Cantaloupe squished out overnight
Picked off my vine a solid full mature canteloupe yesterday, placed it on the kitchen counter and this morning found it sort of exploded into a nasty sloppy mess spewing fruit and seeds all over the counter.
Knox County Tennessee
Soft fruit rots are pretty common on cucurbits like muskmelon. It may be something like Rhizopus fruit rot, a soft rot that enters through stem scars. It's extremely important to cool melons as fast as possible after picking to keep these rots at bay. Leaving a melon on the kitchen counter, even overnight, gives these post harvest rots time to do damage internally.
Hope this helps.
