Many chemical lawn fertilizers are available commercially, and most come with warnings about not getting the fertilizer on your skin or in your eyes. Avoid potential chemical hazards by creating your own liquid fertilizer that can be applied with a common garden sprayer. Making your own lawn fertilizer eliminates any health risk, while providing your lawn with extra nutrients.
Mix 16 tbsp. Epsom salt and 8 oz. ammonia in a jar until the salt dissolves.
Pour 2 gallons of water into a garden sprayer and add 2 tbsp. of your liquid lawn fertilizer concentrate. Mix them together.
Spray the mixture across your lawn. This will cover a space of 200 square feet. To cover 400 square feet of space, use 4 tbsp. of concentrate with 4 gallons of water, and so on.
