🪴 Care & Maintenance Guide

🌞 Light

• Best: Bright, indirect light indoors

• Outdoors: Partial shade to filtered sun (morning sun is ideal)

• Avoid: Harsh afternoon sun (leaf scorch) and very low light (slower growth)

💧 Watering

• Water when the top 2 inches of soil begin to dry

• Keep soil evenly moist but never soggy

• Tip: Consistent moisture helps size-up leaves; drainage prevents root issues

🪨 Soil

• Rich, well-draining aroid mix (potting mix + bark + perlite)

• Containers must have drainage holes

• Outdoors: amend soil with compost and ensure good drainage

🌡️ Temperature & Humidity

• Ideal temperature: 65–85°F (18–29°C)

• Prefers moderate to higher humidity

• Avoid cold drafts and temperatures below 55°F (13°C)

🌿 Fertilization

• Feed every 4–6 weeks during spring and summer

• Use a balanced fertilizer at label rate

• Reduce feeding in fall/winter

✂️ Pruning

• Remove old/yellow leaves at the base as needed

• Trim to manage size (wear gloves—sap can irritate)

• Wipe leaves occasionally to remove dust

⚠️ Common Issues

• Yellow leaves: overwatering or poor drainage

• Brown edges: underwatering, low humidity, or salt buildup

• Slow growth: insufficient light or underfeeding

• Pests: spider mites/mealybugs—treat early if detected
