Flower food is available in most stores and contains a combination of acidic and carbohydrate components. This food keeps the potted or in-ground flowers healthy even when the soil may be lacking in nutrients. Homemade flower food contains the exact same components but is made from items you have around your house. Making flower food is economical as well as effective. Once you procure all the supplies, they should make at least 20 batches of the homemade flower food.
Rinse out a gallon jug with warm water. It's best to use a new gallon jug for making flower food, but you can use an empty milk jug as long as it's rinsed completely clean of residue.
Add 1 tbsp. of Epsom salts, 1/2 tsp. of ammonia, 1 tsp. of table salt and 1 tsp. of baking powder to the clean gallon jug.
Fill the gallon jug with warm water, stopping an inch or two from the top. Screw on the cap and shake the homemade flower food to combine.
Water your flowers with the flower food, drenching the soil in each plot or pot. Repeat the treatment about once a month to ensure the flowers remain healthy and vibrant. Store the remainder of the flower food recipe in a dark, cool place if you have some left over.
