Philodendron: Ring of Fire
Sunlight
Place your Philodendron Ring of Fire in bright, indirect light but it can tolerate morning direct sun. Avoid exposing it to direct afternoon sunlight, as it can scorch the delicate leaves. This plant is not suited for low light conditions as it can cause etiolation and loss of color. A spot near a West or East-facing window is usually ideal.
Not sure if your space will provide enough light? Consider measuring light to ensure your Philodendron will receive enough. If you find your space doesn't provide enough light then consider installing a grow light to keep over the plant for 8-12 hours a day.
Water
Allow the soil to dry out between waterings. Stick your finger into the soil or use a moisture meter to gauge moisture levels. Water thoroughly when the soil is completely dry, ensuring that excess water drains from the pot's bottom. Avoid letting the plant sit in standing water, as this can lead to root rot.
Humidity
The Philodendron Ring of Fire will appreciate higher humidity levels. If your indoor environment is dry, consider placing a wet pebble tray underneath the plant to increase humidity.
You can also use a humidifier to keep the air around your Philodendron moist more consistenly, especially during the Winter months when indoor air tends to be dry. Not sure if humidity is high enough? You can measure the level of humidity with a hygrometer or LTH meter.
