polonium 210 and lead content in soft rock phosphate which is radioactive. This varies depending on how it was mined and where. If you wish to use this in ACT check all available data. Look for heavy metal testing
We grind up the granules into a powder with a coffee grinder

The brew time should average around 36 hours and no longer than 48 hours. If you have a microscope then stop when the microbes desired are observed. Otherwise smell for the foodstocks being used up, possible rank odor (indicating anaerobes) and a positive earthy or mushroom-like aroma.

I used to be very big on ACT but in the past year phased it out entirely because of life/time constraints. I always saw more of a boost from EWC drench when things were doing poorly than I did from ACT foliar/drenching.

Nice thread thus far. "EWC drench"? Is that just EWC mixed with water only and then dumped on the plant?

tagged thanks for the info luther. I've also cut out most of my ACT but still do live ewc foliar 2 to 3 times weekly, @ night. I don't even bubble, just let soak for an hour.

What do you then pH your foliar too? Or in your opinion do you think that isn't necessary?

i still use ACT's for foliar sprays, it seems to help a great deal with fungus and mold issues, neither of which do i have and that includes my orchard. ewc drenches are okay for any deficiencies but will not aid in canopy pest problems.

i use 6-tbs molassis, about 2tbs kelp, 2 tbs alfalfa and about a 1/2 cup of my organic soil to 5 gallons of water, bubble it in the vortex for about 18-20 hours. i usually use it straight on my indoor plants and mix it up to 3-1 for outdoor garden and orchard use.

Yes. There are times, usually mid-flowering with larger plants when the soil isn't dialed in when nothing I do seems to fix the problem. Making a slurry of earthworm castings and water always seems to perk things up. Your miles may vary of course, depending on quality of castings and severity of issues.

I've never pH'd my foliars. Perhaps it's necessary and I've never known any better, but I'm currently of the opinion it's not necessary. I'm not against pH testing, but I believe it to be a very misunderstood beast. People think of it as a thing, but it's no more a thing than barometric pressure. It's just a representation of hydrogen exchange, which can give you an inkling of what is off, but can never tell you exactly what is off.

I've done a variety of things with more leaves burnt then.... well.. no, I will admit it LOL...

I've been taking a minimalistic approach to foliars of late... this round has never even seen neem... and I've now got a few spider mites to show for it, and my rove beetles just dont get that high in the plant without getting fly-trapped so I must order more predatory insects...

I use 1 gallon glass jugs, and a 30-60 gallon pump with 2x30 gal air outputs... I aerate everything.... these peppermint leaves were cut off my peppermint 3 weeks ago and have been bubbling ever since...

2014_07_16_2_1a5c44b6b3ff3fc4a0cf_1.jpg


I've done alfalfa in the same manner for triacontanol although my leaves were scorched even after rinsing... perhaps i use too strong a concentration....

I'm a personal fan of aloe & coconut water foliars although I know there is a school of thought that coconut water is wasteful in a foliar, however it is not a thought to which I subscribe... the enzymes in coconut water are similar to a sprouted seed tea. of which I use barley, but not the purple kind from tibet LOL, I use the stuff from "el mercado" (my local mexican market)

I do not measure things, and I do not even own a scrap of litmus paper to check ph if I wanted to...

I agree that it's misunderstood. Then do you agree that micro/macro elements are exchanged within a plant better or more readily at different pH levels?

I've done plenty of soil-less growing and know that pH is paramount when it comes to uptake of nutrients (macro or micro). If you don't believe that, try feeding a plant in water or coco with pH'd water in the mid 6's. You will FAIL every time! Even "quality" soil seller's monitor the pH of the soil in there mixes. I think ph'ing is an under rated "barometer". Not trying to argue, just making a point.

Foliar sprays for pest control:

Week 1,3,5 et al. until early flower:
Finely chop 1 onion and 2 medium cloves of garlic. Put ingredients into a blender with 2 cups of water and blend on high. Strain out pulp. Pour liquid into spray bottle. Spray a fine mist on plants, making sure to coat both tops and bottoms of leaves.

Week 2,4,6 et al. until early flower:
Mix of 1 gram AgSil 16H with 1 ounce Neem Oil to emulsify the oil. Then mix this emulsified oil with one gallon final volume clean water. Spray every other week covering all plant surfaces (top and bottom of leaves NOT BUDS) until it runs off.


