How to Grow Cleome
Growing Cleome, a resilient and vibrant flower, is a fulfilling task for any gardener. Understanding the right conditions and care is crucial for their successful growth.
Ideal Growing Conditions
Cleomes thrive in conditions that mimic their natural habitat. A full sun location is ideal, as it promotes healthy growth and vibrant blooms. They also prefer organically rich, well-draining soil.
Temperature and Sunlight Requirements
| Condition | Requirement |
| Sunlight | Full sun to light shade |
| Soil Type | Well-drained, organically rich |
| Temperature for Seed Germination | Daytime: 75-85°F, Nighttime: 10°F lower |
Seed Germination Tips
Cleome seeds require specific conditions to germinate effectively. Maintain fluctuating temperatures and keep the soil moist but not wet. Starting the seeds indoors is a popular method, especially in regions with shorter growing seasons.
Indoor Sowing Guide
| Activity | Detail |
| Start Indoors | 6-8 weeks before the last frost |
| Soil Moisture | Keep moist, not wet |
| Seedling Spacing | 6-8 inches apart |
Transplanting Seedlings
Once the seedlings reach 2-4 inches tall and the risk of frost has passed, they can be transplanted outdoors. It’s important to harden off the seedlings by gradually exposing them to outdoor conditions.
Transplanting Steps
- Harden off seedlings: Gradually increase outdoor exposure.
- Dig holes: As deep and wide as the root balls.
- Spacing: 6-8 inches apart.
- Water: Thoroughly after planting.
Self-Seeding Properties
Cleome is known for its ability to self-seed, making it a low-maintenance choice for many gardeners. In ideal conditions, they can reseed themselves, providing a continuous display year after year.
Where to Grow Cleome
Selecting the right location for planting Cleome is critical for its optimal growth and blooming.
Optimal Garden Locations
Cleomes are versatile and can grow in a variety of locations. However, they perform best in areas that receive full sun to light shade. They are adaptable to different soil types, but prefer a nutrient-rich, well-drained medium.
Ideal Soil Conditions
