**Ideal range**: 65-80°F (18-27°C) - **Tolerance**: 60-85°F (15-29°C) - **Consistency**: Avoid dramatic temperature changes - **Cold sensitivity**: Damage below 60°F (15°C) ### Humidity Requirements - **Preferred range**: 40-50% humidity - **Tolerance**: Adapts to 35-60% humidity - **Benefits**: Higher humidity promotes larger leaves - **Dry air problems**: Can cause brown leaf edges ### Increasing Humidity - **Pebble trays**: Place pot on water-filled pebble tray - **Grouping plants**: Creates beneficial microclimate - **Humidifiers**: Most consistent method - **Room selection**: Bathrooms naturally more humid ### Environmental Factors - **Air circulation**: Gentle airflow prevents fungal issues - **Drafts**: Protect from cold or hot air currents - **Stable conditions**: Consistent environment promotes best growth ## Fertilizing Schedule ### Growing Season Feeding - **Frequency**: Monthly from spring through early fall - **Type**: Balanced liquid fertilizer (20-20-20) - **Dilution**: Use at half recommended strength - **Application**: Apply to moist soil only ### Fertilizer Effects - **Adequate nutrition**: Promotes large, colorful leaves - **Over-fertilizing**: Can cause salt buildup and leaf burn - **Consistent feeding**: Regular light feeding better than heavy doses - **Variegation support**: Proper nutrition maintains patterns ### Winter Feeding - **Reduced frequency**: Every 6-8 weeks or stop - **Slower growth**: Plants need less nutrition in winter - **Resume timing**: Begin regular feeding when growth resumes ### Organic Options - **Compost tea**: Gentle, natural nutrition - **Fish emulsion**: Good for foliage development - **Worm castings**: Slow-release soil amendment ## Pruning and Maintenance ### Regular Maintenance - **Remove yellow leaves**: Cut off aging or damaged foliage -