When you spray the plants, and make sure you get the undersides of the leaves(that's where they lay eggs). Do not spray buds unless very early flower. You'll want to do this when the lights are about to go off (or else the leaves will get burned).

Id guess thats from coot... I got many pages of random quotes saved on my desktop

Pesticide Sprays

Quote: So while you're at Whole Foods pick-up Cilantro (organic ONLY) and when you get home toss the entire bunch (sans the tie around the middle) into a food processor with enough water to make a slurry or puree.

Add this to 1 gallon of clear water and let it sit for 36 - 48 hours. No more than this.

Add 1 cup of strained Cilantro tea to 15 cups of water = 1 gallon. Allow for 1/4 cup of Aloe vera juice and use 1 tsp. of Pro-TeKt.

Wait until the it's almost "light's out" and spray the top of the soil, every branch, every leaf from top to bottom. You want the plant to look like you haven't watered in several days and it's drooping big time.

Leave the ventilation system going and by morning you won't have anything hopping, flying, whatever in your chamber. Follow this up every 4 days until you're completed 4 applications.

Done. Finis. Ovah.

This is not a pesticide in the usual definition and without a long explanation you might need to trust me on this one - I apply this and other 'Mint' teas to hydrate the soil every couple of weeks.

"Bio Stimulants"

If you're concerned then pick-up a couple of throw-away plants at Home Depot - Marigolds are a good one. Water this plant with your Cilantro mix and see for yourself.

Preventative Spray...1-2x per week

Quote: 4 tsp. of organic neem oil
2 tsp. of Pro-TeKt

I mix this in a shot glass until it's completely emulsified.

I add this to 1 gallon of tepid water - you want around 70F and stir or shake this until it's completely dispersed and then I add 1/4 cup of aloe vera extract and shake again as much as possible to activate the foaming action of the aloe vera extract's Saponins.

I spray the plant until the leaves hang like they need to be watered. Top and bottom of the leaves, all the branches and the top of the soil.

Coot- Yarrow Tea
Cut flowers and remove as much of the stem as possible. Take 4 cups of loose flowers and add that to 1gal of water. Let stand for 2 days and strain. Mix 2 cups yarrow tea w/ 14 cups water = 1gal. Super safe drench or foliar. Do not let ferment.

Coot- Quick Natural Tea
Take a couple of cups of chopped/diced/ pureed whatever of dandelions, stinging nettles, comfrey- and add to 5 gals of water. Let sit no longer than 3 days. Drench and foliar. Add aloe and protekt. Stinging nettles used this way is a powerful pesticide and fungicide. If looking for N, allow nettles to ferment 3-4 weeks.

Barley tea- Coot
Take 1/4 cup barley seed (not pearled) sprout like you would alfalfa,mung bean etc. Drain and rinse after 24 hrs. Once sprouted add to 1 gal water and let sit 3-4 days. Strain and mix 2 cups 'tea' to 14 cups water = 1 gal. Foliar or water into soil. Works well w/ alfalfa,wheat,oat etc. Think "enzymes".

Neo420 - Willow Tea
1. Collect handfull of willow branch twigs, preferably the tips of branches where the highest levels of IBA and SA are found. No dead branches.
2.Remove all leaves, and cut twigs short. Boil a gallon of water.
3. Put twigs into 1 gal jar, pour in water, seal jar. You now have willow tea. Use undiluted.

Coot- Spanish Thyme- Mint family recipe
Take 1 cup of leaves. Make a puree in a blender. Add enough water to make 1 gallon. Let sit 48 hrs in a warm place. After 48hrs, strain and you now have pesticide concentrate. 1 cup concentrate to 15 cups water. Add protekt and aloe.

Comfrey Pesticide and Fungicide- Coot
Take fresh comfrey leaves, puree or grind to a pulp and add 1 quart of this to 5 gals of water, let sit a couple of hours, strain and dilute w/ 2x water so you now have 15 gallons.

Coot- Pure Neem Oil
Coot uses 1tbs per gal water. Emulsify w/ 1tsp Protekt and add to tepid water. Use 1/4 cup aloe vera as a surfactant."

Rat control
Mix 1 cup cayenne pepper w/ 1 cup DE and add enough water to make a paste. Take latex gloves and cake the stem w/ it.

