Uses of fermented stinging nettle tea

Use of fermented stinging nettle tea as a pest repellent

Fermented weed tea prepared from such stinging nettle.Spray on plants directly with a sprayer to use it against parasites. No dilution required, if the ratios above are followed.

The fermenting releases several acids from the fresh plant, as well as a special type of lectin protein. Acids and lectin are key ingredients in fending off aphids, since lectin interferes with their development cycle.

With this same dosage, you can also soak soil mix and let it dry off. This will help seedlings resist damping off after sprouting.

Use of fermented stinging nettle tea as fertilizer

Thin with water (10 to 20% tea-to-water ratio) and pour it on the ground as you would liquid fertilizer.

  • With this diluted ratio, the weed tea won’t have much effect on pests and fungus, so there’s no point spraying leaves. In fact, wetting leaves if the weather is hot might even trigger bouts of mildew.

Thanks to this mixture, you save on expenses and protect the environment, too.

In the good old days, a fistful of stinging nettle leaves was placed at the bottom of the planting holes when transplanting tomato seedlings to boost tomato harvest.
