Philodendron Congo Plant

A Philodendron Congo is one of several cultivars of Philodendron that has been developed by growers over the last few years. This is a plant that can adapt to all kinds of conditions as long as you keep it warm. Its care instructions can be used for the following other Philodendron hybrids: Imperial Red, Black Cardinal, Moonlight, Red Emerald, and Autumn. Many philodendrons are climbers, but not this one. A Philodendron Congo is a self-header that spreads outward as it grows upward. The glossy, dark green, thick leaves are spaced very close to each other on a single stem. The stiff, barely visible stem, keeps a Philodendron Congo upright and elegant looking as it matures. These plants are considered poisonous and should be kept away from pets and children.

Plant Care


A Philodendron Congo can grow almost anywhere except in the direct sun. In low light the plant often looks stretched out as it tries to reach for the light.


Always allow the top 50% of the soil to dry out before watering a Philodendron. When watering, cover the entire surface to prevent leaf problems because of dry soil areas.


Fertilize monthly when the plant is actively growing with a balanced food diluted to 1/2 the recommended strength. If the plant is not producing new leaves, it doesn’t need plant food.


Philodendron Congos grow well in normal household temperatures between 70°-85°F (21.1° 29.4°C). Keep these plants away from cold drafts and air conditioners.


Higher humidity is a plus, but philodendrons do well in basic household humidity.


Aphids and mealy bugs


Although high humidity helps a Congo grow well, it also encourages Erwinia Blight.


Use a rich quick-draining soil for philodendrons. You may have to add a little sand to your usual soil mix.

Pot Size

A Philodendron Congo is usually found in 6”, 8”, and 10” containers. They are slow growers and do not need frequent repotting.


A Philodendron Congo rarely needs pruning.


Growers use tissue cultures to propagate this Philodendron hybrid. You can use off- shoots or air layering if you want to try to propagate a Congo.
