1. Proper Sunlight and Warm Location
Philodendron Plowmanii is native to tropical rain forests; they are often found thriving under the cover of big trees.
Therefore, trying to mimic a similar lighting condition would be ideal for your plant to thrive.
Philodendron Plowmanii is a low to moderate light-loving plant that thrives well in bright indirect sunlit places for at least 4 to 6 hours daily.
Meanwhile, the Plowmanii Philodendron are seemingly fine in low-light environments as well.
The morning sun won’t hurt your plant but instead promotes large, waxy foliage.
On the other hand, they shall not be placed where the direct sunlight falls upon them to avoid sunburn or scorching.
It is best to set back from a window to ensure that the sun doesn’t directly touch the foliage.
Do you know your Philodendron Plowmanii can survive no light for like 12 to 20 days before dying of chlorosis?
Here are a few tale-tell signs your Philodendron Plowmanii may exhibit under low or excess sunlight.
|Lack of Sunlight||Extreme Sunlight|
|Sparse or leggy growth||Browning leaves and tips|
|Plant leaning towards the light source||Limp and dehydrated plant|
|Small leaves||Parched and cracked soil|
|No or stunted growth||Scorched leaves|
Tips to Maintain Adequate Light for Philodendron Plowmanii
- Try placing your plant in an east-facing window to get ample early morning sun.
- Place them in a south-facing window; however, ensure to place them at least 5 feet away to avoid sunburn.
- Ensure to use drapes or curtains to drop the light intensity.
- If you are keeping your plant outdoors, ensure to provide them with partial shade and dappled sunlight.
- Ensure to rotate your plant once in a while to facilitate uniform light distribution.
- Use a light meter to find the most optimal place with the best light intensity suitable for your plant.
- Use full-spectrum grow lamps with 10,000 to 20,000 lux and at least ten hours if your plant shows light deprivation symptoms.

2. Regular Watering
Native to rainforest vegetation, Philodendron Plowmanii is a moisture-loving plant. It is critical to water them regularly.
Generally, Philodendron Plowmanii requires watering two times a week during active growth and once a week during winter.
You can follow the general rule of thumb and water your plant once the first few inches of soil dry out.
When winter kicks in, reduce the watering frequency to allow your plant to rest during its dormancy.
Not allowing the top of the soil to dry out between waterings can lead to root rot, eventually destroying your plant.
Moreover, your plant’s water needs vary depending on the climate and season.
If your plant is showcasing the following signs, understand your plant is getting improper watering.
|Overwatered Signs||Under-watered Signs|
|Dark-colored soil||Light greyish soil|
|Browning or darkening leaves||Yellowed leaves|
|Lower stem decay and root rot||Wilted or curled leaves|
|Smelly potting medium||Stunted growth|
Solutions for Underwatered and Overwatered Plant
- Consider deep soaking your underwatered Philodendron Plowmanii by submerging them in a pot half filled with soil mix.
- Keep watering the plant unless you see the water running through the drainage holes.
- Reduce watering of your overwatered Philodendron Plowmanii plant immediately and investigate soil quality and potential root rots.
- Place your plant in a drier place with a slightly warmer place, and repot your plant if the soil looks drenched.
- Trim off all dark, mushy, and rotted roots and apply fungicides to them before proceeding to the repotting.
Tips for Watering Philodendron Plowmanii
- Do not stick to a hard and fast watering schedule. Instead, hydrate your plant when the top 2-3 inches of soil feels dry.
- Alternatively, get a soil moisture meter and water when the reading falls below three or is in the dry zone.
- Use clean filtered water, rainwater, or distilled water to water the plant.
- You can also use tap water; however, let the tap water sit for 24 hours before use.
- Water your plant during morning hours and follow the top watering approach. Or apply the bottom watering technique to encourage better root growth.
- Do not water your plant with too hot or too cold water. Normal room temperate water will work best for your plant.
Pro Tip: Use chopsticks and shove them into the soil. If the first few inches of soil are dry, it is time to water your plant.
3. Warm Temperature
Philodendron Plowmanii is sensitive to cold and prefers warmer temperatures.
Philodendron Plowmanii prefers temperatures between 60 and 85° F (15 and 30° C) and dislikes cold frosty months, making it difficult to grow them outdoors in frosty climates.
