Climbing anthuriums offer a unique visual appeal as houseplants, distinguishing themselves with a vining growth habit, adding a touch of the tropics. Unlike compact varieties, they naturally ascend, allowing them to develop larger leaves and a more mature form. With appropriate care and structural support, these plants can flourish, bringing vibrant foliage and characteristic blooms into a home setting.
Characteristics of Climbing Anthuriums
Climbing anthuriums are often epiphytic or hemiepiphytic, growing on other plants or structures rather than directly in soil. This adaptation allows them to access more sunlight in dense tropical environments. They develop aerial roots from their stems, which are crucial for physical attachment to supports and absorbing moisture and nutrients from the air. In a home setting, their presence indicates the plant’s natural instinct to climb and seek additional moisture.
Essential Care for Climbing Anthuriums
Providing the right environment is important for the health and growth of climbing anthuriums.
Light
These plants thrive in bright, indirect light, mimicking their native filtered sunlight. Too much direct sun can yellow leaves or cause brown tips, while inadequate light leads to poor growth.
Water
Consistent moisture is important, but overwatering causes root rot and yellowing leaves. Keep the soil slightly moist, allowing the top layer to dry out before watering again.
Humidity
High humidity, ideally between 50% and 80%, is beneficial for climbing anthuriums. Increase humidity by:
Misting the leaves regularly.
Placing the plant on a pebble tray filled with water.
Using a humidifier.
Potting Mix
The potting mix should be coarse, well-draining, and airy. A suitable mix often includes orchid bark, perlite, coco coir, or peat moss. Slightly acidic soil with a pH between 5.5 and 6.5 is preferred.
Fertilization
During spring and summer, fertilize every two to four weeks with a balanced, water-soluble fertilizer diluted to half strength. Reduce or stop fertilization during fall and winter.
Providing Support and Training
Climbing anthuriums benefit significantly from structural support to encourage their natural growth habit. Providing support helps them achieve their full potential. Without support, these plants may become leggy or their leaves might not develop to full size. Moss poles are a common and effective choice, as they provide a textured surface that aerial roots can cling to and absorb moisture from. Other options include trellises or stakes.
Training
To train a climbing anthurium, gently guide its stems towards the chosen support. Use soft plant ties or twine to initially secure stems, ensuring they are not tied too tightly. Misting the moss pole encourages aerial roots to attach. As the plant grows, adjust ties and prune any leaves or stems growing away from the support. This guidance helps the plant establish itself and promotes healthy vertical development.
Propagating Climbing Anthuriums
Propagating climbing anthuriums is typically done using stem cuttings, especially those with aerial roots already present. Select a healthy stem section that includes at least one node, which is where new roots and leaves will emerge. Cuttings with existing aerial roots tend to root more reliably. After taking the cutting, allow the cut end to callus over for a few hours to a day, which can help prevent rot.
The prepared cutting can be rooted in water or moist sphagnum moss:
When rooting in water, ensure only the node and aerial roots are submerged, changing the water every few days to maintain freshness.
If using sphagnum moss, keep the moss consistently damp but not waterlogged.
Once new roots have developed and are several inches long, the cutting can be transferred to a well-draining potting mix. This method allows for the creation of new plants and helps to manage the size and shape of the parent plant.
Troubleshooting Common Problems
Addressing common issues helps maintain the health of climbing anthuriums. Yellowing leaves indicate overwatering or insufficient light; check soil moisture and light exposure. Brown tips signal low humidity or underwatering. Increase humidity through misting or using a pebble tray.
Pest infestations, such as spider mites, mealybugs, thrips, and aphids, can occur. These pests feed on plant sap, leading to stunted growth, yellowing, or mottled leaves. Regular inspection and prompt action, such as wiping affected areas with insecticidal soap, manage these issues. A lack of vigorous growth suggests a need for more light, consistent fertilization during the growing season, or a review of the potting mix for aeration and nutrients.
