Should You Keep Avocado Trees That Froze to the Ground?

Even cold-hardy varieties (Monroe, Lula) are damaged by sustained freezes. Regrowth from roots on grafted trees will be from the rootstock, not the desired variety. Fruit production unlikely soon, and same freeze risk remains. Not worth the risk for table fruit—consider replacing with more cold-tolerant species or protecting in containers.
