How to Care for the Plant

Water
Penstemons are very drought tolerant perennials that are easy to grow and are rarely bothered by insects or diseases. Water as needed.
Pruning
Penstemons are short-lived perennials that can suffer in winter. To avoid losses, don't cut back plants until spring. Take summer cuttings to prevent winter losses.
Fertilizer
Feed beardtongue plants once a year with an organic fertilizer, applied in the fall. Feeding these flowers with conventional bloom-boosting formula can promote too much growth and can shorten the life of the plants.
