Peach blight is a fungal disease that deforms leaves and can destroy fruit early. In 2021, we planted 4 new peach trees on dwarfing rootstocks. The following year, the blister appeared. As we want to avoid synthetic fungicides, in 2023 we applied a garlic-based infusion in winter.<\/p>\n\n

\"\"
Fishing in June 2023. Despite the garlic treatment in winter, we can see a little blistering: pinkish-red spots, some deformed leaves. That year, we had a lot of peaches. <\/strong>But as there was still blistering, I thought the garlic wasn’t effective. So in 2024, I stopped using this treatment. <\/strong><\/figcaption><\/figure>\n
\"\"
A catch at the end of April 2024. Untreated in winter, by early spring they were all covered in blisters. <\/strong> <\/figcaption><\/figure>\n
\"\"
The invasion was total. In the first shoot of the season, not a single healthy leaf. <\/strong><\/figcaption><\/figure>\n
\"\"
The fruit was also lost, falling off on its own a few weeks later. We didn’t harvest any fish in 2024.<\/strong><\/figcaption><\/figure>\n

<\/p>\n\n

<\/p>\n\n

In the light of this experience, and even if every year is different, it would seem that in the end, the garlic treatment was somewhat effective in 2023. Not absolutely effective, but significant enough to make the effort to do it again this year. This treatment is prepared and applied in February.<\/p>\n\n

<\/p>\n\n

\"\"
The first ingredient: two large heads of garlic or equivalent.Use the lowest quality, heads that are too small, cloves that are too dry or damaged. <\/strong><\/figcaption><\/figure>\n
\"\"
Second and final ingredient: rainwater.Fill a non-metallic container (wood, plastic, terracotta) with around 30 liters of rainwater. Before filling, position the can in a sunny spot as far as possible.<\/strong><\/figcaption><\/figure>\n
\"\"
Coarsely chop the garlic cloves.<\/strong><\/figcaption><\/figure>\n
\"\"
Throw the chopped garlic into the rainwater.Mix with a stick and push a little to the bottom. Most of the pieces will float to the surface, but this is not a problem. <\/strong><\/figcaption><\/figure>\n
\"\"
Then close, but not with an airtight cap, just with a tight cover.Place the can in the sun and leave to infuse, without intervention, for two to three weeks.<\/strong> <\/figcaption><\/figure>\n
\"\"
After two weeks, the infusion has taken on the color of a clear, frothy soup, and is very fragrant.If, on removing the cover the first time, the smell of garlic isn’t particularly strong, close it all up and wait another week. <\/strong><\/figcaption><\/figure>\n
\"\"
Equipment required: basins to hold the 30 liters of infusion, a sieve, a sprayer. <\/strong><\/figcaption><\/figure>\n
\"\"
Pour the liquid into the basins, filtering through a sieve.This is less practical, but you can also filter through a fine-mesh cotton or synthetic cloth.<\/strong><\/figcaption><\/figure>\n
\"\"
If the sieve is tight enough, just filter once and the garlic infusion is ready.<\/strong><\/figcaption><\/figure>\n
\"\"
The chopped garlic is immediately collected and infused a second time, again in 30 liters of rainwater. It will be used in a month’s time. This year’s experiment involves repeating the treatment in March. <\/strong><\/figcaption><\/figure>\n
\"\"
To apply the treatment to the trees, watering cans and sprayers are filled.<\/strong><\/figcaption><\/figure>\n
\"\"
In February, the structure of the leafless peach trees is clearly visible. The garlic infusion is sprayed along the entire length of the branches and trunk, going over both sides.<\/strong><\/figcaption><\/figure>\n
\"\"
Concentrate on branch tips and buds, spraying several times without skimping on quantity.<\/strong><\/figcaption><\/figure>\n
\"\"
Finally, sprinkle garlic infusion generously around each tree, at least 5 liters, more if available.Repeat the whole operation around the beginning of March.<\/strong><\/figcaption><\/figure>\n
\"\"
After that, we can only hope that the trees will be as healthy as they were in 2023. <\/strong><\/figcaption><\/figure>\n
\"\"
And harvest different varieties ofpeaches<\/strong>again.<\/strong><\/figcaption><\/figure>\n
\"\"
The most spectacular is the sanguine, a late variety to be harvested at the end of August.<\/strong>Under its thin skin, it is blood-red.<\/strong><\/figcaption><\/figure>\n
\"\"
The flesh is melt-in-the-mouth, very juicy and fragrant, with a hint of bitterness at the end. <\/strong><\/figcaption><\/figure>\n
