I also make my own fertilizers, although I use kitchen scraps. Only vegetable and fruit waste. All this has a lot of nutritional value in it. Make sure to use them thoroughly before throwing them away. I do it as described in the article https://totemat.pl/jak-zrobic-nawoz-do-kwiatow-w-domu-najlepszy-nawoz/, i.e. heated in water, and then water the plants with this water (after cooling down, of course).
