Sudden rosette death

Occasionally and apparently healthy rosette on one or another of my houseleeks will suddenly turn yellow or orange and die very quickly, over just a few days.  Rosettes nearby are unaffected.  The affliction does not spread from a given point: the whole rosette suddenly capitulates.

Below is an example on Sempervivum ‘Sir William Lawrence’ with one rosette affected

I would be grateful if anyone can tell me what this condition is, though I somehow doubt there is any way of stopping it and it only affects single rosette a few times each year..

  1. I've experienced this! Probably one a year on average will all of a sudden go "crispy" and die. But as you say, the others around it will be fine.
