The one place to avoid is somewhere it receives direct sunlight. Too much harsh sun will cause its leaves to scorch. You’ll notice this as its leaves will have brown, crispy spots.
In low light conditions, you likewise need to observe how the plant responds. When it gets too dim, your Philodendron Rojo Congo will become spindly and leggy. It will also become less bushy.
This is a sign that it wants more light. And, that you should move it.

That said, do watch out for extremes.
While the plant can tolerate hot conditions, it won’t be happy staying at 100 degree or higher climates.
More importantly, it is less tolerant of the cold. Don’t keep it somewhere it can get as cold as 40 degrees or lower. Ideally, once temperatures get to 50 degrees, move it to somewhere toastier.
One sign that it is struggling from the cold is that it will begin to drop its leaves. As such, when you see this, you want to move it.

As such, it is important to allow the top 1 to 3 inches of soil to dry up between waterings. You can test this by sticking your index finger into the soil.

Philodendron Rojo Congo Fertilizer
Philodendron Rojo Congo are heavy feeders. As such, in addition to rich, fertile soil, it needs to be fed regularly during its growing season to achieve the best results.
You can use a balanced liquid fertilizer every 2 to 4 weeks during spring and summer. Then, cut back to about every 6 to 8 weeks during winter.
Alternatively, you can likewise go with slow release fertilizer. This will reduce the frequency of feeding. And, it likewise cuts the risk of salt buildup in the soil.
If you do opt for slow release fertilizer, apply 2 to 3 times a year.
Slow plant growth or small leaves means it either is not getting enough light or plant food. So, check both and eliminate one before trying to fix the problem.
Often, it is easier to adjust light exposure. So, start with that.
On the other hand, pale colored leaves means that the plant lacks calcium and magnesium. These are two micronutrients philodendrons needs.
If this should happen, check if your fertilizer has the too components. If not, get a product that has them.
Your Philodendron Rojo Congo does not need a lot of pruning. It is a slow grower. Although it will eventually get as tall as 4 feet indoors.
That said, if you want to do any major pruning, the best time to do so is during the spring or summer. This often involves trimming it to its desired shape and size.
At other times of the year, you can do some maintenance work as well if you see anything that needs fixing. A few of these include:
- Removing dead, or discolored leaves. As long as it is just a few leaves, you can do it any time of the year. Leave the rest for spring or summer. The plant naturally sheds leaves every 30 to 60 days. So, you can take out a couple or so every now and then.
- Cut out parts of leaves that have brown spots. You can use a sterile pair of scissors to do this. Just cut out the section that’s affected and reshape the leaves.
- Cleaning. You can use cloth and wipe down the leaves. This is a good way to inspect the leaves as well. Removing dust and debris also helps them collect from light.
Philodendron Rojo Congo Propagation
Your Philodendron Rojo Congo can be propagated very easily. The most common way houseplant owners do this is via stem cuttings.
Here’s how to propagate Philodendron Rojo Congo from stem cuttings.
- Pick out a healthy stem with at least a couple of nodes.
- Using a sterile pair of sharp scissors or pruning shears trim off the stem cuttings. Take a 4 to 6 inch cutting.
- Place the stem cutting into a glass or jar filled with water. Make sure to remove any leaves that will get submerged.
- Keep the jar in a bright place that does not get direct sunlight.
- In about 2 weeks or so, you should see roots developing in the water. Allow the roots to grow to about 1 to 2 inches long.

How to Repot Philodendron Rojo Congo

Before you repot, always check. Take a look at the drainage hole at the bottom of the plant. This is often the first spot where the plant tries to come out. Its roots will peek out from the hole if it has outgrown the container.
Similarly, touch the soil to see if it feels loose. Once the roots outgrown the space they’re in, they’ll try to muscle their way out. This loosens the soil.
Here’s how to repot your Philodendron Rojo Congo.
- Find a good spot to get dirty. You can do this in a large sink (if you have one), outside int the grass or place newspaper on the floor indoors.
- Gently side root ball out of the pot. The more pot bound it is the harder it will be to get out. You can water beforehand to loosen the soil up a bit to make this easier.
- Brush off any excess soil or dirt. Make sure the roots are healthy as well.
- Add fresh, rich, well-draining potting soil to the new container. Use a container that’s 2 inches wider in diameter.
- Place the root ball in. Then, fill the gaps with soil.
- if you don’t want the plant to grow any bigger, clear out a good part of the soil in the root ball and use the same container with fresh potting soil. Alternatively, if the roots are getting too big for the pot, prune the roots. By keeping the plant in the same container, you can maintain its size for the rest of its life.
- Water the soil thoroughly.
- Place the plant in bright, indirect light.
Don’t worry if the plant’s growth stalls for the next 2 to 4 weeks. This is normal as it recovers from the shock of being transplanted. It will likewise adjust to its new home during that time. After that, it will start growing again.
Like other philodendrons, keep the Rojo Congo away from pets and children. It is toxic to people, dogs, cats and horses.
