Everything it needs
9 essentials at a glance
Watering
Anthurium pedatoradiatum 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 as needed, while 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 leaf wilting and browning at the tips.
Light
This plant thrives in bright, indirect light but can tolerate some direct morning sun.
Ideal placement is near a window with filtered light, receiving about 6-8 hours of light daily. Avoid low-light conditions as this can lead to leggy growth and reduced flowering.
Soil
Anthurium pedatoradiatum prefers a well-draining potting mix, ideally with a composition of peat, pine bark, and perlite.
A pH range of 5.5 to 6.5 is optimal. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.
Humidity
This plant enjoys high humidity levels, ideally between 60-80%.
To increase humidity, consider using a humidifier, placing a tray of water with pebbles beneath the pot, or misting the leaves regularly. Signs of low humidity stress include browning leaf edges and leaf curling.
Temperature
Anthurium pedatoradiatum thrives in temperatures between 65-80°F (18-27°C).
It is best suited for USDA hardiness zones 10-12. Protect the plant from temperatures below 50°F (10°C) as it is sensitive to cold drafts and extreme heat.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or similar, diluted to half strength.
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, stunted growth, and poor flowering.
Pruning
Prune as needed to remove dead or yellowing leaves and to shape the plant.
Use clean, sharp scissors or pruning shears to avoid disease transmission. Deadheading is not necessary, but removing spent flowers can encourage new growth.
Repotting
Repot every 1-2 years or when the plant becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter than the current one. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix, ensuring the root ball is level with the soil surface.
Propagation
Propagation can be achieved through division or stem cuttings.
For division, carefully separate the plant at the roots during repotting, ensuring each division has roots and leaves. For stem cuttings, take a healthy stem with a node, place it in water or moist soil, and keep it warm and humid until roots develop. The best time for propagation is during the growing season in spring.
When it's unhappy

Care through the year
Spring
In spring, increase watering and fertilization as the plant enters its active growth phase. Check for pests and repot if necessary.
Summer
During summer, maintain consistent moisture and humidity levels. Provide bright, indirect light and monitor for signs of heat stress.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize every 6-8 weeks until late fall.
Winter
In winter, reduce watering to every 2-3 weeks and avoid fertilizing. Keep the plant in a warm location away from cold drafts.
Toxicity & Safety
Anthurium pedatoradiatum is toxic to pets 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 may include drooling, difficulty swallowing, and vomiting.
