Composting provides one of the best and least expensive ways to fertilize your tomatoes; use yard clippings, eggshells, overripe fruit and anything biodegradable. Avoid using things like meat and grease. Before putting your compost with your tomatoes, check the pH level. A good level of pH ranges between 6.0 and 7.0. Composting keeps the moisture level even at the roots.
Liquid Tomato Fertilizer
Once you have an established tomato plant, use a liquid fertilizer, which has a fast release and quickly replenishes the lost nutrients. Blended with fish kelp, nitrogen, phosphorus and potassium, this type of fertilizer is ideal for tomato plants. Buy liquid fertilizer at any major lawn-care provider. The only drawback to using liquid fertilizer lies in the fact that you need to reapply the fertilizer often during rains or prolonged dry spells.
Tomatoes Alive is specifically designed to give tomatoes what they need. It releases some nutrients quickly to start the plant and keep it healthy when it is young and becoming established; it releases other nutrients slowly to avoid root damage. (Also, as the plant matures, it does not need nutrients as quickly.) Home Improvement Time studies proved that tomatoes grown with Tomatoes Alive produced 150 percent more tomatoes than plants with no fertilizer.
Tomato Tone is an all-natural product made from plants and other natural products. Use this type of fertilizer on transplanted or mature plants. You only need a handful of fertilizer sprinkled around the plant. Tomato Tone has a special formula with more than three million microbes that benefit to the roots, keeping them strong and healthy. According to Veggigardener, tomatoes grown with Tomato Tone grew bigger and faster than those without, and they produced more tomatoes than did plants with no fertilizer. This blend contains 3 percent nitrogen, 4 percent phosphorus and 6 percent potassium; all of which are essential to growing good healthy tomatoes.
