Consider the following factors before purchasing tomato fertilizer. To begin with, you must select a tomato fertilizer that is appropriate for your plants. If you have a fast-growing plant and wish to fruit faster, for example, you should use a different set of fertilizers.

Things To Consider Before You Purchase Your Tomato Fertilizer

  • Soil type,
  • Soil fertility levels, 
  • pH levels, 
  • Whether or not the soil is organic or treated,
  • Stage of plant growth
  • If the plant is in a pot or in the ground

It's important to know what type of soil your tomatoes are planted. You should consider whether they are in (light sandy/clay soil) or if they require high levels of nitrogen and phosphorus (depending on whether they're fruiting tomato plants).

You'll also need to know what your soil's pH is. You can use a soil test kit to determine your soil pH. Tomato prefers a pH of 6.5-7.

You should also know how much (if any) organic matter is in the soil and whether or not it's high in magnesium.

​For best tomato results, consider using the best tomato fertilizer high in nitrogen (for lush green foliage growth) and the best organic tomato fertilizer high in phosphorus (to encourage flowering).

One of the important things to should consider while buying tomato fertilizer is the soil composition where you plan to grow tomatoes. Before buying any fertilizer, always do a soil test so that it is easier to buy the specific fertilizer lacking in the soil.
