Instead of expensive fertilizers: Use home remedies made from waste products to get your garden ready for spring. Coffee grounds are rich in potassium, nitrogen and phosphorus and at the same time attract earthworms that loosen the soil.
Crushed eggshells can be used as a natural fertilizer for plants as they contain valuable nutrients. Potato water contains substances such as potassium, magnesium, phosphorus and iron that are ideal for fertilizing. Kitchen scraps such as rhubarb leaves and banana peels should not be thrown away as fertilizers.
