Optimal growth and care are essential to maintain the signature pink variegation unless you have accidentally brought a fake plant.

Read on to find out how to best care for your Pink Princess Philodendron to avoid a sickly-looking plant.

Pink Princess Philodendron Overview

Did you know Pink Princess Philodendron makes one of the most expensive houseplants on Earth?

You will fail to find this pan-tropical plant in its natural setting because the plant is entirely lab-grown from tissue culture.

Moreover, every other Pink Princess in circulation comes from either laboratory or propagation.

The highly ornamental houseplant is solely grown for its royal variegated pink leaves, hence the name ‘Pink Princess.’

1. Indirect Sunlight and Warm Location

Pink Princess Philodendron thrives in bright, diffused sunlight to maintain rich variegation.

Provide your Pink Princess Philodendron with at least 6-8 hours of indirect sunlight every day by placing it next to a well-lit window, door, or patio.

The optimal light it receives, the higher chances of getting sharp foliage and optimal growth. However, keep them out of direct sunlight to prevent leaf burns and wilting.

Plant placed near the window where it gets enough sunlight
Plant placed near the window where it gets enough sunlight

Getting the proper lighting condition is essential for all kinds of Philodendron, which most growers are unaware of.

Exposure to excessive light will scorch the leaves, leading to curled tips, yellowing foliage, crispy texture, and slowed growth.

On the other hand, low light will devoid it of chlorophyll responsible for giving the plants its rich green color.

The variegated Pink Princess would require more light than the non-variegated kind to maintain green pigments for photosynthesis.

How to Treat Sun Exposed Plant?

Before administering treatment, begin with diagnosing the plant for over-exposed and under-exposed symptoms.

One way to tell your plant is not receiving enough sunlight is leggy growth with more petite foliage.

Other signs of light stressed plant include:

  • Dull and stunted growth
  • Yellowing of leaves
  • Loss of green pigments from the leaves
  • Dropping and limping leaves

On the other hand, direct sunlight will lead to transpiration (loss of water from the leaves) and sickly plants indicated by these signs.

  • Dry and crispy leaves
  • Brown patches along the leaf edges
  • Loss of color and variegation from the leaves
  • Curled leaves

Solutions
  • Bring your plant inside or move it away from windows to prevent direct sunlight. Wait until the leaves revive.
  • For overexposed plants, schedule watering every 7-days or twice every week with half amount of water.
  • Mist the plant to increase humidity and boost moisture inside the leaves.
  • Bring it close to the bright window or place it under an appropriate LED grow light for an underexposed plant.

Tips to Ensure Optimal Sunlight and Location

  • Place your Pink Princess Philodendron in the east or west-facing window that receives ample sun each day and some soft direct sunlight.
  • Ensure to place them 5-6 feet away from the light source when kept at the south-facing window to prevent leaf burn.
  • When growing outdoors, place your plant in the North-facing wall that protects it from the harsh sun throughout the day.
  • When kept indoors, ensure to avoid dark places devoid of sunlight.
  • Alternatively, you can grow them under the appropriate grow light, LED Full Spectrum, or MARS Hydro TS 1000W.

Pro Tip: Use a full-spectrum lamp with full Color Rendering Index that mimics the natural sunlight setting for better growth and foliage development.

2. Weekly Watering

Pink Princess Philodendron will require regular watering like any other Philodendron subspecies. It thrives in soil that stays consistently moist.

Water your Pink Princess Philodendron when the top 2-inches of the soil or 75% of topsoil dries out.

Schedule watering every 7-10 days in the growing season (spring and summer), which allows the plant to retain enough moisture without completely drying out.

Watering the plant
Watering the plant (Source: Tenor)

As per the rule, provide 800-900ml of water to a 5″pot every 7-10 days to your Pink Princess Philodendron.

However, cut back in fall and winter and water only once every 2-weeks or 20 days as it goes into dormancy.

Excess watering may lead to the waterlogging problem with plant roots sitting on the water, which not only drowns the roots but also promotes the decay process, leading to root rot.

