Rooting Coleus Cuttings in Autumn: Tips for Success Despite Low Light

Coleus root easily, but autumn’s short days and cool temperatures reduce success. The process relies on auxins, plant hormones that initiate roots at stem nodes.

For best results: take cuttings just below a node, leave only the top four leaves, and place in water or moist medium. Provide bright light—northern exposure is insufficient. A south-facing window or grow lights (14 hours/day) are ideal. Avoid drafts, which can kill cuttings.
