Splitting Grape Berries
Commonly affects: Vitis vinifera, V. labrusca (Grape)
Cracks appear in the berry skin, especially after rain following a dry period, sometimes leading to secondary rot in the split fruit.
Potential Causes
- 1Inconsistent watering or rainfall â a dry spell followed by heavy rain causing rapid, uneven expansion
- 2Thin-skinned varieties being more prone to splitting than thick-skinned ones
- 3Overripe fruit left on the vine too long
Solution Steps
- 1Maintain even soil moisture through irrigation during dry spells approaching harvest
- 2Harvest promptly once fruit reaches full ripeness rather than leaving it to overripen
- 3Choose split-resistant varieties for regions with unpredictable rainfall near harvest
- 4Remove split berries promptly to prevent secondary rot spreading to healthy fruit
Prevention Tip
Consistent irrigation through dry spells before harvest, rather than letting vines rely entirely on unpredictable rainfall, significantly reduces splitting.
