Anthurium crystallinum, also known as the velvet cardboard anthurium, is a stunning tropical plant prized for its beautiful foliage. With proper care, these exotic houseplants can thrive indoors and add a touch of the tropics to any space. Here is a detailed guide on how to grow and care for Anthurium crystallinum.
Light Requirements
Anthurium crystallinum thrives in bright, indirect light. Place it near an east or west facing window where it will receive plenty of gentle sunlight. Direct southern exposure may scorch the leaves, while too little light will cause the foliage to lose its vibrant coloration.
Soil and Potting
Use a well-draining potting mix amended with perlite, orchid bark, or expanded clay pellets to provide airflow to the roots. Anthurium crystallinum prefers being slightly root-bound, so choose a pot that is only slightly larger than the root ball. Terracotta pots work well as they allow excess moisture to evaporate.
Watering and Humidity
Water thoroughly when the top inch of soil becomes dry, allowing excess water to drain freely from the drainage holes. Never allow the plant to sit in water. Maintain moderately high humidity around 60-80%. Grouping plants together, using a pebble tray, or misting the foliage daily can help boost humidity.
Temperature
Anthurium crystallinum thrives in temperatures between 60-85°F. Keep away from cold drafts and heating vents. Move to a cooler location during the summer months.
Fertilizer
Feed monthly during the growing season with a balanced liquid fertilizer diluted to half strength. Reduce feeding in the winter. Flush the soil periodically to prevent salt buildup.
Pruning and Shaping
Remove faded or damaged foliage and old flower spikes to maintain an attractive appearance. Cutting back leggy growth encourages bushier and more compact growth.
Propagation
Propagate new plants from seed or by dividing the plant when repotting. Take stem cuttings with at least two leaves. Place in water or moist potting mix until roots develop. New plants can be transplanted once a good root system is established.
Common Problems
Overwatering can lead to root rot. Allow soil to dry between waterings. Low humidity causes browning leaf tips. Increase humidity for the plant. Too much light causes scorched leaves. Move to a shadier spot. Mealybugs, aphids, and scale insects may infest the foliage. Wipe pests away with insecticidal soap or neem oil.
FAQs About Anthurium Crystallinum Care
How often should I water my Anthurium crystallinum?
Water thoroughly once the top inch of soil becomes dry. Allow excess moisture to drain away fully. Avoid allowing the plant to sit in waterlogged soil which can cause root rot.
What type of light does Anthurium crystallinum need?
These plants thrive in bright, filtered light. East or west facing windows are ideal locations. Direct southern sun will scorch the delicate foliage. If light levels are too low, the leaves lose their vibrant coloring.
What kind of potting mix is best for Anthurium crystallinum?
Use a well-draining potting soil amended with perlite, orchid bark or expanded clay pellets to provide airflow to the roots. Anthurium crystallinum prefers being somewhat root bound.
How humid should I keep my Anthurium crystallinum?
Maintain average household humidity between 60-80% relative humidity. Group plants together, use a pebble tray filled with water, or mist the plant daily to boost moisture levels around your Anthurium crystallinum.
Why are the leaf tips of my Anthurium crystallinum turning brown?
The most common cause of browning leaf tips is low humidity. Increase the humidity around your plant by misting the foliage daily or using a humidifier. Avoid cold drafts and heating vents which contribute to dry air.
How can I encourage my Anthurium crystallinum to bloom?
Proper care providing bright indirect light, warm temperatures, high humidity and monthly fertilization during growth periods will promote flowering. Reduce water and fertilizer during the winter months to induce blooming.
