Antwort auf: Cypripedium acaule leaf disease (help needed) von Paul P. Perakos am 10 Juni, 2000 um 00:03:59:
I would assume that a fungus attacked the leaves of your plants. You may try to spray with a systemic fungicide (I don't know which fungicides are available in the US) and prevent the plants from further rain. The loss of leaves must not mean that the plants are bound to die, unless the rhizome stays healthy and produces a new (of course smaller) shoot bud for next year. Keep them dry for the rest of this growing period.
