Philodendron Red Emerald: (#1 Care Guide For Philodendron Erubescens)

If you are a Philodendron enthusiast, then the Red Emerald has to become a part of your garden, whether indoors or outdoors! This plant is a rare beauty, but it is incredibly easy to care for and will reward your care with many years of growth!

The Philodendron Red Emerald is a fast-growing vine plant that will grow indoors or outdoors. Easy to care for, this exotic and beautiful plant will complement any growing space or garden because of its attractive red-veined leaves, deep red stems, and vase-like flowers.

Native to the rainforests of Columbia and Costa Rica, the Red Emerald Philodendron is an extremely fast-grower. Unlike the Imperial Red Philodendron that grows into a bush, the Red Emerald Philodendron is a climbing, vining plant. It could easily reach a height of 6.5 feet (1.9 meters) with a spread of 5 feet (1.5 meters) in its natural jungle habitat. Let’s discuss this beautiful plant!

How To Tell In Your Philodendron Is A Red Emerald

Most Philodendron plants have one thing in common – big green heart-shaped leaves. What makes the Red Emerald Philodendron unique are the deep red veins on the top of the leaves with a coppery tinge on the underside of each leaf. The Red Emerald stems, known as petioles, are a deep red color.

The leaves only become a shiny, dark green once the plant matures, although the stems remain a rich red wine color throughout its life span.

Characteristics Of The Red Emerald Philodendron

The Philodendron Red Emerald is the red variety of the Philodendron Erubescens, a member of the Araceae family. Araceae plants include Peace Lilies, Monsteras, and Pothos and are collectively and colloquially known as Aroids, which, loosely translated, means that they all belong to the Arum family.

They all belong to the arum family because of their flower style, known as a spadix or a flowering spike. Each spadix is protected by a fleshy, deep red, vase-shaped false leaf called a spathe that acts as a large sheath enclosing the spadix. The spathe unfurls to reveal a beautiful deep-red flower with the spadix in the center.

Growth Rate And Size

Other than love and care, this fast-growing plant does need a lot of space to grow in as, when fully grown, it can spread to a width of 49 inches (1.25 meters) and, growing outdoors, can grow to be 12 feet (3.70 meters) tall! The Red Emerald Philodendron will not grow larger than around 3 feet (900 cm) tall as a houseplant.

How To Care For The Red Emerald Philodendron

Although this stunning plant is easy to care for, it does need some care to keep it growing as it should. It will thrive in the right conditions and with some regular maintenance.

Temperature And Humidity Requirements

As the Red Emerald Philodendron is native to the rainforests, its natural habitat is hot, humid, and crowded.

Ideal temperatures for optimal growth are between 70 and 90 degrees Fahrenheit (21 and 32 degrees Celsius). Their overall wellbeing will be affected if the temperature dips to below 60 degrees Fahrenheit(15 degrees Celsius) or climbs over 95 degrees Fahrenheit (35 degrees Celsius).

If you are growing this plant indoors, place a humidifier in the room to produce the required humidity levels of around 60%. You could mist the leaves with a spray of water often throughout the day.

If you are running a furnace or air-conditioner, remember to keep the air moist. These resilient indoor growers thrive on humidity and will rebel against dry air by showing brown tips on the very tips of their leaves.

Grouping several philodendron plants together could provide the high humidity levels required to thrive by creating a mini biome that allows the plants to share humidity resources.

When growing outdoors, be careful where you plant them as they are not frost-resistant or cold-hardy!

Watering Guide

When it comes to watering, rather err on the side of underwatering instead of overwatering. The Red Emerald Philodendron will survive if it misses out on a scheduled watering session or two, but don’t let it completely dry out between waterings.

Water the plant more often when the weather is hot and cut back during cooler temperatures. Avoid wet, soggy soil! Check daily to see if the soil is moist. If the soil is damp, add enough water to ensure it drains through the soil and into the tray. Empty the tray after the water has drained through.

