Light is crucial for your Split-Leaf Philodendron's growth and health.

In their native habitats, these plants often grow in full sun when temperatures are mild, and they tend to grow larger and more quickly in these conditions.

However, most plants sold for indoor use are accustomed to greenhouse environments and may suffer from leaf burn when suddenly exposed to full sun.

Start by placing your plant near a south-facing window with a sheer curtain and introduce it to direct sunlight gradually, beginning with just a few hours of morning sun in spring.

If the leaves show signs of burning, continue using the curtain to diffuse the light and avoid exposing them to harsh afternoon sun during summer, especially when filtered through glass.

To ensure your plant receives enough light to survive, place it less than 6 feet from a south-facing window.

For healthy, moderate growth, bright indirect light or some gentle morning sun in front of an east-facing window is your best option.
