Iris reticulata 'Harmony' problems — and how to fix them
Iris reticulata 'Harmony' (Iris reticulata 'Harmony') 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.
Summer wet and bulb rot
Moisture during dormancy rots bulbs and shortens the planting's life. Use sharply drained soil, or lift and store dry, or grow in pots kept dry in summer.
Ink-spot disease
A fungal disease causing black blotches on bulbs and leaves; destroy infected bulbs and avoid replanting reticulata irises in the same ground.
Bulb splitting into grassy non-flowering offsets
Bulbs often divide into many small bulblets that only make leaves; feed potassium after flowering and grow lean to keep flowering-size bulbs.
Slug and snail grazing
Early flowers and emerging shoots are eaten by slugs and snails in mild damp spells; protect buds as they appear.
