Philodendron Red Emerald

Philodendron Red Emerald, known as Philodendron erubescens, is a stunning tropical plant native to Colombia. Its glossy leaves have a rich emerald-green color with red hues, adding a touch of elegance to any indoor space. The leaves are large, and showy, and grow vigorously on the Araceae family of philodendrons.

The leaves are heart-shaped and can grow up to 12 inches long. There are a variety of colors to match the plant’s deep red petioles, and the leaves can range from deep green to bronze, burgundy, and even red.

Anthocyanins, which are pigments produced by plants in response to environmental cues such as light intensity and temperature, give a red color to the leaves.

The Red Emerald Philodendron prefers bright indirect light for a more vibrant red color.

Avoid direct sunlight, as it can scorch the leaves and cause the soil to dry out, too.

How Much Light Does A Red Philodendron Need?

Philodendron ‘Red Emerald’ is an easy-going plant when it comes to lighting requirements. It prefers bright, indirect light, making it ideal for indoor environments with moderate levels of natural light. The right amount of light will usually be provided by placing your red Philodendron near a north or east-facing window. Direct sunlight should be avoided, as it can scorch the foliage and cause discoloration. Consider adding fluorescent lights to your indoor space if you lack enough natural light for your plants.

Philodendron red emerald soil

The soil you choose for your Philodendron ‘Red Emerald’ is crucial for its health and growth. This plant thrives in well-draining soil that retains moisture without becoming soggy. A mixture of regular potting soil with more ingredients, such as perlite or orchid bark, can provide the perfect balance. These additives enhance drainage capabilities, preventing the soil from becoming too compacted.

Water Requirement

Philodendron ‘Red Emerald’ enjoys moist soil, but overwatering can lead to root rot and other issues. Water your plant when the top inch of soil feels dry to the touch. Ensure that excess water can drain from the bottom of the pot, preventing waterlogging. It is important to remember that underwatering is generally better than overwatering for the health of your Philodendron. Check the moisture levels and adjust your watering schedule for a thriving plant.

Temperature And Humidity

Being native to the tropical regions of Central and South America, Philodendron ‘Red Emerald’ prefers warm and humid conditions. The temperature should range between 65°F to 85°F (18°C to 29°C) to promote optimal growth. Humidity levels of around 50% to 60% are ideal for this plant. If the air in your indoor space is dry, use a humidifier or place the plant on a tray filled with water and pebbles to create a humid microclimate. 

Fertilizer Requirement

To keep your Philodendron ‘Red Emerald’ thriving, it requires regular feeding with a balanced, water-soluble fertilizer. During the growing season, which spans from spring to early fall, apply the fertilizer every four to six weeks. To prevent root burning, dilute the fertilizer to half its recommended strength. Adjust the feeding schedule during the dormant period to once every two months. Always remember to water the plant before applying fertilizer to prevent root damage.

Red Emerald Philodendron Pruning Guide

Pruning is an essential aspect of Philodendron ‘Red Emerald’ care to maintain its shape and promote healthy growth. You can remove any yellowing or dead leaves by cutting them off at the base. Pruning also allows you to control the size of your plant and prevent it from becoming leggy. Cut back any long stems to encourage bushier growth. Always use clean and sharp pruning shears to prevent the spread of diseases and ensure the best results.

Philodendron Red Emerald propagation

Philodendron Red Emerald

Propagating Philodendron Red Emerald is a rewarding and straightforward process that can be achieved through stem cuttings. The key is to select a healthy, mature plant with several nodes on the stem. Taking a cutting below a node and removing any lower leaves will provide the best chance for successful propagation. Rooting hormone can be applied to encourage root development before placing the cutting in water or soil.

One fresh approach to propagation is using sphagnum moss as a rooting medium. This method provides excellent moisture retention and creates an optimal environment for root growth. Additionally, exposing the cutting to indirect sunlight while maintaining high humidity can support faster and healthier root development.

How Often To Repot Philodendron?

