Heartleaf philodendron hanging

The heartleaf philodendron (Philodendron scandens) is native to South and Central America and the West Indies. It is a very popular houseplant, offering year-round beauty and easy care. It’s also known as the “sweetheart plant” for its heart-shaped green leaves. It is often given for anniversary gifts due to its association with romance. The leaves are dark green but when they first emerge they’re often bronze-colored, giving this plant plenty of visual interest. On rare occasions, a mature plant might produce small greenish white flowers.

CARE AND NURTURE

Light

This plant does best in bright, indirect light so choose an indoor location that does not receive direct sunlight. This plant requires a good amount of light and you’ll know it’s receiving enough light if growth remains vigorous and the leaves are between two to four inches long. Too much direct sunlight will scorch its leaves.

Soil

Use a good basic soilless potting mix with plenty of peat moss. You can add some perlite for better drainage if you wish. Soilless mixes do not contain any nutrients, so you might want provide some slow-release fertilizer if its not already included in the mix. You can also can make your own potting mix with peat moss, perlite, vermiculite, and some used coffee grounds, too.

Water

Use tepid water, not cold water, to water your houseplants. Cold water can harm a tropical plant by shocking its root system too suddenly. Be careful not to overwater this plant. If the leaves turn yellow, that’s usually a sign of overwatering. Let the soil dry out to the touch between waterings, and make sure you choose a container that has good drainage.

Temperature and Humidity

The heartleaf philodendron, despite being of tropical origins, tolerates dry air quite well but prefers to be in environments with 40% humidity. Higher humidity levels might cause problems, sometimes leading to fungus on leaves.

If your heartleaf philodendron has a tendency to develop fungus, be careful to dry off leaves after watering and let the soil dry out between waterings. This plant is also sensitive to extreme heat so be sure to keep it away from heat sources and direct sunlight.

Fertilizer

You can apply a diluted fertilizer solution once or twice during the active growth season in spring and summer. Do not feed during the winter.

Potting and Repotting

You should repot your heartleaf philodendron every two to three years. Repotting can help prevent root rot and keep the plant’s root system healthy. Gently loosen the potting soil around the root system and add new potting soil to the new container (be sure the container has good drainage holes). Water the plant lightly after settling it into its new pot.
