A white knight philodendron can be tricky to find, and when you manage to acquire one, you will need to know how to take care of it.

Philodendrons form part of a plant group called aroids. Aroid plants from the Araceae family and include many house plants. The philodendron genus has more than 480 types. Within the philodendron group, there is an additional division based on the growth pattern. Philodendrons can be climbers or self-heading plants. A few plants look almost similar to the white night, but it is not hard to distinguish them from one another with a little more information.

Do I Have A Philodendron White Knight?

Three philodendrons have similar white and green variegated leaves. A quick guide below can help tell them apart. The tree that can be confused are:

  • Philodendron White Knight
  • Philodendron White Wizard
  • Philodendron White Princess

Here is how to tell them apart. The philodendron white knight has white variegated leaves, carried on purple or brown stems. The white knight is a climber and can grow to nine feet with proper care and support.

A philodendron white princess has white variegated leaves that are smaller and narrower than the white knight. The white knight leaves can grow up to one and a half feet in size. The white princess, by contrast, has a maximum leaf length of seven inches. The white princess has green stems and is a self-heading plant. The white princess can also grow to a height of 9 feet but does not climb. This size will only be reached in mature plants aged around ten years.

The white wizard philodendron has larger white patches on the leaves than either of the other two varieties mentioned here. In addition to the difference in leaf color, the stems are also green.

Is Philodendron White Knight Rare?

Philodendron white knight is a common plant that is readily available in its natural habitat. It has grown in popularity as a houseplant outside of its native South America, and demand exceeds supply.

Most plants available in stores are harvested from their natural tropical environment and exported internationally. Philodendron white knight is a slow-growing plant. This fact contributes to how rare the white knight is.

How To Care For Philodendron White Knight

A philodendron white knight does need special care, but they are not high-maintenance plants. By following a few care instructions, you can be rewarded with a beautiful plant that will grow for many years.

Watering Needs

The growth rate of philodendron white knight is directly related to water availability. Too little water means that the plant does not have access to enough nutrients. Overwatering a white knight can lead to root rot. The best way to avoid these two extremes is to water it correctly and consistently.

Soil for a white knight philodendron should stay only slightly moist between watering. Allow the grow medium to almost dry out before watering. Test the soil by inserting a wooden popsicle stick into the grow medium for an hour and then check the watermarks on the stick.

Soil that is still wet will change the color of the stick, and grow medium will cling to it. Damp soil will only slightly discolor the stick, and very little grow medium will adhere to the stick. Dry soil will not change color, and no grow medium will cling to the stick.

This simple test can ensure that philodendrons are watered only when the top one inch of soil is dry. It is far more accurate than watering to a schedule. This takes the guesswork out of watering needs.

Lighting Needs

Light quality and quantity affect the growth rate of the white knight philodendron and can cause it to revert to a plain dark-leafed philodendron. A white knight philodendron requires at least four to five hours of bright indirect light each day. If natural light is not adequate, artificial light will work as well.

Direct and harsh sunlight will burn the white part of the white knight philodendron leaves and needs to be avoided. With too little light, a white knight philodendron will revert to a uniform green color. Keep watching for clues that show when the plant requires more light or less light.

Temperature Needs

The ideal environment for a white knight philodendron needs to mimic the tropical rainforest canopies where they originate from. The perfect temperature range is between 65°F and 80°F by day and a slightly lower temperature by night. The lowest temperature a white knight philodendron can tolerate is 55°F.

Failing to avoid lower temperatures slows the growth and makes the white color revert to dark green. Avoid placing white knight philodendrons in a space where they are exposed to drafts. Drafts can cause temperature fluctuations outside the ideal range for this plant. If a heater is needed to heat a room to keep it in the perfect temperature range, ensure that it does not dry out the air too much. (See humidity information below.)

What Is The Best Soil Type?

For a white knight philodendron to thrive, it needs soil that can retain some moisture but must also drain well. An ideal soil for a white knight plant will contain a high level of organic matter. Materials such as peat moss, coco coir, and orchid bark increase the organic content. Perlite and pumice allow good drainage. Other additions to an ideal soil mixture are items like worm castings, vermiculite, and activates charcoal.

Is Humidity Important?

Philodendron white knight originates from a tropical region. Therefore white knight loves an environment with high humidity. Without enough humidity, a white knight plant does not thrive. It can look droopy, and the leaves may discolor. A hygrometer will assist with checking humidity in the space where a white knight is growing. An ideal humidity range is between 55 and 70 percent.

If the humidity is too low naturally, a few things can help to correct this. A white knight will grow well in a humid room like a bathroom, provided it has enough light.

Keeping several tropical plants together in a room increases the humidity through a process called transpiration.

A humidifier is an excellent option to increase humidity if the air is too dry, especially if a heater is being used to correct temperature.

Mist plants with a very fine mist spray.

How To Fertilize A White Knight Philodendron.

It is essential to fertilize indoor plants frequently, as they do not have access to organic matter like outdoor plants do. There are a various options available. Some prefer to fertilize according to a schedule, say once for each season of the year. Some recommend a slow-release granular feed, while others suggest a liquid fertilizer. Each type has merit, and the approach should be adjusted according to plant needs.

To avoid dips and spikes in the nutrients, a white knight philodendron has access to; another alternative is to add nutrients to the water each time the plant is watered. Doing this copies the natural environment a lot more closely. As this method provides nutrients on an ongoing basis, the concentration of the solution can be a little lower than with a quarterly feed.

Liquid fertilizer works well when applying nutrients in each watering. Look for a natural fertilizer with a good balance of the three macronutrients, namely, nitrogen (for lush, healthy leaves), potassium (for a strong root structure), and phosphorus (to convert energy into new plant cells)

Also, ensure that the fertilizer contains a good supply of micronutrients, such as zinc (Zn), copper (Cu), iron (Fe), boron (B), manganese (Mn), molybdenum (Mo), and chlorine (Cl). Micronutrients help to prevent plant discoloration and stunted growth.

When feeding a philodendron with each watering, a weaker solution than the product recommendation should be used. A rough guideline is to use a quarter of the recommended dosage in the water each time.

Conclusion

Philodendron white knight is a beautiful addition to your indoor plant collection. Prepare the new environment for a white knight correctly, and it will remain a stunning addition to that space for many years.
