Iris 'Jane Phillips' problems — and how to fix them
Iris 'Jane Phillips' (Iris 'Jane Phillips') 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.
Bacterial soft rot
Buried or overwatered rhizomes turn slimy and foul-smelling. Plant with tops exposed in free-draining soil and cut away affected tissue promptly.
Iris leaf spot
Fungal brown spots on foliage in damp weather; remove infected leaves, improve airflow and clear debris in autumn to break the cycle.
Reduced flowering when crowded
Congested clumps bloom poorly; lift and divide every three to four years after flowering to restore vigour.
Iris borer
Caterpillars tunnel into rhizomes and open the door to rot, mainly in North America. Remove old foliage in autumn and destroy affected rhizomes.
