About Philodendron White Knight
The Philodendron White Knight is a one-of-a-kind tropical plant that’s got this awesome variegated look. It’s part of the Araceae family, and is a proud member of the Philodendron gang. It was born and raised in the South American rainforests.
The White Knight has got these oval green, white, and purple leaves and is famous for its lush greenery with white splotches and streaks all over. This South American kid is a great choice for indoor gardening but can also kick it outside if the weather’s not too chilly.
A White Knight Philodendron can shoot up to 3 metres high when it’s all grown up, and a leaf can get up to 1.5 feet long.
The size this plant can reach is all down to where it’s growing and what the conditions are like. In a wide-open space, a grown-up Philodendron White Knight can stretch out to about three metres long.

Caring for a Philodendron White Knight
The Philodendron White Knight is a real stunner that’s actually pretty chill to take care of. Here’s how you can keep your White Knight in tip-top shape:
The Philodendron White Knight, with its distinctive leaf pattern, has got some specific likes and dislikes when it comes to sunlight. How much light it gets, and what kind of light, can make a big difference to its growth, its leaf pattern, and its overall well-being.
These tropical beauties are fans of gentle, indirect sunlight. What you’re aiming for is bright light that’s been softened up a bit, because White Knight’s variegated leaves are a bit more touchy about sun exposure than plain green leaves. Harsh direct sunlight, especially when it’s really strong, can do some serious sunburn to the leaves, particularly the white parts. This damage shows up as a kind of burn, and it can spread really quickly in the white areas, since they don’t have as much chlorophyll as the green parts to protect them.
Getting the right amount of sunlight is super important to keep the cool leaf pattern of the Philodendron White Knight looking its best. If it doesn’t get enough light, the plant might lose its variegation and go more green. On the flip side, too much direct sunlight can damage the white parts of the leaves, causing them to shrivel up and disappear in a hurry.
To make sure your Philodendron White Knight gets just the right amount of light, there’s a few tricks you can try. You could hang up blinds or sheer curtains on your windows to soften up the harsh direct sunlight. Or you could put the plant near a north-facing window or just out of the sun’s direct reach to get the right kind of gentle light.
If you’re struggling to find a good spot in your house, or during the darker months, artificial grow lights can be a lifesaver. They can provide the bright, indirect light that the White Knight needs to really thrive. Adjustable grow lights let you control how bright the light is and how long the plant’s exposed to it, so you can mimic the kind of light conditions the plant would get in its natural tropical home.
The White Knight Philodendron, like its plant cousins, has a certain way it likes to be watered. You’ve got to hit that sweet spot where it’s getting the right amount of moisture, but not so much that you’re drowning it. The type of soil and how much water you give it are super important to keep it healthy, because if you mess up in these areas, you could end up with root rot. This nasty condition stops the plant from being able to take up the nutrients and water it needs, which can lead to a bunch of other problems like bugs, fungal diseases, and in the worst-case scenario, it could even kill the plant. If the leaves are starting to go yellow and wilt, you might be giving it too much water.
To keep your White Knight Philodendron happy, you’ve got to understand that how much water it needs can change depending on how much sun it gets, temperature changes, and the time of year. When it’s warmer in spring and summer, watering it once a week is usually just right. As it starts to cool down in fall and winter, cut back on the water to about once every 10 to 14 days. These are just guidelines, though, because it’ll also depend on your specific situation, so you’ll need to keep an eye on your plant.
This type of philodendron likes its soil to be moist but not soaking. To see if your plant needs a drink, check out the top two inches of soil. If it feels dry, it’s time to water. At the same time, if the leaves are drooping, it might be a sign the plant’s thirsty.
The type of soil and the drainage in the pot are just as important as how much you water. To stop overwatering, make sure your White Knight Philodendron is planted in soil that drains well and a pot with enough holes for the water to escape. After you’ve watered it, empty the saucers so the plant’s not sitting in stale water. If you can get all this right, your White Knight Philodendron will show off its awesome leaves in all their glory.
The Philodendron White Knight, a tropical leafy plant, loves a soil mix that’s airy, rich, moist, but also drains well. A big part of getting this plant to thrive is knowing and copying the conditions it would get in its natural home.
