Name: Cindy Vasko VA (Zone 6b) Restless with wanderlust.
New growth, and we've had overnight temps low enough for frosts plus high winds and lots of rain in the last week or two. New to iris and I don't know what frost damage and nutritional deficiencies (or abundances) look like yet...thank you
Give me land, lots of land, under starry skies above. Don't fence me in.
Frost damage is usually black or brown/translucent. Nutrient deficiencies are difficult to determine by eye since many share the same symptoms. Could be virus too. Impossible to tell, but I wouldn't say frost no.
