Hi tripty,
I've learned from experience that a tree can be protected down to about 0 degrees with only an anti-dessicant (Yates Droughtshield for example) sprayed on and a blanket over the top. Unlike humans, plants contain little or no internal heat so the blanket needs to be down to the ground kinda like a tent to trap the grounds heat(the ground is the greatest natural heat source during winter). I also find that a couple of upturned bottles filled with water help. If you want better protection a heat source such as an incandescent light bulb etc. can be added under the cover.

Good Luck

I saved this ages ago. Hope it is of interest.
Biodynamic frost protection

Trials of a Biodynamic frost protection spray look to have brought another weapon to the eternal battle between growers and the climate.

The trials were funded by the Organic Pipfruit Growers Association after the spray saved an organic apple grower's crop, while others around the Hawkes Bay (NZ) were losing millions to a bout of frosts.

The trials of ThermoMax were carried out at NZCEL(Climate Lab) in Palmerston North by Steven Mcartney and Geordie Milne from Hort Research in Hawkes Bay.

ThermoMax was sprayed on flowering

Also this short article.


'Experiments with Seasol have shown that seven days after applying Seasol the product lowers the temperature at which cells will freeze and reduces the movement of water into intercellular spaces.

It is the combination of the naturally occurring plant hormones and the alginates contained inSeasol that assists the plant's greater frost tolerance.

The 'anti-freeze' effect prevents crop damage and hastens the return to productive growth once the temperature rises.

Seasol is taken up by the plant systemically. the resistance effect lasts for several weeks after an application'.

If it's dandelion, valerian and nettle, a home gardener should be able to make the spray. You only must know how much of each.

Looks like I will have to experiment with making my own ringelstrumpf, I rang the Oz distributer today (E.E. Muir and Sons)and wes quoted about $380 for ONE LITRE. I,d like to know how they can justify that. There's a book about the quick return method of compost making that uses valerian, nettles, honey and something else (will have to look it up again) which is based on Biodynamic ideas.Tomatoes should be quick growing frost sensitive subjects to test sprays on, unless someone has a better idea.

At that price it must be just the essential oils from the plants, Jantina.

I'll just quote without comment one of Biodynamic's central themes "place cow manure in the horn of a cow and allow it to transform itself over the months" . The ensuing substance is then diluted and spread over the garden . Incantations to the Spirit optional.

IF its Bio-dynamic stuff what is the Dilution rate Jantina ?

A lot of biodynmics is just homiopathy for plants for that 1 litre may make 10,000L of spray. I am likely siting with Kert in the dilution is not the answer side of the fence. All the spirit power in the world doesn't make plants grow, nutrients do. While I can appreciate that Bio-organic is not a bad system I haven't been convinced its not a con for conscientious and good but gullible gardeners/farmers.

What is its used by date etc. ITs expensive trial at that price but it may be very concentrated.

I am thinking its more to do with mineral salts on the leaves that limits the frost effects somehow and a little bit of a boost to plant health to aid recovery, rather than any miracle.

Anyone tried spraying dilute salt water solution on the leaves as a cheap trial ?

The bloke told me that 1 litre would do 1 hectare CCS.Been very busy today getting rocks for a wall I'm building. Will get the book tonight and post the ingredients they use and people can do their own experiments. I don't understand why it's so expensive because the Biodynamic people sell their preparations very cheaply, about 10 years ago when I made enquiries it was 20 cents for enough Prep. 500 to treat an acre.

The ingredients for the compost activator are chamomile, dandelion, valerian,yarrow,stinging nettle,oak bark and pure honey.
The honey is mixed with sugar of milk at the rate of one drop of honey to one dram of sugar of milk (anyone know how much a dram is?)
The other ingredients are dried at a low temp (separately) and when dried crushed to a powder. Then take a teaspoon of each ingredient and mix thoroughly.
To use, mix as much powder as covers a five cent piece and mix with one pint of water.
Let stand for 24 hours before use. Keeps for 3 weeks.

I'm going to do some experiments and vary the combinations.
Have to admit that as I write this I'm having a giggle because I can hear you snorting in derision from here kert.
Will try the salt water test to CCS.
Will also add Seasol to some mixes.

Thanks Jantina, obviously dont try the salt trial on anything precious and dont make your soil to salty in the process :)

Jantina, are you sure comfrey isnt mentioned in there as well? The roots go down to 30ft so there are a lot of useful nutrients present in the leaves.
For kert, its also known as boneset or boneknit!

No not in the compost recipe. Would you like me to send you a copy of the book? (I know the answer will be yes!}. It's an extremely interesting book to read. By May Bruce and called the Quick Return Compost method. If you google it you will see that they still sell the activator in England.

This is interesting Jantina/CCS! "Salts" increase the boiling point of water - so do they increase the freezing point too then? (can't remember now..will google) Maybe there are more useful minerals that could be used rather than NaCl..?

Just thinking aloud - have no idea really! :)

Ok - back from google - yes salts do lower the freezing point of water.

Nick mentioned dessicants - and Agar Agar is a dessicant...
It would be an interesting experiment to try Jantina.....even if it washes off - it's good for the soil.

Ut certainly is interesting amanda, I'm going to do some experiments with tomato plants this winter. I think Nick means anti-dessicants, so is agar agar a dessicant or an antidessicant?

Gee - I don't know Jantina!? It can be used as a wetting agent for soil - so it must attract water? We need an industrial chemist I think! :)))

From what I could gather - anti dessicants are also called anti transpirants (they block up the stomata to prevent dehydration (via heat or frost) and thus moisture loss) they don't seem to provide an actual physical barrier to frost?
Agar would certainly block up the pores I reckon!
Droughtshield seems to be made of a biodegradable polymer..they don't say what it is tho'....

I'm looking for the name of a plant dessicant which is a reed - ringed reed? horsetail reed?- to grind (how?) and spray on plants impacted by funghus. Any help would be appreciated. Thanks, and best for the season.

It's horsetail , Equisetium arvense.
Boil 20 gm of horsetail leaves in 1 litre of water for 30 mins. Strain and spray. Use at the rate of 1 litre over 10m x 10m.I don't know that it is used as a cure, more as a preventative. I've heard of chamomile being used in the same way.

Horsetail is full of silica which repairs tissue both in plants & animals. For humans horsetail silica is used to repair haemeroids, urinary track & bladder infections + much much more. Unfortunately it is also a hell of a weed that is hard to get rid of due to its inbuilt silica resilience to herbicides
including glyphosate.

Unfortunately, I never saw a horsetail plant to harvest. I would love to have a plant, you can still grow them in a big pot to prevent it going weedy.