When growing outdoors, the Red Emerald Philodendron can tolerate rain daily as long as their growing medium is fast-draining.

If the plant receives too much water, the leaves turn yellow, and the roots could develop root rot or fungus problems.

Light Guide

The Red Emerald Philodendron would climb high to reach the light in their natural habitat. In an indoor environment, they will only receive indirect or filtered sunlight, stunting their growth. Place them near a screened window or a spot where they will receive indirect sunlight for 2 – 3 hours during the early morning or late afternoon.

Strong sunlight will burn and discolor the leaves. Moderate to bright indirect or dappled sunlight will produce brighter red stems. The bright green leaves could fade to an off-lime or mild yellow color during the cooler winter months.

Soil And Potting Requirements

Repotting Philodendron

The correct soil is crucial for this plant to grow as it should. The Red Emerald Philodendron enjoys moist but not soggy soil and should always be planted into a pot capable of draining away excess water.

 The best soil to use in any potting mix should always be fast draining and contain an abundance of organic matter. Perlite, sphagnum moss, coconut coir, and bark can be added to the soil to keep it airy and lightweight enough to carry air to the roots.

Your local Garden center should stock pre-made soil mixes designed specifically for philodendron plants.

Fertilizer Requirements

The Red Emerald Philodendron does not need regular fertilizing, nor does it require specialized fertilizers, but a small application of fertilizers during the Spring and Summer growing months will undoubtedly help the plant grow more vibrant and produce longer leaves.

Simply add a slow-release fertilizer to the soil when potting or repotting the plant, or use a diluted all-purpose houseplant fertilizer once a month.

Too much fertilizer can cause fertilizer burn on the plant or a mineral build-up in the soil, so don’t use too much and only use a weak solution. Never apply fertilizer during the late fall or winter months, as the plant needs the cooler season to rest.

Quick Care Tips For The Red Emerald Philodendron

Now that you know the basic requirements for looking after your Red Emerald Philodendron, to keep it growing as it should, there are a few necessary basic care requirements:

Pruning Guide

The only time you should prune the Red Emerald Philodendron is when they are too long for the space they are growing in or when the plant becomes too leggy.

Only prune during the Spring of Fall. Shape each plant, remove any discolored or damaged leaves, and cut back any leggy or long vines. The occasional pruning will keep the plant looking tidy and in shape!

Potting And Repotting

While the plant is young and still growing, it will outgrow its pot every year. Once the plant is established, it will slow down, and repotting should be less frequent.

While the Red Emerald Philodendron can cope with being root bound, it should be moved to a bigger pot once its roots start to curl around the pot’s base.

Once the established plant is placed into its forever home, ensure a suitable pole or trellis as support. You might need to tie or clip the vine onto the pole to encourage the plant to grow upwards.

Repotting an established plant could be difficult because of the support structure and the weight of the plant. It might be better to leave the plant where it is and instead replace the top layer of soil in the pot.

You can divide a plant during repotting. Ensure that each section of the root has two shoots. Split the plant and place each in a new pot.

Propagation Facts

Growing new Red Emerald Philodendron plants from and the existing plant is relatively easy. There are two methods to use when propagating the Red Emerald Philodendron:

  • Rooting in water. Cut off an area from the existing plant with at least two nodes growing on it, about 4 to 6 inches (10 to 15 cm) long. Place the section in a jar of water for a few weeks and wait for the new roots to form – this could take several weeks or a few months. When the roots grow to about 1 inch (2.5 cm) long and are water rooted, plant into a pot containing a well-draining potting mix. Water often, but don’t overwater as the new cutting is fragile and too much water can kill it. Keep the soil moist.
  • Stem cutting method. Cut off an area from the existing plant with at least two nodes growing on it, about 4 to 6 inches (10 to 15 cm) long. Remove the lower two leaves from the section and plant the section in moist soil. The two lower nodes must be under the earth. Place the plant in a warm location away from direct sunlight. Ensure the soil remains wet but not soggy until new growth appears. Transplant into a bigger pot as the plant grows.
