Caring tips for Philodendron Ilsemanii

Caring for Philodendrons is quite easy, but little knowledge about its basic requirements causes the plant to grow with various issues. To solve this problem, we have listed 8 caring tips to follow and make your plant flourish and thrive better than any other in your garden.


Keep the plant in direct sunlight for about two hours in the morning. Sunlight is less harsh in the early morning than the rest of the day.

After a couple of hours of morning sunlight, bring the plant inside and place it near a window where bright, indirect sunlight reaches the foliage. These plants can tolerate a maximum of 85 percent of sunlight exposure.


A slightly acidic soil that does not dry out quickly is ideal for your plant. We recommend that you use soil with high organic matter and fibers of sand and coconut.

A soil with a lot of nutrients will help the plant flourish and thrive in no time. Please make sure that you keep the pH of the soil between 5 and 7.


We recommend you water the plant only if the top half of the soil feels dry. It would be best to water the plant more frequently in the summer season when it is actively growing and reduce the watering to every two weeks once the winter season arrives.

Please do not use extremely cold or hot water for your plant as it can cause discoloration of the leaves.


A 55 to 88 degrees Fahrenheit temperature is ideal for these plants to grow healthy. An extremely cold temperature would wilt the leaves, so bring them inside the house in the winter season. Discoloration of the leaves also indicates that the plant requires a warmer temperature.


A very high humidity level of 80 to 90 percent is recommended. However, it is quite difficult to get such high humidity levels inside a house, so we advise you to use a humidifier or fill a saucer with pebbles and water and place it under the plant’s pot to maintain humidity levels.


Feed the plant every two weeks in the growing season with magnesium-rich fertilizer. Reduce the feeding in the winter season as it would do more harm than good.


Pruning can encourage the growth of the leaves and make them look healthier with proper shaping. Remove the yellow leaves as soon as you detect them and trim the excessively grown ones. Make sure that you use thoroughly cleaned equipment before pruning your plant.

Pests and other diseases

Mealybugs and spider mites can make holes in the leaves of the plant. You can remove them with the help of soft cloth dipped in warm water, but make sure that you spray neem oil after you get rid of them to protect your plant from getting infected again.

Propagating Philodendron Ilsemanii

You can easily propagate your plant using the stem cutting method. There are a few tips that you can follow for the best results.

  • Leave a few leaves intact after you make a cut.
  • Cut the stem with a sharp and clean knife.
  • Place the cutting in water and keep it inside until the roots develop a few inches from the cut.
  • Please do not drown the leaves while treating the cut with water.
  • Plant the roots in the soil and water to keep them hydrated.
