How to Care for Your Euphorbia cotinifolia (Caribbean Copper Plant)

The Euphorbia cotinifolia, commonly known as Caribbean Copper Plant, is a striking ornamental tree prized for its deep burgundy foliage and light airy branching. Indoors, it offers a bold pop of color and an elegant, upright form that feels both sculptural and refined. With bright interior conditions, warm temperatures, long dry periods, and stability in placement, this species becomes a vibrant focal point that adds dramatic color and movement to modern interiors.

Light Requirements

• Prefers bright interior light with consistent daily illumination
• Strong light maintains its rich burgundy color and upright branching
• Keep the plant in one stable location so it can acclimate comfortably

Watering Schedule

• Allow the soil to dry at least halfway down before watering
• Drying time varies with indoor temperature, airflow, and seasonal light
• Water slowly and evenly so the soil hydrates without becoming heavy
• Always check dryness below the surface with your finger or a moisture meter

How to Understand Watering Needs

• Caribbean Copper Plant prefers predictable drying periods between waterings
• Leaves may soften or curl slightly when the plant is fully dry
• Yellowing leaves can signal watering too frequently
• A consistent rhythm of partial dryness helps maintain strong roots and rich foliage color

Fertilizer Tips

• Feed monthly during spring and summer with a balanced liquid fertilizer
• Pause feeding during fall and winter when growth slows
• Light, steady fertilization supports vibrant color and branching

Trimming and Pruning

• Prune to maintain shape, encourage branching, or control height
• Make clean cuts above a node to direct new growth
• Remove aging or yellow leaves as needed
• Occasional grooming keeps the tree full and polished

Pest Control and Identifying Issues

• Inspect regularly for spider mites, mealybugs, and scale
• Spider mites appear as tiny speckles or fine webbing
• Mealybugs form soft white clusters in leaf joints
• Scale appears as rounded bumps attached to stems
• Treat pests with neem oil or insecticidal soap until resolved
• Maintain good airflow and clean foliage to prevent reinfestation
• Early detection maintains healthy color and new growth

Common Issues

• Leaf drop: Can occur after relocation or sudden temperature changes
• Yellowing leaves: Often tied to watering too frequently
• Crispy edges: May develop with extended dryness or low humidity
• Faded color: Typically linked to insufficient light

Repotting Notes

• Repot every one to two years, or when roots begin to fill the vessel
• Use a structured indoor potting mix with strong aeration
• Repot in spring so the plant can settle during active growth

Lifespan and Growth

Euphorbia cotinifolia grows quickly under strong light, forming a tall, airy canopy of deep red foliage. Over time, it becomes a bold architectural specimen that brings height, color, and dramatic contrast to bright interior spaces.