On the other hand, underwatering or drought conditions will suck the plant dry due to excess transpiration (loss of water from the leaves).

The Philodendron can withstand all kinds of abuses, but it would not stand improper watering practices.

Overwatered or Underwatered Pink PrincessPhilodendron

The visible signs of an over or under-watered plant include the following,

Overwatered SignsUnder-watered Signs
Dark-colored soilLight greyish soil
Browning or darkening leavesYellowed leaves with a crispy texture
Lower stem decayWilted or curled leaves
Smelly potting mediumHard to touch stems
Solutions
  • For overwatered plants, cut back on watering and assess for root rot condition. Remove limp, dark, and mushy roots.
  • Wait until the leaves revive before watering again.
  • Consider deep watering or controlled water treatment for underwatered plants by submerging the container in a water-filled tub.

Tips to Ensure Adequate Watering

  • Check whether the top few inches of soil have dried out between watering.
  • Use a soil moisture meter to assess the soil condition; anything around four is appropriate.
  • Thoroughly water the pot, slowly pouring water on the soil without touching the foliage. Empty the saucer pan immediately.
  • Regular mist the plant leaves each week in summer or when the temperature soars above 95°F to prevent transpiration.
  • Alternatively, water the plant every time the soil moisture meter reads below 4.
  • Use tepid or chlorine-free water by leaving regular water open for 24-hours before using.

Pro Tip: Download a water scheduling app to keep a tab on watering your Pink Princess Philodendron.

3. Warm Temperature and High Humidity

Philodendron Pink Princess prefers temperature on the warmer side. Being a pan-tropical plant, it thrives in warm, humid conditions.

Pink Princess Philodendron does well in an ideal temperature range between 65°F to 79°F (18-27°C) during the day and around 60°F at night with 65-75% humidity.

Any average temperature in the USDA zones 9a, 9b, 10a, 10b, 11a, and 11b will be appropriate for Pink Princess Philodendron.

However, the plant is not cold-hardy, making it vulnerable to temperatures below 55°F, especially in fall and winter.

Prolonged exposure to cool temperatures will push back foliage growth and damage the pink variegation.

Similarly, it does well in moderately high humid conditions to ensure healthy-looking leaves, where low humidity can dry the plant leaves due to transpiration.

However, attaining a high humidity level in normal house conditions will be impossible, and excess humidity can push the plant towards fungal and bacterial growth.

Therefore, you should keep an eye out for inappropriate humidity levels.

Too Low HumidityToo High Humidity
Wilting and shriveled LeafStems and leaves rot
Yellowing of leaves edgesPatches of grey mould on the leaves
Brown leaf tipsFungal growth
Leaves may fall in severe conditionsMold presence in the soil and flower as well.

The risk of low humidity is higher in Philodendron plants which is often indicated by browning leaf edge, followed by loss of pink variegation.

Tips to Maintain Ideal Temperature

  • Pink Princess thrives in an ideal spot with ample indirect sunlight around the house, usually over 6 hours.
  • Otherwise, keep your plant under appropriate grow light, usually in fall and winter or when temperature dwindles, to compensate for low temperature.
  • Protect your plant by covering it with a frost blanket or clear plastic bag to prevent cold stress in winter.
  • Move the outdoor plant inside when the temperature begins dropping below 50°F.

Note: Beware about keeping them near the air conditioner or heater to prevent an utterly dry plant due to transpiration.

Tips to Maintain Ideal Humidity Level

  • If you all have a lot of houseplants, consider huddling them together to boost the local humidity level.
  • Otherwise, install an artificial room humidifier to maintain an ideal humid condition.
  • Mist the leaves a couple of times every week throughout the summer or when the temperature soars above 95°F using the plant mister.
  • Placing the plant on a pebble tray filled with water would be an ideal home solution to notch up the humidity level by 30-40%.
  • Alternatively, you should grow the plant near the bathroom or kitchen, the most humid place in the house.

Pro Tip: Use a hygrometer to check whether the humidity level drops or rises to a dangerous level.

