What to do if tomatoes have a yellow spot near the stalk: a simple solution to the problem
The yellow spot on the top of the fruit, also called the "yellow crown" or "yellow top," can of course be a characteristic of the tomato variety.
However, most often, according to the expert of the online publication BelNovosti, scientist agronomist, landscape designer Anastasia Kovrizhnykh , such a mark is a sign of a lack of a certain nutrient, namely potassium.
What is especially annoying is that the yellow spot indicates that the fruit is not ripening evenly, remaining hard and unripe at the top.
Timely fertilization with fertilizer containing potassium will help solve this problem.
To do this, fill a 10-liter bucket with water and add 10 grams of potassium sulfate to it.
Use the resulting solution for watering at the roots - one bush will need 1-2 liters of nutrient solution.
The exact amount of fertilizer depends on the size of the bush and is also determined by the severity of the problem.
That is, if the yellow spot takes up half or more of the tomato, then you will have to pour out 2 liters; if less, then one liter.
Do not forget that you should apply fertilizer to pre-moistened soil.
