Care Guide

Taking care of the philodendron cordatum can be started with watering. Assess the soil before pouring water. In a bright light condition, the plant needs water when the pot is half dry. If the plant is placed under the shade, you should water the plant when the soil is 2/3 dry. If it is difficult for you to assess the plant, you can check the foliage. When the foliage begins to curl and wilt, this is a good indication to water the plant.

Furthermore, rotate the plant periodically to ensure promote growth on all sides. You will need to dust the plant too while keeping an eye out for diseases and pests.

Water Requirements

Watering must be the trickiest part when raising a philodendron. If you don’t provide sufficient water, it will cause wilting and curling foliage. If you give excessive water, this will lead to Erwinia blight disease and root rot.

The philodendron cordatum likes water, but the problem is you don’t let the water waterlog the plant. You will need to choose a pot that have good drainage holes so the plant can drain perfectly. Besides, check the moisture of the soil before giving it some drink.

Generally, the first 2-3 inches of the soil determines whether the plant needs water or not. If it is moist, you don’t need to water the plant.

You can use the chopstick method by pushing through it to the soil and see if the color changes with the soil clinging to it. Or, use your first two knuckles to assess the soil.

Light Requirements

In its natural habitat, the philodendron cordatum is found climbing up the trees. It lives under the forest canopy so it is best to place the plant under indirect sunlight. This will thrive well in this condition.

Although it can survive under the shade, low light will not give maximum growth. It will slow the growth. On the contrary, the sunburn will damage the plant’s foliage.

You will need to be careful in this case. Probably placing the plant near the window is a good idea to get sufficient sunlight. A few hours of morning sunlight can also promote growth as long as you don’t burn the foliage.


The philodendron cordatum enjoys high humidity. It prefers humidity levels of 70%-80%. If you are living in a drier area, you probably need to increase the humidity level.

Some ways to increase the humidity level include putting the philodendron near the bathroom or near the area where the humidity level is higher.

You can also place some pebbles on a tray that is filled with water. After that, place the philodendron on top of the pebbles. The plant will get a higher humidity level from the evaporation.

Another way to improve the humidity level is by grouping the plant. It will increase the humidity because the plants create a mini biome.

The last option you can try to increase the humidity level is using a humidifier which you can buy online.
