Feeding and Fertilizing

Lanceleaf Coreopsis is not a heavy feeder, but occasional feeding can promote growth.

  • Initial Feeding: Apply a balanced slow-release fertilizer in early spring as new growth begins. A formula with an equal ratio of nitrogen, phosphorus, and potassium (such as 10-10-10) is ideal.

  • Supplemental Feeding: If planted in less fertile soil, a mid-season application of a liquid fertilizer at half strength can help promote vigorous growth and enhance blooming.

  • Avoid Over-Fertilization: Be cautious not to over-fertilize, as too much nitrogen can lead to lush foliage at the expense of flowers.

  • Soil Requirements: Prefers well-drained, moderately fertile soil. Coreopsis lanceolata is drought-tolerant once established, making it adaptable to various garden environments.

  • Bloom Enhancement: Adequate feeding can lead to a more prolific bloom period, ensuring a vibrant display of its characteristic yellow flowers throughout the season.

Seasonal Care

Coreopsis lanceolata, commonly known as lanceleaf coreopsis or lance-leaved coreopsis, is a vibrant perennial wildflower native to North America. It's renowned for its bright yellow flowers that bloom prolifically from late spring to early summer, making it a popular choice for meadows, prairie gardens, and traditional flower borders. This species is particularly valued for its ease of care, drought tolerance, and ability to attract pollinators such as bees and butterflies. Here's how to care for Coreopsis lanceolata throughout the seasons:


Spring

  • Cleanup: Clear away any debris and dead foliage from the previous year to make room for new growth. Early spring is also a good time to divide plants if they have become too crowded.

  • Planting: Plant Coreopsis lanceolata in a sunny spot with well-drained soil. It can tolerate a variety of soil types, including poor soils, but good drainage is essential to prevent root rot. Spring is a good time to plant or divide this perennial to give it a full season to establish.
