Everything it needs
9 essentials at a glance
Watering
Philodendron erubescens prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf droop and crisp edges.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Ideally, place it near a window where it receives filtered sunlight for about 6-8 hours a day. Avoid direct sunlight as it can scorch the leaves, but it can adapt to partial shade.
Soil
Philodendron erubescens prefers a well-draining potting mix with a pH range of 5.5 to 7.0.
A mix of peat moss, perlite, and orchid bark is ideal for ensuring good drainage and aeration. Avoid heavy soils that retain too much moisture.
Humidity
This plant enjoys high humidity levels of 60% or more.
To increase humidity, consider using a humidifier, placing a pebble tray with water under the pot, or misting the leaves regularly. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Philodendron erubescens thrives in temperatures between 65-80°F (18-27°C).
It is not frost-tolerant and should be kept away from cold drafts. The plant can tolerate temperatures as low as 50°F (10°C) but should be protected from extreme heat above 90°F (32°C).
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 during the growing season, every 4-6 weeks.
In fall and winter, reduce fertilization to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor leaf development.
Pruning
Prune Philodendron erubescens in spring to remove any dead or yellowing leaves and to shape the plant.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but you can trim back leggy growth to encourage bushier growth.
Repotting
Repot every 1-2 years or when the roots outgrow the pot.
Signs that it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter, and gently loosen the roots before placing it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or division.
For stem cuttings, take a cutting with at least one leaf and a node, place it in water or moist soil, and keep it warm and humid until roots develop, usually within 2-4 weeks. Division can be done during repotting, ensuring each division has roots and at least one leaf.

Care through the year
Spring
In spring, increase watering as the plant begins to actively grow. Consider fertilizing every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives bright, indirect light and maintain consistent humidity levels. Water regularly, allowing the soil to dry slightly between waterings.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to monitor humidity and light conditions, adjusting as necessary.
Winter
In winter, water less frequently, about every 2-3 weeks. Keep the plant in a warm area, away from drafts, and reduce fertilization to once every 2-3 months.
