Q.Can We Repair The Trunk And Bark Of A Yucca Faxoniana?

Zone 79902 | Anonymous added on March 31, 2021 | Answered

There are holes on the lower trunk. Started with one about 3″ in diameter which extended about 2″ inside the trunk. Then, two more appeared connecting to the first hole. All are in the same area. We’ve seen a woodpecker on the trunk and suspect bugs. We’d like to keep this tree. I found several 1/2″ by 1/16″ opaque larvae inside the chewed on webby soft dark black clusters inside the trunk. They had tiny dots of dark material inside their gullet from chewing on the trunk,…I guess. The inside of the tree looks like fibers or webs where it is being pecked at by the woodpecker. Thank you.

Using a clean knife, cut away all the damaged tissue, including some healthy tissue, from the area and let it heal on its own.
