Philodendron Red Emerald Profile

General Information

Philodendron Red Emerald (Philodendron erubescens) is a lovely, exotic, rare aroid and one of the most common vining houseplants in the Araceae family. It is a tropical plant that is a fleshy, terrarium-friendly vine hybrid originating from the rainforests of Colombia and Costa Rica. 

Commonly, it is also called “Blushing Philodendron” or “Red-leaf Philodendron”. It has attractive heart-shaped foliage with colors that blend between green and burgundy red and a striking red-colored stem that adds tropical elegance to the interior decoration.


The botanical name “philodendron” comes from the Greek words “philo“, meaninglove” and “affection“, and “dendron,” meaning tree. So the Philodendron is loosely translated as “tree huggers” with these meanings. This is because they are often seen in the wild as tree climbers.

The specific epithet “erubescens” loosely means “that which turns red or blushes”, describing the reddish hue of the whole plant.


Philodendron Red Emerald is a flowering plant with deep red blossoms. It usually blooms with a pinkish-red cone-shaped spathe and spadix. The flower looks like an Arum lily. However, don’t expect it to bloom, especially if you keep it inside. Most people grow this plant for its foliage rather than its flowers.

Season Of Interest And Purchasing

Late spring to early summer is the blooming period for Philodendron Red Emerald. The flowers can be harvested to be put in a vase or any interior containers. This is also the best time to purchase this plant because this is its growing season.

This plant enhances the interior spaces with exotic elegance, as well as improves air quality. Philodendron Red Emerald is available in aroid plant nurseries and in garden stores.


Red Emerald is an aggressive climbing plant with long, elongated green foliage with red highlights. It can grow about 12 feet (3m) tall when cultivated and become completely epiphytic in the wild. However, it will only reach a maximum height of 3 feet (36 inches) in an indoor setting.

This plant develops quickly and in an upright pattern. It will be able to grow upward and bear its weight with the aid of a moss pole or trellis.

Care Tips

Care tips

Light Requirement

The Philodendron Red Emerald is an epiphyte, which means it climbs trees. Hence, they are prone to scorching and tend to be sensitive to direct light. This plant prefers six to eight hours of indirect light that ranges from moderate to bright. This will promote vibrant color, deep red stems, and long and elongated leaves. 

To avoid damaging the leaves from sunburns and changing the color of the foliage, always remember to keep this plant out of direct sunlight.

Temperature Requirement

The Philodendron Red Emerald, a native of Central and South America’s tropical regions, prefers to grow in an environment with constant temperatures between 70 and 80 degrees Fahrenheit (21 and 29 degrees Celsius). A plant will grow without any issues if you provide it with a comfortable temperature. 

Please don’t leave them outside when it is below 50 degrees Fahrenheit because they are not frost-or cold-resistant. The plant’s growth will be severely stunted, leading to small leaves, wilting, or even death under unfavorable temperature conditions.

Water Requirement

One of the most crucial parts of caring for a houseplant is providing it with the proper amount of water. Philodendron Red Emerald is drought tolerant and does not require to be watered frequently. This plant can tolerate infrequent watering. However, it prefers an even level of moisture, and it thrives in moist, well-draining soil. 

Maintaining moist but not soggy soil is essential. A plant’s roots may rot as a result of excessive watering. Hence, it is advised to water the plant once or twice every 7 to 14 days to make sure it receives enough moisture until the next watering. 

Humidity Requirement

For a more efficient photosynthesis, the humidity level is crucial. Philodendrons thrive in humid environments. Your Philodendron Red Emerald can tolerate humidity levels up to 50%-60% in homes. 

One way to keep your plant happy is by misting its leaves. You can spray fine mist above your plant’s leaves every 2-3 days on regular days, while you may need to do it daily during hot days. You can use a regular spray bottle.

Other ways to provide sufficient humidity are using room humidifiers (particularly around 40% humidity), pebble tray humidifiers, or simply grouping the house plants. This proximity among the plants can create a natural humid atmosphere, similar to their native environment.

Soil Requirement

Philodendron Red Emerald prefers moist soil that is not excessively saturated. The soil should be rich but light and airy. Fast-draining, high-organic-matter potting mixtures are ideal for them. This is to avoid becoming muddy or waterlogged. 

