A couple of things come to mind. Maybe you have a leak in you system as you mentioned. Or, if you're watering and your bananas have not been needing water because they slowed down in cooler weather, maybe they were just using less water relative to other plants (whatever you have nearby) if they are less subject to slowing down in cooler weather. Do you have a neighbor behind your fence/wall who could be watering in that area and causing it to come onto your property? If the soil is heavier there it can retain water more than some of your other nearby soil. I hope you get it figured out as the bananas can grow back quickly in warm weather and fill that area back in pretty quickly.
Good luck!

Thanks for the great information. I have exposed the pipe riser to riser. I am giving it a week to try to dry. If I do not see a pipe leak then it could be from the neighbor. The spot is at the base of a big hill. The soil is a mix of mulch that is applied several times per year (the mulch breaks down fast), sand and garden soil. I amend the soil where I put plants. Thankfully, I do not have clay soil! Are there banana pests that rot out the corm? I have three Guava trees (10 years old) to the left and Heliconia and variegated Ginger (8 years old) to the right. I did cap the drippers during the winter and the plants still had leaves turn yellow and then slowly each leave above the next truned yellow and then the plant fell over. The base was rotted.
Any other ideas?? THANKS!
