Everything it needs
9 essentials at a glance
Watering
Anthurium andraeanum prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf tips.
Light
This plant thrives in bright, indirect light but can tolerate lower light conditions.
Ideally, it should receive 6-8 hours of filtered light daily. Avoid direct sunlight, which can scorch the leaves. If placed in lower light, growth may slow down, and flowering may decrease.
Soil
Anthurium prefers a well-draining potting mix with a pH of 5.5 to 6.5.
A mix of peat, pine bark, and perlite or orchid bark is ideal. Ensure the pot has drainage holes to prevent water retention, which can lead to root rot.
Humidity
This plant thrives in high humidity levels of 60-80%.
To increase humidity, consider using a humidifier, placing the pot on a pebble tray filled with water, or misting the leaves regularly. Signs of low humidity stress include brown leaf edges and drooping leaves.
Temperature
Anthurium prefers temperatures between 65-80°F (18-27°C) and is sensitive to cold drafts.
It is best suited for USDA hardiness zones 10-12. Protect it from temperatures below 50°F (10°C) as it can suffer from cold damage.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or a specialized orchid fertilizer.
Fertilize every 4-6 weeks during the growing season and reduce to every 8-10 weeks in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune anthurium as needed to remove dead or yellowing leaves and spent flowers.
Use clean, sharp scissors or pruning shears to make cuts at the base of the stem. Regular deadheading encourages new blooms and maintains a tidy appearance.
Repotting
Repot anthurium every 1-2 years or when it becomes root-bound.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter than the current one, and gently loosen the roots before placing it in fresh soil.
Propagation
Anthurium can be propagated through division or by taking stem cuttings.
For division, carefully separate the plant into sections, ensuring each has roots and leaves, and replant in fresh soil. For stem cuttings, take a healthy stem with a node, allow it to callous for a few hours, and then plant it in moist soil. The best time to propagate is during the growing season in spring or early summer.
When it's unhappy

Root rot
Why it happens
Over-watering and poor soil drainage.
How to fix it
Remove the plant from the pot, trim away affected roots, and repot in fresh, well-draining soil.
Pests (e.g., spider mites, aphids)
Why it happens
Dry conditions and stress.
How to fix it
Inspect the plant regularly, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering frequency as the plant enters its growing season. Fertilize every 4-6 weeks to encourage new growth and blooms.
Summer
During summer, maintain consistent moisture and humidity. Ensure the plant receives bright, indirect light for optimal growth.
Fall
In fall, gradually reduce watering frequency as the plant's growth slows. Continue fertilizing every 6-8 weeks until late fall.
Winter
In winter, water less frequently, allowing the soil to dry out more between waterings. Keep the plant in a warm location away from drafts.
Toxicity & Safety
Anthurium is toxic to pets (cats and dogs) and humans if ingested. The plant contains calcium oxalate crystals, which can cause irritation, swelling, and pain in the mouth and throat. Symptoms of ingestion include difficulty swallowing, drooling, and vomiting.
