There are a lot of advantages in using homemade fertilizers on your garden. It is practically free, since you are re-using materials that you already used or recycling materials that you don’t need any longer. You can also get these materials for free from family and friends or neighbors or even in bags on the street when people put out yard clippings and leaves in trash bags on the street to be collected. You can also sometimes get manure from local farmers for free, or for very low cost if they deliver it to your home.
