Q. My little pummelo which came bare root in March has profuse flowering now in November. The tree is small -5'- and would not support any pummelo sized fruit. Should I wrap it up for the winter and disregard the flowers?
Pomello is a distant relative of grapefruit and enjoyed in many SE Asia countries like on our farm in the Philippines. Its tolerance to freezing temperatures is better than most limes but not as good as some oranges. Its chilling injury (refrigerator temps, think banana) is not well known but suggests it may exhibit chilling injury. Pomello grown in the Las Vegas area.
A. In this particular case I don’t think any of the flowers would have set fruit anyway. Pomello that I know takes about six years to bear fruit. It may flower earlier than this but the fruit have to be pollinated and not abort the fruit.
Yes, protect the tree this winter if there are threatening temps below freezing.
I don’t know about chilling injury (temperatures not freezing but refrigerator like) to this fruit tree but there are some suggestions that it exists.
