When and How to Water Your Ring of Fire Plant

Philodendron ‘Ring of Fire’ is a relatively drought-tolerant plant, but it should not be allowed to dry out completely. This plant can withstand brief periods of dryness, thanks to its semi-succulent roots, but prolonged drought will lead to slowed growth and leaf curling. While it doesn’t demand frequent watering like some moisture-loving plants, it is essential to balance hydration to prevent stress.

In the spring and summer, during the active growing season, water your Philodendron 'Ring of Fire' when the top 2 inches of soil feels dry. Depending on the environment, this typically means watering once every 5 to 7 days. Ensure that you water thoroughly until excess drains from the pot’s bottom, allowing the roots to receive ample hydration.

In fall and winter, during the dormant season, the ring of fire plant’s water needs decrease as growth slows. Water only when the top 3-4 inches of soil is dry, which may extend the frequency to once every 10 to 14 days. Overwatering during this time can lead to root rot, so always check soil moisture before watering. If the indoor air is particularly dry due to heating systems, occasional misting can help maintain humidity without overwatering.

Light Requirements – Where to Place Your Philodendron Ring of Fire

When grown indoors as a houseplant, your Philodendron ‘Ring of Fire’ thrives in bright, indirect light for at least 6 to 8 hours daily.

A spot near a north or east-facing window is ideal, where the plant receives filtered sunlight without harsh direct exposure.

South and west-facing windows should have sheer curtains to diffuse strong rays, as too direct sun can scorch the delicate variegated foliage.

If natural light is limited, supplement with a full-spectrum grow light for 10-12 hours daily to maintain healthy growth.

For outdoor cultivation, this Philodendron plant thrives in partial shade to dappled sunlight, making it perfect for placement under a tree canopy or a covered patio.

It benefits from morning sun exposure for at least 2-4 hours and shade during the hottest parts of the day. Avoid prolonged exposure to intense afternoon sun, as it can cause leaf burns, especially on the lighter variegated sections.

Optimal Soil & Fertilizer Needs

Philodendron ‘Ring of Fire’ thrives in well-draining, nutrient-rich soil. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your Philodendron plant to thrive.

During the growing season in the spring, fertilize the plant once a year using a balanced NPK fertilizer. A formulation with lower parts of nitrogen and potassium such as 5-10-5, will encourage strong foliage growth and vibrant variegation. Organic alternatives like worm castings or compost can also provide slow-release nutrients.

In fall and winter, reduce feeding as the plant’s growth naturally slows. Over-fertilizing during dormancy can lead to salt buildup and leaf discoloration.

Hardiness Zones & More

For growing indoors as a houseplant, ring of fire Philodendron requires temperatures between 65-80°F and humidity levels above 60% for optimal growth. Placing a humidifier nearby or using a pebble tray can help maintain consistent moisture in the air. Avoid placing the plant near heating vents or air conditioners, as sudden temperature fluctuations can cause stress.

In the United States, this is mostly an indoor plant, but if you live in southern Florida or

Hawaii then you can cultivate it outdoor in USDA zones 9-11.

It thrives in high humidity environments but should be sheltered from direct afternoon sun to prevent leaf scorch.

If you grow outdoors in cooler zones, bring the plant indoors once temperature drops below 55°F to prevent cold damage.

Some variegation patterns may intensify or change slightly in response to different light conditions.

How to Propagate Your Ring of Fire Philodendron

Philodendron ‘Ring of Fire’ is best propagated by stem cuttings. Select a healthy stem with at least two to three nodes and cut just below a node using sterilized shears.