Thus, growing Philodendron Plowmanii would be ideal in USDA zones 9 to 11.
If the temperature falls below 55°F (~12.8°C), the foliage may develop dark brown/black patches caused by cold shock.
Moreover, extensive exposure to cold temperatures suppresses the growth of foliage and may ultimately lead to death.
In contrast to coldness, exposure to very high temperatures increases transpiration, leading to extreme dehydration.
Tips to Maintain Ideal Temperature
- Avoid placing your plant near the heat radiators, air conditioning vents, drafty windowsill, or electric fans.
- Ensure to keep your plant out of reach from direct sunlight to avoid sunburns.
- Try arranging a greenhouse with artificial heat regulation for your plant during its dormant period.
- Use frost blankets to cover the plant protecting it from frosts, and place heating pads underneath the plant pot to keep them warmer.
- Opt for using pine straws and dried grass on top of the soil to trap heat.
- If the temperature falls below 55°F, keep your plants indoors under LED grow light throughout the wintery months.
- Regularly mist your plant and increase the watering schedule when the summer kicks in to compensate for the heat.
4. Moderately Higher Humidity
To keep tropical plants, it is necessary to provide them with extra humidity.
Generally, Philodendron Plowmanii prefers high relative humidity (60% or more), but it can survive on average to significantly reduced levels.
Furthermore, it will be beneficial to keep your Philodendron Plowmanii at a relatively higher humidity level, similar to its natural habitat.
Meanwhile, it is not easy to maintain the higher humidity, but the latest technologies like a room humidifier can help you achieve it.
Remember, anything below or above the suggested humidity value can be detrimental.
Watch out for these tell-tale signs in your Philodendron Plowmanii.
|Too Low Humidity||Too High Humidity|
|Wilting, drooping and shriveled Leaf||Stems and leaves rot|
|Yellowing of leaves edges (chlorosis)||Patches of grey mold on the leaves|
|Brown leaf tips and leaf margins||Fungal growth and give rise to chances of fungal infections|
|Curled leaves may fall in severe conditions||May result in development of Xanthomonas bacteria infection|
Tips to Maintain High Humidity for Philodendron Plowmanii
- Invest in the electric humidifier to adjust the humidity level per the care requirements.
- Increase humidity by setting the plant in a deep pebble dish with water, ensuring the moisture does not touch the planter.
- Grouping plants is also an excellent way to boost humidity around the plant.
- Mist the plant occasionally during summer or when the temperature exceeds 90°F. However, clean the leaves after misting to avoid fungal growth.
- Use a hygrometer to measure the humidity level so your plant is getting and follow accordingly.
5. Light, Well-Draining Soilless Mix
As we all know, we bring home the Philodendron Plowmanii for its exotic bicolored heart-shaped leaves.

6. Bimonthly Fertilization
Regarding fertilizer needs, Philodendron Plowmanii does not require frequent fertilizing; they do quite well even without fertilization.
But if you want to speed up your plant’s growth even more, there’s nothing wrong with adding a little fertilizer periodically.
Generally, Philodendron Plowmanii prefers balanced 10-10-10 slow-release fertilizers every two months during its growing season.
But it is best to avoid fertilization during the winter to avoid over-fertilization issues.
Furthermore, you shall opt for Nitrogen rich fertilizers to promote exotic dual-colored foliage of Philodendron Plowmanii.
These exotic houseplants can also be fertilized with liquid fertilizers but ensure to avoid low-quality fertilizers.
Tip: Always dilute liquid fertilizers to their half strength before applying them so as to avoid fertilizer burn.
Although Philodendron Plowmanii thrives with little fertilizer, a deficiency in soil nutrients can make your plant lose its beauty.
In addition, inadequate fertilization results in stunted growth, fading foliage color, and yellowing leaves.
On the other hand, overfertilization may harm your plant through chemical burns and salt build-ups on the soil.
How to Treat Overfertilized Plant?
- Place your plant on the sink and run water on them while letting the water drain out from the drainage holes.
- Repeat the process three-four times to flush out the excessive nutrient build-ups completely.
- Do not fertilize your plant until it returns to its original healthy state.
- If your plant pot does not have proper drainage, consider repotting your plant to a new potting mix after running the plant roots on lukewarm water for a while.
