Calendula (Calendula officinalis), often known as pot marigold, is a popular annual known for its bright, cheerful flowers and medicinal properties. The Neon Red Flame variety is particularly striking with its vivid, fiery red blooms. Here’s a comprehensive guide to growing Calendula Neon Red Flame from seeds:
Growing Calendula Neon Red Flame:
**1. ** Planting Time:
-
Indoor Sowing: Start seeds indoors 6-8 weeks before the last expected frost. This helps give the plants a head start before transplanting them outdoors.
-
Outdoor Sowing: Direct sow seeds outdoors in early spring, as soon as the soil can be worked, or in late summer to early fall for fall and winter blooms in milder climates.
**2. ** Soil Requirements:
-
Soil Type: Calendulas prefer well-draining soil that is rich in organic matter. A loamy or sandy soil is ideal.
-
pH Level: They thrive in slightly acidic to neutral soil (pH 6.0-7.0).
**3. ** Sunlight:
-
Light Needs: Calendulas need full sun to thrive. Ensure they receive at least 6-8 hours of direct sunlight per day.
**4. ** Watering:
-
Moisture Needs: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry. Calendulas are somewhat drought-tolerant but perform best with regular watering, especially during dry spells.
**5. ** Spacing:
-
Planting Distance: Space plants about 8-12 inches apart. This spacing allows for their natural growth and helps prevent overcrowding.
**6. ** Care:
-
Deadheading: Regularly remove spent flowers (deadhead) to encourage more blooms and prolong the flowering period.
-
Fertilization: Fertilize with a balanced, all-purpose fertilizer once or twice during the growing season. Avoid excessive fertilization, which can lead to lush foliage but fewer blooms.
**7. ** Pests and Problems:
-
Common Issues: Calendulas are relatively pest-resistant but can sometimes be affected by aphids, slugs, or powdery mildew. Ensure good air circulation and avoid overhead watering to reduce the risk of fungal diseases.
-
Prevention: Good garden hygiene, proper spacing, and well-draining soil are key to preventing many issues.
Sowing Seeds:
**1. ** Indoor Sowing:
-
Seed Starting: Sow seeds on the surface of a seed-starting mix. Lightly press them into the soil but do not cover them deeply, as they need light to germinate.
-
Temperature: Maintain a temperature of about 65-70°F (18-21°C) for germination.
-
Light: Provide bright, indirect light or use grow lights if necessary. Germination typically takes 7-14 days.
**2. ** Outdoor Sowing:
-
Sowing Method: Scatter seeds on prepared soil and lightly cover with a thin layer of soil or compost.
-
Moisture: Keep the soil consistently moist until seeds germinate, which usually takes 7-14 days.
Harvesting and Storage:
-
Seed Collection: If you wish to collect seeds, allow the flowers to mature and dry on the plant. Once dried, remove the seeds and store them in a cool, dry place in an airtight container.
Additional Tips:
-
Companion Plants: Calendulas work well in flower beds, borders, and containers. They pair nicely with other annuals and perennials, such as marigolds and zinnias.
-
Winter Care: In colder climates, Calendulas are typically grown as annuals. In milder climates, they can self-sow and return the following year.
By following these guidelines, you should be able to enjoy a vibrant display of Calendula Neon Red Flame in your garden. Their bright, fiery blooms will add a bold touch of color and cheerfulness.
