40% peat moss or coconut coir - 30% regular potting soil - 20% perlite - 10% compost or leaf mold ### Container Selection - **Drainage holes**: Essential for proper drainage - **Hanging baskets**: Traditional and ideal display - **Size**: Wide, shallow containers work well - **Material**: Plastic retains moisture better than terracotta ### Repotting Schedule - **Frequency**: Every 1-2 years - **Timing**: Early spring before growing season - **Size increase**: Go up one pot size only - **Division**: Good time to divide overcrowded plants ## Temperature and Environmental Conditions ### Temperature Preferences - **Ideal range**: 60-70°F (15-21°C) - **Tolerance**: 55-75°F (13-24°C) - **Consistency**: Avoid dramatic temperature changes - **Cold sensitivity**: Damage below 50°F (10°C) ### Environmental Factors - **Air circulation**: Gentle air movement beneficial - **Drafts**: Protect from cold or hot air currents - **Heating/cooling**: Keep away from vents - **Seasonal changes**: Monitor for environmental stress ## 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**: Only fertilize moist soil ### Winter Feeding - **Frequency**: Reduce to bi-monthly or stop - **Growth response**: Less active growth needs less nutrition - **Resume timing**: Begin regular feeding when growth resumes ### Organic Options - **Compost tea**: Gentle, natural nutrition - **Fish emulsion**: Excellent for foliage growth - **Worm castings**: Slow-release soil amendment - **Liquid kelp**: Provides beneficial trace minerals ## Propagation Methods ### Division (Most Common) 1. **Timing**: During repotting in spring 2. **Root examination**: Look for natural division points 3. **Gentle separation**: Use hands or clean knife 4. **Individual plants**: Each division needs roots and fronds 5. **Immediate care**: Plant and water right away ### Spore Propagation (Advanced) 1. **Spore collection**: Gather from mature fronds 2. **Sterile conditions**: Use sterilized growing medium 3. **Consistent moisture**: Keep growing medium moist 4. **Patience**: Takes several months for development 5. **Transplanting**: Move when large enough to handle ### Runner Propagation 1. **Identify runners**: Look for plantlets on stolons 2. **Root development**: Allow runners to develop roots 3. **Separation**: Cut from parent when well-rooted 4. **Independent growth**: Plant in appropriate soil mix ## Common Problems and Solutions ### Brown, Crispy Fronds **Primary cause**: Low humidity **Solutions**: -
