Troubleshooting
Iris 'Black Gamecock' problems — and how to fix them
Iris 'Black Gamecock' (Iris louisiana 'Black Gamecock') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drying out
Unlike bearded irises it suffers if soil dries, with stunted growth and poor bloom. Keep it permanently moist or at the pond edge.
Iron chlorosis
Alkaline soil or hard water yellows the foliage between veins. Use acidic feeds, ericaceous compost and avoid lime to keep leaves green.
Aggressive spread
In ideal wet conditions it colonises quickly; lift and divide or contain it to stop it crowding neighbours.
Reduced flowering in shade or when congested
Too little sun or overcrowded clumps cut bloom; site in full sun and divide every few years after flowering.
