Question: an organic herbicide

I would like to know if there are natural products to remove clover and other weeds from a lawn garden.

Answer: a biological herbicide

Dear Francesco,
most of the selective herbicides that can be used on the lawn are harmful to health and very polluting (especially if used in doses not suited to their purpose); there are recent researches that show how particular vegetable flours, rich in proteins (therefore gluten) are able to inhibit the development of weeds, leaving most lawn plants healthy (except the toprost). There are Italian companies that market this herbicide, which also works as a fertilizer, as it also contains good amounts of nitrogen. The Green Agri company, based in Bari, sells many products for organic farming and integrated pest control, and also has this type of herbicide in its catalog; this product is not harmful to humans and animals, but there are some plants that are more sensitive than others, so you should try to ask producers if this product is suitable for your lawn, consider the weeds that grow there, but also the seed mixture you used to prepare the lawn.
In general, a well-tended, watered and fertilized turf tends to develop few weeds, because the small grasses used to make the turf tend to suffocate the other plants, and to shade the seeds.
Clear that, a better effect is obtained with a good quality of the starting seeds, abundant waterings and not too frequent, often give a good result, without the need for many herbicides. To improve the appearance of the lawn, and also to contain the weeds, it is advisable to carry out, at least once a year, aeration, with removal of the felt, which tends over time to distance the tufts of plants that make up the lawn, leaving space for seeds and roots of weeds. In addition to this, it is advisable to repeat at least every two years a light risemina, after the aeration, in order to constantly thicken our turf.
