I have some old Babaco's that bore well..but they got overgrown after nearly 10 years by trees..so I moved them last summer. We had freakish cold two nights in December-before they were dormant and they were killed from 10' to 3'.
Now, back when they were in sun and bore papaya's the problem I had was the fruit took a long time to develop,they were large fruits, and right about the time they should have been ripe by my guess-January,we are well into our cold rainy season. Every year I would lose some to rot,or a blustery storm easily snapped stems with fruit. In a very mild winter I would get fruit that were blaw in flavor-but the tree's look great!
