Philodendron Subincisum is a popular houseplant known for its attractive foliage and ease of care. This article will provide you with everything you need to know about growing and caring for this plant.


Philodendron Subincisum, also known as the “Silver Sword Philodendron,” is a native of the tropical rainforests of Central and South America. It is a member of the Araceae family, which includes other popular houseplants such as Monstera, ZZ plants, and Peace Lilies. This plant has become increasingly popular due to its unique, silvery-green foliage and easy-to-care-for nature.

Appearance and Characteristics

Philodendron Subincisum is a compact, clumping plant that grows up to two feet tall and three feet wide. Its leaves are large, arrow-shaped, and have a striking silvery-green color with prominent veins. The plant’s stems are also a silvery-green color and are covered in small, fine hairs.

Light Requirements

Philodendron Subincisum prefers bright, indirect light. Direct sunlight can scorch its leaves, while low light can cause the plant to become leggy and lose its vibrant color. The plant can tolerate some shade, but it should not be placed in a completely dark area.


The plant should be watered once a week during the growing season and once every two weeks during the winter months. It is important not to overwater the plant as this can lead to root rot. Allow the top inch of soil to dry out before watering again. It is also important to avoid getting water on the leaves as this can cause leaf spots.

Temperature and Humidity

Philodendron Subincisum prefers warm temperatures between 65-80°F. It is important to keep the plant away from cold drafts as this can cause the leaves to yellow and drop. The plant also prefers high humidity, so it is recommended to mist it regularly or place a humidifier nearby.

The plant prefers well-draining soil that is rich in organic matter. A mix of peat moss, perlite, and vermiculite is ideal for this plant. It is also important to ensure that the pot has good drainage to prevent water from pooling in the soil.


Philodendron Subincisum benefits from regular fertilization during the growing season. A balanced, water-soluble fertilizer should be used every two weeks. It is important not to over-fertilize the plant as this can cause leaf burn and damage the roots.


Philodendron Subincisum can be propagated through stem cuttings. Simply take a cutting from the stem and place it in water or moist soil. It is important to ensure that the cutting has at least one node, which is where new roots will form. Once the roots have formed, the cutting can be transplanted into a pot with soil.

Pests and Diseases

The plant is relatively pest and disease-free, but it can be susceptible to spider mites, mealybugs, and scale insects. It is important to inspect the plant regularly for signs of infestation and treat it immediately with an appropriate insecticide.
