Harvest Tips
Hostas are ornamental foliage plants; no traditional harvest. Cut flower spikes once blooms fade if desired. In fall, allow foliage to naturally decline before cutting stems to ground level in late November or early December. Do not cut back too early as leaves continue to photosynthesize and store energy for next season.
Fun Facts
