Top 5 Organic Garden Fertilizers

When it comes to organic gardening, the options for all natural fertilizers can often be a disappointment on the shelves of your local store. Those that are available might be very expensive and while they are labeled organic on the packaging, you really don’t know what’s made in them. Well-nourished plants are healthier, more beautiful and more reproductive. Plants need to be fertilized because most soils don’t provide the crucial nutrients required for a healthy growth. When you are lucky to start gardening with the most fertile soil, as your plants nourish, they absorb nutrients and this leaves the soil less fertile. There are 6 main nutrients that most plants require; oxygen carbon dioxide and hydrogen which plants gets from water. The other 3 are potassium, phosphorus, and nitrogen that are acquired from the fertilizers.
