One of my 15 gallon Dioon edule recently pushed a beautiful flush of sixteen leaves. A day after admiring its perfectly symmetrical crown of leaves, I noticed that the leaves were leaning slightly in one direction. Upon inspection, it appeared that the petiole / caudex connections were soft and unable to hold the leaves up firmly. I am assuming that I may have a root rot problem and the plant is unable to take up enough water to keep the leaves turgid in the heat of the day (95-100 degrees). The leaves appear normal in the early morning. Two days ago I applied a Subdue fungicide drench. Can you recommend anything else that I should be doing to prevent total plant failure? Should I consider removing leaves?