- Use homemade organic fertilizers to avoid the risk of chemical burns and salt build-ups.
Here are some commercial fertilizers for your Philodendron Plowmanii.
- Philodendron Fertilizer
- Espoma Organic Indoor Plant Food
- Osmocote Smart-Release Plant Food

Pro Tip: When using slow-release fertilizers, ensure to apply fertilizers at least 6 inches away from the plant base to avoid any chemical burns.
7. Growth Rate, Foliage, and Flowering
Do you know the leaf color of Philodendron Plowmanii differs depending upon the environmental factors?
Philodendron Plowmanii is a creeping evergreen plant with a slow-paced growing habit.
When given optimal growing conditions, a mature Philodendron Plowmanii will reach a height of eight feet and a width of nearly two feet.
The active growing time for Philodendron Plowmanii is spring and summer, whereas dormancy is in winter.
Although most Philodendrons are climbers, your Plowmanii is not one of them. Instead, it is a creeping plant.
The color combination of varying glossy green gradients on leaves along the creamy-colored veins is truly an alluring beauty that everyone adores.
Furthermore, younger Philodendron Plowmanii tends to have silvery streaks on its round leaves.
This exotic plant with velvety leaves strictly grows on the ground and also can grow as a hemiepiphyte in rare cases.
They have a sub-leathery surface and a slightly shiny upper portion. The lower side is lighter in color and has a matte finish.
Philodendron Plowmanii’s multicolored petiole with rippling winged borders towards the apex, is its one of the most interesting features.
Moreover, the Philodendron Plowmanii’s stem acts as a base rather than supporting the giant leaves.
Your Philodendron Plowmanii won’t leave your side for many years if you keep showering love and affection on it.
Philodendrons are very unlikely to bloom when kept as indoor houseplants, so you rarely see them bloom.
Furthermore, Philodendron Plowmanii produces a bloom after reaching maturity (usually 10-15 years) with an inflorescence.
Generally, it produces three simple white to yellow spathes per axil on a reddish-tinged peduncle.
These inflorescences are unscented, meaning they have no smell or odor.
Although they might bloom in the spring in the wild, it is very unlikely for your Plowmanii to bloom indoors.
Do you know Philodendrons are thermogenic plants that produce heat by burning fats to attract pollinators?
After the successful pollination, Plowmanii flower spathe turns into fruit. When the fruit is mature, you can extract seeds from it.
Generally, the seeds are globular or ellipsoidal, which you can harvest from the fruit during late summer.
You can use these Philodendron seeds and propagate your Plowmanii.
8. Potting and Repotting
Philodendron Plowmanii prefers to stay in a pot with its roots free rather than rootbound.
To keep your Philodendron Plowmanii happy and healthy, repot it annually in a slightly larger pot than the previous one.
The ideal time for repotting your Philodendron Plowmanii would be spring or summer.
Repotting your plant once a year refreshes the soil, providing better nutrient sources and aeration for the plant while growing.
Meanwhile, it despises being tethered to the ground and requires abundant space to fit its enormous size.
Therefore, when the roots are not overly crowded, Plowmanii becomes tall and healthy.
To encourage healthy growth, transplant your Plowmanii in the following cases.
- Your plant has been severely affected by a deadly illness.
- Roots are poking out from the pot’s drainage holes or are about to escape from the topsoil.
- The plant has become big and bulky, requiring support to hold its posture.
- No new foliage development or stunted growth.
- Potting soil has become tight and compact discouraging proper drainage and air circulation.
- Overfertilization situation with excessive salt build-ups in the soil.
Steps to Repot Philodendron Plowmanii
Let’s take a look at a step-by-step guide.
Step 1: Choose an Ideal Container
Clay or terracotta pots work best Philodendron Plowmanii.
However, you can use plastic pots with multiple drainage holes to facilitate proper drainage.
Here are a few recommendations.
|LE TAUCI Ceramic Plant Pots||4+5+6 inch, Set of 3, Planters with holes in the bottom.|
|Classic Planter, 8" (Plastic)||They are durable and lightweight. The drainage holes lie at the bottom.|
|Plastic Planter, HOMENOTE (Plastic)||Comes in five different sizes 7/6/5.5/4.8/4.5 Inch.|
Step 2: Choose Soil Mix and Transplant
- Prepare or select the ideal soil mix for your Philodendron Plowmanii as instructed above.
