Everything it needs
9 essentials at a glance
Watering
Anthurium scherzerianum prefers to be kept consistently moist but not soggy.
Water when the top inch of soil feels dry, typically every 1-2 weeks. In the growing season (spring and summer), increase frequency to once a week. In 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, place it near a window with filtered sunlight for about 6-8 hours daily. Avoid direct sunlight, which can scorch the leaves. It can adapt to partial shade but may not bloom as profusely.
Soil
Anthurium prefers a well-draining potting mix, ideally composed of peat, perlite, and orchid bark.
The pH should be slightly acidic to neutral, around 5.5 to 7.0. Good drainage is essential to prevent root rot, so ensure the pot has drainage holes.
Humidity
This plant enjoys high humidity levels of 60% or more.
To increase humidity, consider using a humidifier, placing a pebble tray with water beneath the pot, or misting the leaves regularly. Signs of low humidity include browning leaf edges and wilting.
Temperature
Anthurium scherzerianum thrives in temperatures between 65-80°F (18-27°C).
It is sensitive to cold and should be protected from temperatures below 50°F (10°C). This plant is best suited for USDA hardiness zones 10-12.
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 once every 2-3 months in winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune as needed to remove dead or yellowing leaves, which helps maintain the plant's appearance and health.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can encourage new blooms. Pruning should be done in spring.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter. Carefully remove the plant, refresh the soil, and place it in the new pot.
Propagation
Propagation can be done through division or offsets.
The best time to propagate is during the growing season in spring. Carefully remove the plant from its pot, separate the offsets with roots, and replant them in their own pots with fresh potting mix. Water lightly after repotting.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and adjust watering habits. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Browning leaf tips
Why it happens
Typically due to low humidity or under-watering.
How to fix it
Increase humidity levels and ensure consistent watering to keep the soil moist.
Wilting leaves
Why it happens
Can be a sign of both over-watering and under-watering.
How to fix it
Assess soil moisture and adjust watering accordingly. Ensure proper drainage.
Root rot
Why it happens
Caused by over-watering and poor 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
Commonly attracted to stressed plants, particularly in low humidity.
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 begins to grow actively. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, maintain consistent moisture and humidity levels. Monitor for pests, as they can thrive in warm conditions.
Fall
In fall, gradually reduce watering as growth slows down. Continue to fertilize until late fall, then switch to a less frequent schedule.
Winter
In winter, reduce watering to every 2-3 weeks and keep the plant in a warm location away from drafts. Avoid fertilizing during this dormant period.
Toxicity & Safety
Anthurium scherzerianum 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 and gastrointestinal distress.
