Growing and Maintenance Tips

Coreopsis is native to North America. It is an easy care plant requiring average soil, plenty of sun and good drainage. Dead heading regularly will encourage more bloom and shearing after the first round of flowering can encourage another flush of flowers. 'Zagbred' is quite tolerant of poor soils, including rocky and sandy soils. Crown rot can occur if it is grown in moist, poorly drained soil.