- Carefully extract the plant from its existing pot or planter.
- Inspect the roots for diseases and trim away any damaged or diseased roots.
- Gradually loosen the roots of the plant with your fingertips. You can prune any extra-long threadlike roots away.
- Fill the empty container with fresh potting soil and place the plant inside with roots facing down.
- Fill up the remaining portion of the pot with soil mix but leave about a few inches of space at the top.
- Water your plant thoroughly and let it rest in its previous thriving position.
Remember, a newly repotted Philodendron Plowmanii does not require fertilization.
9. Occasional Pruning
Philodendron Plowmanii is a low-maintenance plant that does not require pruning regularly.
However, pruning off old, decayed growth or dead leaves regularly would ensure a clean and healthy Philodendron Plowmanii plant.
Ensure to remove dead, yellow, or damaged foliage. Remember that excessive pruning can slow the plant’s growth rate.
Additionally, pruning Philodendron Plowmanii at the beginning of autumn would benefit your plant for better growth.
Tips to Prune Philodendron Plowmanii
- Examine the plant’s structural stability and check whether it is getting lanky or has sick or decaying foliage.
- Employ pruning shears if the plant’s stems and branches are robust. Kitchen knives may provide you with a smoother cut.
- Remove all the damaged leaves and stems from the plant.
- Make appropriate incisions to foster new growth. Ensure to trim just before a node close to the main stem as feasible while trimming back larger stems.
- Do not trim off more than 25 percent of the plant simultaneously.
Toxicity of Philodendron Plowmanii
According to ASPCA, Philodendron Plowmanii is toxic to humans and pets, like other Philodendrons.
All parts of the Philodendron plant contain insoluble calcium oxalate crystals that make them toxic for pets.
Therefore, keep your dogs, cats, and kids away from the plant to avoid accidental ingestions.
Signs of Philodendron Plowmanii Toxicity in Pets
- Skin irritation
- Oral discomfort with swelling and blisters
- Loss of appetite
- Difficulty swallowing and breathing
- Scratching at the face or mouth
Pro Tip: Keep your pets away from plants by using pet repellant sprays.

Propagating Philodendron Plowmanii
Philodendron Plowmanii is more expensive than other houseplants and is difficult to find. As a result, propagating Philodendron Plowmanii would be an excellent method of populating them.
Moreover, there are two different techniques to propagate your plant. They are via stem cuttings and the air layering method.
But, many plant owners or gardeners prefer stem cuttings as it is easier to yield results faster.
The ideal time to propagate Philodendron Plowmanii is during spring or summer.
Some gardeners and plant owners follow seed propagation despite its staggering lengthy and delicate process.
Materials Required for Propagation
Before getting your hands dirty, ensure to get these items needed for propagation.
|Gardening Knife||For stem cutting|
|Gardening Gloves||For safety|
|Potting Mix||Potting Medium|
|Perlite||For extra drainage|
|Rooting Hormone||For best growth|
|Terracotta Pot with a Drainage Hole||Well draining organic pottig mix|
|Humidifier||To maintain the humidity|
1. Propagating via Stem Cutting
The propagation of Philodendron Plowmanii via stem cutting can be carried out in soil or water medium.
Before starting the propagation process, wear protective gear such as gloves and glasses to avoid accidental allergies.
Here is a complete step-by-side guide for propagating via stem cutting.
Step 1: Cut the Stem
- Disinfect a pair of scissors or small pruning shears with rubbing alcohol.
- Select a stem with several leaves and nodes.
- Ensure to cut the stem at least 4-inches long.
- Try to cut the stem clean at a 45° angle to increase the surface area of the exposed node.
- Leave it aside and let the cut end produce callous, which helps with regrowth.
Step 2: Choose Soil or Water Medium
Here are the proper detailed steps to propagate via each medium.
For Water Propagation
- Get a clean jar and fill it with clean, tepid water leaving about one-inch space at the rim.
- A few hours prior, let the water sit, then place the stem cutting.
- Add a few drops of rooting hormones to encourage healthier root sprouts.
- Position the stem cutting in a jar of lukewarm water (too hot or too cold may damage the cutting).
