How to Care for Anthurium Clarinervium
Anthurium Clarinervium Soil Requirements
Anthurium clarinervium plants have epiphyte traits. They thrive in well-draining soil that never gets soggy after watering. The plant roots prefer a constant oxygen supply for successful growth.
A damp environment will increase the risk of root rot. Managing and treating root rot among aroid plants can be a daunting experience.
Use a pre-made soil orchid mix with organic matter and water retention materials. It will create an environment for anthurium clarinervium to thrive well.
Ensure the potting medium has a pH range of 5.5 to 6.5. The slightly acidic medium is safe for growing this aroid plant. Add peat or bark to mimic the natural ecosystem of epiphytes.
Another option is to combine coconut coir, perlite, pumice, orchid bark, compost, gravel, coarse sand, and crushed lava rock with long-fiber sphagnum moss to make a quality potting media.
Anthurium Clarinervium Watering Needs
Anthurium clarinervium thrives in slightly moist soil. Excess soil moisture will facilitate root rot and other fungal diseases to the plant.
Always water the houseplant when 2-3 inches of topsoil is dry. Soak the potting mix until excess water drains through the drainage holes.
I recommend watering the plant once a week during spring and summer. Reduce the watering frequency during late fall and winter.
Use distilled or rainwater to soak the potting soil. Tap water contains minerals that increase soil toxicity around the root system. Allow the tap water to sit overnight before watering your plant.
Anthurium Clarinervium Light Requirement
Anthurium clarinervium thrives in bright indirect sunlight. The aroid plant can also tolerate low light conditions though it might develop leggy stems.
Direct sunlight exposure will scorch the leaves. Replicate the plant’s natural habitat when growing it at home. Put the aroid plant in a spot receiving bright indirect sunlight.
Anthurium clarinervium can experience slow growth in winter. Be sure to provide less light until the dormancy stage is over. Use artificial lights in dark indoor spaces.
Early morning or late evening direct sunlight is harmless to this aroid plant. It can endure 4-5 hours of low-intensity natural light.
Humidity Requirement for Anthurium Clarinervium
High humidity is a crucial element of anthurium clarinervium care, and it thrives in a steamy-tropical jungle of Southern Mexico. Rock-dwellers can tolerate low humidity.
Maintain at least 50% indoor humidity level for this aroid plant to flourish and stay happy. Ensure the indoor environment mimic its natural setting.
Group the plant with other houseplants to help raise the humidity level. Another excellent option is to use an electric humidifier to increase the indoor humidity level.
Low humidity is the leading cause of anthurium leaves curling problem. Besides that, it results in anthurium clarinervium brown leaf tips.
High humidity with poor indoor ventilation will encourage fungal pathogens to thrive. These pathogens will ruin the stunning appearance of the foliages and the entire plant.
Anthurium Clarinervium Temperature Range
Anthurium clarinervium thrives in a warm and humid environment. Maintain an indoor temperature range between 68oF (22oC) and 80oF (27oC).
Any temperature below 55oF (13oC) will trigger dormancy and even kill the plant. High temperatures will cause leaves to curl and droop.
Avoid extreme and sudden temperature fluctuations by all means. Besides that, keep your anthurium plant away from cold and hot drafts.
How to Fertilize Anthurium Clarinervium
Anthurium clarinervium can thrive between rocks without fertilizer nutrients. Besides that, most aroid plants are light feeders when compared to other tropical plants.
Feed your indoor plant every 4-6 weeks during spring and summer. Use a water-soluble and balanced fertilizer to feed your anthurium clarinervium plant.
Do not apply fertilizer to this aroid plant during winter. It is the period where the plant experiences dormancy and does not utilize fertilizer nutrients.
Remember to flush the potting medium every three months to avoid salt buildup. Excess salt accumulation will burn the root systems.
I recommend the use of organic fertilizers for houseplants rather than artificial counterparts. It would be best to read my guide on How to Make Homemade Fertilizer for Houseplants.
Anthurium Clarinervium Flower
Most anthurium cultivars produce stunning flowers. But anthurium clarinervium produces spadix with small seasonal blooms that are pale green with variable violate hues.
These flowers develop a cluster of berries after pollination. The berries can last long and take time to mature. I recommend snipping the flowers to conserve energy and beauty.
How to Prune Anthurium Clarinervium
Anthurium clarinervium requires minimal pruning requirements. It helps to groom the houseplant and remove old or damaged leaves.
Old leaves removal also helps to conserve energy for the new growths. Besides that, it prevents infections from spreading to other plant parts.
Use a sharp and sterilized hand pruner to cut off the old or infected leaves. I recommend pruning this aroid plant during springtime only.
How to Re-pot Anthurium Clarinervium
Re-potting isn’t a crucial anthurium clarinervium care. This aroid plant experiences a slow growth rate and the roots tend to fill the container after 2-3 years.
Re-pot the plant every 2-3 years due to root-bound issues. Anthurium clarinervium leaves turning yellow and stunted growth are indicators of a root-bound problem.
Remove the plant from the pot with utmost care. Use fresh orchid mix and a container slightly bigger than the previous one. Place the plant in the pot and fill it with the orchid soil.
Soak the potting mix and place the plant in a dim environment. Do not fertilize the plant until new growths appear. Be patient and provide ultimate anthurium clarinervium care.
Anthurium Clarinervium Propagation
Seeds, division, and stem cuttings are the basic methods for your anthurium clarinervium propagation. The division is the easiest method and stem cuttings can be a little bit tricky.
Stem cuttings and division methods are best during springtime. You can also buy seeds from a reputable plant store to grow new plants.

Pests
Anthurium clarivervium plants are less vulnerable to pest infestations. But high humidity and excess soil moisture will invite aphids and mealybugs.
Reduce the watering frequency and apply insecticidal soap spray to eliminate the pests. Besides that, improve air circulation around the plant to combat insect infestation.
Diseases
Overwatering, high humidity, and poor ventilation are the possible cause of diseases on this aroid plant. Root rot is the leading disease caused by overwatering.
Reduce the watering frequency after re-potting the plant. Use a copper fungicide to treat the aroid plant from the fungal pathogen growth.
Anthurium Clarinervium Leaves Curling
Underwatering, overwatering, low humidity, and drafts are the main cause of anthurium clarinervium leaves curling. Investigate your plant to identify the exact cause before fixing it.
