Protective paste for logs

At the gates of winter nature slows down its rhythms and, at least in appearance, leaves us time for some rest. In reality, even winter, rain and snow permitting, has its important works. One of these is the preparation of the so-called winter treatments, which are intended to disinfect and nourish the lignified organs of our trees.
Too often we tend to associate the use of a pesticide or an entomorepellent preparation (nettle macerate) with the presence of the leaves on the tree and its full vegetative activity. In reality, the care and protection of the trunk, branches and root system is equally important and effective.
This is because the organisms responsible for the most common plant diseases do not disappear with the fall of the leaves, but simply nest among the fissures of the cortex, in the hollows of the ramifications caused by caries and desiccations and, in the most serious cases, infect portions of the root system.
For all these reasons, the use of winter treatments is of extreme importance, especially for those trees that during the season have presented symptoms and problems related to some pathogen.
Among all, the most famous preparation is undoubtedly the Bordeaux mixture, a paste that can be more or less dense based on hydrated lime and copper sulphate which has a strong and persistent fungicidal action. Excellent for use in agriculture, it is also suitable for our garden.
Let's now discover some protective paste, which can be used as an alternative to the Bordeaux mixture.

Protective paste based on sulfur and sodium silicate

The protective paste for trunks is a preparation that is rather dense, to be applied with an old brush on all the branches, the trunk and the collar.
The recipe for 10 liters of pasta is:
1kg of fresh manure (nutritional action)
300gr of sodium silicate (protective and stimulating action)
300gr lithotamnio (phytostimulant, antiparasitic, nourishing action)
200g of bentonite (adjuvant and adhesive action)
100gr of wettable sulfur (fungicidal action)
NB: add or reduce the water / bentonite ratio to obtain a good density suitable for brushing.

Log paste based on potassium sulphate and rock dust

500g of potassium sulphate (nutritive and anti-parasitic action)
300gr of rock dust (protective action)
600g of sodium silicate (protective and stimulating action)
200g of bentonite (adjuvant and adhesive action)
500g of potassium sulfur soap (adhesive, honeydew detergent, pesticide)

Spraying protective paste

N.B .: it is important to spray well trunks and buds to get a better antibiotic and fungicide effect.
300gr of potassium sulphate (nutritive and anti-parasitic action)
150gr of rock dust (protective action)
150g of sodium silicate (protective and stimulating action)
100g of sulfur (fungicidal action)
Once you have become more familiar with the preparation of the pastas, it is possible to insert variations depending on your needs in the defense of particular diseases and in the availability of the ingredients.
However, it should be emphasized that there are some ingredients that are incompatible, for example rock dust can be mixed with sulfur, but not copper.

When to apply the pastes

These preparations must be applied when the trunks are rather dry and possibly in days without rainfall: this favors a greater persistence of the product.
These preparations are rather dense so the trunk will appear to be painted and this protective layer will be slowly absorbed or dissolved during the winter.
Moreover, the surplus that leaks to the ground enriches the soil anyway.
At the vegetative restart, if you have applied your pasta well, you will have a healthier and stronger plant, ready to better face the season's adversities. Above all, treat fruit trees, in particular peach, cherry and apricot trees, and in general all trees with rameal cancers and lignified organ infections.
The product can also be used for woody shrubs.
These are preparations allowed in organic farming and therefore less harmful to other living organisms, including humans. Using a biological / preventive defense strategy also reduces damage to useful insects, first of all bees, which are very intolerant to treatments sprayed during periods of flowering (in particular those based on copper and systemic insecticides), while not any problem is caused by treating in the winter period.
Learning the characteristics of the individual ingredients and mixing them together is a good habit for those who want to become an expert gardener, setting up a small home workshop with a few buckets and old wooden spoons is simple; remember to always keep the products in a cool but not too cold and safe place for children and inexperienced.
