How to overwinter anthurium clarinervium (velvet cardboard anthurium)

No hardiness zone is recorded for anthurium clarinervium (velvet cardboard anthurium); it prefers to stay above about 18°C (64°F) while in growth, so treat it as frost-tender unless you know otherwise for your area. Anthurium clarinervium (Velvet Cardboard Anthurium) is frost-tender, so overwintering means bringing it inside and letting it rest rather than pushing it to grow. Move it indoors well before the first frost, give it the brightest spot you have (light levels indoors drop sharply in winter), and keep it away from both cold window glass and hot radiators — the swing between the two does more damage than the cold itself.

Bring indoors when nights start dropping below about 10°C, ahead of the first frost.

Cut watering right back — anthurium clarinervium (velvet cardboard anthurium) uses far less while growth slows, and cold, wet compost is the usual cause of winter root rot. Stop feeding until spring.

Watering on the same schedule as summer. In winter that keeps the roots sodden while the plant is barely drinking, and anthurium clarinervium (velvet cardboard anthurium) rots from the base.
