Selection has helped to solve the problem of eggplant bitterness only partially.
Growing modern varieties reduces the risk of getting bitter fruits, but much still depends on the care of the plant.
If you make a mistake, even hybrids will make you wince. So it's not about the variety, but about the care.
Even old varieties can produce edible fruits if you follow a number of subtleties of growing eggplants.
1. The scorching rays of the sun can increase the percentage of bitterness. It is better to shade eggplants during very hot periods.
2. Calcium deficiency also leads to the harvest having to be thrown away. Complex fertilizers completely solve this problem.
3. In hot weather, it is important not only to shade, but also to water eggplants regularly. If the plant suffers from drought, bitterness is guaranteed.
4. It is necessary to harvest regularly. Overripe fruit will taste bitter even if all growing conditions are met.
