Yucca stalks chewed/gnawed?
I am worried about our mature yucca trees. The stalks look like they are being chewed on rapidly, since they fall off green and there is no rotting. They flowered in the last few years, and I don't notice any signs of bugs, but I want to be on the safe side. Any indication of pests like weevils, or maybe just some critter living up in the tree?
There are a few different pests that may be the issue.
