Resembling most houseplants, White Knight Philodendron enjoys medium to bright indirect sunlight. Intense light can cause sunburn, while low light in a long period makes its leaves fade and become leggy.


White Knight will be happy and healthy in a humid environment with relatively high humidity at about 60 – 70% as a tropical cultivar.

How to maintain a humid place for Philodendron? You can mist its foliages regularly, use a humidifier, or group the plant with other tropical cultivars.


A warm temperature at about 65-80˚F (18-26˚C) at day and a bit lower at night without going under 55˚F(12˚C) will be the best for Philodendron.

Common Problems With Philodendron White Knight

Yellow leaves


Overwatered or sunburn.


  • Discard all the serious yellow leaves.
  • Ensure that your plant is exposed to filtered or soft light only.
  • Check the pot’s drainage. If the water is slow-released because it lacks holes or the soil is no longer loose, you should repot the plant.
  • Set an appropriate watering schedule, and make sure you don’t hydrate the ground until its top layers get dried.

Drooping leaves




  • Daily mist the foliages until the plant gets back to normal.
  • Check the soil’s dryness regularly and maintain a watering routine.

Bacterial leaf spot


Leaves get wet for a long time.


  • If it happens to a small number of leaves, discard those leaves first to avoid spreading the disease.
  • Treat the plant with a slight fungicide accordingly.
  • Make sure you don’t water the foliage again when they are wet.