Start off with a base of good-quality potting soil. This type of soil has got all the nutrients and structure to help your plant grow strong and healthy. But just potting soil might not give the right amount of drainage and aeration that the Philodendron White Knight really needs.
To pump up the soil aeration and drainage, think about adding in things like orchid bark, perlite, and peat moss. Orchid bark and perlite both work to improve soil drainage, so you don’t end up with waterlogged soil. Better aeration means the plant’s roots can breathe, which stops root rot from lack of oxygen.
Philodendron White Knights like their soil to stay consistently moist without getting waterlogged. To hit this balance, add more organic stuff to your soil mix, like coco coir, coconut husk, or bits of mulch. These additions are great at holding onto water, and they can slowly release moisture to the plant roots.
You might want to try adding vermiculite to your soil mix. This mineral, when used with peat moss and perlite, can boost the soil’s ability to hold onto and drain water. But be careful not to go overboard, because too much water-holding can make the soil too damp, and the Philodendron White Knight isn’t into that.
Finally, make your soil mix even better by adding compost or mulch. These natural soil boosters not only make the soil more fertile, but they also help it hold onto moisture. They’ll help create a rich, nourishing environment that the Philodendron White Knight will absolutely love.
The Philodendron White Knight is all about the heat because it’s a tropical plant and really likes temperatures of 65 to 80 °F. If the temperature drops below 55°F or gets above 90°F, your White Knight plant won’t be happy.
You should avoid letting the temperature drop below 55 degrees Fahrenheit, because philodendron plants just don’t do well in those conditions. The Philodendron White Knight doesn’t get on with cold weather or frost.
This Philodendron is a bit sensitive to temperature changes and isn’t a fan of drafts. You’re better off keeping it in a room with stable temperatures and away from air conditioning vents, heaters, or open windows.
The Philodendron White Knight needs plenty of humidity to do its thing. The best humidity range for this plant is between 60% and 80%.
When humidity levels drop, the plant’s growth tends to slow down. Winter brings a drier atmosphere with less humidity and not much water vapor.
You can crank up the humidity by using a humidifier, placing a tray of water near the plant, or grouping the plant with others. You could even put your plant in the bathroom – but only if there’s enough light in there.
While you can spray the plant’s leaves with water, this isn’t really a reliable long-term solution.
Remember, this plant shouldn’t be placed near heaters, air conditioning vents, or open windows because it doesn’t like cold drafts or sudden temperature changes. The plant will do its best if you keep it in a place with consistent humidity and temperature.
In the growing season, which usually runs from spring to fall, you should feed your Philodendron White Knight with a balanced fertilizer once a month.
You can use a water-soluble fertilizer at half the strength recommended on the packet, with a 10-10-10 or 20-20-20 N-P-K.
Avoid overfeeding your plant because this can cause fertilizer burn and damage the roots. Throughout the growing season, you should feed your plant every two weeks and stop feeding it during the winter when it’s dormant.
Always make sure the soil is moist before feeding, and don’t feed plants that are sick, stressed, or have been recently moved. Always follow the instructions on the fertilizer packet, and adjust how often and how much you feed the plant based on how it’s responding.
When your Philodendron White Knight starts to get big, you’ll need to give it more room in a new pot to keep it healthy and growing. If you see that the roots are starting to take over the whole pot, it’s time for a change.
If you think your White Knight philodendron has got root rot, which can seriously hurt or even kill the plant, that’s another reason to change pots.
The best time for moving the plant is in the spring or early summer when the plant is in full-on growing mode.
To change pots, here’s what you do:
- Choose a pot that’s one size up from the current one and make sure it has drainage holes. Don’t go too big with the new pot because you could end up giving the plant too much water and causing root rot.
- Put some fresh, well-draining potting mix in the bottom of the new pot, leaving enough space for the plant’s root ball.
- Gently take the plant out of its current pot and loosen any tight roots.
- Put the plant in the new pot and fill in around it with fresh potting mix, leaving enough room at the top for watering.
- Water the plant really well and let any extra water drain out of the bottom of the pot.
