🌿 Philodendron subhastatum – Care Guide

Philodendron subhastatum is a stunning tropical aroid prized for its bicolor foliage—the top side of the leaf is deep green, while the underside reveals a rich red to maroon hue, especially as it matures. It’s a climbing philodendron, ideal for those who appreciate bold foliage with a surprise twist.

☀️ Light

• Prefers bright, indirect light to maintain vibrant colors.

• Can tolerate moderate light, but too little light may reduce red pigment on the underside.

• Avoid direct sunlight—can cause leaf burn.

💧 Watering

• Water when the top 2–3 cm (1 inch) of soil feels dry.

• Keep soil lightly moist, not soggy.

• Let excess water drain—no standing water.

• Reduce watering in cooler seasons.

🌱 Soil

• Grows best in a chunky, well-draining aroid mix:

  Potting mix + orchid bark + perlite + coco peat or charcoal.

• Needs good airflow to the roots to prevent rot.

💦 Humidity

• Enjoys high humidity (60–80%) for best growth and color.

• Can adapt to household humidity but thrives in tropical conditions.

• Use a humidifier, mist regularly, or place on a pebble tray.

🌡️ Temperature

• Ideal range: 18–28°C (65–82°F).

• Keep above 12°C (54°F) and avoid cold drafts.

• Not frost-tolerant—suitable as a houseplant in cooler climates.

🍃 Fertilizer

• Feed every 4–6 weeks in the growing season with a balanced, diluted liquid fertilizer.

• Avoid overfeeding—flush soil occasionally to prevent salt buildup.

• Stop fertilizing in winter.

✂️ Growth Habit & Support

• Subhastatum is a climber—encourage vertical growth with a moss pole, stake, or trellis.

• Larger, more elongated leaves develop when climbing.

• Prune occasionally to control size or remove yellowing leaves.

✨ Special Features

• Underside of the leaves develops a rich burgundy to red color as the plant matures.

• Adds depth and contrast to your indoor jungle.

• A must-have for aroid collectors and foliage lovers.

✅ Styling Tips

• Display on a moss pole for an upright statement.

• Place where you can appreciate the two-toned foliage—slightly above eye level or hanging.

• Pairs beautifully with silver, variegated, or dark-leaved plants.

⚠️ Pet Safety

• Toxic if ingested (contains calcium oxalate crystals).

• Keep away from pets and children.
