The Philodendron Splendid, a hybrid of Philodendron verrucosum and Philodendron melanochrysum, is known for its striking foliage. This article explains what defines a mature Philodendron Splendid and how to cultivate its impressive form.
What Defines a Mature Philodendron Splendid
A mature Philodendron Splendid shows a significant increase in leaf size, often exceeding 12 inches, with some reaching up to 2 feet. Leaves transition from a heart-shaped juvenile form to an elongated, sometimes deeply lobed shape.
Mature leaves feature a velvety, dark green surface with prominent, lighter veins. The plant’s growth habit shifts from bushy to climbing, supported by robust aerial roots. Stems also become thicker to support the larger foliage.
Cultivating Maturity in Your Philodendron Splendid
To encourage maturity, provide a sturdy moss pole or other climbing support. This mimics its natural climbing habit, signaling the plant to produce larger leaves. Keeping the moss pole moist helps aerial roots establish and supports robust growth.
Optimal lighting is crucial for promoting maturity. Philodendron Splendid thrives in bright, indirect light, like that from an east or northeast-facing window. Insufficient light hinders maturation, resulting in smaller leaves and leggy growth.
Consistent high humidity, ideally between 60% and 80%, is important for healthy aerial root development and vigorous growth. While it can survive in average household humidity, elevated levels encourage more expansive growth and maturity.
Consistent fertilization during the growing season fuels larger leaf production. Apply a diluted, balanced water-soluble fertilizer monthly during spring and summer. Stable temperatures (65-80°F) also support continuous growth towards maturity.
Ongoing Care for a Mature Philodendron Splendid
Care requirements adapt once the Philodendron Splendid matures. Larger plants may need more frequent watering. Allow the top 50% of soil to dry between waterings to prevent root rot. Water thoroughly, letting excess drain from the pot.
Consistent fertilization sustains large leaves and continued growth. Fertilize monthly during spring and summer with a diluted houseplant fertilizer. Pruning helps maintain shape and size, directing energy towards producing more substantial foliage.
Repotting is needed as the plant grows, typically every one to two years, or when roots emerge from drainage holes. When repotting, select a new pot only 2 to 4 inches larger in diameter to prevent overwatering. Mature plants can tolerate being somewhat root-bound for longer periods than juveniles, but eventually require more space.
The continued presence of a strong support system remains important. The plant will continue to climb and produce larger leaves if adequately supported.
Troubleshooting Maturity Challenges
Issues can impede a Philodendron Splendid’s maturity or cause regression. Small leaves often indicate insufficient light, inadequate climbing support, humidity, or nutrients. Bright, indirect light and a moss pole are needed for larger leaves to develop.
Leggy growth, characterized by elongated stems with widely spaced, smaller leaves, results from insufficient light. The plant stretches in search of more light, hindering mature foliage development. Relocating the plant to a brighter spot or supplementing with grow lights can resolve this.
Loss of the characteristic velvety texture or rich dark green color can signify poor light, nutrient deficiencies, or pest stress. Ensuring consistent optimal light and a regular fertilization schedule can help restore leaf health.
If aerial roots do not attach to support, it is often due to low humidity or a dry support. Increasing ambient humidity (60-80%) and keeping the moss pole moist encourages aerial roots to cling, facilitating upward climb and maturation.
