Heuchera brown patches

I've just noticed that the two heuchera plants planted against my back wall have brown papery patches. The heuchera plant up against my front wall is fine. Conditions would seem similar for all 3 plants, though the front is more shady.

I would be most grateful some help in identifying this condition....

 

Just coming back to add that I removed the 20 or so leaves that looked like this shortly after posting this query. The plants are now in fine health and there is no sign whatsoever of the problem re-occuring. Yaaaay!

 

The leaves will have that appearance if ......

a) the plants are in bright sunshine

b) when you've been watering the garden you've got water on the plants leaves - that should never happen. When you water your garden always water the soil and never foliage.

 

Thank you Louise - it's good to know what caused it!

 

HI Canna,

Louise has it spot on.

A simple trick is to avoid again, is to just water early in the morning. The leaves will dry out before any high sun builds up. This is also recommended as foliage that remains wet is much more likely to suffer from foliar diseases. :D
