Organic tomato fertilizer feeds the soil as well as the plants. Make your own homemade tomato fertilizers from common household items. Tips for making tomato feed, liquid tomato food and tea feed fertilizer for tomatoes.
You can buy organic fertilizer for tomato plants in several forms. There are granular products, liquid tomato feed, and powders like horticultural lime, bone meal, and blood meal.
The thing that differentiates organic tomato fertilizers from inorganic tomato food is that it is made up of materials which used to be alive.
When you use organic fertilizers you are not just feeding your plants, you are feeding the microorganisms in your soil. Any time you add organic matter to the soil you are laying out a buffet for the earthworms. This encourages them to multiply. Their tunnels aerate the soil and their castings are a wonderful tomato garden food.
You can make your own tomato fertilizer by mixing a few organic fertilizers together in equal amounts.
Tomatoes like a formulation of 1 part nitrogen to 2-3 parts phosphorus to 1 part potassium.
Mix together a cup of each, sprinkle in a teaspoon of Epsom Salts for magnesium and sulfur and a tablespoon of horticultural lime for calcium. Calcium prevents the tomato disease blossom end rot. The Epsom Salts promote stem strength and fruit set.
If you want to add more potassium to the mix, dry a few banana skins on a cookie sheet in a slow oven until they are crisp and brown. Crunch them up after they cool and add them to your homemade tomato fertilizer.
You can tea feed tomato plants with compost tea. Place a bucket of water outside in the sun. Drop a fistful of organic compost or composted manure into it. Stir it with a stick and then let it brew for a few days. Pour it around the tomato vines.
If you have a fish tank, save the dirty water when you clean it. It makes a potent liquid tomato fertilizer.
When you have leftover coffee (black--it can have sugar but no cream) dilute it in a pail of water and use it to water tomatoes growing in pots or in the ground. It will give them a nitrogen boost.
That last little bit of molasses that you can't pour out of the jar makes a fine fertilizer for tomatoes. Pour hot water into the jar, shake it, and you have a sweet liquid tomato feed. All different types of tomatoes love the sugar and minerals in molasses.
