Philodendron Red Emerald Care

Red Emerald Philodendron is a beautiful plant to have at home. What is more exciting is that it is easy to grow and take care of. Keep the information below in mind before bringing the plant home, and you will have a rewarding experience.

– Water

The Philodendron with red stems is a relatively easy houseplant to grow. The only problem that you might face with it is overwatering, which leads to root rot. The plant can forgive one or two watering, but do not neglect to water your plants for long. 

Philodendron Red Emerald loves moist soil. Avoid completely drying the soil in between watering. One of the common signs of overwatered plants is yellow foliage. The best way to control overwatering is to check the soil before watering.

– Light

Philodendron Red Emerald likes to grow in partial light. Always shelter the plant with direct exposure to sunlight. You can do this by placing it away from a south-facing window that may scorch the leaves. Alternatively, you can place the plants close together to filter light.

Light Management for Red Emerald

Bright indirect light will encourage deep red stems. Low light will make the stems longer and keep leaves small. It is important to note that the plant grows best when indoor temperatures are maintained at 65 degrees Fahrenheit.


Soil also plays an important role in maintaining soil moisture. Choose a well-drained mix of soil paired with organic matter. You can use perlite, peat moss, or coco coir for this. The idea is to drain excess water while retaining moisture.

Here are some of the ingredients that you can use:

  • Coco Coir 
  • Orchid Bark
  • Perlite
  • Activated Charcoal
  • Worm Castings
  • Sphagnum Moss  

In short, it can thrive even when slightly underwater but will die with overwatering. Similar to other aroids, Philodendron Red Emerald will also like moist soil, which can be achieved with balanced watering. 

– Humidity

Philodendron Red Emerald will thrive in indoor humidity that is between 40 to 50 percent. This is considered moderate humidity. If the humidity level crosses 70 percent, the plant will shoot out more aerial roots.

It can be beneficial if you are trying to propagate it. Higher humidity will also encourage bigger foliage and thicker stems. You can increase humidity by installing a humidifier or by placing plants close together. 

– Fertilizer

As a potted plant, Philodendron Red Emerald will need fertilizer during the growing season. There are many options in the market, but the NPK ratio of 7:9:5 can be perfect. It will offer sixteen essential nutrients to the plants.

Fertilizers that are high in salt content can change the pH level of the soil. Higher pH can cause root burn. Always try to choose natural, well-balanced fertilizer or dilute the solution. 

You can add diluted fertilizer to the watering can and use it gradually for each watering. During the growing season, apply the diluted feed twice a week. It means a quarter teaspoon in four liters of water. This method will protect your plant from burned roots.

In winters, stop fertilizing and let the plant stay dormant. It is essential for its robust growth in spring and summer.


The philodendron red emerald can survive in a small pot or be root bound, but it is not ideal. Changing the pot as soon as the pot becomes clogged with roots is important. The plant will have more space to grow and love the fresh soil that will boost its growth.

Repotting Red Emerald

Usually, the plants that are sold at nurseries are fully grown and need to be repotted. When you repot your plant, keep the following points in mind:

  • Select a pot with drainage holes
  • The new pot should be two inches bigger than the old one
  • Make sure the potting mix is fresh and of high quality. Use the guide above to create your own


Philodendron is very easy to propagate. Who doesn’t want more of this beauty? Let us show you how to multiply your plants without a hassle. Our simple guide will help you learn step-by-step propagation:

– Air Layering

  • Select healthy looking strong stems with aerial roots growing from the leaf nodes.
  • Take moist moss and wrap it around the node roots.
  • Press and wrap the moss around the stem, and then with the help of foil or plastic, secure it around the stem.
  • Leave the top and bottom of the wrap open so that the roots can thrive.
  • Mist the moss regularly until they grow stronger in the next couple of weeks.
  • If the attempt fails, then do not worry; try again.
  • Once the roots are strong, cut and plant them in the pot.
  • Follow the above guide for caring for your new plants.


Although Philodendron Red Emerald is an easy-to-grow plant, it may still show signs of illness. Most of the problems come from overwatering. Let us look at each symptom and learn to resolve them:

Yellow leaves of Philodendron Red Emerald happen when there is root rot. Root rot is caused by overwatering. Always check for moisture before watering. If the soil is wet, do not water it. Make sure the soil is also well-drained.

If the problem goes out of hand, the only solution is taking cuttings and growing new plants.
