“Are your tomatoes rotting on the vine, and your neighbors are collecting them in buckets?
Perhaps you yourself are poisoning them with “healthy” fertilizer!
Tomato Weekly magazine shocked readers with data: 9 out of 10 gardeners sprinkle fertilizer under tomatoes that blocks calcium absorption.
Agrochemist Dmitry Solovyov stated:
"This product is the number one cause of blossom-end rot. You buy it in every store!"
We studied a report from the University of California and found 3 killer fertilizers that turn your tomatoes into poison.
Fresh Chicken Manure: Hell for Roots
Ammonia in fresh manure burns the roots and causes greenery to grow instead of fruit.
A 2023 study published in the Journal of Plant Nutrition found that tomato yields dropped by 55% with this type of feeding.
"I fertilized with chicken feed and got giant bushes and rotten tomatoes!" writes Tatyana from Samara on the "Tomato Fever" forum.
Potassium chloride: a hidden disease provocateur
Chlorine disrupts the water balance of plants, making them vulnerable to fungi.
Professor Igor Kovalenko from Moscow State University warns:
"Chloride fertilizers are good for beets, but they kill nightshades."
Gardeners' World magazine called them "silent taste killers."
Dolomite flour: a false friend
Excess calcium in dolomite blocks the absorption of phosphorus, which is necessary for fruiting.
An experiment by agronomists from Italy (2022) proved that adding dolomite flour to tomatoes reduces the sugar content of the fruit by 30%.
“I added flour to prevent rot, but the tomatoes became sour, like lemons!” complains Oksana from Kyiv in the Facebook group “Tomatomania”.
Conclusion
"Tomatoes are not a waste bin for fertilizers! If you are still sprinkling "old-fashioned" products under them, stop immediately. After 2 weeks of proper fertilizing, the bushes will come to life.