- Put the plant somewhere with bright, indirect light, and keep it out of direct sunlight for a few days so it can get used to its new digs.
Remember to water the plant properly after moving it, as the new soil might dry out faster than the old soil. It’s a good idea to wait at least a week before feeding the plant after moving it so you don’t stress it out.
You’ll want to tidy up your White Knight if it’s showing signs of being sick or if it’s got brown leaves. Cleaning up a White Knight is pretty straightforward.
Here’s how you do it:
- Get your pruning shears or scissors super clean with rubbing alcohol or a disinfectant solution.
- Take off any yellow, brown, or damaged leaves, and get rid of any dead stems or branches.
- If any stems have gotten too long, cut them back, making sure to cut just above a leaf node.
Philodendron White Knight Propagation
You can easily make more White Knights from stem cuttings. The best time to get these cuttings is from spring through July.
Choose a healthy part of the plant for your cuttings, ideally new growth. Go for a stem with just two or three nodes.
Here’s how to make more of this awesome houseplant:
- Pick a healthy Philodendron White Knight and find a stem with a few leaves.
- Get your scissors super clean by soaking them in some alcohol.
- With a clean, sharp pair of scissors or pruning shears, cut a section of stem that’s about 4-6 inches long.
- Take off the bottom leaves from the stem cutting, but leave a few leaves at the top.
- Stick the stem cutting in a glass of clean water, making sure the aerial root is all the way in the water and the leaf is out of the water. Or you can put the stem cutting into a pot filled with well-draining potting soil, making sure the soil is damp but not too wet.
After about 1-3 weeks, roots should start to grow and new growth will show up on the top of the stem cutting of your White Knight.
Then, it can move into a bigger pot with regular potting soil.
White Knight Philodendron Common Pests
The most common pests that can cause trouble for your White Knight Philodendron include aphids, fungus gnats, and mealybugs. If you don’t deal with these little critters, they can really mess up your plant.
- Aphids: These tiny bugs have soft bodies and like to suck the sap out of the plant’s leaves and stems. They have long antennae and bodies that look like little pears. If you get a serious aphid problem, your plant could stop growing properly, its leaves could go yellow, and the foliage could get all distorted because these pests reproduce super fast.
- Fungus gnats: These are small, dark-colored flies that lay their eggs in the soil of indoor plants. The babies feed on stuff in the soil, including the plant’s roots. If you get a bad case of fungus gnats, your plant could start to wilt, its leaves could go yellow, and it might not grow properly.
- Mealybugs: These are tiny, white bugs that look like little bits of cotton. They like to hang out on plant stems and the undersides of leaves. They also suck the sap out of the plant, which can stunt its growth, turn its leaves yellow, and cause leaves to fall off.
How to get rid of them: You can use neem oil or insecticidal soap to get rid of aphids and mealybugs.
You can kill off fungus gnat babies quickly and effectively with hydrogen peroxide, which kills them on contact. Mix up a solution of four parts water to one part hydrogen peroxide and pour it onto the soil of your White Knight Philodendron.
If you want to stop a bug problem from getting worse, it’s best to keep an eye on your plant and do something as soon as you notice a problem.
White Knight Philodendron Plant Diseases
Here are some common problems that can give your plant a hard time:
- Leaf Spot: This is a problem that causes weird brown patches on the leaves. You can deal with it by getting rid of the dodgy leaves and using a fungicide.
- Root Rot: This is a fungus problem that can be caused by too much watering or bad drainage. It can make the leaves go yellow, cause wilting, and stop the plant from growing properly. To sort it out, improve your drainage and don’t water so much. You can also use a fungicide to deal with the problem.
- Bacterial Blight: This is a bacteria problem that can make the plant wilt and die. It causes brown or black spots on the leaves. You can manage this by getting rid of the affected leaves and using a bactericide.
To avoid these problems, make sure you’re looking after your White Knight Philodendron properly. This means giving it enough light, watering it the right way, and making sure there’s good air movement. You also need to avoid overcrowding and keep things clean by getting rid of dead leaves and other junk from the top of the soil. Regularly checking your plant for signs of disease will help you spot any problems early and stop them from spreading to other parts of the plant.
