Being a trailing Philodendron, the sweetheart plant makes a perfect plant for hanging baskets.

Philodendron Cordatum Care

Being a hardy and versatile plant, this Philodendron may be grown in a range of different habitats. 

Philodendron Cordatum Soil

Philodendron Cordatum likes to have sandy, quick-draining soil. A perfect growing medium may be created by mixing peat or coco coir to perlite at a 2:1 ratio. Additionally, wood bark may be added to improve the texture of the soil, help in draining excess water, and provide more oxygenation and dampness. 

Philodendron Cordatum Fertilizer

Being a very quick grower with lush foliage, the sweetheart plant will benefit from a monthly feeding from a balanced fertilizer during the warm growing season, especially as new leaves are growing. However, feeding may be reduced to every other month during the wintertime. 

Philodendron Cordatum Watering

During the warm growing spring and summer season, the soil of your Philodendron Cordatum should be kept liberally moist. When watering, the soil should be fully saturated. Still, any excess water should drain, and the plant should not be allowed to sit in excess moisture within the plant’s drainage tray. During the winter, the Philodendron’s soil should be allowed to dry out some between waterings. 

Philodendron Cordatum Light Requirements

Being a very hardy and versatile plant, this Philodendron can thrive in various conditions. This plant prefers bright indirect light but will tolerate low-light conditions. 

Philodendron Cordatum Temperature & Humidity

Having tropical rainforest origins, this plant likes to remain warm and humid. It should be kept at temperatures between 60-75 degrees Fahrenheit. Growth will slow if kept at temperatures that are any higher or lower. It is also important to note that Philodendron Cordatum will not enjoy large fluctuations in temperature and should not be kept near cold windows, AC units, heaters, or drafts. Though enjoying humid environments and misting, this species is tolerant of dry conditions. 

Repotting Philodendron Cordatum

When roots become tight and compact or are seen poking out from the drainage holes, this Philodendron should be repotted. Repotting should be completed in early spring before new growth has begun. Select a container that is 2-4 inches larger than the previous pot. Repot your plant, refresh the soil, tamp lightly, water thoroughly, and place in indirect light to become reestablished. 

Philodendron Cordatum Maintenance & Pruning

Pruning of your Philodendron Cordatum is easy – and you may propagate it easily at the same time. As this Philodendron has a trailing growth habit and is a rapid grower, regular pruning will likely be necessary to control its size. Pruning may be done periodically using sharp pruning shears to trim away old, dead, diseased, or discolored branches or leaves or to maintain the shape and density of your plant.
