Re: Pulmonaria

This happens in my garden when the weather is particularly lousy one
way or another and about this time of year.  If it gets on my nerves,
I just cut the plants back to the ground, when they throw new leaves
that remain (generally) nice for the rest of the season.

Have always assumed the problem is fungal.  Does not seem to affect
the plants as far as their return and bloom in following years.

Same with my lamb's ears, who dislike damp, humid weather and
probably wouldn't get what I've always assumed to be some kind of
rust if they really had full sun and less humidity.

You can probably fight it with some kind of fungicide.  I don't
bother - too many plants and I fugure it's a rather losing battle as
assorted fungi spores are all around all the time, just waiting for
the proper conditions to do their thing.

I really think it's one of those opportunistic fungal problems that
is connected with weather and excess moisture.

Maybe someone knows more about this  and has a "cure"....
