How to Grow Geranium (Pelargonium) ‘Calliope Large Orange Splash’
The ‘Calliope Large Orange Splash’ geranium is a reliable and eye-catching plant that thrives with minimal care. Follow these guidelines to enjoy its stunning blooms throughout the season:
1. Choosing the Right Location Geraniums flourish in sunny locations with good air circulation.
- Outdoors: Select a spot that receives at least 6-8 hours of direct sunlight daily. Partial shade is acceptable in areas with intense afternoon heat.
- Indoors: Place near a south- or west-facing window where it gets bright, indirect light. Supplement with grow lights if necessary.
2. Soil Requirements Well-draining soil is essential for preventing root rot and promoting healthy growth.
- Outdoor Beds: Amend the soil with compost or organic matter to improve fertility and drainage.
- Containers: Use a lightweight, well-draining potting mix designed for flowers or container plants. Ensure the container has drainage holes.
- pH Range: Slightly acidic to neutral soil (pH 6.0-7.0) is ideal.
3. Planting
- Timing: Plant outdoors after the danger of frost has passed. Geraniums can be started indoors year-round.
- Spacing: Space plants 12-18 inches apart in garden beds to allow for proper airflow and growth.
- Depth: Plant at the same depth as in the nursery pot, ensuring the crown is level with the soil surface.
4. Watering Geraniums require consistent but moderate watering to thrive.
- Newly Planted: Water thoroughly to establish roots.
- Established Plants: Water when the top inch of soil feels dry. Avoid overwatering, as geraniums prefer slightly dry conditions.
- Containers: Check moisture levels frequently, as pots dry out faster than in-ground plantings.
5. Light Requirements
- Full Sun: Promotes prolific blooming and healthy foliage.
- Partial Shade: Suitable for areas with intense midday heat, particularly in warmer climates.
6. Temperature and Humidity
- Optimal Temperature: 65°F to 75°F (18°C to 24°C) during the day and 55°F to 65°F (13°C to 18°C) at night.
- Humidity: Moderate humidity is preferred, but geraniums tolerate drier conditions well.
7. Fertilizing Feed your geranium regularly during the growing season to ensure continuous blooming.
- Frequency: Fertilize every 2-4 weeks with a water-soluble fertilizer.
- Type: Use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20.
- Avoid Over-Fertilizing: Too much fertilizer can lead to lush foliage with fewer blooms.
8. Deadheading and Pruning
- Deadheading: Remove spent flowers regularly to encourage new blooms and maintain a tidy appearance.
- Pruning: Trim back leggy or overgrown stems in early spring or midsummer to promote bushier growth.
9. Overwintering In cooler climates, ‘Calliope Large Orange Splash’ geraniums can be overwintered indoors or treated as annuals.
- Indoors: Before the first frost, move potted plants indoors and place them in a bright, cool location. Reduce watering during dormancy.
- Cuttings: Take stem cuttings in late summer and root them indoors for fresh plants in the spring.
10. Pest and Disease Management While generally hardy, geraniums can occasionally face pest or disease issues.
- Pests: Watch for aphids, whiteflies, and spider mites. Treat infestations with insecticidal soap or neem oil.
- Diseases: Prevent fungal diseases like botrytis and powdery mildew by ensuring good air circulation and avoiding overhead watering.
- Yellowing Leaves: Often caused by overwatering or nutrient deficiencies. Adjust care practices accordingly.

- Petunias: Add vibrant, contrasting colors.
- Lobelia: Provides trailing blue or purple accents.
- Dusty Miller: Offers silvery foliage that enhances the orange and red blooms.

12. Container Gardening Tips ‘Calliope Large Orange Splash’ geraniums thrive in pots and hanging baskets:
- Use a container with drainage holes to prevent waterlogging.
- Choose a pot slightly larger than the root ball to allow room for growth.
- Combine with trailing plants like ivy or sweet potato vine for a dynamic arrangement.
13. Troubleshooting Common Issues
- Lack of Blooms: Ensure the plant receives sufficient sunlight and avoid over-fertilizing with nitrogen-heavy formulas.
- Wilted Leaves: May indicate underwatering or root rot from overwatering. Check soil moisture levels and adjust as needed.