The basic method of fermentation is simple enough, which is not to say anything goes. First you need a container made of a nonreactive material. A 50-gallon plastic garbage can works fine. You need to cover your container during fermentation, but not tightly, or it might explode! Either punch some holes in your garbage can lid or cover the can with a piece of burlap or other cloth. While you can use smaller containers, 50 gallons is an optimal homeowner-scale size that is big enough to help moderate temperature extremes during fermentation.An unheated garage or outbuilding is a good place to conduct the fermentation, the speed of which is temperature dependent. The higher the temperature--up to a point--the faster the fermentation.

The water you use is very important. The ideal source of water is rain, being free of calcareous minerals or additives such as chlorine which can retard or stop fermentation. If you must use hard well water, add a bit of vinegar to it to lower the pH. City water should be allowed to stand several days to allow the chlorine to evaporate before you use it for your extracts.

The duration of fermentation can range from a few days to a couple of weeks. When the mixture stops bubbling when you stir or otherwise move the contents, fermentation is complete. Check your brew daily.

It is imperative that you filter your extract. Doing so stops the fermentation from going too far, and also prevents globs of stuff from plugging up your sprayer or watering can when you apply the brew. Use a very fine strainer lined with cheesecloth, an old clean teeshirt, anything short of a coffee filter or other filter paper, which filters out too much.

Store your extract in stainless steel or plastic containers in a cool place, around 40-50 degrees F being ideal. French folks like to use 5-gallon plastic wine containers, appropriately enough. While a wine cellar is also an excellent place to store your extracts, make sure to label carefully!

Once you have your made your extract or infusion, you of course need to apply it. Most often, you spray it on, just as you would a conventional pesticide or foliar fertilizer, taking care to cover the undersides of leaves. But some remedies are applied as a soil drench. This is best accomplished with a good old-fashioned watering can.

Okay, now that you know the basics, here is the roster of beneficial plants and how to use them.



Wormwood (Artemisia absinthium) Perennial plant with silvery, aromatic foliage.
Action. Repellent, especially against cabbage butterflies and codling moth on apples during period of egg-laying. Fungicidal against rust on currants.
Fermented extract (2 lbs. of fresh plant material to 2.5 gallons water) Undiluted for rust on currants. Undiluted sprayed on soil to repel slugs. Diluted to 10% against codling moth and cabbage worm. Note: Do not throw detritus of fermentation on compost, as it will slow its breakdown.

Fernleaf yarrow (Achillea millefolium)
Perennial plant with ferny, silvery, aromatic foliage and white flowers.
Active ingredients: pro-azulene, a volatile oil; isovalerianic and salicylic acids (salicylic acid is aspirin, which is why a tea of this plant reduces pain and fever in humans.)
Action. Promotes compost breakdown; potentiates fungicides.
Cold maceration. 1 oz. of dried flowers in 1 quart of water; macerate 24 hours. Add to fungicide treatment, such as horsetail or tansy.

Garlic (Allium sativum)
Needs no explanation, except to say that garlic is perennial if left in place.
Active ingredients. Sulfur-containing compounds.
Action. Insecticide and fungicide.
Preparation. In decoction: chop 4 oz. peeled cloves and add to 1 quart water. Bring to boil, cover and remove from heat, infuse for one hour. Strain and use without diluting. Used as a soil drench, excellent to prevent damping off of seedlings. In oil maceration: Place 4 oz. of peeled cloves and 2 T. linseed oil in a mixer or blender and pulverize. Filter, washing the filtrate (and mixing in) 1 qt. rainwater. Store one week before using. Adding a bit of soap as a surfactant before spraying is useful. Effective against aphids and mites.
Note: This is a great use for spare garlic at the end of the winter storage season, which is beginning to sprout and taste unpalatable.

Cocklebur (Arctium lappa). Infamous biennial weed.
Active ingredients. Tanins, mucilage, resins, sulfate and potassium phosphate, calcium, and magnesium.
Action. Fungicide effective against mildew on potatoes.
Preparation. Use the whole plant before flowering. The root has the most active ingredients. In fermented extract, use 2 lbs. fresh plant to 2.5 gal. of water. Attention: strong odor! Filter and dilute to 5% before spraying on potato foliage. Also, just pick the leaves and use them as a mulch on your potatoes.

