2. Light Requirements

One of the most distinctive features of Alabama Sunset Coleus is its ability to change leaf color based on light exposure.

Full Sun vs. Shade

• Full Sun (6+ hours/day): Leaves develop intense pink and golden tones.
• Partial Shade (3-6 hours/day): Foliage transitions to a mix of reds and burgundies.
• Full Shade (Less than 3 hours/day): Richer burgundy and deeper red hues dominate.

For optimal color vibrancy, provide morning sun with afternoon shade, especially in hot climates where full midday sun may scorch the leaves.

3. Soil and Planting Requirements

Proper soil preparation is crucial for the healthy growth of Alabama Sunset Coleus.

Soil Preferences

• Type: Well-draining, loose soil
• pH Range: Slightly acidic to neutral (6.0-7.0)
• Amendments: Add compost or organic matter to improve soil structure and fertility.

Planting Guidelines

• Space plants 12-18 inches apart to allow for air circulation.
• Plant in spring after the last frost if growing outdoors.
• For containers, use high-quality potting soil and ensure proper drainage.

4. Watering and Humidity Needs

Alabama Sunset Coleus requires consistent moisture but should not sit in soggy soil.

Watering Schedule

• Outdoor Plants: Water deeply 2-3 times per week during dry spells.
• Container Plants: Check daily; water when the top inch of soil feels dry.
• Indoor Plants: Water every 5-7 days, adjusting based on humidity levels.

Humidity Considerations

• Prefers moderate to high humidity (50% or more).
• If grown indoors, mist occasionally or place a humidity tray nearby.

5. Fertilization and Feeding

Regular feeding encourages lush growth and vibrant colors.

Fertilizer Type

• Use a balanced, water-soluble fertilizer (10-10-10 or 20-20-20) every 2-4 weeks during the growing season.
• Organic options like compost tea or fish emulsion can be used for sustainable growth.

Seasonal Feeding Schedule

• Spring-Summer: Fertilize every 2-4 weeks.
• Fall-Winter: Reduce feeding if plant growth slows indoors.

6. Pruning and Maintenance

Regular pruning keeps the plant compact and encourages bushier growth.

Pruning Tips

• Pinch back growing tips every few weeks to prevent legginess.
• Remove flower spikes as they appear to redirect energy to foliage production.
• Trim any damaged or overly long stems to maintain shape.

7. Propagation Methods

Coleus is easy to propagate through stem cuttings, making it an excellent choice for gardeners who want to expand their collection.

Steps for Propagation

1. Take a 4-6 inch cutting from a healthy stem just below a node.
2. Remove the lower leaves and place the cutting in water or moist soil.
3. Keep in a warm, bright location out of direct sunlight.
4. Roots should develop within 1-2 weeks, after which the cutting can be transplanted.

8. Pest and Disease Management

Although relatively pest-resistant, Alabama Sunset Coleus can sometimes attract common garden pests.

Common Pests

• Aphids: Cause curling leaves; treat with insecticidal soap.
• Spider Mites: Create webbing and cause yellowing; control with neem oil.
• Whiteflies: Can weaken plants; use sticky traps or insecticidal soap.

Common Diseases

• Powdery Mildew: Appears as white powdery spots; improve air circulation and use a fungicide if necessary.
• Root Rot: Caused by overwatering; ensure proper drainage and avoid excessive moisture.

9. Overwintering Alabama Sunset Coleus

In colder climates, Coleus must be protected from frost to survive the winter.

Bringing Plants Indoors

• Before the first frost, dig up outdoor plants and transplant them into pots.
• Place in a bright, warm location indoors.
• Reduce watering slightly during the winter months.

Taking Cuttings for Winter Storage

• If space is limited, take stem cuttings and root them indoors.
• Store in a warm spot and transplant back outside in spring.
