Fruit problem · common pattern reported by gardeners · verify locally
What you'll see

Most common causes
- Sudden water uptake after dry spells makes fruit swell faster than skin grows
- Irregular watering — soak and drought cycles

- Overripe fruit left on the vine
How to fix it
- Harvest before full ripeness when cracks start