- Ensure to immerse the bare nodes fully in the water.
- Set the jar in a warm location with plenty of indirect sunlight.
- Keep changing the water every 2-4 days to refresh the plant and prevent bacteria from building up.
- It takes 2-3 weeks or the cutting to grow roots.
- Once the roots are 1-2 inches long, remove them from the water and plant them in a high-quality potting mix.
- Resume with the regular Philodendron Plowmanii care.
For Soil Propagation
- Prepare a starter potting mix using perlite, peat moss, and orchid barks in a 2-3 inches pot.
- Place the cutting in starter soil while leaving out the leaves.
- For faster root development, add rooting hormone powder into the mix.
- Water frequently enough to keep the soil moist, and water immediately if it dries.
- The optimal temperature for stem cutting to encourage growth is about 70 to 75°F.
- Cover your stem cuttings with clear plastics to mimic a mini greenhouse for humidity.
- Delicately pull the plant and feel the resistance it delivers to see if the roots have begun to grow.
- When you notice that strong roots have formed, it usually takes 3 to 4 weeks. After that, transfer the plant to its designated planter or pot.
2. Propagation Via Air Layering
Air layering, also known as marcotting, is a popular technique of propagation used for rare and valuable plants or subtle cultivars.
This technique minimizes the loss of lower leaves common in fresh cuttings that are actively growing roots.
To air layer your Philodendron Plowmanii, follow these instructions:
- Select a healthy part of the plant with at least two nodes for efficient propagation.
- Cover the nodes with the help of sphagnum peat moss or coco coir. Be generous while covering the nodes.
- To keep the peat moss or coir intact with the nodes, use a cling wrap to ensure it is stable and won’t fall apart.
- Mist the moss or coir to keep it moist throughout the whole time.
- You can use a chopstick and make holes in the cling wrap to encourage proper air circulation inside the wrapper.
- Aerial roots shall appear or sprout within 3-5 weeks, so wait till then while ensuring proper care of the plant.
- Once you notice aerial roots developing on the peat moss or coir, proceed to transplant by removing the cling wrap.
- Remove the propagated portion from the mother plant and plant it in the ground.
Common Problems in Philodendron Plowmanii
Although Philodendron species are not very prone to pests and diseases, they can sometimes confront pests or horticultural issues.
Here are the common problems that your Philodendron Plowmanii may suffer from.
1. Common Plant Pests
Generally, when a plant is provided with higher humidity and moisture content, some common sworn enemies of houseplants attack the plant.
Some of those plant pests that you shall need to be aware of are aphids, spider mites, scales, and mealybugs.
These small yet very harmful creatures cause severe problems and may even cause untimely death when left untreated on time.
|Aphids||1. Curling and falling off leaves
2. Stunted growth
|Spider Mites||1. Webbings develop underside of leaves or at leaf axils
2. Feast on plant's fluid resulting in drooping and wilting of leaves
|Mealy bugs||1. Responsible for sooty molds
2. White cotton like substance on underside of leaves
3. Stunted growth
|Scales||1. They suck the juice out of plants causing deformed leaves, brown pock marks
2. Sudden wilting and discoloration of foliages
|Thrips||1. Causes discoloration, premature dying of flowers and buds
2. Feasts on leaves causing them to shed and stunting or dwarfing.
- Immediately prune off heavily infected parts of the plants.
- Apply insecticidal soap or neem oil by spraying them on plants as an organic solution.
- Wash your infected plant with the help of a water hose to remove underlying pests, larvae, and eggs.
- Apply alcohol or dish soap using a cotton ball to kill pests.
- Use a horticultural oil or isopropyl alcohol to remove pests and their eggs.
- Handpick observable pests and throw them in soapy water. Remember to wear gloves to avoid any potential allergies.
- If nothing seems to be working, resort to Malathion solutions or Pyrethrin spray.

- Immediately isolate suspicious sick-looking plants to prevent further spreading.
- Regularly inspect your plants’ health and monitor the environmental parameters as a precaution.
- From time to time, cleaning your plant leaves with soapy water solution can do wonders during the growing seasons.
- Opt for using yellow sticky traps around the plant to capture pests.
- Be careful with your fertilizer as low-quality fertilizers invite different pests and soil toxicity problems.
