Protective paste for logs

At the gates of winter, nature slows down its rhythms and, at least in appearance, gives us time for a little rest. In reality, even winter, rain and snow permitting, has its important works. One of these is the preparation of so-called winter treatments, which are aimed at disinfecting and nourishing 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 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 when the leaves fall, but simply nestle in the cracks of the bark, in the cavities of the branches caused by caries and desiccation and, in the most serious cases, infect portions of the root system.

For all these reasons, the use of winter treatments is extremely important, especially for those trees that during the season 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 pastes, which can be used as an alternative to Bordeaux mixture.


Protective paste based on sulfur and sodium silicate

The protective paste for logs is a preparation that is rather dense, to be applied with an old brush on all branches, the trunk and the collar.

The recipe for 10 liters of pasta is:

1 kg of fresh manure (nutritional action)

300gr of sodium silicate (protective and stimulating action)

300gr lithotamn (phytostimulating, antiparasitic, nourishing action)

200gr of bentonite (adjuvant and adhesive action)

100gr of wettable sulfur (fungicidal action)

N.B .: add or decrease the water / bentonite ratio to obtain a good density suitable for brushing.


Potassium sulphate and rock dust based log paste

500g of potassium sulphate (nourishing and antiparasitic action)

300gr of rock dust (protective action)

600gr of sodium silicate (protective and stimulating action)

200gr of bentonite (adjuvant and adhesive action)

500gr of potassium soap with sulfur (adhesive, detergent on honeydew, pesticide)


Protective spraying paste

N.B .: it is important to spray the trunks and buds well to obtain a better antibiotic and fungicidal effect.

300gr of potassium sulphate (nourishing and antiparasitic action)

150gr of rock dust (protective action)

150gr of sodium silicate (protective and stimulating action)

100gr of sulfur (fungicidal action)

Once you have become more familiar with the preparation of pasta, it is possible to insert variations according to need in the defense of particular diseases and in the availability of ingredients.

However, it should be emphasized that there are some ingredients that are incompatible, for example rock dust is miscible with sulfur, but not with copper.


When to apply the pastes

These preparations must be applied when the trunks are rather dry and possibly on days without rainfall: this favors a greater persistence of the product.

Such preparations are quite dense so the trunk will appear as painted and this protective layer will slowly be absorbed or dissolve over the winter.

Furthermore, the surplus that drips to the ground enriches the soil anyway.

At the vegetative restart, if you have applied your paste well, you will have a healthier and stronger plant, ready to better face the adversities of the season. Mainly treat fruit trees, in particular peach, cherry and apricot trees and in general all trees with branch cancers and infections of the lignified organs.

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 man. Using a biological / preventive defense strategy also reduces damage to beneficial insects, first of all bees, which are very intolerant to sprayed treatments during flowering periods (in particular those based on copper and systemic insecticides), while not it causes no problem 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 place but not too cold and safe from children and inexperienced.
