Troubleshooting
Straw Foxglove problems — and how to fix them
Straw Foxglove (Digitalis lutea) 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.
Subtle, easily overlooked flowers
Its small, pale blooms can read as understated rather than showy. Plant in groups against darker foliage so the slender spires register in the border.
Crown rot in winter wet
Soggy soil rots the crown over winter. Provide sharp drainage, avoid heavy clay and keep mulch off the immediate crown.
Leaf spot in damp shade
Fungal spotting on foliage in still, humid, crowded plantings. Improve spacing and airflow and clear away affected leaves.
Aphids on spikes
Sap-feeders can cluster on flower stems and distort blooms. Hose them off or rely on predators for light infestations.