4. Well-Drained, Organic Soil Mix

Philodendron Pink Princess prefers loose, well-draining soil rich in organic matter without becoming soggy.

The organic matter present in the soil will quickly drain out excess water while retaining healthy microbes.

Buy an aroid potting mix or prepare a homemade soil mix by mixing a significant amount of peat moss/coco coir and orchid bark mixed with perlite and worm casting.

In fact, the plant thrives on the humus-rich forest soil that is perfectly well-draining, which you can easily replicate at home.

The perlite and orchid bark adds chunky texture to the mix, allowing for good aeration, while worm casting boasts a healthy supply of microbes.

Similarly, the rich organic combination naturally provides an acidic (5.5-6.0) level to the soil.

How to Prepare an Ideal Pink Princess Potting Mix?

Here is a homemade recipe for preparing an ideal Pink Princess potting mix.

Voila, your Pink Princess Philodendron soil is ready!

Otherwise, you can always consider buying an ideal commercial potting mix from Amazon.

5. Monthly Fertilization

Pink Princess Philodendron enjoys regular fertilization in the growing season, which helps with boosted foliage growth.

Although it does well without fertilization, regular feeding will help get much-needed macronutrients.

Fertilize Pink Princess Philodendron every 3-4 weeks or once a month in the spring and summer with balanced liquid fertilizer.

Philodendron Fertilizer

Otherwise, you can apply slow-release granular fertilizer every 2-3 months.

Moreover, cut back on fertilization in dormancy (fall and winter) to prevent damage from fertilizer salts.

A nutrient deficient Pink Princess Philodendron is often indicated by slowed young leaf growth and smaller leaves.

On the other hand, excess fertilization can stunt plant growth and invite leaf browning and wilting. The excess salt build-up in the soil will kill healthy soil microbes and choke the roots of nutrients.

How to Revive Overfertilized Pink Princess Philodendron?

  • Thoroughly water the plant to flush out excess salts from the soil. Repeat the process 2-3 times.
  • Cut back on fertilization until the plant seems to recover.
  • Otherwise, transplant it to a fresh potting mix if the soil seems completely degraded, dry, and crumbled.

Tips to Apply Fertilizer Correctly

  • Always use a balanced plant food with an NPK ratio of 20-20-20 or 10-10-10.
  • Dilute the liquid solution to half strength by mixing it with water (1:1).
  • Always apply liquid fertilizer while watering the plant to allow the plant roots to get as many nutrients as possible.
  • Keep the solution at least 5-6 inches away from the plant’s base to prevent root burn.
  • Spread granular plant food around the plant and water thoroughly afterward.

Here are a few recommendations for a balanced fertilizer.

Note: A high Nitrogen content will lead to fast growth, but the plant will be primarily dark green. Conversely, equal Phosphorous and Potassium content will equal parts of pink variegation.

6. Repotting Pink Princess Philodendron

Philodendron Pink Princess would only require repotting once every two years when the container gets overtly root-bound.

Otherwise, repot the plant when the potting mix loses its texture, such as a dark and moist appearance.

A rootbound Philodendron Pink Princess will exhibit signs, including light-colored and crumbled potting mix, slowed plant growth, and roots poking out of the drainage holes.

How to Repot Pink Princess Philodendron?

Step 1: Choose an Ideal Container

Although Philodendron can be grown in any container, it is best grown in Terracotta or clay pots.

Otherwise, choose a pot with multiple drainage holes to allow sufficient drainage. Ceramic and plastic pots would work fine.

Moreover, choose a pot at least 2-inches bigger than the current one.

Here are a few recommendations.

ContainerSpecification
Classic Planter, 8" (Plastic)They are durable and lightweight. The drainage holes lie at the bottom
LE TAUCI Ceramic Plant Pots (Ceramic)4+5+6 inch, Set of 3, Planters with holes in the bottom
Plastic Planter, HOMENOTE (Plastic)Comes in five different sizes 7/6/5.5/4.8/4.5 Inch
Step 2: Remove the Plant
  • Consider repotting the plant in spring or summer when the risk of cold stress is at a minimum.
  • Turn the pot sideways and gently hold the stems. Next, tap the bottom to let the plant slides out.
  • Gently massage the roots to loosen the compact soil or wash it with clean water.
  • Inspect for signs of root rot, and do not forget to trim them away using a sterilized pruning shear.
  • Apply some fungicides on the cut ends to prevent fungal growth.

