Care Instructions

Light:
Provide bright, indirect light for optimal growth and to encourage the vibrant sun-stressed colors. A few hours of gentle morning sun is beneficial, but protect from harsh afternoon rays which can scorch the leaves. For the best red foliage, gradually increase light exposure to push the plant to the edge of “sun stress”.

Water:
Allow the top 1-2 inches of soil to dry out between waterings. Water thoroughly and ensure excellent drainage, as this plant is susceptible to root rot if left in standing water. Reduce watering frequency during the winter months.

Soil:
Use a light, airy, and well-draining potting mix. An aroid blend with orchid bark, perlite, and coco coir or peat is ideal. A mix intended for succulents, cacti, or orchids also works well.

Temperature & Humidity:
Thrives in warm temperatures between 60–80°F (15–27°C). Protect from cold drafts and sudden temperature changes. Prefers moderate to high humidity (60-80%). Boost humidity with a pebble tray or humidifier.

Fertilizer:
Feed with a half-strength, balanced liquid fertilizer once a month during the spring and summer growing season. Reduce or stop feeding in the fall and winter.

Pruning:
Prune lightly in early spring to shape or encourage branching. Important: Do not remove the flower spurs (peduncles), as new blooms form on old growth year after year.