Nasturtium (Trapaeolum majus). Flowering annual.
Active ingredients. Sulfur-containing compounds.
Action. Fungicidal against canker on tree fruits. Insectifuge against white fly (repellent).
Preparation. In infusion, 2 lbs. fresh leaves in 5 quarts of water. Boil water, add leaves, infuse like tea one hour. Use undiluted on fruit trees. Dilute to 30% to spray tomatoes against mildew.

Comfreys (Symphytum officinalis, S. x uplandicum). Flowering perennial.
Active ingredients. Allantoin, which stimulates cell multiplication. This is why allantoin is such an excellent ingredient for skin creams, especially for chapped skin.
Action.Comfrey is a powerful stimulator of all cell multiplication, e.g. growth. It stimulates microbial growth in the soil, and in compost, thus acting as an 'activator'. Comfrey stimulates seedling development as well as foliar growth.
Preparation. In fermented extract, use 2 lbs. of fresh leaves in 2.5 gal. of water. As a soil drench, dilute to 20%; as a foliar fertilizer and seedling fertilizer, dilute to 5%.

Spurge (Euphorbia lathyris). Hardy perennial.
Active ingredient. Euphorbone.
Action. Repels moles and voles, but must be prepared and sprayed to be effective. Having the plant on your property does not suffice.
Preparation. In fermented extract, harvest the stems and leaves; the terminals have the most active ingredient, from April to October. Caution! The milky sap of this plant causes skin irritations! Wear long-cuffed gloves to protect your hands and arms. Use 2 lbs. fresh plant material per 2.5 gals. of water. Spray around cultivated areas.

Bracken fern and male fern. (Pteridium aquilinum, Dryopteris felix-mas). Perennial plant.
Action. Insecticide and insectifuge.
Active ingredients. Gallic and acetic acids; tannin; cyanogenic heterosides; potassium; aldehydes transformed to methaldehydes after fermentation.
Preparation. In fermented extract, 2 lbs of fresh leaves to 2.5 gal. of water. May be fermented simultaneously with nettle or horsetail. Dilute to 10% before spraying. Effective against some pests of potato and grape, very effective against wooly aphid. Note: bracken fern is indigenous in many areas, especially in well-drained acid soils, and is often considered invasive, as it is rhizomatous.

Lavender (Lavandula angustifolia). Flowering perennial.
Active ingredients. Over 250 different compounds!
Action. Insectifuge, insecticide.
Preparation. In fermented extract, 2 lbs. of fresh plant material per 2.5 gal. of water, dilute to 10% before using. For dried material, use 7 oz.
In simple infusion, use 4 oz. of fresh plant material in 1 qt. of water, or 2/3 oz. of dried plant material per quart.
Note: If you live in a cool climate, your lavender will be less potent than that grown in a hot climate. Double the quantities or use dried plant material from a southern source.


English Ivy (Hedera helix). Perennial vine.
Active ingredient. Heteroside which is liberated during fermentation.
Action. Insectifuge and insecticide against white fly, spider mites, and aphids.
Preparation. In fermented extract, use 2 lbs. chopped leaves in 2.5 gal. of water. In observing fermentation, don't confuse the foam caused by the saponins in the leaves with the gas bubbles of fermentation. Dilute to 5% before spraying. Beekeepers in the 18th century rubbed their hands with ivy to protect themselves from bee stings. Caution! The extract is toxic and must be kept out of the reach of children. Also, many people are allergic to the sap of ivy and/or to the fine hairs on the reverse of the leaves. Wear gloves to protect yourself.

Lemon balm. (Melissa officinalis). Perennial aromatic culinary and medicinal herb.
Active ingredient. Many aromatic compounds.
Action. Insectifuge against aphids, mosquitos, white fly, and ants.
Preparation. In infusion, 2 oz. of fresh plant in 1 qt. of water. Allow to cool, filter, and spray without diluting. Note: Do not use on seedling beds as it can prevent germination of seedlings.

Peppermint. (Mentha piperita) Perennial aromatic culinary and medicinal herb.
Active ingredients. Many aromatic compounds.
Action. Insectifuge and insecticide against aphids and spider mites.
Preparation. In infusion, 4 oz. of fresh plant in 1 qt. of water. Allow to cool, filter, and spray undiluted.
In fermented extract, 2 lbs. of fresh plant to 2.5 gal. of water. Ferments extremely fast. Dilute to 10% before using. Note: Impedes germination so don't use on seedling beds.

