Healthy, well-ripe tomatoes depend on the kind of fertilizer you utilize, and how and when you utilize it. Tomatoes, like other annual crops, are heavy feeders, and they require a lot of nutrients. If the tomatoes are not fertilized, they won`t be very healthy or juicy. On the other hand, fertilizer can lead to poor tomato production, therefore knowing how frequent to feed your plants is essential.

Usually, specialists recommend that you use approximately 3 pounds of complete fertilizer to the plants while preparing the land for planting, which is supposed to be dug to up to 12 inches deep. This will warranty that the beds are full of nutrients, a vital step in producing healthy fruits.

After the first plant has grown to be approximately the size of a golfing ball, you can add some more fertilizer, which will stimulate tomato production. Then, you can add some light fertilizer weekly or after two weeks until the harvest time ends. Do not get the fertilizer on the plant leaves and always make sure that the tomato plants have been watered adequately before applying the fertilizer.

Tomato Fertilizers Ingredients

When it comes to deciding the kind of fertilizer to go for, search for several essential nutrients. They include phosphorus, potassium, and nitrogen. However, you should avoid tomato fertilizers with high nitrogen content, since it can have the plants become bushy but produce small or no fruit. Nitrogen boosts leaf growth. Potassium aids the plant to swiftly develop, while phosphorus is essential for the growth of the roots and flowering as well.

Calcium kills hazardous matters in the soil and gets rid of plant diseases like rot. Magnesium normally collects sunshine, which aids the plant and the fruit to grow while sulfur helps the general growth of the plant.

Tips for Correctly Fertilizing Tomatoes

Natural vs. Synthetic Fertilizers

Natural fertilizers are made from organic products that are either sourced from plants or animals, while chemical or synthetic fertilizers have phosphorus, potassium, and nitrogen. Typically, if your soil has plenty of natural fertilizers, you might not require a chemical fertilizer. Although, you can side-dress the crops using a balanced fertilizer, if necessary. At the end of the day, it`s up to you to choose whichever kind of tomato fertilizers you see fit.


Honestly, fertilizer is void if your tomato plants will not be able to absorb the nutrients placed in the soil. To guarantee healthy roots, it is vital to ensure you water the plants adequately. Water gradually and deeply at the plant`s stem, granting enough time for the water to access the soil. Always water the crops early during the day. Usually, tomatoes need 1 to 2 inches of water every week. Probably more than most vegetables, tomatoes depend on correct planting so that they offer you lots of fruit all through the summer.


Go for a constant-release fertilizer, which will aid in giving the nutrients your plant will require to produce the healthiest harvest.
