My personal favorite indoor plant: Anthurium! How to Keep Your Indoor Anthurium Healthy and Blooming
With a little attention to light, humidity, and watering, anthuriums are rewarding, long-blooming houseplants that add color and texture to your home. They are simply gorgeous and, in my opinion, one of the easiest tropical plants to maintain indoors with a plethora of options when it comes to spathe (flower) color varieties. Start with a bright spot, a well-draining mix, and a gentle watering routine—and enjoy watching those glossy leaves and striking spathes flourish.
Anthuriums are beloved for their glossy, heart-shaped leaves and long-lasting, colorful spathes (often called flowers). With the right light, humidity, and routine, these tropical beauties make stunning, low-maintenance houseplants that reward you with months of blooms. This guide covers everything a beginner needs to know to keep anthuriums thriving indoors.
Quick overview
Light: Bright, indirect light; avoid direct sun.
Water: Evenly moist but never waterlogged; allow top 1–2 inches of soil to dry between waterings.
Humidity: Prefers 60%+ but tolerant of average home humidity with support.
Temperature: 65–80°F (18–27°C); keep above 60°F if possible.
Soil & potting: Fast-draining, airy mix (peat + perlite or orchid bark).
Fertilizer: Balanced, diluted houseplant fertilizer during growing season.
Choosing the right spot:
Place your anthurium in bright, indirect light—near an east- or north-facing window or a few feet back from a south- or west-facing window. Direct midday sun can scorch the leaves; too little light reduces flowering and causes leggy growth. Rotate the plant every few weeks so it grows evenly.
Watering routine:
Anthuriums like consistent moisture but hate sitting in soggy soil.
Check the soil: Stick your finger 1–2 inches into the potting mix. Water when the top 1–2 inches feel dry.
Watering method: Water thoroughly until it runs out the drainage holes, then allow excess to drain. Empty any saucers after 15–30 minutes.
Avoid overwatering signs: Yellowing lower leaves, mushy stems, or a sour smell from the soil.
Underwatering signs: Brown, crispy leaf edges and drooping leaves.
Humidity and misting - Because anthuriums are tropical, they appreciate higher humidity.
Target humidity: 50–70% for healthiest foliage and best flowering.
Boost humidity: Use a humidifier, group plants together, or place the pot on a tray of pebbles with water (ensure the pot base is above the water).
Misting: Light misting can help but isn’t a substitute for steady humidity; avoid heavy misting that keeps leaves wet for long periods.
Soil and repotting - A well-draining, airy mix prevents root rot and encourages healthy growth.
Recommended mix: 40% peat or coco coir + 30% perlite + 30% orchid bark (or use aroid/epiphytic mixes).
Pot choice: A pot with drainage holes to minimize roots becoming stagnant in soggy soil which can lead to root-rot. Terracotta pots help wick excess moisture; plastic retains moisture longer.
Repotting: Every 2–3 years or when roots fill the pot. Repot in spring, using fresh mix and only one pot size up.
Fertilizing (Optional but recommended) - Feed during the active growing season (spring through early fall).
Frequency: Every 4–6 weeks.
Type: Balanced, water-soluble houseplant fertilizer (e.g., 10-10-10) at half strength, or use a fertilizer formulated for blooming houseplants.
Caution: Too much fertilizer can burn roots or cause foliar issues—lean toward underfeeding rather than overfeeding.
Light and temperature tips for more blooms:
Increase indirect light slightly during bloom season to encourage more spathes.
Maintain steady temperatures between 65–80°F (18–27°C); avoid cold drafts and sudden drops below 60°F.
Night temperature: A small day–night temperature drop (a few degrees) can encourage flowering for some varieties.
Pruning, cleaning, and pest care
Pruning: Remove spent spathes and yellowing leaves at the base to keep the plant tidy and direct energy to new growth.
Cleaning: Wipe leaves occasionally with a damp cloth to remove dust and help photosynthesis.
Pests: Watch for mealybugs, spider mites, scale, and aphids. Treat small infestations with neem oil, insecticidal soap, or by wiping pests off with alcohol-dampened cotton swabs. Quarantine new plants for 2–4 weeks.
Common problems and fixes
Brown leaf tips: Low humidity, fluoride/salt buildup, or inconsistent watering. Flush the soil occasionally, increase humidity, and use filtered water if needed.
Yellowing lower leaves: Natural aging or overwatering—check roots and adjust watering.
No blooms: Likely not enough light, low humidity, or insufficient feeding. Try brighter indirect light, a humidity boost, and regular fertilization in spring/summer.
Soft, mushy roots/stem: Root rot from waterlogged soil—repot into fresh, fast-draining mix, trim affected roots, and reduce watering.
Propagation (if desired)- Anthuriums are usually propagated by division or stem cuttings.
Division: Best when repotting; gently separate clumps ensuring each division has roots and a few leaves.
Stem cuttings: Take a healthy stem with at least one node, place in water or moist mix until roots form, then pot up.
Popular anthurium varieties to try
Anthurium andraeanum (flamingo lily): Classic glossy spathes in red, pink, white.
Anthurium scherzerianum: Curled orange-red spathes and a distinctive spadix.
Anthurium clarinervium: Valved heart-shaped leaves with striking veins—grown primarily for foliage.
Anthurium crystallinum: Velvet leaves with bold veins—another foliage favorite.
