Anthurium Care Guide
Light Requirements
-
Prefers bright, indirect light — too much direct sun = scorched leaves, too little = leggy growth and no blooms.
-
East or north-facing windows are ideal indoors.
-
Flowering Anthuriums need more light to keep blooming, while foliage types like clarinervium or crystallinum tolerate slightly lower light.
Watering
Anthuriums love moisture—but not too much:
-
Water when the top 1–2 inches of soil feel dry.
-
Keep evenly moist during the growing season, but let the soil dry a bit more in winter.
-
Avoid soggy roots—root rot is the enemy.
💡 Tip: Anthuriums prefer filtered or distilled water, especially if your tap water is hard or chlorinated.
Soil & Potting
Use a well-draining, chunky, and airy mix — these are epiphytic plants in the wild!
-
Ideal mix: Orchid bark + perlite + peat moss or coco coir.
-
Avoid heavy, dense potting soil.
Repot every 1–2 years or when roots outgrow the pot. Use pots with good drainage.
Temperature & Humidity
-
Thrives in 65–85°F (18–29°C) — keep away from drafts, AC vents, or cold windows.
-
Requires high humidity (60–80%) to thrive.
-
Use a humidifier or place the plant on a pebble tray.
-
Great for bathrooms or grouped with other tropicals.
-
Fertilizer
-
Feed every 4–6 weeks in spring and summer using a balanced, diluted liquid fertilizer or one formulated for blooming plants.
-
Don’t overfeed — they’re light feeders.
-
Cut back feeding in fall and winter.
Flowering Tips
Flowering Anthuriums (A. andraeanum) bloom best when:
-
They receive bright, indirect light
-
Humidity is consistently high
-
They’re slightly root-bound
-
Fed with a high-phosphorus fertilizer every 6 weeks
Each flower (technically a spathe and spadix) can last 6–8 weeks, with several blooms per year.
Pruning & Maintenance
-
Remove spent blooms and yellow or damaged leaves at the base with clean shears.
-
Wipe down leaves regularly to remove dust and help prevent pests.
Propagation
-
Best done by division of the rootball during repotting.
-
Foliage types can also be propagated from stem cuttings with nodes.
-
Place divisions or cuttings in moist, airy substrate and high humidity.
