blossom end rot it is a problem that easily happens to those who grow tomatoes in the garden, it manifests itself in the fruit, where rotting is observed in the final part of the tomato (the tip).

Jokingly, blossom end rot is also called p’s “black ass” homodorus a saying so widespread that it can almost be considered a technical term of agriculture.

The tomato is a plant subject to several diseases, such as mildew, which can be disastrous. Fortunately, blossom-end rot, on the other hand, represents a less serious adversity and a simpler solution, as we will discover. However, if the “black ass” is overlooked can still completely ruin the harvest .

We are talking about a physiopathy and not a disease . The affected plant is not actually diseased but is simply suffering, usually from a disease problem. calcium deficiency .

Severe blossom end rot

First a little summary dedicated to those who read this article in front of a half-rotten tomato plant and wonder how to cure blossom end rot.

My advice is to read until the end, because understanding the causes of the problem not only helps to solve it but to prevent this from happening again in the years to come.

Generally, blossom end rot of tomatoes is caused by calcium deficiency in most cases we can solve it by providing the plant an organic fertilizer with a high calcium content .

However, in many cases calcium is present in the soil, but the plant cannot absorb it properly . Therefore, calcium intake may not be very effective or only useful in the short term.

Therefore, if we really want to cure the “black ass”, we must identify the precise cause of the non-absorption. Often the reason is related to water: water deficiency, excess or imbalance these are triggering factors, as we will see later.
