Everybody here had that same problem. I do not think fungus is the prime cause. With our four consecutive drought summers the plants went heat dormant every years just when the rhizomes put out new roots to store up energy for next years growth. As a result the rhizomes exhaust themselves totally using up all tissue, getting smaller and smaller and drying up completely. Fungus may have something to do later, but usually there is no plant tissue left to devour. Just crumbly, dry dirt where the rhizome and the roots used to be.

Remember that nice looking plant of H. 'Lime Tiara' that I had grown from a piece that Jim Hawes gave me? Well.....It wasn't looking good and went dormant early and I dug it up this fall and it had completely died. It was dry and crumbly and the crown turned to dust in my hands as I went through it looking for some living tissue. I would like to know what kind of fungal rot it died from.
