Yucca


Anonymous added on January 27, 2014 | Answered

We're having a dry season this summer in Auckland. One of my Yuccas is potted with cactus mix but is looking very sick. There's quite a lot of what looks like yellow mold. When the leaves are dead, I strip them off but I'm noticing it's starting in circular shapes and spreading. Most worrying is the center top, which is detaching itself and the leaves are fanning out blunt and square. How can I help the plant? I've been known to over water my money tree,s so I've held back from watering them and let nature do its thing, thinking it was mold needing to dry out. The other large one in a smaller pot has been doing great. Grateful for some advice.

It does sound as if over watering may be the issue with a fungal infection, or even root rot, being the end result. These plants are drought tolerant and require little watering, only when really dried out. Backing off on the watering is a good first step. If it's simply a fungus attacking the plant, you may be successful with fungicide. Root rot is a bit trickier, however.