Stinging Nettle (Urtica dioica). Perennial weed.
Active ingredients. A cocktail of ingredients still poorly analyzed but including formic acid, as well as iron, nitrogen, and many trace minerals. Acts as an immunostimulant for plants.
Action. Strongly stimulant to both microbial and plant growth, thus a compost activator as well as fertiliser. Insectifuge and sometimes insecticide against aphids, mites, and other pests.
Preparation. Use of the whole plant before flowering. Studies have shown that including the roots adds a fungicidal action to the extract. In fermented extract (the famous purin d'ortie), 2 lbs. of fresh plant in 2.5 gal. of water, fermented for a few days only. Dilute to 20% before using as soil drench or foliar feed. Use full strength as a natural herbicide (it kills with 'fertilizer burn' because it is so rich). Soak bareroot plants for 30 minutes in the pure extract or for 12 hours in a 20% dilution before planting to stimulate rapid establishment and vigor.

The nettle reigns supreme among plants for fermentation in France. The fermented extract is sold commercially in garden centers, and clubs and associations of nettle fanatics exist throughout France. Needless to say perhaps, but wear gloves when handling nettles. It's not for nothing they're called 'stinging.'

Horsetail. (Equisetum arvense). Perennial plant and medicinal herb.
Active ingredients. Diverse alkaloids, nicotinic acid, silica.
Action. Insectifuge, preventive fungicide, plant tonic and growth stimulant.
Preparation. In decoction, boil 1 lb. of fresh plant with 5 qts. of water for 1 hour, allow to infuse 12 hours, filter and dilute to 20%.
In fermented extract, 1/2 lb. of dried plant in 2.5 gal. of water. Dilute to 5% before using.
Horsetail, along with nettle and fern, form the Big Three among medicinal plants for plants, according to the French. I remember my Swiss grandmother gathering horsetail and drying it in pillowcases for use in astringent poultices.

Pyrethrum (Tanacetum cinerariifolium). Perennial.
Active ingredient. Pyrethrins.
Action. Insecticide against aphids, cabbage fly, whitefly, carrot fly, and others. Does not hurt bees.
Preparation. Harvest the flowers when open, and dry them. In infusion, use 1 oz. in 2 qts. of water. Filter when cool and spray undiluted. In fermented extract, use 3 oz. in 2.5 gal. of water. Dilute to 20%. Spray after sundown or in very early morning.

Horseradish (Armoracia rusticana)
Perennial culinary herb.
Active ingredients. Sulfuric heteroside, glucosinolate.
Action. Fungicide against blackspot on cherries.
Preparation. In infusion, 12 oz. of fresh plant material (leaves and roots chopped) in 2 1/2 gal. of water. Filter when cool and spray undiluted. In fermented extract, 4 oz. of chopped root in 2.5 gal. of water. Use full strength on seedlings for damping off.

Rhubarb (Rheum rhaponticum).
Perennial potager plant.
Active ingredients. Oxalic acid as salt of calcium.
Action. Insectifuge against aphids, caterpillars, and other larvae. Repulsive to herbivores.
Preparation. In cold maceration, use 1 lb. of chopped leaves in 3 quarts of water; allow to soak 24 hours before filtering. Use full strength. This is a great way to use rhubarb leaves as you eat the stalks.

Rue (Ruta graveolens). Perennial herb.
Active ingredients. Tannins, heterosides, malic acid, glucosides, and others.
Action. Insecticide and repulsive.
Preparation. Harvest fresh leaves and stems before flowering. In fermented extract, 2 lbs. of fresh plant material in 2.5 gal. of water fermented for 10 days. Dilute to 20%. Repels mice, chipmunks, and other chewers. Spray against aphids.

Dockweed (Rumex obtusifolius). Perennial weed.
Active ingredients. Have not been studied.
Action. Fungicide against canker on apples and pears.
Preparation. In infusion, 2 lbs. fresh leaves in 5 qts. boiling water. Filter when cool, spray full strength on cankers. Treat young trees preventatively. Spring is best time.

