Instead of purchasing multiple, or artificial/chemical, fertilizers we use Epsom salt for everything! It's available in dollar stores. A lot cheaper and simpler than the individual fertilizers for vegetables, flowers, and roses in particular.

It is used in a ratio of 1 tablespoon of Epsom salt to one gallon of water. Fill up your watering cans with it! Epsom salt is made up of magnesium and sulfate, which are both needed plant nutrients. You can start using it when sprouting your garden seeds and continue until harvest!

    For greener grass.


    • one full can of pop (not diet)
    • one full can of beer
    • 1/2 cup dish soap
    • 1/2 cup of ammonia
    • 1/2 cup of mouthwash


    Pour into a 10 gallon hose end sprayer and apply about every 3 weeks. Works really well. People are always asking my husband how he gets the grass so green.

    Homemade Lawn Fertilizer


    Does anyone have a homemade lawn fertilizer?

    There are several homemade lawn tonic recipes that have been around for years. Here are a few variations:

    • 1 can of beer
    • 1 cup of ammonia
    • 1 cup of plain liquid dish soap... (not liquid detergent)
    • 1 cup any brand liquid lawn fertilizer
    • 1 cup of molasses or corn syrup

    Mix these ingredients into a 10 or 20 gallon hose end sprayer and apply evenly to the entire lawn in early mornings or later evenings. Water well. You'll find your lawn will need less water during droughts. Feed every three weeks or year round in warmer zones.


    • 1 can of beer (no "light" beer)
    • 1 can of soda (no "diet" soda)
    • 1/2 cup of liquid soap
    • 1/2 cup of liquid ammonia
    • 1/2 cup of mouthwash

    Or this last one from Jerry Baker, America's Master Gardener:

    • 1 cup of beer
    • 1 cup of baby shampoo
    • 1 cup of liquid lawn food
    • 1/2 cup of molasses
    • 2 tbsp. Of fish emulsion
    • Ammonia

    The beer in these recipes promotes microbial activity (same goes for the tea, soda, corn syrup and molasses). Ammonia breaks down into nitrates, which provide the plants nutrients. This nitrogen also helps break dawn thatch into nutrients the lawn can take up. The soap helps the solution spread more evenly over the lawn as you apply it. And the mouthwash contains alcohol, which acts as an irritant to many insects. Occasionally you may also run across a recipe containing tobacco. This also acts as an insecticide.

    I've never tried them, but these recipes are supposed to work on both your lawn and your flowers.

    There are some recipes for homemade fertilizer on this site. Is this fertlizer safe for pets and kids to walk on right after application?

    You must query the provider of the fertilizer infomation. Note-in a recipe, each ingredient may be safe for children and pets, however, a large amount of any one ingredient or a combination of two or more ingredients may be a problem. I doubt any of the providers can guarantee safety concerns.

    • one can of soda pop (not diet)
    • one can of beer (no light beer)
    • 1/2 cup of household ammonia
    • 1/2 cup of liquid dishwashing soap (do not use antibacterial soap because it will kill important microbes)
    • 1/2 cup of mouthwash


    Mix all these together, in the proper amounts, poured it into a 10-gallon hose-end sprayer, and apply it to a lawn while you water. The pop and beer act as food for the lawn. The ammonia promotes growth and helps make the grass green. The liquid dishwashing soap is a wetting agent and helps the water reach the roots. And the mouthwash actually kills bugs and grubs in the lawn.

    Be very careful with the ingredients. The ammonia could kill the grass if too much is used. The tonic should only be used once every three to four weeks in high heat, and even less frequently when the temperatures are not hot. It is also important to only use dishwashing soap, dishwashing detergent could be harmful. If you have pets at home, they should also be kept off the lawn for 24 to 36 hours after treatment.

    I am looking for a lawn spray you can make with liquid detergent, water, beer, and ? I don't know the other ingredient, the amounts of each to use, or how to use, but heard it works very well. Does anyone know?

    I have lost my Jerry Baker recipe for a spray to get rid of mosquitos. I used it last year and it was great! It used lemon dish detergent, dog flea detergent, and ammonia. Help me!

    Dissolve the Copper Nitrate in water and use on approximately 1000 square feet of lawn. Apply by spray with weed sprayer. Apply 30 days later to kill any new growth or to fertilize the lawn if desired.
