But First…

What is Blossom End rot?

Blossom end rot is a physiological condition that results in a brown and dark spot which starts to appear on the bottom end of the fruit (where the blossom was). This has led to the name “Blossom End rot”. 

This brownish spot takes on a much darker color, particularly as the tomato further grows. In due course, the spot becomes black and leathery. On top of this the spot increases in size, top the point where it can even cover half of the tomato’s bottom area.

If you have experienced this condition before, you can agree that the worse part about Blossom end rot is that the problem appears right before the tomatoes start ripening. In other cases, the disorder can even occur earlier, as soon as the tomatoes start developing on the plants. 

 Sooner or later, the rest of the tomatoes that are on the same plant follow suit- that’s if you don’t do anything about it. 

Ultimately, the lack of calcium is the chief cause of the disorder. But then again, this is only because the plant didn’t receive enough water in order to absorb enough calcium in the first place. So, irregular watering takes much of the blame.  

Besides this, Blossom end rot can also be built up if the tomato plants are placed under the following circumstances. 

  1. Uneven watering

If you aren’t giving your plants enough water, the plants won’t be able to take up enough nutrients (including calcium) in order to keep up with its growth. Eventually, this plant will suffer from Blossom end rot. As such, watering should never be taken lightly.  

  1. The application of fertilizers that are high in nitrogen 

Nitrogen, when applied to the soil, enriches the leafy parts of the plant. On fruity vegetables like tomatoes, however, the application of a nitrogen fertilizer will also lead to the rapid development of the leaves and not the fruits. 

This is because most of the essential nutrients will be averted away from the plant’s fruits. As such, these type of fertilizers work best for vegetable such as lettuce.

  1. Salt-concentrated soils

When the level of soils are just too high in the soil, the roots will be repressed from taking up nutrients to the rest of the plant. This is naturally lead to Blossom end rot. 

For the most part, high levels of salt in the soils are associated with an excess use of synthetic fertilizers. 

  1. Soil pH 

If the pH levels in the solid are either be too high or too low, the tomato plants will be unable to access the nutrients in the soil. 

As such, the plants will suffer from Blossom end rot. Also, the overall growth of the plants will be affected. Normally, tomatoes will flourish on a soil that has an average pH level of around 6.5.
