Why Trumpet Vine Fails to Bloom

Nitrogen and Shade: The Bloom Killers

A healthy, vigorous trumpet vine (Campsis) that doesn't bloom is likely getting too much nitrogen (from lawn fertilizer runoff) or too much shade.

Solutions

• Stop fertilizing the vine.
• Check for lawn fertilizer leaching into root zone.
• Ensure at least 6 hours of direct sun.
• Prune in late winter to encourage flowering wood.

Trumpet vines bloom readily when stressed slightly—lean conditions promote flowers over foliage.
