  • Well-draining soil
  • Bright, indirect sunlight
  • Humidity of at least 60%

Light

Philodendrons will thrive in environments with medium to bright, indirect sunlight. Indirect sunlight means that the light is filtered through another source before hitting the plant.

Partial or dappled shade is great for this plant, as it mimics the rainforest habitat where it originated.  You can use special curtains or even other houseplants to achieve this effect.

Footcandles are another great way to measure light. Footcandles (FCs) are the units used by light meters to determine the amount of sunlight in a room.

With philodendrons, you will want an average amount of 200 FCs, with at least 100 FCs present for minimal growth.

There are several ways to achieve this lighting environment, even without a light meter. If you place your philodendron Atabapoense near an eastern or northern facing window, it will get bright, indirect sunlight for the majority of the day.

Placing this plant in a cluster of others near a northern window will be a simple way to achieve the shaded effect.

Best Soil and Mixture Type

Potting mixtures can present the ideal combination of rich organic matter with well-draining abilities. Here are some elements to look out for!

  • Peat moss, which assists with retaining nutrients
  • Perlite, to help with drainage and retention.
  • Orchid bark, which helps with drainage
  • Coco coir, to improve moisture retention

These are all excellent elements to find in philodendron soil.

With at least a few, you will find a great combination of well-draining soil that still allows moisture retention and absorbing nutrients.

Drooping and brown leaves, as well as dry soil, are good signs that this plant is suffering from a lack of water.

Keep in mind that the soil will dry out faster in the summer and slower in the winter, so this should impact your watering schedule.

Always make sure to feel the first inch or so of the soil before watering to ensure it is needed.
