Also called flamingo flowers for their unique, bright red, green, and white colors, they can bloom repeatedly for long periods. Blooming varieties are distinctive with heart-shaped waxy spathes (i.e., modified leaf around the flower) and red or yellow spikes. Many anthuriums are climbers, and all need high humidity and warmth to thrive
Growing Conditions:
Light
-
Anthuriums prefer sun over shade but too much direct light can scorch the leaves. Inadequate light causes poor growth and few flowers. The ideal location for your plant provides six hours of bright, indirect sunlight daily.
Soil
-
Anthuriums grow similarly to orchids, so potting material needs to be coarse and drain well to provide adequate air circulation around the roots. Mosses, cocoa coir, or a 50-50 combination of orchid and houseplant potting medium make a good mix. You can also add sand and peat moss to orchid mix for a coarse well-draining soil.
Water
-
Keep soil slightly moist and never allow it to dry out completely.
-
Water indoor plants about once a week or when the top of the soil is dry to the touch.
-
Grown outdoors plants may need water every two to three days. Water your plant until it runs from the pot's drainage holes but do not leave it to sit in water. Anthuriums are vulnerable to root rot.
Fertilizer
-
Feed a high phosphorus liquid fertilizer throughout the growing period. Dilute to 1/4 strength and feed every week. Phosphorus-rich fertilizer encourages your anthurium to flower.
Temperature and Humidity
-
All species are native to the tropics, and prefer high humidity and temperatures between 65°F and 85°F. They'll be damaged in temperatures below 60°F, and die off when temperatures dip to 40°F.
In dry climates or during dry winter months, set it on a pebble tray to keep humidity levels high. You may find it necessary to run a humidifier constantly during dry months.
