Philodendron Rojo Congo

Philodendron Rojo Congo Soil

Like most Philodendrons, Philodendron Congo Rojo enjoys a loose, airy, growing medium with ample drainage that will adequately retain water. A commercial cactus or aroid potting soil will be ideal for this Philodendron. Additionally, organic matter incorporations such as compost, coco coir, or sphagnum moss may be added to boost the soil. Soilless mixes made of peat moss or perlite will also work. 

Philodendron Rojo Congo Fertilizer

This Philodendron will prefer slow-release granular fertilizers or organic fertilizers such as worm castings over liquid fertilizers. In spring, incorporate a couple of handfuls or work castings into the soil around the base of the plant. Alternatively, a granular slow-release fertilizer may be applied. Ensure that you follow all label instructions. 

Philodendron Rojo Congo Watering

It should be noted that this Philodendron will not tolerate prolonged drought periods, as some other philodendrons do, and should remain consistently moist. On the other hand, this plant will not tolerate excess water either. On average, Philodendron Rojo Congo will need to be watered around 2-3 times weekly during the summer and around every ten days during the winter, depending on growing conditions. To test moisture levels, stick a finger into the soil surrounding the plant. When the soil has dried entirely up to a depth of about two inches, it is time to rewater. 

Philodendron Rojo Congo Light Requirements

Philodendron Rojo Congo requires a great deal of light to retain their brilliant color. Bright, indirect light, such as from an east or west window, is an ideal location for this plant. Do not allow this plant to sit in direct sunlight for more than an hour daily, as this will cause leaf scorching. This Philodendron may also be supported with fluorescent lighting if your home does not have enough natural sunlight to support the needs of Philodendron Rojo Congo. If the leaves of your Philodendron start to fade, it is likely an indicator that your plant is not receiving enough light. 

Philodendron Rojo Congo Temperature & Humidity

Philodendron Rojo Congo likes to remain warm, being bred from tropical plants and will thrive in an environment with a temperature between 65 to 85 degrees Fahrenheit. Keep in mind that this plant does not like temperature fluctuations and should not be kept next to heaters, air conditioners, drafts, or cold windows. This Philodendron is not resistant to frost and does not like cold temperatures or extreme heat. Do not allow this Philodendron to reach temperatures below 55 or above 95 degrees Fahrenheit, as this may cause permanent damage. Give this plant humidity levels of around 40 to 60%. If your home is on the drier side or during winter, provide the plant with a humidifier.

Repotting Philodendron Rojo Congo

Philodendron Rojo Congo is a rapid grower. It will likely need to be repotted annually in early spring to allow more room for the roots to grow and refresh the soil in its first few years. When your plant has matured, it will likely only need to be repotted every two to three years or whenever you see roots appearing through the drainage holes in the container. Alternatively, you can repot your Philodendron in a large container that is 16-18″ in diameter and refresh the growing substrate every couple of years to freshen up the soil. 

Philodendron Rojo Congo Maintenance & Pruning

Although it will only reach a height of two feet tall, this Philodendron has a habit of getting top-heavy, so choose a container accordingly. This Philodendron will not need to be pruned. Instead, discolored and dead leaves can be trimmed using sharp, clean shears. 

Philodendron Rojo Congo Propagation

Philodendron Rojo Congo can be easily propagated through stem division. First, identify the node and cut a stem from the plant utilizing sterilized garden scissors about a half-inch below the node. Ideally, select a stem that has several leaves and aerial roots. Next, place the cutting into a container with water in indirect light. Periodically change the water, and you should see roots within two months. Once the roots have reached about a .5-1′ in length, you may plant them into a new container with fresh soil. Alternatively, you may propagate this plant through root division and planting the offset plantlets.
