Planting Osteospermum: Getting Started
Osteospermum can be grown from seed or from seedlings. Here’s a step-by-step guide on how to plant osteospermum:
From Seed:
1. Start seeds indoors: Sow seeds 6-8 weeks before the last frost date in your area. Use a seed starting mix and place the seeds ¼ inch deep.
2. Provide warmth and light: Keep the seeds moist and warm (70-75°F). They should germinate in 7-10 days.
3. Harden off seedlings: Once the seedlings have a few true leaves, gradually acclimate them to outdoor conditions for a week or two before planting them in the garden.
4. Plant outdoors: After the last frost, transplant the seedlings into a sunny location in your garden. Space them 12-18 inches apart.
From Seedlings:
1. Choose healthy seedlings: Look for seedlings that are free of pests and diseases.
2. Prepare the soil: Dig a hole twice as wide and as deep as the seedling’s root ball. Amend the soil with compost or other organic matter to improve drainage.
3. Plant the seedlings: Gently remove the seedling from its container and loosen any tangled roots. Place the seedling in the hole and backfill with soil, firming it gently around the roots.
4. Water well: Water the seedlings thoroughly after planting.
Caring for Your Osteospermum
Once you’ve planted your osteospermum, it’s important to provide them with proper care to ensure they thrive. Here are some tips:
- Sunlight: Osteospermum needs at least 6 hours of sunlight per day.
- Watering: Water regularly, especially during dry periods. Allow the soil to dry slightly between waterings.
- Fertilizing: Feed your osteospermum every few weeks with a balanced fertilizer.
- Deadheading: Pinch off spent flowers to encourage more blooms.
- Pinching: Pinch off the tips of the stems to encourage bushier growth.
Overwintering Osteospermum
Osteospermum is generally considered an annual plant, meaning it completes its life cycle in one growing season. However, in mild climates, you can try overwintering your osteospermum indoors. Here’s how:
1. Bring plants indoors: Before the first frost, bring your osteospermum plants indoors to a sunny location.
2. Prune plants: Prune back the plants by about half.
3. Repot if needed: If the plants are rootbound, repot them in a larger container.
4. Water sparingly: Allow the soil to dry slightly between waterings.
5. Provide light: Give your plants as much sunlight as possible.
Troubleshooting Common Osteospermum Problems
While osteospermum is relatively easy to grow, there are a few common problems that you may encounter. Here are some tips on how to address them:
- Pests: Osteospermum can be susceptible to aphids, whiteflies, and spider mites. Use insecticidal soap or neem oil to control these pests.
- Diseases: Watch out for fungal diseases, such as powdery mildew and leaf spot. Improve air circulation and avoid overhead watering to prevent these diseases.
- Wilting: Wilting can be caused by underwatering or overwatering. Check the soil moisture levels and adjust your watering schedule accordingly.
- Lack of bloom: If your osteospermum isn’t blooming, it may not be getting enough sunlight or it may need more fertilizer.
