Troubleshooting
Pink Trumpet Vine problems — and how to fix them
Pink Trumpet Vine (Podranea ricasoliana) 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.
Frost dieback
Foliage and young stems are damaged or killed by frost below -2°C (28°F). In borderline climates, plant against a sheltered south- or west-facing wall, and mulch roots heavily before winter.
Failure to bloom
Insufficient sun is the most common cause. Also check: excessive nitrogen fertilising (promotes leaves over flowers); drought stress during bud initiation; or the plant being too young (typically needs 2–3 seasons to bloom freely).
Aphids on new growth
Tender growing tips attract aphids in spring and early summer. Spray with a strong water jet or insecticidal soap. Encourage natural predators by avoiding broad-spectrum pesticides.
