The Syngonium 'Pink Splash' is a gorgeous cultivar of the arrowhead vine, adored for its vibrant splashes of pink on green, arrow-shaped leaves. While relatively easy to care for, understanding its rainforest origins and a few key preferences will ensure it thrives.

Light: The Key to Pink Perfection

  • Ideal Light: Bright, indirect light maximizes the pink variegation. An east or west-facing window is perfect. Too little light and the pink fades to green.
  • Watch for Signs: If the pink variegation fades or leaves revert entirely to green, move your plant to a brighter spot gradually. Direct sun causes leaf scorch, so introduce increased light slowly.

Watering: Striking the Balance

  • Soil Check: Water when the top 1-2 inches of soil are dry. Stick your finger in to check; if it's moist, wait another day or two.
  • Thorough Soak: When watering, do so deeply until water runs out the drainage holes. This prevents salts and minerals from accumulating in the soil.
  • Seasonal Adjustments: Reduce watering slightly in winter when growth slows, but don't let the soil dry out completely.

Humidity Boost for Rainforest Vibes

  • Humidifier: The ideal humidity range is 50-60%. A humidifier is the best way to achieve this, especially in dry climates or during winter.
  • Misting: Regular misting helps, but it only temporarily raises humidity. Place the pot on a pebble tray partially filled with water for a consistent boost.
  • Grouping Plants: Placing your Pink Splash near other humidity-loving plants creates a beneficial microclimate.

Temperature: Tropical Comfort

  • Warm and Cozy: This plant thrives in temperatures between 60-85°F (15- 30°C). Protect it from cold drafts and sudden temperature fluctuations.

Soil and Feeding

  • Well-draining Mix: A loose, well-draining soil with organic matter is key. Mix standard potting soil with perlite or coco coir for improved aeration.
  • Light Feeding: During spring and summer, fertilize every 4-6 weeks with a balanced, diluted liquid fertilizer. Stop fertilizing completely during fall and winter.

Potting and Repotting

  • Repotting Signs: Repot when roots are poking out the drainage holes or the plant looks too big for its pot. Spring is the best time for repotting.
  • Pot Choice: Terracotta pots can dry out faster, plastic retains moisture. Choose based on your watering habits. Always pick a pot with good drainage.

Pruning, Training, and Propagation

  • Controlling Growth: Regular pruning encourages bushier growth and helps manage size.
  • Where to Cut: Cut stems just above a leaf node (where leaves sprout from) to encourage branching. Save healthy stem cuttings for propagation!
  • Training: For a vining look, provide support like a moss pole or trellis.
  • Propagation - Step by Step:
    1. Select Cuttings: Choose healthy stems with at least 2-3 leaves and a few nodes.
    2. Cutting: Make a clean cut just below a bottom node.
    3. Rooting Methods:
      • Water: Place cuttings in a jar of water, changing it every few days. Roots will form in a few weeks.
      • Soil: Plant cuttings directly into moist, well-draining potting mix. Keep consistently moist and in bright, indirect light.
    4. Transplanting: Once roots are well-developed (several inches), plant your new Pink Splash babies into their own pots.
