Stem Splitting of Cucurbit Crops
Return to Physiological and Nutrient Disorders
Stem splitting is most often observed in transplant production when temperatures are low or when there is a period of rapid growth resulting from high temperatures, increased irrigation, or high fertility. In minor cases plants can be transplanted with few ill effects; however, in severe cases seedlings should not be transplanted if possible.

Management:
- Prior to transplanting, provide warm, uniform temperatures for seedlings to help prevent uneven growth during transplant production.
- Once plants are in the field, provide consistent irrigation and fertilization.
