Tomatoes are heavy feeders. Once they begin producing fruit they need extra nutrients, even if you added compost to the soil at planting time.

Enter fertilizer. Most fertilizers are a combination of the three nutrients commonly fed to plants: nitrogen, phosphorus, and potassium (referred to as the “N-P-K ratio”). The three numbers represent those three nutrients.

The first number represents the proportion of nitrogen in the fertilizer. Nitrogen encourages leaf growth (rather than blossoming or fruit development.) In tomatoes, excess leaf growth discourages blossoms and fruit. A lower number of nitrogen in this fertilizer is a good indicator that it is suitable for midseason tomatoes.

Phosphorus (the second number in the N-P-K ratio) encourages flowering, and therefore fruiting. This benefits midseason tomato plants.

Once a tomato plant starts flowering and fruiting, it needs a higher ratio of potassium for fruit to develop (the third number in the N-P-K ratio). The strong third number in this fertilizer indicates that it will help tomato plants produce healthy, quality fruit mid- to late season.
