Growing organic tomatoes require good soil, enough sunlight, adequate watering and of course, fertilizer. In general, there is really no single best organic tomato fertilizer because this plant is not very picky. But since your are cultivating organic tomatoes, your must also use organic fertilizers instead of the commercial variant.

Tomato plants require a lot of nitrogen, phosphorus and potassium in order to produce lots of leaves and fruits, and to fight-off diseases. Organic tomato fertilizers are full of micronutrients that are essential for the plants' growth.

You must look at the nitrogen, phosphorus and potassium ratio of the organic fertilizer that you want to purchase - it should be at least 8:10:10 or 10:10:10. Purchase natural and less-refined organic fertilizer; or composed if you know an organic tomato fertilizer recipe.

Manure - This organic fertilizer is old-school and it uses excrements from grass-eating animals. Try not to use your pet's excrements because those are nigh in pathogens and toxins that are harmful to your tomato plants and to your health as well. Horse or cow manure are the best choices and they should be aged or composted first.

Fish emulsion - You can either buy or make your own fish emulsion. Combine fish parts or canned fish with carbon-like sawdust and let it decompose.

Blood and bone meal - This may be new and weird to you, but the combination of animal blood and bone is a great source of nitrogen and phosphorus. This is available in garden stores.


Weeds and grass clippings - Anything green in the garden is a great source of nitrogen and this includes grass and weeds too. You must first compost the weeds in order to destroy the seeds.

Seaweed - Although low in nitrogen, phosphorus and potassium, seaweed is a powerhouse of 60 trace elements that tomato plants love.

Alfalfa meal - Alfalfa is high in nitrogen, phosphorus and potassium, and it is also full of micronutrients and hormones. Alfalfa meal usually comes in the form of hay bales or rabbit food.

Whichever organic tomato fertilizer you choose, the goal is to combine at least two types for optimum growth and development. There are tomato farmers who pamper their plants in a good way by using the best combination of organic fertilizers.
