Everything it needs
9 essentials at a glance
Watering
Anthurium regale prefers to be kept consistently moist but not soggy.
Water when the top inch of soil feels dry, typically every 1-2 weeks, adjusting frequency based on humidity and temperature. In the growing season (spring and summer), increase watering, while in fall and winter, reduce it. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf tips.
Light
Anthurium regale thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight, as it can scorch the leaves. If the plant is not getting enough light, it may exhibit slow growth and leggy stems.
Soil
This plant prefers a well-draining potting mix rich in organic matter.
A mix of peat, pine bark, and perlite works well, with a pH range of 5.5 to 6.5. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.
Humidity
Anthurium regale enjoys high humidity levels, ideally between 60-80%.
To increase humidity, consider using a humidifier, placing a tray of water near the plant, or misting the leaves regularly. Signs of low humidity stress include browning leaf edges and wilting.
Temperature
The ideal temperature range for Anthurium regale is 65-80°F (18-27°C).
It is sensitive to cold and should be kept away from drafts and 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, diluted to half strength.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Anthurium regale to remove dead or damaged leaves and to encourage bushier growth.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but removing spent flowers can help maintain the plant's appearance. Prune in spring for best results.
Repotting
Repot Anthurium regale every 1-2 years or when it becomes root-bound.
Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Choose a pot that is 1-2 inches larger in diameter than the current one. Carefully remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Anthurium regale can be propagated through division or stem cuttings.
For division, carefully separate the plant into sections during repotting, ensuring each section has roots. For stem cuttings, take a healthy stem with a few leaves, dip the cut end in rooting hormone, and place it in moist potting mix. Best timing for propagation is in spring or early summer.

Summer
During summer, maintain consistent moisture and humidity levels. Ensure the plant receives adequate light while protecting it from direct sun.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to monitor humidity and light levels, and prepare for potential repotting if necessary.
Winter
In winter, reduce watering frequency and stop fertilizing. Keep the plant in a warm location, away from drafts, and maintain humidity levels.
