Care
Cardinal Climber Vine Care
Plant in full sun in well-drained soil once temperatures are consistently warm. This heat-loving vine performs best during long summer days.
Provide sturdy support such as a trellis, arbor, or fence. The twining stems will naturally wrap around vertical structures as they grow.
Water regularly during establishment, then allow the top layer of soil to dry slightly between waterings. Avoid consistently soggy conditions.
Feed every 4–6 weeks during active growth with slow release fertilizer if desired.
Plants hardy in the ground may require winter protection when grown in containers in colder zones.
