Small's Beardtongue problems — and how to fix them
Small's Beardtongue (Penstemon smallii) 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.
Crown rot in wet winters
Poorly drained soil during winter dormancy is fatal. Plant on slopes or in raised beds; ensure the crown stays as dry as possible between autumn and early spring.
Powdery mildew
Common in humid southeastern summers. Improve airflow by spacing plants 45 cm (18 in) apart and avoid wetting foliage. Remove infected leaves promptly.
Short lifespan
Typically lives 3–5 years. Self-seeds modestly in suitable conditions. Collect and sow seed each year or take cuttings to ensure continuity in the garden.
