Strawflower Seed Pastel Mix (Xerochrysum bracteatum)

Growing Strawflowers

Soil Preparation

1. Soil Type: Strawflowers prefer well-draining soil with a pH between 6.0 and 7.0.
2. Soil Preparation: Work organic matter, such as compost, into the soil to improve its fertility and drainage. They thrive in soil that is not overly rich.

Planting

1. Direct Sowing:
   • Timing: Direct sow strawflower seeds after the last frost date when the soil temperature is consistently above 60°F (15°C). They can be started indoors 6-8 weeks before the last frost.
   • Spacing: Sow seeds ¼ inch deep in rows spaced 12-18 inches apart. Thin seedlings to 8-12 inches apart once they have grown a few inches tall.

Watering

1. Frequency: Keep the soil consistently moist until seeds germinate. After germination, water moderately, allowing the soil to dry out slightly between waterings.
2. Technique: Water at the base of the plants to avoid wetting the foliage.

Fertilizing

1. Initial Fertilization: Incorporate a balanced, slow-release fertilizer into the soil at planting time if needed.
2. Ongoing Fertilization: Strawflowers generally do not require additional fertilization beyond what is in the soil.

Care

1. Weeding: Keep the area around the plants weed-free to reduce competition for nutrients and water. Hand-pull weeds to avoid disturbing the shallow roots of the strawflower plants.
2. Mulching: Apply a layer of organic mulch around the plants to help retain soil moisture and suppress weeds.

Pests and Diseases

1. Pests: Watch out for aphids and spider mites. Use insecticidal soap or neem oil if infestations occur.
2. Diseases: Strawflowers are generally resistant to diseases but can be affected by fungal issues if the foliage is kept wet. Ensure good air circulation and avoid overhead watering.

Indoor Seed Starting

Materials Needed

• Seed starting trays or pots
• Seed starting mix
• Strawflower seeds
• Watering can or spray bottle
• Grow lights or a sunny windowsill
• Plastic wrap or a humidity dome

Steps

1. Timing: Start strawflower seeds indoors 6-8 weeks before the last expected frost date.
2. Fill Trays: Fill seed starting trays or pots with a high-quality seed starting mix.
3. Sow Seeds: Sow strawflower seeds on the surface of the seed starting mix. Lightly press them into the soil but do not cover them, as they need light to germinate.
4. Water: Moisten the soil gently with a watering can or spray bottle. Ensure the soil is damp but not waterlogged.
5. Cover: Cover the trays with plastic wrap or a humidity dome to retain moisture and create a warm environment.
6. Light: Place the trays under grow lights or in a sunny windowsill. Strawflower seeds need light to germinate and grow best with 14-16 hours of light per day.
7. Temperature: Maintain a consistent temperature of 65-75°F (18-24°C) for optimal germination.
8. Germination Time: Strawflower seeds usually take 10-14 days to germinate.
9. Watering: Keep the soil consistently moist but not waterlogged. Water from the bottom if possible to avoid disturbing the seedlings.

Transplanting

1. Timing: Once seedlings have developed 2-3 true leaves and the danger of frost has passed, harden them off by gradually exposing them to outdoor conditions over a week.
2. Spacing: Transplant the seedlings into the garden, spacing them 8-12 inches apart.

Harvesting

1. Timing: Strawflowers are typically ready to harvest 60-90 days after planting, depending on the variety and growing conditions.
2. Method: Harvest flowers when they are fully open but not yet fading. Cut the stems in the morning when the flowers are at their freshest, and place them in a cool, dry place to dry.

Storage

1. Preparation: After harvesting, trim the stems to your desired length.
2. Storage Conditions: Store dried strawflowers in a cool, dry place away from direct sunlight to maintain their color and shape. They can be used in arrangements or kept for decorative purposes.

By following these steps, you’ll be able to grow healthy, vibrant strawflowers and enjoy their beauty both in your garden and as part of your indoor decor.
