One of four Lampranthus I have growing in my conservatory has died;
as far as I can see, the case was that its small roots have rotted
away, but there is no evidence of why (no signs of fungi, weevil or
anything). The others and layers from the same one in the same
conservatory border are fine.

The one difference is that it was smack bang under an Aloe ciliaris,
but others are well within the root zone of that.

Any ideas as to what might have happened?
