How to Make Organic Tomato Fertilizer


In order to grow delicious, plump healthy tomatoes, it is important to use some sort of fertilizer. If you want to ensure that your tomatoes are organic and grow without the chemicals of store-bought fertilizers, concoct your own at home. People use a wide range of organic tomato fertilizers, from rabbit droppings to seaweed. But there are also easier things to obtain that you can mix together to add to the tomato plants, such as eggshells, coffee and human hair.

Step 1

Obtain a large container from a hardware store to hold the natural fertilizer, like a 5-gallon plastic garbage can with a lid. Create 4 cups of organic tomato fertilizer per transplanted tomato plant. Mix and store it in the large container.

Step 2

Insert the organic component of human hair (or animal hair from dogs or cats) when planting the tomato plants, down in the bottom of the hole. Hair contains sulfur, keratin and nitrogen that will slowly release into the soil while the hair is breaking down, providing essential nutrients to the roots of the tomato plant. These nutrients slowly release into the soil as the hair breaks down. Animal hair may be easier to use as you can just brush your pet and add the hair when necessary. Add a thick ball of the hair, spread around the bottom of the hole, then plant the tomato plants.

Step 3

Crush up 2 cups of eggshells per tomato plant. Eggshells provide calcium and nitrogen. After you crush up the eggshells, place them on a sunny window sill to dry out for a couple of days.

Step 4

Prepare the organic coffee grounds. Lay out 2 cups of coffee grounds per tomato plant, used or unused, on a paper towel on a sunny window sill for a couple of days as well, or until completely dried out. Mix the eggshells and coffee grounds together thoroughly. Sprinkle a thick layer around the base of the tomato plants, making sure it has contact with the plant. Use all 4 cups of the mixture, then water generously to ensure that the fertilizer sticks and absorbs into the ground.
