Chrysanthemum maximum, often known as Shasta daisy, is a classic perennial flower known for its cheerful, daisy-like blooms. The "Alaska" variety typically features large, white flowers with a bright yellow center, adding a clean, crisp look to your garden. If you're interested in growing this variety from seeds, here’s a comprehensive guide:
Growing Chrysanthemum Maximum 'Alaska':
**1. ** Planting Time:
-
Indoor Sowing: Start seeds indoors 6-8 weeks before the last frost date. This will give the plants a head start and ensure they are ready to be transplanted outdoors once the weather warms up.
-
Outdoor Sowing: Direct sow seeds outdoors after the last frost date. This is usually in late spring or early summer, depending on your local climate.
**2. ** Soil Requirements:
-
Soil Type: Chrysanthemums prefer well-draining soil rich in organic matter. Loamy or sandy soil works best.
-
pH Level: Aim for a slightly acidic to neutral pH (6.0-7.0).
**3. ** Sunlight:
-
Light Needs: Full sun is ideal for Chrysanthemum maximum. Choose a location that receives at least 6-8 hours of direct sunlight per day.
**4. ** Watering:
-
Moisture Needs: Keep the soil consistently moist but not waterlogged. Water the plants when the top inch of soil feels dry. Overwatering can lead to root rot, so ensure good drainage.
**5. ** Spacing:
-
Planting Distance: Space plants about 12-18 inches apart to allow for their growth and to ensure good air circulation.
**6. ** Care:
-
Deadheading: Regularly remove spent flowers (deadhead) to encourage more blooms and extend the flowering period.
-
Pruning: In the spring, cut back any dead or damaged growth to promote healthy new growth.
**7. ** Pests and Problems:
-
Common Issues: Watch for common pests such as aphids, spider mites, and snails. Fungal diseases like powdery mildew can also affect chrysanthemums, so ensure good air circulation and avoid overhead watering.
-
Prevention: Proper spacing, well-draining soil, and avoiding overhead watering can help prevent many issues.
Sowing Seeds:
**1. ** Indoor Sowing:
-
Seed Starting: Sow seeds on the surface of a seed-starting mix. Gently press them into the soil but do not cover them deeply as they need light to germinate.
-
Temperature: Maintain a temperature of about 70°F (21°C) for germination.
-
Light: Provide bright, indirect light or use grow lights if necessary.
**2. ** Outdoor Sowing:
-
Sowing Method: Scatter seeds on the prepared soil and lightly cover with a thin layer of soil.
-
Moisture: Keep the soil consistently moist until seeds germinate. Germination usually takes 2-3 weeks.
Harvesting and Storage:
-
Seed Collection: If you want to collect seeds, allow the flower heads to dry on the plant. Once the seed heads are completely dry, collect the seeds and store them in a cool, dry place in an airtight container.
Additional Tips:
-
Winter Care: In colder climates, provide mulch around the base of the plants to protect the roots over winter.
-
Companion Planting: Chrysanthemums make great companions for other garden flowers and can help repel pests.
With the right conditions and care, Chrysanthemum maximum 'Alaska' will bring bright and cheerful blooms to your garden. Enjoy growing these beautiful flowers
