Philodendron Rojo Congo Plant Size

The Red Congo grows to about 24-36 inches tall as a mature Philodendron plant. Because of its height, light needs, and high humidity requirements, you can place it in a kitchen or bathroom – or near an east or west-facing window.

Philodendron Rojo Congo Care Needs

Your Philodendron Rojo Congo, like any other houseplant, grows well with proper care. The Congo Red, which adores warm weather and has extravagant  leaves, wants evenly moist soil throughout the year.

You typically want to water your Philodendron when the top inch of soil is dry to touch. Allow plenty of time for excess water to drain out of the pot’s draining hole. Similarly, this lovely plant needs bright indirect sunlight to thrive.

Check out the thorough care guidelines below for more specific advice.

Care Difficulty

Philodendron Rojo Congo is easy to grow. The amount of light and well-draining soil are important factors for this rare plant option.

Growth Rate

The Philodendron Rojo Congo plant grows 24-36 inches tall and grows fairly fast. Their growing season is between early spring and summer.


A large terracotta or ceramic pot is ideal for Philodendron plants. Also, while it may seem obvious, make sure your pot has a bottom hole.

Lack of drainage is a major threat to most plants, including Philodendron Rojo Congo. 

As your Philodendron Rojo Congo grows, you might consider upgrading from your current pot to a new pot for best results or on an as-needed basis. Typically, this will occur every year because Congo Reds grow quickly.

In between potting changes, you can refresh your plant’s old soil with a new organic potting soil to freshen up your Philodendron plant each year.


When watering Red Congo, aim for an evenly moist potting mix. Inspect the soil with your finger. When the top inch of soil feels dry, water your Philodendron.

Overwatering is a leading cause of indoor plant death. When in doubt, under water rather than over water the Red Congo. Underwatering can stunt growth, but it can usually be corrected with time and patience.

Also, always use well-draining soil and a pot with drainage holes.

Avoid putting your Philodendron Rojo Congo in direct sunlight, as this could severely damage or even kill it.


Philodendron Rojo Congo’s light requirements range from bright indirect light to part shade. You’re trying to simulate the conditions of South American rainforests. Pacing this plant near an east or west-facing window works well in most situations. Plan to keep this plant in bright indirect light for 3-4 hours per day.

If the leaves of your Red Congo begin to turn yellow or become scorched, you’ll know it’s been exposed to too much light. On the other hand, if this plant does not receive enough light, its stems may become long and leggy.

Drooping and yellow leaves may indicate overexposure to light, but they may also indicate a lack of fertility. More information can be found in our fertilizer section.


For the Red Congo, organic potting soil is a suitable choice. Use coco coir, orchid bark, perlite, activated charcoal if you make your own. Keep in mind that Rojo Congo prefers an evenly moist growth medium, and your soil type should accommodate this.

Pests And Common Diseases

Things can go wrong even with expert care. Pests, diseases, and general issues arise from time to time. Unfortunately, the Philodendron Rojo Congo is not resistant to many diseases or pests. Here are some common issues.

Brown Leaf Tips

If the tops of your Red Congo start to brown, it may be due to too much sunlight or not enough humidity in your home.

Drooping Leaves

This can be caused by overwatering and fertilization of the Philodendron Rojo Congo. Mealybugs can also cause these issues.

Yellow Leaves

Yellow leaves can be caused by several factors. It may lack sunlight or receive too much or too little water.

Yellow leaves should be pruned to promote new growth and stop deterioration. Yellow leaves can be unappealing. Pluck or trim the leaves with a sharp, clean pair of shears. This plant is unafraid of being beaten.


Aphids can eat the leaves of the Congo Rojo, causing them to turn black and brown.

Use insecticidal soap or neem oil to treat aphids, or make your own with Ivory Liquid. Try to avoid products with perfumes and other harmful ingredients. Mix the soap and water (starting with one teaspoon per gallon and increasing as necessary). Spray the plants, focusing on the undersides of the leaves.


Mealybugs may infest your Philodendron Rojo Congo. These tiny parasites damage your Philodendron by inserting a feeding tube into the plant tissues and sucking on the sap. Mealybugs can weaken or kill your Red Congo.

To get rid of them, rub rubbing alcohol on the lanceolate leaves and stem. Using neem oil as a preventative spray is also a good option.

Root rot is a plant disease caused by overwatering, poor drainage, or soil fungi. Root rot is difficult to treat, so prevention is the best option.
