🪴 Care & Maintenance Guide

🌞 Light

• Best: Bright, indirect light (best for blooms)

• Tolerates: Medium light (fewer blooms)

• Avoid: Direct hot sun (leaf scorch) and very low light (slow growth)

💧 Watering

• Water when the top 1–2 inches of soil begin to dry

• Keep soil lightly moist but never soggy

• Tip: Good drainage is essential—overwatering is the #1 issue

🪨 Soil

• Use a chunky, well-draining aroid mix (orchid bark + perlite + peat/coco coir)

• Containers must have drainage holes

• Tip: Airy soil keeps roots healthy and encourages blooming

🌡️ Temperature & Humidity

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

• Prefers moderate to higher humidity (helps blooms and leaf edges)

• Avoid cold drafts and temperatures below 60°F (16°C)

🌿 Fertilization

• Feed every 4–6 weeks during spring and summer

• Use a balanced houseplant fertilizer at label rate

• Reduce feeding in fall/winter

✂️ Pruning

• Remove yellowing leaves at the base with clean scissors

• Remove spent blooms at the stem base to encourage new growth

• Wipe leaves occasionally to keep them glossy and dust-free

⚠️ Common Issues

• No blooms: insufficient light or low nutrition

• Brown leaf edges: low humidity, inconsistent watering, or salt buildup

• Yellow leaves: overwatering or poor drainage

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