Hollow Heart of Cucurbit Crops
Return to Physiological and Nutrient Disorders
Hollow heart is the formation of a hollow cavity inside some cucurbit fruit, especially melons. This disorder can result from a number of factors, including low boron levels, genetics, and uneven water management. Although not outwardly visible, hollow heart makes fruit unmarketable.

Management:
- Avoid varieties with a tendency to exhibit hollow heart.
- Ensure that boron levels in the soil are adequate before planting and be careful not to overfertilize.
- Follow recommended plant spacing.
- Provide consistent and proper irrigation.
