Coreopsis, commonly known as tickseed, is a low-growing perennial that produces golden marigold-looking flowers. This plant is hardy in USDA zones 5 to 9. In full sun and well-drained soil, it also blooms for the better part of the growing season, especially if you promptly prune spent blooms. When the plant slows or stops its flower production, divide and replant. Dig coreopsis in spring or fall, but not during its blooming season.

Dig around the base of the coreopsis with a spade until you reach the area under the plant's root system.

Lift the plant out of the ground with the spade's blade. Place it on the soil surface.

Shake the coreopsis gently to get excess soil off the roots so you can see them as you cut.

Drive your spade into the clump of roots and slice it into quarters. Use your hands to separate and discard dead foliage that used to be in the centre of the plant.

Replant the coreopsis divisions at the same depth as they were before. Place them back in the same site or in a new one in full sun and with fast drainage.
