Origin and History
The Philodendron red sun is native to Central and South America. The red sun gets its name from the Greek words “Philos” and “dendron,” which mean “love” and “tree,” respectively. The specific epithet “red sun” refers to the color of the leaves when they are young.
It belongs to the Araceae family and is botanically known as Thaumatophyllum bipinnatifidum ‘Sun Red.’ Due to its compact size and bushy growing habit indoors, it fits in any space. This plant can be grown indoors and outdoors, but it grows bigger outdoors than the pot.
The Red Sun is one of the best houseplants for purifying the indoor air as it absorbs harmful toxins like formaldehyde, benzene, carbon monoxide, etc.

Philodendron Red Sun Care Guide
Light
Red Sun philodendron needs good lighting conditions to thrive well. Medium to bright indirect light is ideal for its optimum growth. It will not do well in low-light conditions as it needs good light to maintain its vibrant colors.
Six hours of daily indirect sunlight will do best for it. If you can’t find any place in your home that receives good indirect sunlight, you can also grow it under fluorescent lighting; increase the exposure to 10 hours.
Likewise, only place your plant in low light conditions for a short time. It will cause the plant to lose its beautiful colors, and the plant will also become leggy toward the light.
If the low light conditions last too long, the leaves will become weak and start to drop. So, keep your plant under plenty of bright light.
But remember that the light should be indirect as too much direct sunlight will scorch the leaves and cause them to turn brown. If you are growing the Red sun outdoors, place it in a shady spot where it will be sheltered from the harsh afternoon sun.
Soil
Well-draining loose soil is what the red sun needs to grow. This is the best type of soil for Philodendron plants as it reduces the risk of overwatering.
Heavy and compact soils retain water for a long time, leading to waterlogging and eventually killing the plant. This is because roots need oxygen to stay alive, and compact soil deprives them of it.

Water
Watering this plant is tricky, but once you get the hang of it, it will be a breeze! Philodendrons need to be watered regularly to keep the soil moist but not soggy. When you water your plant, ensure all the water has drained out of the holes at the bottom of the pot.
This will help prevent waterlogging, damaging the roots, and killing the plant. Allow the topsoil to dry out completely before watering again. The watering frequency will depend on your home’s light conditions and temperature, as it needs more water when grown in bright light and warm temperatures.
In low light and cooler temperatures, it will require less water. Likewise, it will need more water during the spring and summer months and less water during the fall and winter months.
Just keep a simple rule in mind while watering your plant it’s always better to underwater your plant than overwater.
Fertilizer
Fertilizing the Philodendron red sun is essential to keep it healthy and promote its growth. Feed your plant with a balanced fertilizer once a month during the spring and summer months.
Stop feeding it during the fall and winter, as the plant will be dormant. You can use any standard liquid fertilizer for Philodendron plants. Just make sure to dilute it to half the recommended strength before applying it to your plant.
You can also go for slow-release fertilizer granules. It will reduce the frequency of fertilizing to 2-3 times a year, and you won’t have to worry about over-fertilizing your plant. Remember that in the case of fertilizer, less is more.
Over-fertilizing your plant will damage the roots and cause the leaves to brown. If you suspect that the salts from the fertilizer have accumulated in the soil, leach the soil with plenty of water to remove them.
You can use an organic fertilizer such as compost or manure to fertilize Philodendron red sun. Just make sure that they are fully decomposed before using them.
If you use fresh organic matter, it will burn the roots of your plant. Worm casting is also an excellent organic fertilizer for Philodendron plants. You can buy it from a garden center or use worms at home.
Temperature
Like other tropical plants, Philodendrons also prefers warm temperatures. The ideal temperature range for this plant is 65-85 degrees Fahrenheit.
There is no winter season in the tropics, so this plant does not tolerate cooler temperatures well. It will lose its leaves and eventually die if the temperature drops below 50 degrees Fahrenheit.
So, if you live in a place with cooler winters, bring your Red sun indoors before the temperature drops.
Usually, the household temperature is enough to keep this plant happy, but you can also put it in a room with a heater to give it some extra warmth during winter. Avoid sudden temperature changes, as it can shock your plant. Also, don’t place your plant near a heater or air conditioner.
Humidity
Your Red Sun likes staying in high humidity and prefers humidity around 60-70%. The average humidity level of your house will be enough to keep this plant happy.
Look at the leaves’ health to get an idea of the humidity level, as the edges of the leaves will start to turn brown if the humidity is too low.
You can place your plant in highly humid places like the bathroom or kitchen. You can increase humidity around your plant in the following ways:
- Group plants together: Your plant will feel happy sitting next to its fellow tropical friends as they help increase the humidity around each other.
- Use a pebble tray: Place your plant on top of a layer of pebbles and fill the tray with water. The water will evaporate and increase the humidity around the plant.
- Use a humidifier: This is the best way to increase humidity, especially if you have more than one Philodendron red sun plant.
- Mist the plant: Misting is a great way to increase the humidity around Philodendron red sun, but make sure not to mist the leaves too often as it will encourage fungal growth.
Pruning
The Red sun is a moderate grower and doesn’t need much pruning. You can prune it to control its size or shape. If you are growing it outdoors, it can reach up to 20 feet, so you might need to prune it to keep it under control.
But it doesn’t look too bad when left to grow freely. Because its vibrant leaves look more attractive as they get bushy, but if you see any dead or dying leaves, make sure to remove them.
Also, remove any yellow or brown leaves as they indicate the plant is unhealthy.
Repotting
Red Sun Philodendron likes to be moved or repotted sparingly. Once every 2-3 years should be enough. The best time to repot your plant is spring when the plant is actively growing.
But ensure not to disturb the roots too much as it will damage the plant. Use a well-draining
Pet safety/Toxicity

Propagation the Philodendron Red Sun
You can propagate Philodendron by Offsets, Cuttings, and Divisions. But the easiest and most common method is by divisions.
To propagate the philodendron red sun by division, you will need the following:
- A sharp knife or garden shears
- A pot for each division you make
- Philodendron red sun divisions
- Well-draining
potting mix
-Start by using a sharp knife or garden shears to cut through the Philodendron’s rhizome. Make clean cuts and disinfect your tools before and after use.
-Once you have made your divisions, pot each one up in its own pot using a well-draining
-Water each red sun division generously and place it in a bright, indirect light. Allow the soil to dry out somewhat between waterings.
With a bit of care, your Philodendron red sun divisions should take root and begin to grow.
You can also propagate Philodendron red sun by stem cuttings. Cut a stem with at least two leaves and remove the bottom leaves.
To propagate the red sun by cuttings, you will need:
- Use a sharp knife or garden shears to take a cutting from the Philodendron that is at least six inches long.
- Place the cutting in a pot filled with well-draining
potting mix .-Water generously and place in a bright, indirect light. - Allow the soil to dry out somewhat between waterings. With some care, your Philodendron red sun cutting should take root and grow in approximately two to three weeks.
You can also propagate Philodendron red sun by offsets. Philodendron red sun offsets are tiny plants that grow at the base of the parent plant.
To propagate Philodendron red sun by offsets:
- Remove the offset from the parent plant and put it in its pot filled with well-draining
potting mix . - Water generously and place in a bright, indirect light.
- Allow the soil to dry out somewhat between waterings.
