Coreopsis grandiflora Mayfield Giant is a great choice for UK gardeners looking for a low-maintenance, long-blooming perennial.

How to care for your Coreopsis Mayfield Giant

  1. Planting: Should be planted in a location that receives full sun or partial shade. This plant is adaptable to a wide range of soil types, but it prefers well-draining soil. When planting, make sure to space the plants about 60-90cm apart to allow enough room for growth.
  2. Watering: This plant is drought-tolerant, so it does not require a lot of watering. However, during the first few weeks after planting, it is important to keep the soil consistently moist until the plant is established. After that, only water occasionally during prolonged dry spells.
  3. Fertilising: It is not particularly demanding in terms of fertiliser, but it may benefit from a light application of a balanced fertiliser in the Spring.
  4. Deadheading: This plant will continue to bloom throughout the summer and early fall if the spent flowers are regularly removed. Deadheading will also promote bushier growth.
  5. Winter care: It is a hardy plant, but it is best to cut back the spent foliage in late autumn to prevent the buildup of disease.

By following these simple care tips, you can enjoy the bright yellow flowers of Coreopsis Grandiflora Mayfield Giant in your UK garden for many Summers to come.
