Coreopsis, commonly referred to as Tickseed or Calliopsis, is a delightful addition to any garden due to its ease of cultivation and resilience. This guide will walk you through the essential steps and considerations for growing Coreopsis successfully in your garden, from seed to bloom.
Planting Guide
Coreopsis seeds can be started indoors in late winter, to be transplanted after the last frost, or directly sown into the garden when there's still a slight risk of frost. Coreopsis will thrive in Zone 4 and higher.
For gardeners in milder winter climates, consider a fall sowing to establish early growth. Seeds typically germinate between 5 to 25 days in soil maintained at 12-21°C (55-70°F), under bright light conditions.
Seed Sowing
Lightly sow the seeds on the soil surface and ensure they are not covered, as Coreopsis requires light for optimal germination. Once seedlings have been established, thin them to about 15cm (6 inches) apart to allow ample space for growth.
Care and Maintenance
Coreopsis is remarkably low maintenance but does benefit from regular deadheading to encourage continuous blooming throughout the growing season. Avoid fertilizing the plants, as excess nutrients can inhibit their flowering capability. This plant adapts well to various soil types, though it prefers well-drained, fertile ground.
Pest Resistance and Growth
One of Coreopsis's many strengths are its resistance to pests, diseases, and even deer, making it an excellent choice for gardens prone to wildlife visits. While it is a perennial that may self-sow, it spreads very slowly via underground rhizomes, making it manageable and non-invasive.
Growing Coreopsis offers many benefits, from its vibrant, daisy-like flowers that attract pollinators to its undemanding nature, making it ideal for novice and experienced gardeners.
With its ability to thrive under a variety of conditions and its minimal care requirements, Coreopsis is a stellar choice for adding long-lasting beauty to any small farm or home garden. Start planting Coreopsis this season to bring enduring charm and color to your outdoor spaces.
