My Yucca Looks Like It Has Rotted
When my yuccas (2 of them in different areas) started to come alive this year, they had dried dead leaves and now look like they are rotting. They are outdoors and have been as long as we have had them. Why?

Rotting leaves are generally a sign of too much water. Other than cutting away these leaves, I would back off on any watering. Yucca plants do not respond well to a lot of water. They prefer dry situations with only occasional water.

It could also be weather related. We have had very weird weather across the US., with unseasonably warm temps one day, cold the next. These fluctuations can easily damage plants. This article may help: https://www.gardeningknowhow.com/ornamental/foliage/yucca/yucca-cold-weather.htm
