How to Grow and Care for Philodendron Barrosoanum

The Philodendron Barrosoanum is a plant native to the rainforests of South America that brings a touch of the tropics indoors. This species is sought after for its unique foliage, yet it remains a manageable specimen for those with some houseplant experience.

Identifying Philodendron Barrosoanum

The definitive feature of Philodendron barrosoanum is its foliage, which transforms as the plant matures. Juvenile leaves are simple and small, but they develop into a tri-lobed shape with age. Mature leaves feature a long central lobe flanked by two smaller, backward-pointing lobes, resembling “bunny ears.” These deep green leaves have a leathery, semi-glossy texture.

This plant is a natural climber, or epiphyte, that grows on other trees to reach for light. This climbing habit is important for its development, as the plant requires support to produce its large, mature leaves. Without a structure like a totem or trellis to ascend, it may retain its smaller, juvenile leaf form.

Essential Care Guide

Light

Philodendron barrosoanum thrives in bright, indirect sunlight, which mimics the dappled sun of a tropical forest canopy. Place it near an east-facing window for gentle morning sun, or several feet from a south or west-facing window. Direct sun exposure should be avoided as it can scorch the leaves.

Soil

This philodendron requires a chunky, airy, and well-draining medium for proper root aeration. A quality aroid mix can be created by combining ingredients like orchid bark, perlite, and peat moss. This mixture ensures water drains effectively, preventing the soil from becoming waterlogged, which can lead to root rot.

Water

Follow a “soak and dry” method by thoroughly watering the plant until water runs from the drainage holes. Allow the top few inches of the soil to dry out before the next watering. It is better for the soil to be slightly dry than consistently moist, as these plants are sensitive to overwatering. Drooping leaves can indicate either too much or not enough water, so checking the soil moisture is a reliable guide.

Temperature and Humidity

Originating from a tropical environment, this philodendron prefers warm and humid conditions. It does well in average household temperatures but will flourish with higher humidity levels. To increase ambient moisture, you can group it with other plants, place it on a pebble tray filled with water, or use a humidifier. Regular misting can also be beneficial, especially during drier months.

Fertilizer

To support growth during the spring and summer growing season, use a balanced liquid fertilizer. Fertilize every other month while the plant is actively growing, diluting the solution to half-strength to avoid root burn. Alternatively, a slow-release product can be applied a few times a year. Suspend feeding during the dormant fall and winter months.

Propagation Techniques

Propagate Philodendron barrosoanum using stem cuttings. Identify a healthy section of the vine and locate a node—the small bump on the stem where leaves and roots emerge. Using clean shears, make a cut just below a node, ensuring your cutting includes at least one leaf and the node itself.

You can root the cutting by placing it in a jar of water with the node submerged, or by planting it directly into a moist, well-draining potting medium. For either method, place the new cutting in bright, indirect light and maintain consistent moisture to encourage root development.

Common Issues and Solutions

Pests such as spider mites and mealybugs can affect houseplants. Regularly inspect the leaves, especially the undersides, to catch infestations early. If pests are found, they can be managed by wiping the leaves with a cloth dipped in rubbing alcohol or using an insecticidal soap.

Yellowing leaves are a frequent problem and a sign of overwatering. This occurs when the soil remains too wet, depriving the roots of oxygen. If you notice yellow leaves, check the soil moisture and adjust your watering schedule, allowing the soil to dry out more between waterings to prevent root rot.

If your plant appears “leggy,” with long, bare stems and small leaves, it is likely not receiving enough light. This stretched growth is the plant’s attempt to reach for a brighter light source. The solution is to move the plant to a location with more bright, indirect sunlight, which will encourage compact growth.
