Can blossom end rot be caused by lack of moisture?
A. Yes, a failure of moisture reaching tender tissues at blossom end. Due to lack of rainfall, droughty soil, or alternating dry and wet spells. Can occur because there is not enough oxygen in the soil for proper moisture intake. Control by any measure that ensures adequate water supply – such as irrigation, watering the same time each day, maintaining organic matter in the soil and in some cases improve the drainage.
