  • water dropWater

    Tickseed prefers regular watering, especially during dry spells, but it is also quite drought tolerant once established. Generally, you should aim to water it once a week with about 1-1.5 inches of water. During extremely hot or dry periods, increase the watering frequency to twice a week, ensuring the soil doesn't dry out completely. It's best to water deeply at the base of the plant early in the morning or evening to reduce evaporation. Use a soaker hose or drip irrigation for the most efficient water usage, providing the plants with approximately 2 gallons per watering session to encourage deep root growth.

  • sunLight

    Tickseed thrives in full sun, meaning it should receive at least 6 to 8 hours of direct sunlight each day. The best spot for planting tickseed is in an open location where it can bask in uninterrupted sunlight throughout the day. While it can tolerate some light shade, the plant will produce fewer flowers and may become leggy as it stretches for the light.

  • thermometerTemperature

    Tickseed prefers a temperature range between 60 and 75 degrees Fahrenheit but can survive in temperatures as low as 32 degrees and as high as 90 degrees Fahrenheit. The ideal temperature conditions allow the plant to produce its vibrant flowers and maintain healthy growth. Avoid planting in areas where temperatures regularly dip below freezing for extended periods to prevent damage to the plant.

  • scissorsPruning

    Pruning tickseed is crucial for promoting a bushier growth and more blooms. Deadheading, or removing spent flowers, should be done regularly throughout the flowering season to encourage continuous blooming. Additionally, cut back the plants by one-third in midsummer to rejuvenate and stimulate new flower production. The best time for a more substantial pruning is in the late fall or early spring to help maintain the plant's shape and overall health.

  • circleLife cycle

    Coreopsis tinctoria, commonly known as plains coreopsis or golden tickseed, begins its life cycle as a seed that germinates in the spring, sending up a small rosette of leaves at the soil surface. As the plant matures, it develops a slender, upright stem and branching occurs, eventually bearing numerous daisy-like flowers with yellow rays and reddish-brown centers throughout the summer. After pollination, typically by insects, the flowers produce small, dry fruits called achenes. When the achenes mature, they are dispersed by wind, water, or animal movement, allowing the plant to colonize new areas. The entire life cycle from germination to seed dispersal can occur in one growing season, as plains coreopsis is an annual plant. With the advent of winter, the parent plant dies, completing its life cycle, while the seeds remain dormant until the following spring when they can germinate to start the process anew.

      Spring-early summer

    • Coreopsis tinctoria, commonly known as Plains Coreopsis or Golden Tickseed, is most commonly propagated by seed. The prime time to sow seeds directly into the garden is in the spring after the threat of frost has passed. To encourage germination, seeds should be lightly pressed into the soil but not covered as they require light to germinate. Once sown, the area should be kept moist until germination, which usually occurs within 2-3 weeks. Transplanting has a high success rate too if the seedlings are started indoors in trays around 4 to 6 weeks before the last frost date and then moved outside when the weather stabilizes.