Step 3: Transplant the Plant
  • Ensure to layer the container bottom with crocks or small rocks before adding the potting mix.
  • Pour a layer of aroid potting mix into the new pot to 2/3 level.
  • Slide the plant inside the mix with roots facing down and fill it with the remaining potting mix.
  • Ensure the bottom leaves are an inch or more above the soil.
  • Do not forget to thoroughly water the soil before placing it back in its original location.

Pro Tip: Do not increase the pot size by greater than 2 inches, as adding more soil will take longer to dry out.

Growth Rate, Variegated Leaves, and Pruning

Pink Princess Philodendron is known for rapid growth in spring and summer when it will grow by a few inches.

A healthy growing plant will, Pink Princess Philodendron will attain a height of 2-3 feet and a width of about 2-feet.

Similarly, the leaves can grow up to 8-inches in length and 5-inches wide.

However, you must ensure the growing condition is correct by mimicking the right tropical environment.

Do not confuse it with Pink Congo, which resembles Pink Princess Philodendron, which reverts to green after a year.

Variegated Leaves

Talking about the leaves, the variegated pink texture will only be present on plants with a trace of variegation, usually from the mother plant.

Do not be surprised if your Pink Princess Philodendron reverts to all green leaves. Not all variegation is the same. Some plants have more traces of pink than others.

Variegation is very rare, where your chance of one randomly producing variegation is about 1:100’000.

The epiphytic plant root boasts aerial roots that grow out of nodes and latches onto supporting structures.

Pruning Pink Princess Philodendron

  • The plant would only require pruning to remove damaged or yellowed leaves in the growing season.
  • You can also trim leggy growth to divert the nutrients to other parts of the plant.
  • Cut off all green leaves if you want to balance out variegation in each leaf.

Note: Ensure to cut the stem right above the node to encourage new, vigorous growth.

Propagating Pink Princess Philodendron

Propagating Pink Princess Philodendron is an excellent idea to multiply plants with rich pink variegations in the comfort of your home.

However, remember not all propagated plants will achieve the signature pink leaves.

Best Time for Propagation

  • Propagating Pink Princess is best done in spring or early summer when the plant is actively growing.
  • Choose anytime between March and May when the length of sunlight is significantly longer.
  • Avoid propagating in fall or winter when the chances of cold draft and transplant stress are significantly high.

Propagating via Stem Cutting

Pink Princess Philodendron is relatively propagated from stem cutting as the chances of getting pink variegation are significantly high.

Your option is to take a set of healthy cuttings with pink leaves and propagate them in a different medium.

1. Rooting in Potting Mix

Here is a guided approach to propagating stem cutting in a potting mix.

  • Prepare a small-sized container with peat moss and vermiculite.
  • Introduce small holes underneath the pot.
  • Moisten the potting mix with water.
  • Gently insert the cutting into the soil mix and cover the tray with clear plastic to lock in the moisture and humidity.
  • Next, place the cutting in a warm location with indirect sunlight and a temperature around 70°F (21°C).
  • The cutting should begin rooting within two weeks. Let it rest for a few more weeks before transplanting it.
  • You can transplant it to a larger pot with a potting mix containing peat moss, orchid bark, horticultural charcoal, perlite, and coco coir.

2. Rooting in Water

Propagating the stem cutting in a water medium is another effective way to root the cutting.

Also known as Hydroponics, you will skip solid mix for tepid water.

  • Fill the jar with distilled water and submerge the cutting.
  • Place the pot in a warm location with indirect sunlight.
  • Replace the water every 4-5 days or when it slightly becomes brownish.
  • Check for new roots after 2-3 weeks.
  • Once the feeder roots have grown at least one inch after a few weeks, you can transfer them to a potting mix.

