Review and advice.

Organic therefore safe?

It is important to start with a small important clarification concerning the organic treatments fruit trees. Organic does not mean safe! Too often we tend to believe that anything ecological / biological poses no risk to humans. It's wrong. You can imagine that a product that kills insects is not particularly harmless ... quite natural as it is.

Bordeaux mixture

Very well known to all gardeners, the Bordeaux mixture is a mixture authorized in organic farming. A mixture of copper sulphate and lime, Bordeaux mixture comes in the form of a blue powder to be diluted in water.

In the second case, it is placed in the crevices of the trunk. Derived from the spores of a fungus, trichoderma is an organic treatment against pests of your fruit trees.

Marseille soap

Yes, by choosing an organic Marseille soap made from olive oil (no animal fat obviously) you can, by grating it and melting it in water, produce an entirely natural insecticide and ... nontoxic !

You can optionally add a little vegetable oil to the mixture.

The principle of operation of this "soup" is to suffocate the aphids where the mealybugs. Care must be taken to spray this mixture on and under the leaves.

The big advantage of this product, which is however less effective than the previous ones, is that it is 100% harmless to nature, the gardener and the gardener's children. It just goes to show that grandmother’s remedies still have a future in the organic garden!
