- **Artificial light**: LED grow lights work excellently
### Light Effects on Color
- **Adequate light**: Vibrant, saturated colors
- **Insufficient light**: Colors fade, become muddy
- **Too much direct sun**: Leaf scorch, fading
- **Consistent lighting**: Maintains stable coloration
## Watering Guidelines
### Moisture Requirements
- **Consistently moist**: Prefer evenly moist soil
- **Not waterlogged**: Good drainage essential
- **Regular watering**: Check soil daily during growing season
- **Wilting indicator**: Droops quickly when thirsty
### Watering Technique
- **Deep watering**: Water thoroughly until drainage appears
- **Morning watering**: Best time for water absorption
- **Avoid leaves**: Water soil, not foliage when possible
- **Room temperature water**: Avoid temperature shock
### Seasonal Watering
- **Growing season**: More frequent watering needed
- **Winter**: Reduce frequency if growth slows
- **Humidity correlation**: Higher humidity = less frequent watering
- **Container size**: Smaller pots dry faster
## Soil and Potting
### Soil Requirements
- **Well-draining**: Essential for root health
- **Organic-rich**: High organic matter for nutrition
- **Moisture-retentive**: Holds water but drains excess
- **pH range**: Neutral to slightly acidic (6.0-7.0)
### Soil Mix Recipe
- 50% high-quality potting soil
- 25% peat moss or coconut coir
- 25% perlite or vermiculite
- Optional: compost for extra nutrition
### Container Considerations
- **Drainage holes**: Essential for proper drainage
- **Size**: Appropriate for root system and plant size
- **Material**: Any material with good drainage
- **Depth**: Standard depth containers work well
### Repotting Schedule
- **Fast growth**: May need repotting 2-3 times per season
- **Spring start**: Begin season with fresh soil
- **Size up**: Go up one pot size when roots fill container
- **Fresh soil**: Always use fresh, nutrient-rich mix
## Temperature and Environmental Conditions
### Temperature Preferences
- **Ideal range**: 65-75°F (18-24°C)
- **Tolerance**: 60-80°F (15-27°C)
- **Heat sensitivity**: Struggles above 85°F (29°C)
- **Cold sensitivity**: Damage below 50°F (10°C)
### Humidity Requirements
- **Preferred range**: 40-50% humidity
- **Tolerance**: Adapts to 30-60% humidity
- **Benefits**: Higher humidity prevents edge browning
- **Indoor air**: Monitor during heating/cooling seasons
### Environmental Factors
- **Air circulation**: Good airflow prevents fungal issues
- **Protection**: Shield from hot, dry winds
- **Stable conditions**: Consistent environment promotes best color
- **Seasonal adjustment**: May need environmental modifications
## Fertilizing Schedule
### Regular Feeding
- **Frequency**: Every 2-3 weeks during growing season
- **Type**: Balanced liquid fertilizer (20-20-20)
- **Dilution**: Use at half recommended strength
- **Application**: Apply to moist soil only
### Fertilizer Effects
- **Adequate nutrition**: Promotes vibrant colors and fast growth
- **Over-fertilizing**: Can cause weak, leggy growth
- **Nitrogen balance**: Too much nitrogen reduces color intensity
- **Consistent feeding**: Regular light feeding better than heavy doses
### Organic Options
- **Compost tea**: Gentle, natural nutrition
- **Fish emulsion**: Good for foliage growth
- **Worm castings**: Slow-release soil amendment
- **Balanced organic**: Water-soluble organic fertilizers
## Pinching and Pruning
### Flower Removal (Critical)
- **Pinch flower spikes**: Remove as soon as they appear
- **Energy conservation**: Keeps energy focused on foliage
- **Color maintenance**: Prevents color fading during flowering
- **Regular monitoring**: Check weekly for flower development
### Pinching for Bushiness
- **Tip pinching**: Remove growing tips to encourage branching
- **Frequency**: Pinch every 2-3 weeks during growing season
- **Method**: Use fingers or clean scissors
- **Result**: Creates fuller, bushier plants
### Pruning Techniques
- **Shape control**: Prune to maintain desired size and shape
- **Leggy growth**: Cut back long, stretched stems
- **Dead heading**: Remove any damaged or dead foliage
- **Propagation material**: Use pruned stems for cuttings
## Propagation Methods
### Stem Cutting Propagation
1. **Select cuttings**: 4-6 inch healthy stem tips
2. **Remove lower leaves**: Leave 2-4 sets of top leaves
3. **Water or soil**: Root in water or moist potting mix
4. **High humidity**: Cover with plastic if rooting in soil
5. **Quick rooting**: Roots develop in 1-2 weeks
### Water Propagation
1. **Prepare cuttings**: Clean cuts just below leaf nodes
2. **Place in water**: Submerge bottom 2 inches in water
3. **Change water**: Replace every 3-5 days
4. **Root development**: Substantial roots in 10-14 days
5. **Plant**: When roots are 2-3 inches long
### Soil Propagation
1. **Prepare mix**: Use moist, well-draining potting soil
2. **Insert cuttings**: Plant 2 inches deep
3. **Maintain humidity**: Cover with plastic dome
4. **Bright, indirect light**: Avoid direct sun during rooting
5. **Water carefully**: Keep soil moist but not soggy
## Common Problems and Solutions
