The plant you've asked about, Anthurium Portillae x RVDP, is a hybrid. "RVDP" is often used as an abbreviation for a specific hybrid cross: Anthurium Radicans x Villenaorum x Portillae (sometimes written as Portillae x (Radicans x Villenaorum) or similar variations).
Since it's a hybrid, its care is generally based on the requirements of its parent species, which are all jungle-dwelling Anthuriums. The best approach is to mimic the warm, humid, and brightly-lit conditions of a tropical understory.
Here is a comprehensive care guide based on the needs of its Anthurium Portillae x RVDP:
1. Light
Bright, Indirect Light is Best: Place your plant in a location where it receives bright, filtered light for about 6 hours a day, such as near an east-facing window or a few feet away from a south or west-facing window.
Avoid Direct Sun: Direct, hot sunlight will scorch the leaves, particularly the delicate, velvety foliage that some Anthurium hybrids inherit.
Can Tolerate Medium Light: While it can survive in medium light, growth will be slower and the leaves may not reach their full potential size or color.
2. Humidity
High Humidity is Crucial: Anthuriums thrive in high humidity, ideally 60% to 80% or higher. Low humidity is the most common cause of brown, crispy leaf edges.
How to Boost Humidity:
Use a humidifier near the plant (the most effective method).
Place the pot on a pebble tray filled with water (ensure the pot is not sitting directly in the water).
Group it with other plants to create a humid microclimate.
A bathroom or kitchen can be a good location if they receive enough light.
3. Watering
Keep Consistently Moist but Not Wet: Water thoroughly when the top 1 to 2 inches (2.5-5 cm) of the potting mix feels dry to the touch.
Avoid Overwatering: Ensure the pot has excellent drainage. Allowing the plant to sit in soggy soil is the fastest way to cause root rot, which is fatal.
Water Quality: Using filtered or rainwater can help prevent salt and mineral buildup, which can also cause brown leaf tips.
4. Soil/Potting Mix
Chunky and Well-Draining: Anthuriums are often epiphytic (grow on other trees) in nature, so their roots need a lot of air. Use a loose, chunky, and well-aerated potting mix.
Ideal Mix Components: A mix of orchid bark, coco coir or peat moss, perlite or pumice, and maybe some activated charcoal works well. The goal is a mix that holds some moisture but drains quickly and provides ample air circulation.
5. Temperature
Warm and Stable: The ideal temperature range is 65∘F to 85∘F (18∘C to 29∘C).
Avoid Cold Drafts: Keep the plant away from cold windows, A/C vents, and external doors, as sudden temperature drops can stress it. Temperatures below 60∘F (15∘C) can cause damage.
6. Fertilizing
Feed During Growing Season: Fertilize monthly or bi-weekly during the spring and summer (active growing period) with a balanced liquid fertilizer diluted to half or quarter strength.
Reduce/Stop in Winter: Cut back on feeding in the fall and winter when growth naturally slows down.
7. Other Tips Anthurium Portillae x RVDP
Pests: Inspect the leaves regularly for common houseplant pests like spider mites and thrips, especially in low-humidity environments.
Cleaning Leaves: Gently wipe the leaves with a soft, damp cloth to remove dust, which helps with photosynthesis. Avoid misting the velvety leaves directly, as water spots can damage the texture.
Repotting: Repot every 1-2 years or when the plant is root-bound, using a container that is only 1-2 inches larger in diameter.
