Frequently Asked Questions
Mandevilla climbs by twining — guide the new growth around trellis wires or lattice and it will anchor itself. Prune in early spring to control size and encourage dense flowering. In SWFL, it grows vigorously from April through October.
Mandevilla is frost-sensitive and will die back after temperatures drop below 35°F. In Zone 10a coastal Naples, frosts are rare and Mandevilla often survives as a near-perennial. In Alva (Zone 9b), protect with frost cloth during cold nights or treat as an annual with replacement in spring.
