Caring for Anthurium Plants Indoors

Raise the Humidity

Anthurium plants thrive in high humidity, which can be challenging to maintain indoors. However, newer cultivars are less demanding than their predecessors. To increase humidity levels, use a humidity tray or room humidifier when the relative humidity drops below 50%. Grouping plants together can also help retain moisture. Keep an eye out for brown leaf tips, as they may indicate dry air.

To Repot…or Not

Spring is the best time to repot your Anthurium plant when new growth emerges. Choose a pot that is only slightly larger, about 1-2 inches (2.5-5 cm) bigger, and ensure it has drainage holes. Set the plant high in the pot so that the crown sits above the soil line. If roots start appearing at the surface between repottings, cover them with potting mix. Proper drainage is crucial to prevent soggy soil, which can harm the plant.

Keep it Clean

Anthurium leaves naturally have a glossy appearance. To maintain their shine, gently wipe them with a damp cloth to remove dust. Avoid dripping water directly on the leaves, as it may cause brown spots that require treatment with a fungicide.

Troubleshooting Yellow Leaves and Pests

Yellow leaves are often a sign of over-watering or exposure to cold drafts. Anthurium plants thrive in warmth year-round, so ensure they are kept away from cold blasts. If you notice webbing between the leaves and stems, it may indicate a spider mite infestation. Treat any infestation promptly. Fungus gnats, attracted to wet potting mixes, can also be dealt with easily.

Anthurium Plant Care Tips

Here are some essential tips to keep in mind when caring for your Anthurium plant:

  • Origin: Anthurium plants are native to Colombia.
  • Height: They can reach up to 18 inches (45 cm) in height, but compact cultivars stay around 12 inches (30 cm). Taller plants may require staking.
  • Light: Anthurium plants thrive in bright, indirect light. Aim for at least 4 hours of sunlight daily, but avoid direct sun exposure that can cause leaf browning. A sunny window filtered by a curtain is ideal.
  • Water: Keep the soil evenly moist during spring and summer, and slightly drier in winter. Over-watering can lead to yellow leaves, so ensure proper drainage by using pots with drainage holes.
  • Humidity: Anthurium plants crave high humidity. Aim for a relative humidity of 50% or higher. Avoid using a plant mister, as droplets of water can cause leaf blight. Consider using a cool-mist room humidifier to increase humidity.
  • Temperature: Anthurium plants prefer temperatures between 65-80°F (18-27°C). Protect them from cold drafts caused by doorways, windows, and air conditioning vents.
  • Soil: Use a peat moss-based potting mix with added perlite for good drainage. African violet potting mix is also suitable.
  • Fertilizer: Feed your Anthurium plant every 2 weeks during spring and summer with a high-phosphorus water-soluble fertilizer.
  • Propagation: Divide crowded clumps when repotting. Gently pull away a new crown near the main plant and plant it separately in a small container, ensuring the crown remains above the soil line. Your new plant should bloom in about a year.
