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.
