Deadhead spent blooms on growing coreopsis often for the production of more flowers. Growing coreopsis may be cut back by one-third in late summer for a continued display of blooms. Youll enjoy this reliable wildflower for long lasting beauty and the simplicity of how to care for coreopsis flowers.
Secondly, how do you look after coreopsis? Coreopsis will need regular water when first planted until they are established. After that, they are drought tolerant. Water the plants deeply at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface (stick your finger in the soil to check.)
Similarly, you may ask, should coreopsis be cut back?
Coreopsis grown as a perennial should be cut back after the summer growing season. Cut back one-third to one-half of the plants height. Pruning should not extend into the older brown woody growth, as this may kill the plant, according to the University of California Cooperative Extension.
Does coreopsis die back in winter?
Like many perennials, coreopsis has gone to seed and has stopped blooming by mid-September. The urge may be to start pulling and cutting everything, but, like many others, coreopsis will winter better if left alone to die off on its own.
