Tube Beardtongue problems — and how to fix them
Tube Beardtongue (Penstemon tubaeflorus) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot in wet soils
The single most common failure: planting in heavy, waterlogged, or poorly drained soil causes rapid root and crown rot, especially in winter — excellent drainage is essential and the plant should never sit in standing water.
Stem lodging
In fertile or moist soils the stems become tall and lax, flopping over in wind or rain; grow in lean, dry conditions without staking — the naturally upright habit is maintained only in open, well-drained sites.