PestsProblems
MealybugThey mostly infect root and foliage.

They suck the sap from the leaves, leaving them wilted and discolored.

AphidsAphids are cricket-like creatures with back legs that suck up saps from the plant leaves and stems.

When the infestation grows, your plant wilt and starts dying.
ThripsThrips are small, brown insects that mainly feed on leaves.

They mainly infect overwatered plants or those placed in damp locations.
ScalesScaly insects are tiny, waxy pests that infest on leaves.

Yellow or rust-colored spots will start developing on the leaves, and the sap will begin drying up.

Solutions

  • Start with dislodging eggs and larvae by spraying the plant using a water hose.
  • Using a bunt knife, scrape off scales and insects from the plant.
  • Pick the visible pests and drop them in a soapy water solution using fingers.
  • The organic solution includes rubbing all parts of the plant with horticultural oil or Neem oil.
  • Otherwise, apply pest repellants like Malathion solution or Pyrethrin spray to effectively remove all pests.

Preventive Measures

  • Placing yellow sticky straps around will trap the crawling insects before reaching the plant.
  • Consider washing the plant with a soapy water solution or Neem oil in spring and summer.
  • Rubbing 98% isopropyl alcohol once or twice in the growing season will help repel different pests.
  • Quarantine the newly brought plant for at least two weeks before introducing them to other plants
  • Grow repellants like basil and mint or sage and rosemary plants around the Philodendron.

  • Apply potent fungicides like Medallion (fludioxonil) and Prostar (flutolanil) that effectively treat all kinds of fungal diseases.
  • Agrimycin will effectively treat bacterial infections and leaf spots, while Dimethomorph and phosphorus acid will treat Phytophthora and Pythium diseases.
  • Alternatively, you can apply organic fungicides like mefenoxam and aluminum tris/Fosetyl-al to prevent chemical damage.

Preventive Measures

  • Start with installing an electric humidifier to provide the correct humidity level.
  • Quarantine the suspicious-looking plant by keeping it away from other plants.
  • Brown or hollow patches on the leaf indicate a leaf spot that needs immediate treatment.
  • Always keep your plant in a location with a warm temperature and sufficient indirect sunlight.

Pink Princess Philodendron vs. Pink Congo

Due to the massive popularity of Pink Princess Philodendron, many sellers started selling fake plants that resemble Pink Princess Philodendron.

Also known as Pink Congo, the tropical plant originates in Congo and boasts similar pink variegated leaves.

However, Pink Congo boasts whole pink leaves, unlike Pink Princess, which has mixed variegation.

Here are a few differences between the two to help you find out the fake.

Pink Princess PhilodendronPink Congo
Sharp edges with fewer points leavesPointer leaves
The variegation will differ on each leafPink leaves on top with green leaves at the bottom
The pink shade is distinctly separate from the greenFull pink shade on leaves
Large-sized leavesRelatively smaller leaf size

Moreover, the Pink Congo does not hold the variegation for a long time, it will begin reverting to green color after a year because the pink shade on the leaves obtained using Auxin stimulates ethylene production.

FAQ About Pink Princess Philodendron

What does Browning Variegation Indicate?

It may be unusual to find browning variegation in Pink Princess Philodendron, but some can appear once in a while.

The browning will appear when your plant is exposed to too much harsh sunlight. It would usually happen when the pink portion gets scorched from harsh lighting.

As a solution, move your plant away from the window to avoid harsh light and introduce shade with ample indirect sunlight.

Read more about solving brown spots on Philodendron leaves.

Why are the Pink Leaves Dying?

The pink variegated leaves may begin dying early than the green leaves.

It is mainly because the variegated leaves lack chlorophyll production, which helps produce food for the plant or photosynthesis.

Therefore, the pink leaves are less resilient to a longer lifespan and may begin wilting soon.

Will Green Leaves Revert to Pink?

The pink variegation will begin reverting to green or stop growing signature variegation. Although rare, it may occur once in a while.

All you need to do is prune most green leaves so that the plant will push out variegated growth.

If you are lucky, it will push out pink variegation.
