Cultivating Coreopsis
Choosing the Right Location
Coreopsis thrives in full sun, but it can tolerate some light shade. Well-drained soil is essential to prevent root rot.
Planting
Seed Sowing: Coreopsis can be propagated by seed, either directly in the garden or in seed trays. Sow seeds in spring after the last frost.
Transplanting Seedlings: Once seedlings have developed a few sets of true leaves, they can be transplanted into the garden.
Dividing Established Plants: Established Coreopsis clumps can be divided every 3-4 years to rejuvenate the plants and propagate new ones.
Watering: While Coreopsis is drought-tolerant, regular watering, especially during dry periods, will promote healthy growth and abundant blooms.
Fertilizing: Coreopsis generally doesn’t require heavy fertilization. However, applying a balanced, slow-release fertilizer in early spring can provide additional nutrients.
Deadheading: Regular deadheading, or removing spent blooms, encourages continuous flowering throughout the season.
Winter Protection: In colder climates, it’s advisable to mulch Coreopsis plants in late fall to protect them from harsh winter conditions.
