Many gardeners are heavy-handed when it comes to fertilizer, reasoning that the more nutrients a plant has available, the better it will thrive. Unfortunately, for many plants, excessive fertilization can lead to problems ranging from the burning of sensitive roots to death, especially for cacti. In tomatoes, fertilizing is a double-edge sword, because if there are too few available nutrients in the soil, plants suffer from diseases or are too weak to produce fruit, but if there are too many, your plants will see explosive vegetative growth, but few flowers and fruits.
Tomatoes are vining plants that thrive in the warm sunshine and temperatures of summertime gardens. Although these plants will grow on their own, they do better with the right fertilizer, water and location.
Location
All tomatoes require the right location, first and foremost. Tomatoes do best in areas where they get full sunshine for at least eight hours a day, as they will not bear flowers or fruit in shade.
Prospects
No amount of fertilizer will increase a variety's bush or fruit size, though the added nutrition will increase the health of the plant and its fruit harvest.
Importance of soil testing
Fertilization isn't a one-size-fits-all situation, as every garden, even in the same town, has the potential to be drastically different. For example, years of being downwind from a maple tree may cause a garden to have significantly richer soil than one a few blocks away. Even the local soil inhabitants such as worms, soil bacteria and fungus can cause differences in ultra-localized areas. As an added bonus, properly fed tomato plants have demonstrated in many studies to have superior flavor over improperly fertilized fruits. Home soil test kits will help you determine how to properly feed your garden plot and are both simple and effective.
Under-fertilizing tomatoes
Tomatoes suffer a wide variety of symptoms when under-fertilized, many initially appearing in leaves. Nitrogen deficiency causes pale green leaves and weak growth, either systemically or starting near the bottom of the plant and spreading upward. Purple leaves are often caused by too little phosphorus. Yellowing leaves with greenish veins result from a lack of potassium, iron or magnesium. The common physiological disorder known as blossom end rot results from too little available calcium in the soil.

Over-fertilizing tomatoes
Too much fertilizer, especially nitrogen, will interfere with the ability of tomatoes to produce fruit. Excess nitrogen early in a tomato's life leads to explosive growth that is often thin and fragile, with few blooms developing or mature blooms dropping before setting fruit. An excess of fertilizer salts can also damage roots, causing the margins of leaves to yellow, dry out and curl. The fruits of an overly fertilized tomato may fail to ripen in a timely manner or crack while still on the vine.
Proper tomato fertilization
Tomatoes demand soils that are moderately fertile, especially where nitrogen is involved. Unless your soil tests indicate that your soil is nutritionally low, there is no reason to fertilize before you plant your tomatoes in the spring. Instead, wait until standard-sized fruits are about an inch in diameter to fertilize the plant. Apply a 10-20-10 complete fertilizer at this time and again every 4 to 6 weeks while the plants are producing heavily.

Location
All tomatoes require the right location, first and foremost. Tomatoes do best in areas where they get full sunshine for at least eight hours a day, as they will not bear flowers or fruit in shade.
Soil
Tomatoes enjoy rich, acidic organic compost in their soil and should get starter fertilizer at planting to help boost their initial growth.
Maintenance
Tomatoes require ongoing feedings to grow to full, healthy maturity. With monthly fertilization, tomatoes will increase their foliage and produce bright blooms. Gardeners should increase their fertilization and watering when tomatoes begin to bloom, to give tomatoes additional resources for growing fruit.
