Blotchy Ripening of Solanaceous Crops
Return to Physiological and Nutrient Disorders
Blotchy ripening can be caused by a number of factors, including inadequate potassium availability, cool and cloudy weather, and moisture stress. If blotchy ripening is a persistent problem, soil testing is recommended and check the Hartz Ratio (included on UK soil tests for tomato production). Applications of potassium nitrate during fertigation may help. Some tomato varieties are more susceptible than others.
