It's a bit hard to tell from the photo, but the butterfly ginger growing tip/shoot is stuck in the previous fold. It keeps growing and forms the loop you can see in the photo. The next shoot does the same, and I'll get a plant with two or three loops. This is happening right now with about 10% of the gingers in this patch. I don't know if it's caused by a lack of water, too much water, or something else. It happens every year, and I can pull out each looped shoot and free it, but the leaves/shoots tend to get shredded in the process.
Any ideas about this problem?
