Symptoms and their Causes
Hard green areas on the ‘shoulder’ of the fruit: This is known as greenback. These areas remain hard and unpalatable as the rest of the fruit ripens. The causes are usually excess light, high temperatures, and/or insufficient feeding.
Blotchy ripening and internal areas of white or yellowish tissue: Known as whitewall, the causes, as for greenback, are usually excess light, high temperatures, and/or insufficient feeding.
Black sunken area at the bottom of the fruit: Calcium deficiency in the fruit, usually caused by irregular watering.
Splits and cracks in the fruit: Usually caused by variable water supply.
