The stunning blanket flower, also known as Gaillardia, is a flowering plant that is celebrated for its vibrant colors and resilience. Native to North America, this perennial plant thrives in various conditions, making it an excellent choice for gardens across the United States, including the unique climate of Alaska. In this article, we will explore how to successfully grow blanket flowers in Alaska, focusing on soil preparation, planting techniques, maintenance, and pest management.
Before diving into growing techniques, it’s essential to understand what blanket flowers are. They are characterized by their daisy-like blooms that come in various shades of red, orange, yellow, and even bi-color combinations. These flowers typically bloom from late spring through early fall and attract pollinators like bees and butterflies, making them an excellent addition to any garden.
Cold Hardiness: Blanket flowers are hardy plants that can tolerate cooler temperatures and are generally resistant to frost.
Low Maintenance: Once established, these flowers require minimal care. They thrive on neglect, making them ideal for busy gardeners.
Attractive & Vibrant: The bright colors of blanket flowers add a burst of color to gardens, particularly during the short Alaskan summer months.
Pollinator-Friendly: By attracting bees and butterflies, you contribute to the local ecosystem.
When growing blanket flowers in Alaska, the first step is choosing a suitable location in your garden. Look for a spot that receives full sun for at least six hours a day. Blanket flowers thrive in well-drained soil and will struggle in areas where water tends to pool.
Blanket flowers prefer sandy or loamy soils with a pH between 6.0 and 7.0. Before planting:
Test the Soil: Conduct a soil test to determine pH levels and nutrient content. Many garden centers offer soil testing kits.
Amend the Soil: If necessary, amend your soil with organic matter like compost or peat moss to improve drainage and nutrient availability.
Ensure Good Drainage: If your soil retains too much moisture, consider raised beds or planting on mounds to promote drainage.
Blanket flowers can be propagated through seeds or divisions. Here’s how to do both:
Timing: Start seeds indoors about 6–8 weeks before the last frost date for your area (usually around mid-April in many parts of Alaska). You can also sow seeds directly outdoors after the last frost.
Sowing Seeds Indoors: Use seed-starting trays filled with seed-starting mix. Sow seeds lightly on the surface and cover them with a thin layer of soil.
Watering: Keep the soil consistently moist but not soggy until germination occurs (typically within 10–14 days).
Transplanting: Once seedlings develop two sets of true leaves and are hardened off (acclimated to outdoor conditions), transplant them into the garden.
Timing: Early spring or early fall is the best time to divide established plants.
Dividing Plants: Carefully dig up clumps of blanket flowers and use a sharp spade or knife to separate them into smaller sections with roots attached.
Replanting: Replant immediately in well-prepared soil at a similar depth as they were growing before.
When planting blanket flowers, ensure adequate spacing to allow airflow between plants—this helps prevent fungal diseases commonly associated with overcrowding. Space plants about 12–18 inches apart.
While blanket flowers are drought-tolerant once established, they will benefit from regular watering during prolonged dry spells:
Establishment Phase: Water newly planted blanket flowers regularly until they establish deep root systems (usually within their first growing season).
Established Plants: After establishment, reduce watering frequency but keep an eye on dry spells; occasional deep watering can encourage stronger blooms.
Blanket flowers do not require heavy fertilization:
Initial Fertilization: When planting, you may incorporate a slow-release fertilizer into the soil.
Ongoing Fertilization: Lightly fertilize in spring with a balanced fertilizer (20-20-20) if necessary; avoid over-fertilizing as this can lead to leggy growth and reduced blooms.
Deadheading spent blooms encourages additional flowering throughout the season:
Regularly remove faded flowers by pinching them off at their base.
In fall or early spring, cut back dead foliage to prepare for new growth.
While blanket flowers are relatively pest-resistant, some issues may arise:
Aphids: These small insects suck sap from plants but can be controlled by releasing ladybugs or using insecticidal soap.
Slugs & Snails: They may munch on young foliage; handpick them or use traps baited with beer.
Spider Mites: These pests thrive in dry conditions; increase humidity level around plants or spray water on foliage regularly.
To prevent fungal diseases:
Ensure good air circulation between plants.
Water early in the day so that foliage dries quickly.
Avoid overhead watering whenever possible; water at the base of plants instead.
In Alaska’s harsh winters, proper care during the cold months is crucial for protecting your blanket flowers:
Mulching: Apply a layer of mulch (straw or shredded leaves) around your plants at the end of fall to insulate roots from freezing temperatures.
Cutting Back: In late fall or early spring, cut back dead perennials before new growth emerges.
Snow Cover: If snow is available during winter months, let it cover your garden as it acts as natural insulation against extreme cold.
Growing blanket flowers in Alaska can be a rewarding experience that enhances your garden’s beauty while supporting local wildlife. By understanding their needs regarding soil preparation, planting techniques, maintenance practices, pest management strategies, and winter care tips, you can cultivate these vibrant perennials successfully even in challenging climates. With proper care and attention, your Alaskan garden will burst with color each summer as these resilient blooms flourish under the midnight sun!
