When the leaves first grow in, they often start out with a light burgundy color or a darker orange hue before deepening to the classic deep green look of these plants.

In this article weโ€™ll weave together some Rojo Congo plant care tips along with some history notes on this fascinating plant โ€“ itโ€™s a patented plant!

Letโ€™s get startedโ€ฆ

How often should I water my Rojo Congo?

As far as plant care goes, watering is the most common source of struggle for people. Luckily, the Philodendron family isnโ€™t TOO picky about water.

As with any plants, youโ€™ll want to establish a regular watering routine. How often you water will mostly depend on the time of year.

In summer you want to keep the soil moist to the touch, but not soggy! You can use your finger to check by poking in the top few centimeters of the soil before watering. If it feels wet, then you should let it dry out for longer.

Avoid overwatering! You donโ€™t want your plant to develop fungal issues or root rot. drainage is essential. Ensure that whatever vessel your plant is in, there are sufficient holes in the bottom to allow excess water to drain freely from the pot and away from the plantโ€™s roots.

The average watering routine is watering your Rojo Congo once a week in the summer.

During the winter, the plant isnโ€™t growing much so you can reduce the watering frequency.

Ideal Philodendron Rojo Congo humidity levels

In general, Philodendrons are pretty accommodating to different humidity levels. This is great news for Floridians because our humidity wonโ€™t cause them any problems.

If you live outside of Florida, then you can consider a small humidifier for your home. This isnโ€™t required by any means though!

Congo Rojos thrive in temperatures around 65 to 80 F.ย  While theyโ€™re fine with nighttime temperatures of 60 F, they are not cold tolerant and should be kept away from cold climates.

How much light does a Congo Rojo need?

Now that youโ€™ve got your red Congo Rojoโ€™s water requirements covered, the next major factor is light.

Congo Rojos love to get 3 to 4 hours of bright indirect light. Medium-light can work well for these plants. If you have to choose between too much light and not enoughโ€ฆ you should err on the side of not enough.

But youโ€™ll need to avoid placing the Philodendron Congo Rojo in low light.ย  The leaves and stems are prone to rot in these conditions, and over-watering becomes much easier as the water isnโ€™t used up completely.

Prevent the leaves from receiving too much direct light since that will burn the leaves and turn them a yucky brown color.

A window sill that gets direct sunlight during morning hours is perfect.

An outside shaded area works well if you want to grow this plant outdoors as part of a landscape design.

How to propagate a Red Congo plant

Now that youโ€™re growing one plant well, itโ€™s time to propagate! Propagating the Red Congo takes some patience, but the process is fairly simple and straightforward!

Follow these instructions to propagate your Red Congo:

  • Select a healthy stem to propagate – Using sharp, clean scissors, cut a stem from the very base of the central stalk at a 45-degree angle.
  • Place the stem in water – Find a clear glass (so you can see the roots) and fill it with water. Make sure only the stem is submerged, and no leaves are sitting in the water.
  • Place in indirect sunlight – Do NOT place the stem in direct sun, and remember to be patient! New roots may take a few weeks to begin forming.
  • Transfer to soil – After the roots are at least two inches long, transfer to indoor potting soil. A small pot is best โ€” no larger than 6โ€ in diameter.

All done! Now you just to keep the soil watered and drain so that the plant can grow as healthy as itโ€™s momma.

Philodendron Imperial Red vs Rojo Congo


The reason these two plants are so similar is that the Philodendron โ€œRojo Congoโ€ is actually a cross between Philodendron โ€Imperial Redโ€ and Philodendron Tatei.

Weโ€™ll lay out the differences between these two plants more technically in a moment, but in general the difference is just size and color. The Rojo Congo grows larger and faster than the Imperial Red. Plus the leaves are broader and darker compared to the elongated bright green leaves of the Tatei.
As per the official patent:

โ€œPlants of โ€˜Rojo Congoโ€™ are distinguished from plants of the female parent, commercial Philodendron cultivar โ€˜Imperial Redโ€™ disclosed in U.S. Plant Pat. No. 6,337 by the following characteristics:

1. Plants of โ€˜Rojo Congoโ€™ are larger, have more outwardly spreading and open growth habit than plants of โ€˜Imperial Redโ€™.

2. Plants of โ€˜Rojo Congoโ€™ are more vigorous than plants of โ€˜Imperial Redโ€™.

3. Leaf blades of โ€˜Rojo Congoโ€™ are thicker, larger and more ovate than leaf blades of โ€˜Imperial Redโ€™.

4. Petioles of โ€˜Rojo Congoโ€™ are longer and thicker than petioles of โ€˜Imperial Redโ€™.

5. Mature leaf blades of โ€˜Rojo Congoโ€™ are darker green with greater contrast between midrib and surrounding tissue than mature leaf blades of โ€˜Imperial Redโ€™.

6. Mature petioles of โ€˜Rojo Congoโ€™ are dark purple-brown, whereas mature petioles of โ€˜Imperial Redโ€™ are brownish-green.

7. Leaf petiole sheaths of โ€˜Rojo Congoโ€™ are longer and darker red-purple than leaf petiole sheaths of โ€˜Imperial Redโ€™.

8. Plants of โ€˜Rojo Congoโ€™ have more and thicker air roots than plants of โ€˜Imperial Redโ€™.โ€
