There are a lot of fertilizers on the market, but they all have one thing in common: chemicals. Chemicals aren't necessary because there are so many ingredients in your home that can supply the same nutrients to the soil. This organic approach is better for the plants, the environment and your pocketbook.
Pour 2 cups of tap water into a large pitcher and let it sit overnight to dissipate chlorine that may be in the water.
Add 1 cup of beer to the water to increase the microbial action in the soil.
Pour 1 cup of Epsom salt in the pitcher and mix it until the salts dissolve.
Finish off the homemade liquid fertilizer with 1 cup of ammonia to increase level of nitrogen, which is something that all plants need to grow.
Pour the homemade liquid fertilizer into the plant's soil or over patches of grass. Apply 4 tbsp. for large potted plants, 3 tbsp. for medium-size plants and 2 tbsp. for smaller plants. This amount of mixture should cover more than 400 sq. ft. of area at the prescribed application rates.