Repotting your Philodendron ‘Red Emerald’ is necessary every two years or when you notice the plant becoming pot-bound. This occurs when the roots occupy most of the available space in the pot. The best time to repot is during the growing season, which allows the plant to recover from the transplantation process. When repotting, choose a larger pot to provide ample space for root growth. Refresh the soil mixture and ensure proper drainage to support the continued well-being of your Philodendron.

Common Pests & Plant Diseases

Having a lush and healthy Philodendron Red Emerald can be a joy, but like any other plant, it is not immune to common pests and diseases. Taking proper care of your plant requires knowledge of these potential problems. We will explore some common pests and plant diseases that can affect your philodendron erubescens red, as well as how to prevent and treat them.


  1. Aphids: Aphids are tiny insects that can be overlooked but can cause serious damage to your Philodendron Red Emerald. They feed on the sap of the plant, resulting in yellowing leaves, stunted growth, and sticky residue. To control aphids, try spraying the plant with a mixture of water and mild liquid soap.
  2. Mealybugs: Mealybugs are another common pest that can infest your philodendron red erubescens. These soft-bodied insects suck the sap from the leaves, causing yellowing and wilting. They also leave behind a cottony white residue on the plant. To get rid of mealybugs, wipe the affected areas with a cotton swab soaked in rubbing alcohol. To control their population, you can also use insecticidal soap or neem oil.
  3. Spider Mites: Spider mites are tiny arachnids that often infest houseplants, including the Philodendron Red Emerald. They feed on the plant’s cells, leading to yellowing leaves, webbing, and decline. The presence of these pests can be discouraged by misting the leaves of your plant. If the infestation is severe, you may need to use insecticidal soap or neem oil.


  1. Root Rot: Root rot is a common disease that affects many plants, including the Philodendron Red Emerald. It is caused by overwatering or poorly-draining soil, leading to the roots becoming waterlogged and oxygen-deprived. Plants should be potted in well-draining soil to prevent root rot. If root rot is already present, you may need to repot the plant in fresh soil and trim off any affected roots.
  2. Leaf Spot: Leaf spot is a fungal disease that manifests as dark, water-soaked spots on the leaves of your red erubescens philodendron. It can be caused by overwatering, poor air circulation, or excessive humidity. To prevent leaf spots, ensure the plant is not crowded with other plants and that the leaves are kept dry. If a leaf spot does occur, remove and destroy affected leaves and adjust the growing conditions to prevent further spread.
  3. Bacterial Blight: Bacterial blight is a bacterial disease that causes brown, water-soaked spots on the leaves of your Philo Red Emerald. It can be spread through contaminated tools, water, or soil. To prevent bacterial blight, practice good hygiene and avoid overhead watering. If your plant is affected, remove and destroy infected leaves, disinfect any tools used, and adjust the watering practices to keep the foliage dry.

As beautiful and striking as the Philodendron Red Emerald is, like any houseplant, it can sometimes face issues that can hinder its growth and health. If you notice any signs of trouble, it’s important to address them to ensure a thriving and vibrant plant.

  • Yellowed Leaves: If you spot yellow leaves on your Philo Red Emerald, it could state various underlying issues. One common cause is over-watering, which can suffocate the roots and lead to root rot. So, underwatering can also result in yellowing leaves as the plant becomes dehydrated.

  • Brown Leaves: Brown leaves on your Philodendron Erubescens can be a distressing sight. The most probable cause of brown leaves is direct sunlight exposure. Although these plants thrive in bright, indirect light, excessive sun can scorch their leaves, leading to browning and damage. If your Philodendron Red Emerald is situated in a spot that receives intense sunlight, consider moving it to a more shaded area or use sheer curtains to filter the sunlight. Rotating the plant can also help ensure even and healthy growth.
  • Dark Leaf Spots Or Edge: Dark spots or edges on the leaves of your Philodendron Emerald may be a sign of fungal or bacterial infection. This common problem can be exacerbated by high humidity and poor air circulation. To combat this issue, ensure proper ventilation by placing your plant near a fan or open window. It’s also important to avoid overwatering and provide enough space between the leaves for air to circulate. If you notice any infected leaves, remove them to prevent the spread of the disease and keep your Philodendron Erubescens in optimal condition.
