The Philodendron sharoniae is a captivating plant that has become a popular choice for indoor plant enthusiasts due to its distinct appearance. This species originates from the tropical rainforests of Colombia and Ecuador, where it thrives in humid, shaded environments.
Characteristics of Philodendron Sharoniae
This striking aroid is recognized for its long, deeply lobed leaves that can reach substantial lengths, sometimes exceeding two to three feet when mature. The foliage typically displays a deep green color with a matte or slightly glossy texture. Young leaves may emerge with a unique salmon-pink color before transitioning to the mature deep green. The leaves also feature a corrugated or pleated surface with noticeable parallel veins.
Philodendron sharoniae exhibits a climbing, hemiepiphytic growth habit, naturally climbing on other plants in its native habitat. It can reach lengths of up to three meters when provided with adequate support. This plant develops long internodes and aerial roots that assist in its climbing. When allowed to climb, its leaves tend to become significantly larger.
Caring for Philodendron Sharoniae
Light Requirements
Philodendron sharoniae thrives in bright, indirect light, mimicking its natural habitat. Placing the plant near a window with filtered light, such as an east, west, or lightly shaded south-facing window, is ideal. Providing at least four hours of bright, indirect light daily is beneficial. Direct sunlight can scorch the foliage. While it can tolerate lower light, this may result in slower growth and less vibrant foliage.
Watering Needs
Maintaining consistent moisture in the potting mix is important for Philodendron sharoniae, but avoid waterlogging. Water when the top one to two inches of soil feels dry. Ensure the pot has drainage holes to prevent water accumulation and root rot. Allow all excess water to drain out. Adjust watering frequency based on the season, with less water needed during cooler months.
Soil Mix
A loose, well-drained soil rich in organic matter provides an optimal growing environment. The plant prefers a porous and well-aerated potting mix that drains readily. A suitable mix can include components like peat moss or coco coir, perlite, and orchid bark. Amending the soil with charcoal can also be beneficial. This airy substrate helps prevent root rot.
Temperature and Humidity
Philodendron sharoniae prefers warm indoor temperatures, ideally ranging between 18°C and 29°C (65-85°F). Avoid cold drafts and temperatures below 13°C (55°F). This plant thrives in high humidity, ideally between 60% and 80%. Low humidity can lead to brown leaf edges. To increase humidity, use a humidifier, group plants, or place the pot on a pebble tray. Misting the leaves regularly can also help.
Fertilizing
Philodendron sharoniae is a relatively heavy feeder during its active growing season from spring through fall. Fertilize every two to four weeks with a balanced liquid fertilizer, diluted to half strength. It is generally better to fertilize more frequently at half strength than to apply a single strong dose. Reduce or stop fertilization during the dormant winter months.
Propagating Philodendron Sharoniae
Propagating Philodendron sharoniae is commonly achieved through stem cuttings during the active growing season. Select a healthy stem with several leaves and at least one node. Make a clean cut just below a node. Remove lower leaves to expose the nodes, where new roots will emerge.
Cuttings can be rooted in water or soil. For water propagation, place the cutting in a glass of water, ensuring all nodes are submerged. Change the water every few days. Roots typically form within a few weeks; once they are at least an inch long, transplant into soil.
For soil propagation, fill a small pot with a well-draining, moist potting mix. Plant the cutting, ensuring nodes are buried. Keep the soil consistently moist but not soggy. Place the potted cutting in a warm, humid environment with bright, indirect light to encourage root development.
Common Problems and Solutions
Yellowing leaves are a common issue with Philodendron sharoniae. This often indicates improper soil moisture, typically overwatering and potential root rot. If the soil feels soggy, allow it to dry out more before the next watering. Conversely, yellowing can occur from underwatering, where the plant may appear limp or wilted; a thorough watering is needed in this case. Yellow leaves can also result from too much direct sunlight or insufficient light.
Browning leaf edges or tips often signal low humidity or inconsistent watering. Increasing humidity around the plant can help. Drooping leaves can stem from either overwatering or underwatering; check soil moisture levels.
Pests such as spider mites, mealybugs, aphids, and scale can infest Philodendron sharoniae. Spider mites may cause stippling on leaves and fine webbing. Mealybugs appear as small, cottony insects, while scale look like tiny brown bumps. Isolate infested plants and treat with insecticidal soap or neem oil. Regular inspection aids early detection.
