Everything it needs
9 essentials at a glance
Watering
Anthurium amnicola prefers consistently moist soil but should not be waterlogged.
Water when the top inch of soil feels dry, typically every 1-2 weeks. In the growing season (spring and summer), increase frequency, while in fall and winter, reduce 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 low light conditions.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight, as it can scorch the leaves. If the leaves start to lose their vibrant color, it may be a sign that it needs more light.
Soil
Anthurium amnicola prefers a well-draining potting mix rich in organic matter.
A pH range of 5.5 to 6.5 is ideal. A recommended potting mix includes peat, perlite, and orchid bark to ensure proper drainage and aeration.
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 drooping leaves.
Temperature
Anthurium amnicola thrives in temperatures between 65-80°F (18-27°C).
It is best suited for USDA hardiness zones 10-11. Protect it from temperatures below 50°F (10°C), as cold drafts can cause stress and damage.
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 and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune anthuriums to remove dead or yellowing leaves and to promote bushier growth.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can also encourage new blooms. Pruning is best done in spring.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes or water not absorbing properly. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Propagation can be done through division or stem cuttings.
For division, carefully separate the root ball into sections, ensuring each has roots and leaves. For stem cuttings, take a 4-6 inch cutting with a node, place it in water or moist soil, and keep it warm and humid until roots develop. The best time to propagate is in spring.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.

Low humidity and stress.
How to fix it
Increase humidity, regularly inspect for pests, and treat with insecticidal soap if necessary.
Wilting leaves
Why it happens
Under-watering or extreme temperature changes.
How to fix it
Check soil moisture and adjust watering, while also ensuring stable temperature conditions.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to promote new growth.
Summer
During summer, maintain consistent moisture and ensure the plant receives bright, indirect light. Monitor humidity levels closely.
Fall
In fall, gradually reduce watering frequency as the plant's growth slows. Continue fertilizing 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.