Soapwort (Saponaria officinalis). Flowering perennial.
Active ingredients. Saponins.
Action. Insecticide, insectifuge.
Preparation. In infusion, 4 oz. fresh material in 1 qt. boiling water. Filter when cool and spray undiluted. In fermented extract, 2 lbs. fresh plant material in 2.5 gal. of water. Dilute to 10% before using.


Sage. (Salvia officinalis). Perennial herb.
Active ingredients. Monoterpenones, including thujone, camphor, and others, aldehydes, coumarin.
Action. Insectifuge, fungicide.
Preparation. In infusion for insectifuge, 4 oz. of fresh plant material in 1 qt. boiling water. Filter when cool and use full strength. In fermented extract, 2 lbs. of fresh leaves and terminals in 2.5 gal. of water, diluted to 10%, against mildew on potatoes.

Common Elderberry (Sambucus nigra). Large shrub to small tree.
Active ingredients. Sambucine.Action. Powerful repellant; fungicide.
Preparation. In decoction, 2 lbs. of leaves soaked for 24 hours in 2.5 gal. of water, then boiled for 30 minutes. Spray undiluted against aphids, beetles, caterpillars. In fermented extract, use 2 lbs. fresh leaves in 2.5 gal. of water. Use undiluted against shelf fungus infections on trees.

Tansy (Tanacetum vulgare). Perennial plant (invasive in sandy soils).
Active ingredients. Not studied.
Action. Insectifuge, insecticide, fungicide against rust and mildew.
Preparation. In fermented extract, 2 lbs. of fresh plant material in 2.5 gal. of water. Use nondiluted against cabbage fly. In infusion, 1 oz. of flowers in 1 qt. of boiling water. Filter when cool and spray undiluted against aphids, mildew, and rust. Caution: don't throw residues on compost as tansy inhibits its breakdown.

thats about all I got, and I know some are teas and not foliars, but I didn't wanna edit...

I agree that it's misunderstood. Then do you agree that micro/macro elements are exchanged within a plant better or more readily at different pH levels?

I've done plenty of soil-less growing and know that pH is paramount when it comes to uptake of nutrients (macro or micro). If you don't believe that, try feeding a plant in water or coco with pH'd water in the mid 6's. You will FAIL every time! Even "quality" soil seller's monitor the pH of the soil in there mixes. I think ph'ing is an under rated "barometer". Not trying to argue, just making a point.

In soil-less growing you generally have absolute 0 CEC to adsorb elements... so it must take what you give, when you give it... which is a completely different relationship between root and media than a good soil would have... I haven't ever found a "quality" bagged soil... not to my standard anyway. LOL... I wont use bone, blood or guano...

Agreed, but this thread is about foliar feeding not soil feeding.. No?

I would agree that pH is a main factor in nute uptake but mid 6=failer?
My coco fluxes 6.2-6.5 and it is far from a failer, haha! There is a pretty big window of opportunity for nute uptake. Drastic swings caused by fucking with pH buffers too much will have bad effects but slight fluctuation can be a good thing as differnt macro's and micro's uptake at differn't pH levels.

I have a very poor time articulating what I think I know about pH. Yes I agree, but it's less that pH causes nutrients to exchange at different levels than the elemental makeup of a soil determines the exchange of nutrients and pH is a representation of that exchange because of what a common element hydrogen is. You may have lockout of several nutrients because your mix is oversaturated with Mg. A pH which is off represents that but it's not explaining what is causing the lockout. That's what I think people misunderstand.

Agreed, but this thread is about foliar feeding not soil feeding.. No?

I think they're interconnected. If your soil isn't dialed in and balanced according to Albrecht ratios your foliars are not going to have the power they should. Foliars should compliment a working soil, not supplement an off-balance one. You're spitting in the wind if you attempt to keep a plant up to speed with foliar if the soil is running on empty. You also seem to be talking coco and mediums other than soil, which unfortunately I very little experience with.


SeaF0ur, I completely forgot to mention IPM in my foliar intro! I'm definitely a keen fan of neem oil. I used to be more keen on soaking rosemary, oregano, cilantro, mint, and all the rest for pest sprays, but these days I'm of the opinion that we're better off using the concentrated essential oils of those herbs than attempting to get compounds like linalool from a water soak. Bone, blood, feather, guano. It all has its place in my book.
