GSC Organic Tomato Fertilizer, Tomatoes Alive! and Tomato-Tone Organic Fertilizer are good fertilizers for tomatoes, according to Veggie Gardener. Homemade compost tea is also beneficial for tomatoes, although it is not technically a fertilizer.
Tomato-Tone Organic Fertilizer is a dry product that contains essential nutrients. This fertilizer is especially useful during tomato transplantation. A similar product, Tomatoes Alive!, promotes effective photosynthesis and sturdy root development. Two yearly applications are usually sufficient because this fertilizer releases its nutrients over time.
Compost tea is a homemade liquid made from water and compost. After straining, the tea contains all of the beneficial nutrients that were in the compost. Making compost tea involves placing 2 1/2 gallons of aged compost into a clean bucket, filling the rest of the bucket with water, and straining the mixture after several days.
