How to Prune Outdoor Yucca

Question

We have a very large yucca plant in our back garden with three main trunks on it. Each trunk has an additional two newer and smaller trunks growing from it. The plant has been in the garden over ten years. After the harsh weather and heavy amounts of snow, the leaves have virtually all fallen off and the top part of the trunk where the leaves are growing from has rotten. Some are black and some are just so soft and squisgy. We will be devastated if the plant cannot be saved, as it is the main feature of our garden. Can it be cut back and will it regrow? I am not a gardener by any stretch, so any help will be appreciated.

Answer 1

I would wait until spring to cut back the plant. It will help protect the new growth, just in case another freeze occurs. These articles will help you as well:
