Chemical weed killers have a reputation for being extremely effective.

And yet, nettle manure is ideal for effectively and ecologically weeding your garden.

Known and very popular with gardeners, this decoction works wonders thanks to its properties.

White vinegar is the ultimate weedkiller for areas not intended for cultivation such as walkways, terraces, and gravel.

It has the advantage of being a contact herbicide, that is, it burns only the aerial parts with which it is in contact.

This prevents it from seeping into plant tissue like commercial chemicals do.