To make the soil less likely to compact and support the roots’ aeration, mix it with perlite, sphagnum moss, sand, coconut coir, or bark.

Fertilizer Requirement

Philodendron Red Emerald will need fertilizer during the growing season to supply it with the nutrients it needs to grow. In order to promote growth in the spring and summer, it is suggested to apply some slow-release fertilizer and feed once a month.

Furthermore, the 7:9:5 NPK ratio is the best choice for fertilizer. It will give the plants the essential nutrients they need to thrive rather than just survive.

It may also be helpful to flush the soil every once in a while, specifically about every four to five months, to avoid salt buildup. To do this, run water slowly through the potting mix for two to three minutes. You can resume with regular watering and feeding when the top 1 inch of soil has already dried.

Space Requirement

The Philodendron Red Emerald prefers an area with some shade, or, more precisely, semi-shade to shadow. To ensure that this plant receives the ideal quantity of light, place it close to a south-facing or east-facing window. Although it may be grown in soil or pots, it thrives in small spaces and attractive containers like terrariums.

Growing And Planting Tips

Philodendron Red Emerald Growing Tips


The Philodendron Red Emeralds are primarily propagated in two ways. It can be done via(1) Stem cuttings and via (2) air layering. Both methods are easy and straightforward and guarantee success in reproducing your plant. Below are the detailed steps to propagate your Red Emerald.

Propagation By Stem Cuttings  

The most common method of propagation is stem cuttings. They are easily propagated by obtaining a stem cutting with at least one node and one leaf. Then, trim the stem to a length of 4 to 6 inches and make a small pot with perlite and sphagnum moss that is moist and evenly divided. The moss ought to be moist but not drenched. 

The cutting can be handled as a distinct plant and allowed to grow where it is wanted once the roots have taken hold. Transfer new roots to potting soil when they reach a length of 1 to 2 inches. 

Propagation By Air Layering

This method helps produce roots on the stems of indoor landscape plants that have become “leggy” through the loss of their lower foliage. Choose stems that appear healthy and sturdy, with aerial roots developing from the leaf nodes. After choosing a stem, wrap the healthy node with roots and a pole in some moist sphagnum moss.

This helps in supporting thinner stems that can’t stand up against the weight of the moss and the pole on their own. Next, wrap the node in a glass or moist cloth to  keep the moss’ moisture intact. To ensure the moisture level and monitor the sphagnum moss’s progress in rooting, remove the wrapping and check it once a week.


Philodendron Red Emerald requires pruning to thrive. It will help them grow well and look nicer. Prune off dying branches, stubs, and unwanted overgrown parts using sterile pruning shears. Do it regularly during the spring or fall to ensure better growth.

Potting And Repotting

It is recommended that the Philodendron Red Emerald is repotted once a year when they are young. After reaching maturity, they should be repotted every two years. Doing so gives you the chance to refresh your potting mix and encourage plant growth. It also prevents your plant from becoming rootbound, further helping with the drainage.

Problems And Troubleshooting

Philodendron Red Emerald Problems


Overwatering Philodendron Red Emerald causes your plants to drown. This results in stunted, slow growth with yellowing leaves. Plants might get leaf scorch or leaf burns, root rotting, and even death, in worst situations.

Consider altering the pot and soil to provide effective drainage to fix this. A properly draining soil will greatly reduce the impact of overwatering.


Underwatering Philodendron Red Emerald causes dry leaves, brown tips, leaf drops, withering, and leaf curling. 

To preserve the health of the plant, maintain the watering pattern and supply the plant with bright, indirect light to help it survive. Water it thoroughly, making sure to provide water to the roots, and try decreasing the time between waterings. 

Nutrient Deficiency

Plants can suffer from deficiencies when growing conditions are inadequate, and the plants are unable to absorb nutrients from the soil. 

Philodendron Red Emerald is best fertilized with nitrogen, phosphorus, potassium, and sulfur to encourage green, lush growth. Deficiencies of these nutrients result in yellowing and stunted development of your Philodendron Red Emerald.

Flowering Problems

The plant may produce flowers in its natural habitat, but not very much when cultivated indoors. When a mature plant blooms, consider cutting the buds to create a place for bushier foliage.