Find out why your Philodendron Leaves are curling.
2. Horticultural Diseases
The Philodendrons are popular for their higher resistance to getting sick from diseases.
However, when they are not provided with proper care, your Philodendron Plowmanii is more prone to get infected with several diseases.
Generally, horticultural diseases are caused by excess humidity and waterlogged compact soil.
Here I have listed some of the common diseases observed in Philodendron Plowmanii.
|Root rot||Drooping and rapidly yellowing leaves, stunted growth and a rotten brown base is the primary sign of possible root rot.
Brown and mushy texture on the root is another sign.
|Erwinia blight||Appears yellow, pale, and less vigorous.
Shunted growth of the plant and usually affects plants that live in waterlogged soil.
|Pseudomonas leaf spot||Reddish brown spots on the leaf spots causing leaves and stem to appear fragmented.
Build watery, yellow lesions and begins to droop.
|Xanthomonas leaf spot (Bacterial Blight)||It is caused by the pathogen Xanthomonas campestris pv. Dieffenbachiae.
It forms transparent spots on leaf edges that develop brown with tan or yellow halos.
|Rust Spots||Tiny specks or spots on leaves that range in color from orange to rusty-brown, brownish-yellow, purple and red.
- Immediate quarantining of the plant to prevent further spreading of infection
- Take out the plant to investigate the condition of the roots and look out for healthy white roots.
- Thoroughly inspect the plant to grasp the severity of the problem and discard the plants if the condition is too severe and helpless.
- Trim the rotted roots to salvage the plant if any healthy roots are present.
- Before placing the plant in a new fresh potting mix, apply fungicides to the cut ends.
- Use Medallion(fludioxonil) and Prostar (flutolanil) to treat fungal diseases effectively.
- Apply fungicides containing Chlorothalonil and Mancozeb to control the spreading of rust spots.
Xanthomonas, Erwinia blight, and rust spots are hard to control via chemical applications, so it is best to adopt preventive measures before your plant gets infected with them.
- Try to keep your plant within the recommended level of humidity and temperature.
- Avoid high humidity for an extended period as they are favorable conditions for fungal diseases.
- Avoid misting leaves during the winter and in the evening.
- Apply copper, and sulfur powder enriched fungicides to keep the horticultural diseases at bay.
- Keep your plant in a bright warm sunlit place. Remember, direct sunlight is a big NO.
- Do not place suspicious sick looking plants in your plant collection.
3. Chlorosis Conundrum
Chlorosis Conundrum is a Magnesium deprivation condition that causes the V-shaped yellowing on leaves of the Philodendron plant.
Generally, Magnesium (Mg) is vital for plants to produce Chlorophyll, and a lack of Mg causes a drop in Chlorophyll.
Yellowing or color fading with the premature death of the leaves are the major symptoms of chlorosis.
Magnesium deficiency occurs if you readily use potash or fertilizer enriched with potassium.
To overcome this problem, add one tablespoon of magnesium sulfate or Epsom salts per gallon of water and thoroughly soak the soil with it.
But ensure leaves and stems are not getting splashed from salt water. Meanwhile, you can perform soil pH tests from time to time as Mg deficiency is often seen in alkaline soils.
Resemblance Philodendron Plowmanii to Other Similar Plants
Philodendron varieties share quite similar features like giant leaf shapes, flowers, and growing natures.
So, it’s no wonder people make mistakes while identifying them.
Let us find out the differences between other plants that may look like Philodendron Plowmanii, shall we?
Philodendron Plowmanii vs. Mamei
Philodendron Mamei is often mistaken for Plowmanii due to their identical striking resemblance.
But you can easily recognize them thanks to two additional distinctive characteristics that they have.
Firstly, Mamei leaves have silvery white variegation with closely spaced veins on their glossy leaves.
Meanwhile, Plowmanii has widely spaced veins with no variegation in its leaf.
Secondly, Plowmanii has unique fabric-like ruffly edge petioles, which are not present (or very small ones) in the Mamei plant.
Other than these two major differences, you can feel and observe the veins on the leaf of Plowmanii a bit more sunken than of Philodendron Mamei leaf.
Philodendron Plowmanii vs. Gloriosum
Another Philodendron species that is often falsely identified as Plowmanii is Philodendron Gloriosum.
