Before you add fertilizer to your tomato plants, it's best to get a soil test from a garden center. This will help you know exactly which nutrients your soil is lacking.

When you see three numbers on a fertilizer label, like 10-10-10, those numbers refer to the ratio of nitrogen, phosphorus, and potassium in each application.

Look for a tomato-specific fertilizer like Espoma Organic Tomato-tone which has a ratio of 3-4-6. The high potassium levels help the plant produce plenty of healthy fruits.

The best tomato fertilizers include calcium, magnesium, and sulfur, although some options also include beneficial bacteria to boost biological activity

in your soil.

Consider adding compost to your tomato fertilizer, as it can help keep the soil loose while retaining moisture and nutrients and help balance the acidity level in your garden.

A simple method to plant your tomatoes is to use equal parts topsoil, compost, and peat moss. Then, read the fertilizer bag to know the proper amount of fertilizer to add.
