How to prune scorzonera

Remove flower buds in year two before they open; remove dead foliage as needed. Pinch or cut flower stalks at the base before they open if growing for roots. Remove dead or damaged basal leaves by cutting cleanly at the stem. Roots can be left in the ground and harvested across autumn and winter.

In the second year, flower buds may appear — remove them promptly if you want to maximise root yield, as seed production diverts energy. Remove dead or yellowed leaves at the base throughout the season.
